The starting values are an editable example. These inputs are calculated in your browser and are not submitted to the server.
YOUR PLANNING ESTIMATE
- Contribution per sale
- $40.00
- Whole sales to break even
- 25
- Revenue at break-even volume
- $2,500.00
Money inputs are rounded to the nearest cent. This simple model assumes price, variable cost and fixed costs stay unchanged across the sales volume. Include taxes and other expenses in your inputs where appropriate.
Formula and scope
Contribution per sale = price − variable cost. Break-even sales = fixed costs ÷ positive contribution, rounded up to the next whole sale. Revenue at that volume = whole sales × price.

Worked example: a $100 sale with $60 variable cost contributes $40. Covering $1,000 of fixed costs takes 25 sales and $2,500 of revenue. Include all relevant expenses in your own model.
