Household Income: The Forms It Takes and Why the Form Matters

Household income is every rupee that actually arrives, and the form it arrives in settles more than the size of it. A salary comes on a fixed date, is cut before it lands, and carries somebody else's document behind it. A counter's takings come when they come, and nobody outside the household wrote them down. Form decides timing and proof, and those two run a household's year. Sort by form first.

Here is what sits underneath that. Two households can take exactly the same amount of money across a year and have completely different years, and the reason is never the amount. The difference is that one of them knows the date, to the day, on which the money will be there, and the other finds out on the day. Then add a second difference on top. One of them can hand a stranger a piece of paper that proves the money arrived, and the other can only say so. The two properties, when the money comes and who can vouch for it, do more work in an ordinary month than the size of the number ever does.

One household carries every example. Meghna Bhosale is salaried at Sahyadri Freight Services Private Limited. Ashok Bhosale runs a tailoring counter in a market lane, and what the counter takes changes every month. Ira Bhosale is seven and in school. Money that is income comes apart from money that only looks like it, a payslip runs from its top figure down to the one that reaches the account, two properties decide how an income behaves, a year of counter takings is stated month by month instead of on average, and the household's own idea of its income turns out wider than the idea anybody outside the household will work with.

What actually counts as household income, and what only looks like it?

Income is money that arrives from outside the household and leaves the household holding more than it held before. The second half of that sentence is the whole test, and it is the half that gets dropped. Plenty of entries on a bank statement are money arriving. Only some of them are income.

Look at three entries on the Bhosale household's statement for the year. On the 15th of every month, Rs 2,000/- leaves the salary account for the recurring deposit. On 17 April, Rs 4,000/- arrives in the salary account from the second savings account the household keeps as a buffer. On 29 March, Rs 18,600/- arrives from the insurer, reimbursing in full a hospital payment the household had made on 8 February out of that same buffer. Two of those three are money arriving. None of the three is income. The Rs 2,000/- is the household's money moving to another place the household keeps it. The Rs 4,000/- is the same rupees walking back the other way. The Rs 18,600/- is a return of money that had already left. The year's totals are unchanged by it.

A household's own money can arrive in one of its own accounts all day without the household being a single rupee better off, so money arriving is not the test. A bank statement cannot tell the difference and will never try, and the distinction comes before everything else. A statement records movement. Whether a movement is income is a question the household answers, using knowledge the bank does not have.

Three things did arrive from outside the household this year. Meghna Bhosale's take-home pay of Rs 39,800/- was creditedThe moment money appears in an account and can be used. Money can be sent days before it is credited, and it is the crediting that a household actually feels. on the 1st of each month, Rs 4,77,600/- across twelve months. Ashok Bhosale's counter takings were moved into the salary account in one lump at the end of each month, Rs 96,000/- across twelve months. And Rs 1,180/- of interest was credited on the buffer savings account across the year. Nobody worked for that interest and nobody decided it. Rs 5,74,780/- in total, and the three arrived in three entirely different ways.

Why does the form income arrives in matter more than the amount?

Take two people doing identical work for identical money. The first is paid Rs 3,000/- on the first working day of every month, without having to ask. The second is paid Rs 3,000/- when the customer gets round to it. Payment lands sometimes on the 3rd, sometimes on the 26th, and twice a year in the following month. Across a year they take the same Rs 36,000/-. The two years are not the same. There is no date for the second one to plan around, so the second one spends attention every single month on a question the first one never has to ask.

Two properties separate one form of income from another and neither of them is the amount: when it arrives, and whether anybody outside the household can confirm that it did. Call them timing and proof. Outgoings leave on dates that were set by somebody else, and those dates do not move when the money is late. Timing decides whether a particular month works. Proof decides what the income can do in any conversation with an outsider. Outside the front door a household is not asked what it takes. A household is asked what it can show.

Every form of income sits somewhere on those two properties, and the forms are taken one at a time below. The two are independent of each other. A pension is strong on both. Money sent by relatives is weak on both. A counter's takings are weak on timing and can be made strong on proof, but only by the household, and only by writing it down while it is happening.

What is the difference between gross pay and what reaches the account?

A payslip carries two totals, and they are usually the two figures furthest apart on the slip. Gross payThe whole figure at the top of a payslip, before anything is taken off. Gross pay is the figure in an offer letter and the one people say out loud. sits at the top. The gross figure is what gets said when somebody asks what the job pays. Take-home payWhat actually reaches the bank account after every deduction has been taken off. Take-home pay is the only figure a household can spend. sits at the bottom. Take-home pay alone reaches the account.

