Revenue vs total cost
What is a free break-even, and what goes on one?
The break-even calculator tells you exactly how many hours, projects, or units you need to sell to cover all your fixed and variable costs. Below break-even, you're losing money.
Key components
- Fixed costs — rent, subscriptions, insurance (costs that don't change).
- Variable costs — costs that scale with each project.
- Price per unit — what you charge per hour or project.
- Break-even point — the number of units needed to cover all costs.
How to use this tool
- Enter your fixed monthly business expenses (software, internet, insurance).
- Input your variable costs per project.
- Add your target salary or personal draw.
- The calculator will show exactly how much revenue you need to break even.
Why this matters
Without knowing your break-even point, you are flying blind. This number dictates your minimum acceptable rate and protects you from taking on projects that actually cost you money.

Frequently asked questions
Break-even is infinite mathematically—raise price or cut variable costs before scaling.
Monthly recurring obligations you pay even at zero output—rent, core software, insurance baseline.
Yes—the price slider replots revenue vs total cost curves.
Correct—aligns with commission-like structures; reinterpret inputs if you need per-unit materials instead.
How far your actual revenue sits above break-even revenue — a buffer before you slip into loss on the model you entered.
Yes—switch to dollar mode when variable cost is better expressed as a per-unit cash cost instead of a percent of price.
It uses contribution margin to estimate units needed to cover fixed costs plus a profit goal, not just to break even.
It lets you snapshot optimistic, expected, and pessimistic price and cost assumptions side by side for quick planning.
