Free calculator

The discount math,
before you say yes.

Every Q4, discount requests arrive dressed as growth. This calculator runs the arithmetic nobody runs: the breakeven volume for any price move at any margin, and a deal screen that verdicts a specific proposal in margin dollars, not vibes.

What's inside

  • A deal screen: enter the proposed price change, the promised volume, and the revenue affected. The verdict computes in dollars gained or lost
  • The breakeven matrix: gross margin by price change, showing the volume a discount must gain or an increase can afford to lose. Fantasy territory flags itself in red
  • The flow-through table: what 1%, 2%, and 3% of price discipline is worth straight to EBITDA
  • No macros, no lock-in. Opens in Excel and imports cleanly into Google Sheets

How to use it

  1. Enter your annual revenue and blended gross margin. Two cells.
  2. For any live request, fill the four deal-screen inputs. Read the verdict.
  3. Before negotiation season, print the matrix and set an approval floor: concessions past it travel with their breakeven volume attached.
  4. When a discount fails the math, trade something cheaper than price: terms, scope, or a rebate paid after the volume actually arrives.

The background reading: the 1% price increase most owners never take and revenue quality. If you want this running against your numbers properly, start a conversation.