On Meghna Bhosale's invented payslip, gross pay is Rs 46,000/- a month. Three amounts come off before the money moves: provident fund Rs 3,120/-, professional tax Rs 200/-, and tax deducted Rs 2,880/-. The three add to Rs 6,200/-. The credit on the 1st is Rs 39,800/-. Each of the three is a deduction at sourceMoney removed from pay by the employer before the pay arrives, so the household never holds it and never sees it in the account.. The employer takes it off and sends it on, and the household never holds it for a moment.

ONE PAYSLIP, TWO TOTALS. THE HOUSEHOLD LIVES ON THE LOWER ONE. Figures for one month, with the rule behind each deduction named lower down. PAYSLIP Sahyadri Freight Services Private Limited, invented MEGHNA BHOSALE, ONE MONTH EARNINGS Gross pay Rs 46,000/- a payslip usually lists several earnings lines that add to this DEDUCTIONS, TAKEN BEFORE THE MONEY MOVES Provident fund Rs 3,120/- Professional tax Rs 200/- Tax deducted at source Rs 2,880/- Total deductions Rs 6,200/- NET PAY, CREDITED ON THE 1ST Rs 39,800/- 1. THE FIGURE PEOPLE SAY OUT LOUD Rs 46,000/- is a real figure and it is never the figure that arrives in any account. 2. THREE SUBTRACTIONS, MADE BY THE EMPLOYER Provident fund, professional tax and tax deducted come off before the pay moves. What sets each one is named lower down, and no rate is here. 3. Rs 6,200/- NEVER TOUCHES THE ACCOUNT It has gone before the money is credited, so no plan can spend it and no month contains it. 4. Rs 39,800/- IS THE HOUSEHOLD FIGURE This is what lands on the 1st, twelve times a year, and it is the only salary figure that is spendable.
On this invented payslip, gross pay of Rs 46,000/- less provident fund Rs 3,120/-, professional tax Rs 200/- and tax deducted Rs 2,880/- leaves take-home pay of Rs 39,800/-, and only that last figure ever reaches the account.
The payslip, one month, inventedAmount
Gross payRs 46,000/-
Less provident fundRs 3,120/-
Less professional taxRs 200/-
Less tax deducted at sourceRs 2,880/-
Total deductionsRs 6,200/-
Take-home pay, credited on the 1stRs 39,800/-

The gap between the two totals is Rs 6,200/- a month and Rs 74,400/- a year, and a household that plans against the top figure is planning against money that has already gone somewhere else. Two of the three subtractions are not losses in any ordinary sense. The provident fund amount is the household's own money being held somewhere it cannot be spent, and the tax deducted is a payment towards a bill that would otherwise arrive later in one piece. But whatever they are on their way to becoming, they are not in the account on the 2nd, and a month is lived out of the account.

What sets each line on an Indian payslip

A payslip in India usually carries the same three deductions the Bhosale household sees. Provident fund is deducted under the rules of the scheme itself, professional tax is levied by the state government where the work is done and not by every state, and tax deducted at source is administered by the Central Board of Direct Taxes, at incometaxindia.gov.in. Each of the three is worked out by a rule that changes from time to time, and the rupee amounts on this payslip are illustrative.

Meghna Bhosale's gross pay is Rs 46,000/- and her take-home pay is Rs 39,800/-. Which figure belongs in the household's own arithmetic for the month?

Financial Literacy Bootcamp — Fin Maverick

What does a salary bring with it that a counter's takings do not?

Ashok Bhosale's tailoring counter took Rs 96,000/- across the twelve months. The Rs 96,000/- is the counter's takingsWhat a small trade collects from its customers before its own costs, such as materials and rent, are taken out of it., what customers handed over, and not the same thing as what the counter earned. Cloth, thread, lining, needles and the rent of the lane counter all come out of that Rs 96,000/- before anything belongs to the household. No figure exists for those costs. The counter has no account of its own, so the takings and the household money share one column on one statement, and nobody has ever separated the two.

Set the two forms side by side and the differences are not about size at all. The salary arrives on a date the employer fixed, in an amount the employer already calculated, with a document behind it that a stranger will read. The takings arrive when the customers come, in an amount nobody knew in advance, with no document behind them at all unless the household writes one. The counter's money is irregular incomeMoney that arrives in amounts and on dates nobody can predict in advance, so no single figure describes what the next month will bring., and irregular is a description of its behaviour rather than a comment on the work.

