What is Break-even Calculator?

What are common questions about Break-even Calculator?
What does Break-even Calculator compute?
Break-even units from fixed costs ÷ (price − variable cost per unit), rounded up. It answers how many units you need to sell before you cover fixed costs.
Why do I see an error about selling price?
Price must be greater than variable cost. Otherwise there is no positive contribution margin and break-even is undefined.
Is this financial advice?
No. The tool shows a standard break-even formula for planning. Confirm numbers with your accountant before binding decisions.
Is the browser tool free?
Yes for typical browser use. REST and MCP share 500 free requests per month on one API key.
Does it have a REST API and MCP?
Yes. Call

Units to break even
Returns how many units you must sell before contribution covers fixed costs.
Price vs variable cost check
Warns when selling price is not above variable cost — there is no contribution margin.
Visible inputs
Uses fixed costs, variable cost per unit, and price so you can change one assumption at a time.
API and MCP ready

How do you use Break-even Calculator?
Enter fixed costs
Add rent, salaries, or other costs that do not change with each unit sold.
Enter variable cost and price
Use cost per unit and selling price per unit in the same currency.
Read break-even units
Review the units result, then adjust price or costs and recalculate.
When to use break-even units
Use it when comparing two prices, checking if a promo still covers costs, or estimating minimum volume for a product launch. Keep fixed and variable costs in the same currency and time period.
Privacy
Browser runs stay on the page with the numbers you enter. Do not paste confidential contract figures into shared screenshots. For API or MCP, keep keys out of public repos.
Troubleshooting
If results look wrong, confirm price > variable cost, fixed costs are not zero when they should not be, and units match (per item, not per case). Recalculate after each single change.
