How to Build a Household Money System, One Step at a Time
A household money system is eight steps done once and then maintained. List every account. Write every fixed outgoing with its date. Write every variable line with its range. Build the twelve-month calendar of yearly items. Fix a review date. Write each goal as a number with a date. Set the buffer as a number of months. Record where every paper is.
Here is what sits underneath that list. Not one of the eight steps is difficult, and anybody who has ever looked at a bank statement can do any of them on any evening. Households almost never do them in an order, one after the next, until the last one is finished. The order is not a matter of taste. Step five adds up what steps two, three and four produced, so it cannot be done until they exist. Step seven divides a goal against what step five found, so it cannot be done until step five has produced a figure. Run the eight steps out of order and the later ones quietly read from numbers that were never finished.
Each of the eight steps asks for one thing, gets written down in one form, and has one place its raw material comes from. The whole build takes about three hours and leaves the household holding four sheets, and one skipped step changes every number that comes after it. The eight steps build the systemA set of steps a household runs once and then keeps up to date on a fixed day of the month.. Every decision inside it stays with the household.
What is a household money system, and what is it made of?
A household money system is four sheets of paper and one day of the month. Four sheets and one day are the whole of it, and the word system does more work than four sheets deserve. The eight steps produce an accounts sheet, an outgoings sheet, a twelve-month calendar and a goals sheet, with a date written at the top of the first one. Nothing else is added, nothing is bought, no application is filled in and no product appears anywhere in it. The eight steps produce four sheets and one date, and a household can tell from those five things exactly when the setting up is finished.
The eight steps run in the order below. Read them once before starting anything. The shape of the whole is easier to hold than eight separate instructions, and the order is where most of the value sits.
What is step one, and why does it come first?
Step one is a list of every account the household holds. One line each, and each line carries four things: the name of the account, where it is held, the balance today, and the purpose the account actually serves. Include the accounts nobody thinks about, including the one opened years ago for a reason that has passed, the deposit nobody has looked at, and any account in a second person's name that the household treats as part of the same pot.
Step one comes first because every step after it either reads a figure off an account or writes a figure into one. A household that builds the rest of the system around three accounts when there are four has a system that is wrong from its first line, and the wrongness does not announce itself later. The Bhosale household wrote four lines: the salary account at Rs 6,760/-, the buffer savings account at Rs 30,180/-, the recurring deposit at Rs 40,000/- of deposits paid in, and a public provident fund account at Rs 84,000/-, coming to Rs 1,60,940/- held across the four on the day the sheet was written. The recurring deposit line carries a note that the interest is credited at maturity and is therefore not in that figure.
What is the first step of a household money system, and why does it come first?
What is step two, and what goes on every fixed line?
Step two is one line for every fixed outgoingAn amount that leaves the household on the same date every month and at the same size, such as a rent payment or a loan instalment., and a fixed line is not finished until it carries three things: what it is, how much it is, and which day of the month it leaves. The day is not decoration on the line. The day is half of the line, and a step-two sheet with amounts and no dates is a step-two sheet that is not done. Total the column at the foot.
The Bhosale household wrote four fixed lines. Rent of Rs 14,000/- on the 5th. The two-wheeler loan instalment of Rs 3,150/- on the 7th. Society maintenance of Rs 1,200/- on the 10th. Mobile and broadband of Rs 1,050/- on the 12th. The column totals Rs 19,400/-. Written with their dates, the four lines show that all of the Bhosale household's fixed outgoings leave inside the eight days between the 5th and the 12th. No total on its own could have carried that fact.
A household writes a fixed line down with its amount but leaves the date column blank. Is step two done for that line?
What is step three, and where do the ranges come from?
Step three is one line for every outgoing that happens every month but never at the same amount. Each line carries the name, the average of the last twelve months, and a rangeThe lowest month and the highest month a variable line reached across the last twelve months, written as two numbers rather than one.. The range is the lowest month and the highest month across the last twelve. Three numbers, not one. The raw material is the same twelve statements step four will need, so many households read them once and fill both sheets in the same pass.