SAME HOUSEHOLD, TWO FORMS OF INCOME, FOUR ROWS THAT DIFFER Read across each row. Not one of the four differences is about how large the money is. A SALARY: Rs 39,800/- TAKE-HOME COUNTER TAKINGS: Rs 96,000/- A YEAR WHEN IT ARRIVES The 1st of every month, a date the employer fixed and the household never has to chase. Through the month as customers come, moved into the account in one lump at month end. WHO WROTE IT DOWN The employer, on a payslip, and the bank, as a credit entry on the statement. Nobody, unless the household writes it down on the day the customer pays. DOES THE AMOUNT MOVE No. Rs 39,800/- twelve times, the same figure in the thin months and the good ones. Yes, and by a lot. Rs 1,600/- in March and Rs 19,600/- in November, twelve times over. WHAT THE HOUSEHOLD HAS TO SUPPLY ITSELF Nothing. The pay arrives and the record of it arrives with it, whoever is watching. The whole record. Kept daily it is a year of evidence. Not kept, it cannot be rebuilt later.
A salary is dated by the employer and evidenced by somebody else, while the counter's takings arrive on no fixed date and are evidenced only by what the household writes down as it happens.

Ashok Bhosale's counter took Rs 19,600/- in November, its largest month. Is that Rs 19,600/- of household income for November?

Portfolio Management Bootcamp — Fin Maverick

Which other forms does household income take?

Most households have more than two forms of money arriving, and the extra ones are easy to leave out of the reckoning precisely because nobody has to do anything to make them appear. Interest is the clearest case. The Bhosale household's buffer savings account was credited Rs 1,180/- of interest across the year, roughly Rs 98/- a month, arriving without a decision, without a date anybody noticed, and without a single conversation. The interest is income. The interest is also small enough to change nothing about how any month went, and both statements can be true at once.

Beyond salary, takings and interest there are four more forms an ordinary household meets. Rent, if a room or a shop is let out, has an agreed date that holds only as long as the person paying it holds to it. A pension behaves almost exactly like a salary. Money sent by relatives is real money and arrives on nobody's timetable. And one-offs: a reimbursement, a refund, the sale of something the household already had. Every one of these seven forms can be placed on the same two properties, and once a form is placed the household knows what to expect from it without having to think about it again.

SEVEN FORMS, TWO PROPERTIES, AND NOTHING ELSE TO REMEMBER A form placed once on these two columns behaves the same way every year after. THE FORM MONEY ARRIVES IN ARRIVES ON A DATE SOMEBODY ELSE FIXED CARRIES A DOCUMENT SOMEBODY ELSE WROTE Salary from an employer YES, THE 1ST YES, A PAYSLIP Takings from a small trade NO FIXED DATE ONLY IF WRITTEN DOWN Interest credited on savings YES, A BANK CYCLE YES, THE STATEMENT Rent from letting a room AGREED, NOT CERTAIN ONLY IF WRITTEN DOWN A pension YES, A SET DATE YES, A PAYMENT ADVICE Money sent by relatives NO FIXED DATE NO, ONLY THAT IT CAME A one-off, such as a refund NO, AND NOT AGAIN NO, AND IT REPEATS NEVER THE SECOND COLUMN IS THE ONE A HOUSEHOLD HAS TO SUPPLY ITSELF, AND ONLY WHILE IT IS HAPPENING. Colour repeats what the words say: green is settled by somebody else, lime is conditional, red is neither. Seven forms an ordinary household meets. The Bhosale household has three of them.
Salary, takings from a trade, interest, rent, a pension, money sent by relatives and one-off arrivals are seven forms of income, and each behaves differently on exactly two properties rather than on size.

Why does the day money arrives decide whether a month works?

A month has two timetables running through it and they were written by different people. Money arrives on one of them. Money leaves on the other. Neither timetable consults the other, and the household lives in the gap between them. A year has no dates in it, so timing is the part of income that never appears in any yearly figure.

Watch April in the Bhosale household's salary account. The account opened the month holding Rs 6,200/-. Take-home pay of Rs 39,800/- is credited on the 1st, taking the account to Rs 46,000/-. Rent of Rs 14,000/- leaves on the 5th. The two-wheeler instalment of Rs 3,150/- leaves on the 7th. The first school term of Rs 9,600/- and the society maintenance of Rs 1,200/- leave on the 10th. Mobile and broadband on the 12th, clothes for the school year on the 14th, the recurring deposit of Rs 2,000/- on the 15th, electricity on the 18th. Groceries, fuel and eating out take about Rs 3,725/- a week throughout. By the 22nd the account holds Rs 555/-. The counter money for April, Rs 7,200/-, is transferred in on the 30th.

