How this calculator works
The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
Contribution margin basis
Break-even revenue uses the contribution margin available after the variable costs included in the calculator, not a generic gross-margin percentage unless that is actually the cost basis entered.
Revenue needed to cover fixed costs
Divide fixed costs by the positive contribution-margin rate to calculate the revenue level where total contribution equals the fixed costs entered. If contribution is zero or negative, there is no finite positive break-even revenue under that cost structure.