The Bhosale household wrote six variable lines averaging Rs 18,520/- a month. Groceries and vegetables averaged Rs 11,200/- and ran from Rs 9,800/- in February to Rs 13,400/- in October. Electricity averaged Rs 1,850/- and ran from Rs 900/- in December to Rs 3,400/- in May. The other four lines, cooking gas at Rs 830/-, fuel and travel at Rs 2,400/-, medicines at Rs 640/- and eating out and outings at Rs 1,600/-, were written at one figure each rather than as a range. Two of the Bhosale household's six variable lines were written with a range and four were written as a single figure, and the sheet says which is which rather than pretending all six are equally solid.
What is step four, and how is the twelve-month calendar built?
Step four is a sheet ruled into twelve boxes, one for each month of the year. Take a year of statements and read them one month at a time, oldest first. Every payment that does not already appear on the step-two sheet or the step-three sheet gets written into the box for the month it actually landed in, with its name beside its amount. Total each box. Total the twelve boxes. The twelve-box total, divided by twelve, is the figure step five will use. The yearly calendarTwelve boxes, one per month, with every once-a-year or few-times-a-year payment written into the month it actually lands in. is the only one of the eight steps whose raw material is a year of the past rather than something the household can look at today.
The Bhosale household found fifteen such items totalling Rs 96,000/- across the year. School fees in three terms of Rs 9,600/- in April, August and December. A life cover premium of Rs 9,600/- in July. A health cover premium of Rs 14,400/- in September. Two-wheeler insurance and servicing of Rs 4,900/- in January. Festival spending of Rs 9,900/- in October and Rs 6,600/- in November. Travel to Ashok Bhosale's mother of Rs 3,600/- in May and again in December. Clothes and footwear in April, October and March. Repairs, replacements and gifts in June and February. The heaviest box on the Bhosale household's calendar is September at Rs 14,400/-, the lightest is March at Rs 1,800/-, and no month at all carries the yearly average of Rs 8,000/-.
Where does a household find the items that belong in the twelve-month calendar?
What is step five, and what does the total get set against?
Step five is one line of arithmetic and it is the shortest step of the eight. Take the step-two total, add the step-three monthly average, add the step-four yearly total divided by twelve, and write the result. Then write what comes in each month beside it, on the same line, and write the difference underneath. The difference between the two is the surplusWhat is actually left in a month once all three kinds of outgoing have been counted, rather than only the ones that show up every month.. Where income itself changes from month to month, write the twelve-month average and note beside it that no single month equals it.
For the Bhosale household, Rs 19,400/- of fixed lines plus Rs 18,520/- of variable lines plus Rs 8,000/- of yearly items divided across the months comes to Rs 45,920/- a month leaving. Income is Rs 39,800/- of take-home salary plus Rs 8,000/- a month on average from Ashok Bhosale's tailoring counter, a total of Rs 47,800/-. The difference is Rs 1,880/- a month. Across the whole year the same arithmetic reads Rs 5,73,600/- in, Rs 5,51,040/- out and Rs 22,560/- left. The counter takings the Bhosale household experiences as spare money, at Rs 8,000/- a month on average, are exactly the same size as the once-a-year items that never reached a monthly plan.
What is step six, and where does the review date go?
Step six takes about two minutes. One day of the month is chosen and written at the top of the accounts sheet, in the largest handwriting on the sheet. Writing that one day down is the whole step. A review dateA fixed day of the month, chosen in advance, on which the household reads its own sheets rather than deciding when to get round to it. is a day, not a plan and not an intention, and it is written on paper rather than kept in somebody's head. Households that keep the sheet on a wall, inside a cupboard door or in the front of a folder pick the day that suits where the sheet lives.
The Bhosale household chose the 2nd of every month, the day after the salary is credited on the 1st. The date is written at the top of the accounts sheet and again on the inside of the kitchen cupboard door. Step six is placed before the goals rather than after them. Everything written from this point on is only worth writing if something brings the household back to look at it.
Why is the review date fixed at step six rather than added at the end once everything else is written?
What is step seven, and how is each goal written down?
Step seven gives every goal three numbers on one line: the amount, the date it is needed by, and the amount divided by the number of months between now and then. Divide straight, with no growth of any kind assumed, and write on the sheet that no growth has been assumed. Then total the monthly column and set it against the figure step five produced. Write both numbers and the difference between them, whatever the difference turns out to be.