The account is at its thinnest in the last week of a month in which nothing went wrong and the year as a whole ended ahead, and the reason is timing alone. No month in the year is unusual and nobody mismanaged anything. One income arrives on the 1st and the other on the 30th. The largest outgoings all leave between the 5th and the 15th. Any household holding those two timetables together will be thinnest at the same point every month, and knowing the shape of it in advance is different from being able to change it.

TWO TIMETABLES IN ONE MONTH: WHEN MONEY ARRIVES AND WHEN IT LEAVES The salary account through April, invented. One income lands on the 1st and the other on the 30th. Rs 46,000/- Rs 20,000/- Rs 0 Rs 39,800/- of salary is credited on the 1st. Rent Rs 14,000/- on the 5th, instalment Rs 3,150/- on the 7th. School term Rs 9,600/- and maintenance Rs 1,200/- on the 10th. Recurring deposit Rs 2,000/- on the 15th. THE LAST WEEK OF THE MONTH By the 22nd the account holds Rs 555/-. The counter money for April, Rs 7,200/-, is transferred in on the 30th. minus Rs 3,170/- on the 24th 1 5 10 15 20 25 30 Day of April. Every amount is invented and belongs to this household. Groceries, fuel and eating out take about Rs 3,725/- a week.
Salary lands on the 1st, rent leaves on the 5th, the instalment on the 7th and the school term on the 10th, while the counter money does not arrive until the 30th, so the account is thinnest in the last week of the month.

April is worth following to the end of the month rather than stopping at the 22nd. On the 24th the week's groceries, fuel and eating out of Rs 3,725/- took the account to minus Rs 3,170/-, where it stayed for six days until the counter money arrived on the 30th, and this was after the household had already moved Rs 4,000/- across from the buffer on the 17th. The year as a whole ended ahead. April still ran out, and it ran out in the last week rather than the first. The timing is a fact about dates and not about the size of anybody's income. The cost of an account below zero, and the way that charge is built, is covered separately.

Which two properties of an income matter more than its size?

Money arrives on one timetable and leaves on another. See what the date decides.

How is an income that changes every month stated?

One question breaks most household arithmetic, and it is not a hard question until it has to be answered in one number. Somebody asks what Ashok Bhosale earns from the counter. The twelve months, as they actually fell, were Rs 7,200/-, Rs 12,400/-, Rs 5,600/-, Rs 4,800/-, Rs 6,400/-, Rs 8,800/-, Rs 14,200/-, Rs 19,600/-, Rs 9,400/-, Rs 3,600/-, Rs 2,400/- and Rs 1,600/-. The twelve add to Rs 96,000/-, and Rs 96,000/- divided by twelve is Rs 8,000/-.

The average of those twelve months is Rs 8,000/- and not one of the twelve months was Rs 8,000/-. An average is a fact about a set of numbers rather than a description of any member of it, and the mismatch is neither a coincidence nor a surprise. The nearest months are April at Rs 7,200/- and September at Rs 8,800/-, each Rs 800/- away on either side. The lowest month is Rs 1,600/- and the highest is Rs 19,600/-, twelve times as large. A single figure sitting in the middle of that spread is arithmetically correct and says almost nothing about what any given month will bring.

TWELVE MONTHS AT THE COUNTER, AND AN AVERAGE THAT DESCRIBES NONE OF THEM Invented takings for one tailoring counter. The scale runs from zero to Rs 20,000/-. 7,200 12,400 5,600 4,800 6,400 8,800 14,200 19,600 9,400 3,600 2,400 1,600 AVERAGE Rs 8,000/- A MONTH and no month reached it THE TWO MONTHS CLOSEST TO THE LINE April took Rs 7,200/-, Rs 800/- under it. September took Rs 8,800/-, Rs 800/- over it. Nothing at all lands on the line itself. Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar Numbers above the bars are rupees. Lowest Rs 1,600/- in March, highest Rs 19,600/- in November, twelve times as large.
The counter's twelve months run from Rs 1,600/- to Rs 19,600/- and the average of Rs 8,000/- passes between the bars without touching any of them, the nearest being Rs 800/- away on either side.

