1. 041If margin goes down by 5 percent, how much would you need to increase revenue to hold profit flat?Investment judgementIntermediatetechnicalSycamore PartnersConsumer and Retail · New York · 2026

   Say this

   It depends on whether the 5 percent is relative or absolute, so I would clarify first. If margin falls from 20 percent to 15 percent, an absolute 5 point drop, you need revenue to rise by a third to hold profit flat.

   Then walk it

   1. Take revenue of 100 and a 20 percent margin, so profit is 20.
   2. If margin falls 5 percentage points to 15 percent, you need revenue R where 0.15R equals 20, so R is 133. That is a 33 percent increase.
   3. If the 5 percent is relative, so margin goes from 20 percent to 19 percent, you need 0.19R equals 20, so R is 105. About a 5 percent increase.
   4. The general rule for the relative case: a relative margin decline of x percent requires roughly x percent more revenue, since profit is margin times revenue.
   5. The absolute case is far more punishing, and the lower the starting margin the worse it gets. At a 5 percent starting margin, losing 2 points means you need to grow revenue by two thirds.
   6. The commercial insight: this is why low-margin businesses cannot discount their way out of trouble. Volume almost never compensates for the price given up, which is the maths behind resisting a price war.

   Where candidates lose it

   Not clarifying absolute versus relative. The two answers differ by a factor of six and the interviewer is watching whether you ask. Then do the arithmetic with round numbers out loud.

   Expect next

   • What if the starting margin were 5 percent?
   • So would you ever discount to defend share?
   • How does operating leverage change your answer?
