How to use Break-Even Units
Estimate contribution and whole units needed to cover a period’s fixed costs.
- List fixed costs for a single, explicit period.
- Identify costs that increase with each sale.
- Check that price exceeds variable cost, then round the target to sellable units.
Formula & calculation method
Contribution per unit = selling price − variable cost. Exact break-even units = fixed costs ÷ contribution. Whole-unit target is rounded up.

These labels describe the calculation’s base units. Supported measurements can switch through the header’s region settings; follow the current workspace labels. Prefilled values are examples.
- Fixed costs for your chosen period
- Enter a plain number with a decimal point if needed. The workspace shows an illustrative value, not a recommendation.
- Selling price per unit
- Enter a plain number with a decimal point if needed. The workspace shows an illustrative value, not a recommendation.
- Variable cost per unit
- Include the variable costs applicable to each sale. All amounts use one currency.
A quick example
With fixed costs of 1,000, a unit price of 25 and variable costs of 10, contribution is 15. The exact point is 66.6667 units, so 67 whole units cover those modeled costs.
Assumptions, edge cases & limits
- Use a consistent time period and complete cost assumptions. Taxes, returns, multiple product mixes and changing costs can change the result. Break-even is not cash flow.
- Selling price must exceed variable cost. Fixed and variable costs must refer to the same planned activity and period.
Questions about Break-Even Units
What if variable cost is greater than selling price?
There is no finite positive-volume break-even point in this simple model because each sale contributes zero or a negative amount toward fixed costs. Check the price and full variable cost assumptions.
Does reaching break-even mean the business has enough cash?
No. Break-even compares modeled revenue and costs for a period. Payment timing, inventory, financing and taxes can create a different cash-flow position.
Are my files or inputs uploaded?
Calculation and file processing run in your browser without a processing upload. Downloads go to your device. Choosing a next-step transfer creates a temporary local copy for that workflow. Region preferences are stored separately from tool inputs. See our privacy details.
Can I use this tool for free?
Yes. No signup, subscription or payment is required to use the tool or download its output. File tools have device and size limits; a smaller batch may work better on a phone.