There is a second figure worth knowing, and it is the one that gets left out. Line the twelve months of household money in from smallest to largest and the median monthThe middle month when the twelve are lined up from smallest to largest. With twelve months there are two in the middle, so the median is the point halfway between them. sits at Rs 46,600/-. The median month is Rs 1,200/- below the average of Rs 47,800/-. The average is pulled upward by two big months, November at Rs 59,400/- and October at Rs 54,000/-. The median counts months rather than rupees and is not pulled upward at all. Neither figure is wrong. The two answer different questions, and a household that knows only the average has been handed the one that the good months moved.

Twelve monthsRs 96,000/-Rs 5,73,600/-seven below, five above

Money in for a month is take-home pay of Rs 39,800/- plus that month's counter takings, and the twelve add to Rs 5,73,600/-, an average of Rs 47,800/-. The Rs 1,180/- of interest is not in this table because it was credited on the buffer savings account and never passed through the monthly flow at all. Read the right hand column and something becomes visible that the average hides completely. The five months above the line are above it by Rs 24,400/- in total. The seven months below the line are below it by Rs 24,400/- in total. The matching totals are not a happy accident. Matching is the definition of an average, and it is also the reason an average can never tell a household which months it will be short.

Money in averaged Rs 47,800/- a month across the twelve months. Before the line below moves, how many of the twelve months actually reached Rs 47,800/-?

Play with it

Move the line to whatever figure the household writes down as its monthly income, and count the months that reach it.

Every bar is one month of money in: take-home pay of Rs 39,800/- plus that month's counter takings. The salary never moves, so the height above the base is the counter alone. The line starts at Rs 47,800/-, the twelve month average, where five months reach the line and seven fall below it, the shortfall in those seven adds to Rs 24,400/-, and the longest run of months below the line without a break is three. The lowest month is Rs 41,400/- in March and the highest is Rs 59,400/- in November.

Jump the line to a figure a household might actually write down:

Educational illustration. One household across one year. Take-home pay is held at Rs 39,800/- in every month and only the counter takings move, so each bar is Rs 39,800/- plus that month's takings. The Rs 1,180/- of interest credited on the buffer savings account never passed through the monthly flow and is not in any bar.

What makes an income provable, and to whom?

Proof is the second property, and it only ever matters when somebody outside the household asks. Inside the front door, everybody knows what the counter took last Tuesday. Outside it, provable incomeIncome that somebody outside the household would accept evidence of, rather than income the household knows perfectly well it received. means income that a stranger can satisfy themselves about without taking anybody's word for it, and the difference between the two ideas is what proof actually means.

Meghna Bhosale's salary is proved twice over without her doing anything. The employer issues a payslip every month, and the bank records a credit of Rs 39,800/- on the 1st on a statement the bank itself produces. Two separate parties, neither of them the household, wrote both records down. Ashok Bhosale's Rs 96,000/- has nothing of the kind behind it. The takings arrive as cash and as small transfers over a month, they go into the salary account in one lump at month end, and the only entry anywhere is a transfer that looks exactly like any other transfer.

A salary is proved by documents somebody else was always going to write, and a small trade is proved only by the record the household keeps as the money comes in. The proof has to be created on the day or it cannot be created at all. None of that carries a judgement. Counters, stalls and workshops all over the country run on cash and keep no daily book, for perfectly ordinary reasons: the day is long, the amounts are small, and nothing about the work stops if the book is never opened. The cost of not keeping it is not a fine and not a charge. The cost arrives much later, on the day somebody asks what the counter takes and the honest answer is that the household knows and cannot show. Then a year of real work has to be rebuilt from memory, entry by entry, against a statement where a customer's payment and a grocery bill sit in the same column.

Try it out

The counter took Rs 96,000/- last year. What would actually make that figure provable to somebody outside the household?

Who else reads a household's income, and what do they do to the number?

Every rupee that arrives is real and gets spent on real things. A household counts all of them. Somebody outside the household counts something narrower. The outsider is not being difficult and is not doubting anybody. The outsider is answering a different question: not what came in, but what can be shown to have come in and can be expected to come in again. The two questions have different answers on the same set of facts, and neither answer is the wrong one.

Run the Bhosale household's year through that narrowing and watch what happens to it. Everything that arrived is Rs 5,74,780/-. Take out the Rs 96,000/- of counter takings, not because the money is not real but because no document outside the household records it, and Rs 4,78,780/- is left. Take out the Rs 1,180/- of interest, recorded by the bank but arriving once across a year rather than on any repeating date, and Rs 4,77,600/- is left. The Rs 4,77,600/- is the take-home salary, twelve times Rs 39,800/-, and every rupee of it has a payslip and a statement entry standing behind it.

