How to Use the Break-Even Revenue Calculator

Calculate break-even units/revenue and revenue needed for target monthly profit based on your unit economics.

Before You Start

  • Use current fixed-cost totals and realistic variable cost per sale.
  • Set a target monthly profit that matches your planning horizon.

Step-by-Step

  1. Enter pricing and cost inputs: Add fixed costs, price per sale, variable cost, and optional target profit.
  2. Add current sales volume: Include current unit volume to compare against break-even requirement.
  3. Calculate break-even outputs: Review break-even units, break-even revenue, and target-profit revenue.
  4. Use sensitivity scenarios: Compare price/cost/fixed-cost scenarios to choose the fastest path to safety.

How to Read the Output

  • Contribution margin per sale is the core driver of break-even speed.
  • Margin of safety indicates how far current revenue sits above or below break-even.

Common Mistakes to Avoid

  • Treating variable costs as fixed and distorting contribution margin.
  • Planning around one scenario without testing price and cost sensitivity.
