1. 046If margin goes down by 5 percent, how much would you need to increase revenue to balance it out?Unit economics and costingIntermediatetechnicalSycamore PartnersConsumer and Retail · New York · 2026

   Say this

   It depends entirely on whether the 5 points came off price or off cost, and I would say that before calculating. If the margin loss is a price cut, you need a very large volume increase, because the extra units only earn the reduced margin.

   Then walk it

   1. Set it up cleanly. Take 100 of revenue at a 20 percent contribution margin, so 20 of profit. Cut price by 5 percent: revenue per unit falls to 95, cost per unit stays at 80, so contribution per unit drops from 20 to 15.
   2. To rebuild 20 of profit at 15 per unit you need 1.33 units for every one you sold, so volume has to rise 33 percent. That is the number, and it is why discounting is so dangerous in a low-margin business.
   3. The general formula: required volume increase equals old contribution margin divided by new contribution margin, minus one. At a 40 percent margin, the same 5-point price cut only needs about a 14 percent volume lift. Low-margin businesses cannot discount their way anywhere.
   4. If instead margin fell 5 points because of input cost inflation, the arithmetic on volume is similar but the answer is different: volume does not fix a cost problem profitably, price or procurement does.
   5. And if 'margin down 5 percent' means relative, from 20 percent to 19, the answer is roughly a 5.3 percent revenue increase. I would ask which the interviewer means rather than guess, because the two readings differ by a factor of six.
   6. Then the real-world caveat: 33 percent more volume usually needs more capacity, more working capital and more service cost, so the true breakeven volume is higher than the arithmetic. Discounting almost never pays for itself.

   Where candidates lose it

   Assuming 'margin down 5 percent' means percentage points and not saying so, or answering 5 percent more revenue because you treated margin as a constant percentage. Clarify the base, then use the contribution ratio, not the gross margin percentage.

   Expect next

   • Now do it at a 40 percent margin.
   • What if the cost base is mostly fixed?
   • Would you ever recommend the price cut anyway?
