Enter total contribution C ≥ 0 and fixed costs F ≥ 0 in one monetary unit, then 1–20 sales changes of at least −100%.

Income I = C − F and DOL = C/I. Scenarios keep fixed costs and the contribution-to-sales ratio unchanged: Cₛ = C(1 + s/100), Iₛ = Cₛ − F. Baseline zero income makes DOL and relative income change undefined. A negative baseline gives signed algebraic changes, not a profit-growth multiplier. No sales, cost or profitability forecast is made.

Editing any input clears the result and report.

A QUICK WALKTHROUGH

How to use this tool

  1. Name the monetary unit and enter contribution and fixed costs for one period.
  2. Enter your sales-change scenarios and calculate the signed algebraic results.

Common questions

Does this determine a business plan?

No. It evaluates the entered quantities under the stated model. It does not predict demand or recommend a commercial decision.