The Bhosale household wrote three goals. An admission deposit of Rs 60,000/- needed in 26 months, or Rs 2,308/- a month. Rebuilding the buffer to Rs 1,13,760/- from the Rs 30,180/- held, a gap of Rs 83,580/- over 36 months, or Rs 2,322/- a month. Ira Bhosale's higher education at Rs 8,00,000/- in today's money in 132 months, or Rs 6,061/- a month. The three together ask for Rs 10,691/- a month. Step five had produced Rs 1,880/-. The Bhosale household's three goals ask for Rs 10,691/- a month against the Rs 1,880/- step five found, and writing that Rs 8,811/- difference down is the step, not solving it.
What is step eight, and what does the buffer get stated as?
Step eight has two halves and both are short. The first half writes the buffer targetThe buffer written as a number of months of committed outgoings rather than as a fixed amount, so it moves when the outgoings move. as a number of months of committed outgoings, then the amount that number of months comes to, then the amount actually held, then the difference. Committed outgoings are the step-two total plus the step-three total. Written as months rather than as an amount, the line stays true when rent changes. The months stay the same and the amount recalculates itself at the next review.
The second half is a list of where every paper sits. One line per document, and each line carries the document's name and the physical place it sits in. Identity papers, the loan agreement, the policy documents, the tax papers, the deposit passbook, the rent agreement. Where a document exists in two places, both places go on the line.
The Bhosale household set the buffer at three months of committed outgoings. Committed outgoings are Rs 19,400/- plus Rs 18,520/-, a total of Rs 37,920/-, so three months is Rs 1,13,760/-. The buffer holds Rs 30,180/-, so the difference is Rs 83,580/-, and that is the figure that became the second goal on the step-seven sheet. The papers list ran to eleven lines, and one of them records that the health cover policy document is at Ashok Bhosale's mother's home, 340 km away.
Why does step eight ask for the buffer as a number of months rather than as an amount?
How long does the whole eight-step setup take a household from a standing start?
What does the whole thing cost in time?
About three hours to build and about a quarter of an hour a month to keep, on the Bhosale household's own count of two evenings at the kitchen table. Step four took two hours and five minutes of that three hours. A year of statements has to be read a month at a time, and nothing makes that faster. The other seven steps came to fifty-five minutes between them, and step six took two minutes. Building the system once costs about three hours, and keeping it for a whole year costs the same three hours again, a quarter of an hour at a time.
Twelve reviews of fifteen minutes each is three hours across a year. The whole of the first year comes to about six hours including the build. Every year after that is three hours. The building never happens twice. Most households stop before starting because they believe the build is a weekend rather than two evenings, and the split between three hours to build and a quarter of an hour a month to keep is worth seeing first.
What keeps the system running once it is built?
The review date, and nothing else. All eight steps are one-off work apart from a single line of maintenanceThe small recurring work that keeps a set of sheets true after they are built, as against the one-off work of building them. on the day of the month the household chose. On that day the balances on the accounts sheet get rewritten, the box for the month just gone on the calendar gets a tick or a correction, and anything that changed on a fixed line gets changed. Nothing is rebuilt. Nothing is recalculated from scratch. The four sheets are the same four sheets a year later, with newer numbers on them.
Unusually, whether the setting up is finished has a definite answer, and the answer is worth using. Finished does not depend on how organised the household feels or on whether the sheets look neat. Eight written checks decide whether a household money system is built, and any check still unanswered is simply the next job rather than a verdict on anything.
The four sheets exist and every check is answered. What is the only thing that keeps the system true from here?
What does the finished system look like on paper?
Four sheets, and they fit in the front of one folder. The accounts sheet carries the review date at the top of it. The outgoings sheet carries steps two and three on one sheet, with the two totals at the foot. The calendar sheet carries twelve boxes. The goals sheet carries steps seven and eight, with the buffer target written in months. Nothing else is part of it, and there is no ninth sheet waiting.
What did the eight steps produce for one household?