FROM WHAT ARRIVED TO WHAT CAN BE SHOWN, IN TWO NAMED SUBTRACTIONS Bar length is drawn to scale. Every figure belongs to this invented household and to one year. EVERYTHING THAT ARRIVED FROM OUTSIDE THE HOUSEHOLD Rs 5,74,780/- less Rs 96,000/- of counter takings, real money that no document outside the household records WHAT IS LEFT ONCE THE UNDOCUMENTED MONEY COMES OUT Rs 4,78,780/- less Rs 1,180/- of interest, recorded by the bank but arriving on no repeating date WHAT CARRIES SOMEBODY ELSE'S DOCUMENT AND REPEATS ON A DATE Rs 4,77,600/- THE SECOND SUBTRACTION IS Rs 1,180/- Drawn to the same scale as the bars above, it is about one pixel wide. That is the honest size of a year of interest on the buffer beside a year of pay, and it is still income. Neither subtraction is a judgement about the money. Each one names a document that does not exist.
The household's Rs 5,74,780/- narrows to Rs 4,77,600/- through two named subtractions rather than through any disagreement, and the figure that survives is exactly the take-home salary.

The distance between what a household calls its income and what an outsider will work with is a series of named subtractions, and every one of them is about a missing document rather than about missing money. Naming the subtractions helps in a room where it can otherwise feel like being doubted. The gap is not an accusation. The gap is a list, and every item on the list has a reason attached to it that both sides can look at. Whatever an outsider then does with the figure left over, and how a decision is reached on the strength of it, is covered separately.

Why is a household's own idea of its income usually wider than the idea somebody outside the household works with?

Try it out

Seven of the twelve months came in below Rs 47,800/-. What was the longest run of consecutive months below that line?

The failure: one number asked to describe twelve different months

Writing the household's income as Rs 47,800/- a month is arithmetically defensible. The figure is take-home pay of Rs 39,800/- plus average counter takings of Rs 8,000/-, and the twelve months do add to Rs 5,73,600/-. Seven of the twelve months came in below that same figure. The seven are April, June, July, August, January, February and March, and they were short of the line by Rs 24,400/- between them, exactly matching the Rs 24,400/- by which the other five stood above it.

Look at where the short months sit rather than only at how many there are. The short months arrive in runs. June, July and August are three in a row below the line, and January, February and March are another three in a row. Three in a row is the longest unbroken stretch the year contains. The last three are also the quietest months at the counter, Rs 3,600/-, Rs 2,400/- and Rs 1,600/-, the end of a fall that begins in December. December itself is the month people expect to find in that run and it is not there: the counter took Rs 9,400/- in December, money in was Rs 49,200/-, and the month sat above the line even while the third school term of Rs 9,600/- fell due. A run of falling takings and a run of months below a planning line are two different things, and only one of them is on the household's own timetable.

The fault is not optimism and it is not carelessness with arithmetic; it is that a single number was asked to describe twelve months that were never alike, and no single number can do that. Nobody in this household made a mistake. The average was computed correctly, the year did end ahead, and the counter did take Rs 96,000/-. The figure could not say when. The limitation belongs to averages rather than to anybody who used one.

TWELVE MONTHS AGAINST ONE PLANNING LINE OF Rs 47,800/- Each bar is how far that month of money in stood above or below the line, in rupees. The five months above the line stand Rs 24,400/- above it in total. The seven months below the line sit Rs 24,400/- below it in total. That balance is what an average is. It is not what a month is. 4,400 800 6,200 11,600 1,400 800 2,400 3,200 1,600 4,400 5,600 6,400 Rs 47,800/- above below Apr May Jun Jul Aug Sep Oct Nov Dec Jan Feb Mar THREE IN A ROW BELOW THREE IN A ROW BELOW Bars above the line are months that reached Rs 47,800/-. Bars below it are months that did not. December is above the line.
Seven of the twelve months came in below Rs 47,800/-, and the longest unbroken run below the line is three months, which happens twice, in June to August and again in January to March.
Where this guide stops. How tax deducted at source is worked out, what a provident fund is, and what happens to the money once it has been deducted are covered separately. Deduction rates, tax rates and thresholds are set by statute and by scheme rules, and they change from time to time. Decisions made outside the household on the strength of an income figure are covered separately. Holding money after it lands, protecting it and putting it towards anything are covered separately. Whether any income is enough is a judgement for the household itself.
