1. 047What is contribution margin, and why is it not the same as gross margin?Unit economics and costingCorephone / first roundCost accountingCorporate FP&A

   Say this

   Contribution margin is revenue less all variable costs, wherever they sit in the P&L. Gross margin is revenue less cost of goods sold, which is an accounting classification that mixes fixed and variable. They differ because factory overhead is in gross margin and variable selling cost is not.

   Then walk it

   1. Gross margin follows the statutory P&L: cost of goods sold includes direct material, direct labour and absorbed factory overhead, some of which is fixed regardless of volume.
   2. Contribution follows behaviour, not classification. So it excludes factory rent and supervisor salaries, and it includes freight to customer, sales commission, marketplace fees and payment gateway charges, which usually sit in operating expenses.
   3. The gap can be large. An e-commerce brand might report a 55 percent gross margin and have a 22 percent contribution margin once shipping, commission, returns and customer acquisition are counted. The second number is the one that decides whether growth makes money.
   4. You use contribution for any incremental decision: pricing, one-off orders, whether to keep a product line, breakeven, and how much a discount actually costs you. You use gross margin for external comparison, because that is what peers disclose.
   5. The hard part in practice is classifying semi-variable costs. Power, maintenance and a warehouse team are partly fixed and partly volume-driven, and the honest treatment is a high-low or regression split rather than a guess.
   6. One caution: contribution margin only holds over a relevant range. Cross a capacity step and a supposedly fixed cost jumps, so decisions built on contribution have to be checked against capacity.

   Where candidates lose it

   Treating the two as synonyms, or defining contribution as revenue less cost of goods sold. The distinguishing insight is that variable selling costs sit below gross margin, so gross margin overstates the true unit economics of a digital or direct-to-consumer business.

2. 048Walk me through a break-even calculation and tell me where it breaks down.Unit economics and costingCoretechnicalCost accountingCorporate FP&A

   Say this

   Fixed costs divided by contribution per unit gives break-even volume. Divide by the contribution margin ratio instead and you get break-even revenue. It breaks down because fixed costs are only fixed over a range and the product mix never stays constant.

   Then walk it

   1. The arithmetic: fixed costs of 4 crore and contribution of 400 rupees per unit means you break even at 1 lakh units. If contribution is 40 percent of price, break-even revenue is 10 crore.
   2. Add a target profit on top of fixed costs to get the volume needed for a plan, which is how I would actually use it in a budget conversation.
   3. Margin of safety is the useful companion: actual volume less break-even volume as a percentage of actual. At 1.3 lakh units against a 1 lakh break-even, you have 23 percent of headroom, and that is the number a CFO wants in a downturn.
   4. First breakdown: step-fixed costs. Add a second shift or a new warehouse and fixed cost jumps, so there are multiple break-even points, not one.
   5. Second: mix. With ten products at different contribution margins, break-even depends on the blend you sell, so the single-product formula is a simplification that can be badly wrong.
   6. Third: it assumes price is independent of volume, which is exactly false in the situation where you most want to use it, namely deciding whether to cut price to fill capacity. So I treat break-even as a framing device and do the real work with a contribution-by-product model.

   Where candidates lose it

   Dividing fixed cost by gross margin or by price instead of contribution per unit. Also, presenting break-even as if fixed costs are genuinely fixed. Naming step costs and mix is what turns a formula into analysis.

   Expect next

   • What is the margin of safety and why does it matter?
   • How would you handle break-even with ten products?
   • Where would a step-fixed cost sit in a services business?
3. 049How are margins and operating leverage at the company, and what does high operating leverage mean for you as an analyst?Unit economics and costingIntermediatetechnicalMoody'sCorporate Finance · New York · 2018

   Say this

   Operating leverage is the share of the cost base that is fixed, and it decides how violently profit moves when revenue moves. High operating leverage means a small revenue change becomes a large EBIT change, in both directions.

   Then walk it

   1. The measure is the degree of operating leverage: percentage change in EBIT over percentage change in revenue. It equals contribution divided by EBIT, so a business with 40 crore of contribution and 10 crore of EBIT has a DOL of four.
   2. So at a DOL of four, revenue up 10 percent gives EBIT up 40 percent. Revenue down 10 percent gives EBIT down 40 percent. That symmetry is the whole point, and analysts routinely model the upside and forget the downside.
   3. High leverage sits with cement, steel, hotels, telecom, airlines, exhibition and any asset-heavy business. Low leverage sits with distribution, trading and staffing, where cost follows revenue almost one for one.
   4. For a credit view, operating leverage and financial leverage compound. A cement company at four times operating leverage and three times net debt to EBITDA converts a mild demand slowdown into a covenant breach. I would never assess one without the other.
   5. What I actually do with it: build the cost base into fixed and variable, compute the revenue decline that takes EBIT to zero, and compare it against the worst historical peak-to-trough volume decline in that industry. That is a far better risk statement than a margin forecast.
   6. The caveat is that fixed costs are only fixed for a while. Management cuts discretionary spend in a downturn, so realised downside leverage is usually a bit better than the arithmetic, and realised upside leverage a bit worse because of wage and maintenance catch-up.

   Where candidates lose it

   Defining operating leverage as 'high fixed costs' and stopping. Give the contribution-over-EBIT measure and a number, then insist on the downside case. Interviewers at rating agencies are specifically testing whether you compound operating with financial leverage.

   Expect next

   • What revenue decline takes this company's EBIT to zero?
   • How does operating leverage interact with financial leverage?
   • Which sector in India has the highest operating leverage?

4. 050Why does reported profit differ between absorption costing and marginal costing?Unit economics and costingHardtechnicalCost accountingBig Four

   Say this

   Because of fixed overhead sitting in inventory. Absorption costing puts fixed factory overhead into the cost of each unit, so any unit you make but do not sell carries some of this year's fixed cost into next year. Marginal costing charges all fixed overhead to the period.

   Then walk it

   1. The rule: if production exceeds sales, absorption profit is higher, because fixed overhead is deferred in closing inventory. If sales exceed production, absorption profit is lower, because you are releasing last period's deferred overhead.
   2. A number makes it clear. Fixed overhead of 10 lakh, production 10,000 units, so 100 rupees absorbed per unit. Sell 8,000 and 2 lakh of fixed cost sits in inventory rather than the P&L, so absorption profit is 2 lakh higher than marginal.
   3. Which means absorption costing lets you increase reported profit by producing for stock. That is a genuine perverse incentive and it is one reason plant managers on profit targets build inventory.
   4. Ind AS 2 and IAS 2 require absorption costing for statutory inventory valuation, so you have no choice externally. Marginal costing is a management technique for decisions.
   5. So the practical split: absorption for the statutory accounts, contribution and marginal costing for every decision about pricing, product mix, make or buy and special orders. Using absorbed full cost for a pricing decision leads you to reject profitable business.
   6. The other trap is over- or under-absorption. If actual volume differs from the volume used to set the overhead rate, you get a variance that has nothing to do with efficiency, and it needs to be explained separately or it pollutes the margin story.

   Where candidates lose it

   Saying the difference is 'just presentation'. It is a real profit difference driven by inventory movement, and the direction is determined by production versus sales. Getting the direction backwards is the standard failure here.

   Expect next

   • Which gives a truer picture of performance?
   • How does over-absorption arise and where does it go?
   • Which would you use to decide whether to drop a product line?