The Bhosale household ran the eight steps across two evenings at the kitchen table. Meghna Bhosale read the statements and Ashok Bhosale wrote. Every figure below is what the household wrote down across those two evenings.
| Step | What was written | What it produced |
|---|---|---|
| One | Four accounts, each with a balance and a use | Rs 1,60,940/- held |
| Two | Four fixed lines, each with its own date | Rs 19,400/- a month |
| Three | Six variable lines, two of them with a range | Rs 18,520/- a month |
| Four | Fifteen items placed across twelve boxes | Rs 96,000/- a year |
| Five | The three totals added, set against what comes in | Rs 1,880/- a month left |
| Six | One day of the month, at the top of sheet one | the 2nd |
| Seven | Three goals, each divided straight with no growth assumed | Rs 10,691/- a month asked |
| Eight | Three months of committed outgoings, and eleven papers placed | Rs 1,13,760/- target |
| All eight | Two evenings, about three hours, four sheets and one date | Rs 8,811/- a month short of the goals |
Read the last row plainly. The Bhosale household finished the eight steps holding a written statement that its three goals ask for Rs 8,811/- a month more than the month currently leaves. The Rs 8,811/- line is the output of the system, not a failure of it, and the system offers no view about what should happen next. The eight steps changed one thing: the number is now on a sheet with a date beside it instead of being nowhere at all.
A household runs the other seven steps and skips the fourth. How far out is the surplus it reads?
Count the steps in, one at a time, and watch a comfortable month turn into the month that actually happened.
Nothing about the Bhosale household changes as the control moves. The salary is the same salary, the counter earns the same, the rent is the same rent and not one line is added or removed. The only thing that moves is how many of the eight steps the household has actually done. The row of eight squares shows which ones are counted, and at the first setting the fourth square is the empty one. The rail shows what the household believes leaves each month. The strip below it shows what each of the twelve months actually did on that same counting. The panel opens with all eight steps counted, the Bhosale household's own position.
Because a finding that lives only inside a moving panel is invisible to anybody who cannot move it, here are the readings in plain text. With step four skipped, the Bhosale household counts Rs 37,920/- leaving each month against Rs 47,800/- coming in, and reads an apparent surplus of Rs 9,880/- a month with every month of the year looking identical and comfortable. With step four done, it counts Rs 45,920/- leaving, reads a true surplus of Rs 1,880/- a month, and five of the twelve months turn out to have finished below zero: April, July, August, September and December. The whole distance between a comfortable Rs 9,880/- and a true Rs 1,880/- is the Rs 8,000/- a month of once-a-year items, and every figure other than that one is identical in both readings.
The mistake: running seven of the eight steps and leaving out the fourth
Step four is the one that gets left out, and it gets left out for a reason that is not laziness. Step four is the only step whose raw material is a year of the past. Every other step can be done from something the household can look at today: an app, a passbook, a rent agreement, a bill. Step four needs twelve statements read one at a time, and it is the step that gets started on a Sunday evening and abandoned around August.
A household that runs steps one, two, three and five and stops there ends up holding a sheet that says Rs 37,920/- leaves each month against Rs 47,800/- coming in, leaving a comfortable Rs 9,880/-. Every single figure on that sheet is correct. The rent is right, the groceries are right, the salary is right, and the arithmetic is right. The sheet is still out by Rs 8,000/- a month, the Rs 96,000/- of once-a-year items divided by twelve, and the reading of Rs 9,880/- is more than five times the true Rs 1,880/-.
The skipped step costs far more than the two hours it saves. Steps five, seven and eight are then all built on a number that is more than five times too large. The goals get costed against Rs 9,880/-. The buffer target gets set against Rs 9,880/-. The error does not stay quiet either. Five months of that year finished below zero in a year the household believed was easy. A household in that position has not been careless. The household has done seven eighths of the job correctly and been let down by the one step that no app, no statement and no memory can produce for it.
Where does a system like this actually get used?
Outside the household, three sets of people ask for parts of it and none of them ask nicely in advance. A lender assessing an application asks what comes in, what leaves and what is already committed. Steps two, three and five produced exactly that, and a household holding those three sheets answers in one sitting rather than across three weeks of digging. An insurer settling a claim asks for a policy document and a policy number. The second half of step eight is that line, and having it written rather than not is usually measured in weeks rather than in rupees. A school, a hospital admissions desk or a landlord asks a household to produce a figure or a paper at short notice, and the whole of step eight exists so that the answer is a place rather than a search.
Inside the household, the use is smaller and more frequent. On the review date somebody looks at four sheets for a quarter of an hour and knows the position without asking anybody. The month with the heaviest calendar box is visible three months before it arrives rather than on the day it lands. The Bhosale household's health cover premium of Rs 14,400/- in September is written in a box that anybody in the household can see in June, and that early sight is the entire practical difference the calendar makes. Nothing in that changes what the household can afford. The calendar changes only when the household finds out.
