What it does
Know the exact sales volume where your business stops losing money and starts making a profit. Enter your fixed costs (rent, salaries, subscriptions), variable cost per unit, and selling price per unit. The tool computes the break-even point in units sold and revenue needed, plus your contribution margin per unit.
Add an expected sales figure and you'll also see your margin of safety — how far sales can drop before you hit a loss. Every calculation runs locally. Pair with profit margin when experimenting with prices, or ROI calculator for long-horizon investment math.
How to use it
- Enter total fixed costs per period.
- Enter variable cost per unit.
- Enter selling price per unit.
- Optionally add expected sales to see your margin of safety.
