Break-Even Price Calculator
Break-even Price Calculator adds total cost and fees, then divides by quantity to find the average unit price that produces zero modeled profit. It is a cost-coverage threshold, not a recommended selling price. Taxes, payment percentages, returns, discounts, unsold inventory, variable shipping, and target profit can all raise the practical price required.

Add total cost and fees, then divide by the number of units.
Formula: Break-even price = (total cost + fees) ÷ quantity
Break-even price allocates modeled costs across units
At the calculated unit price, selling every entered unit produces revenue equal to entered cost plus fees. Profit is zero under those assumptions. Fixed and variable costs must be aggregated consistently.
How it works
Enter the complete cost pool, known fees, and the number of units expected to carry those costs. Add a profit requirement or percentage-based selling fee in a separate model.
Key concepts
Quantity assumption drives allocation
Higher quantity spreads fixed cost more thinly, but only if those units are actually sold.
Break-even is zero profit
A business normally needs additional margin for profit, uncertainty, and future costs.
When to use it
- Allocate a known batch cost across units.
- Check a minimum price before target profit.
- Compare break-even effects of quantity changes.
When not to use it
- Do not assume every produced unit will sell.
- Do not omit percentage fees that grow with selling price.
- Do not treat break-even as sufficient margin for risk or operations.
Worked examples
Batch cost
- Input
Cost 900; fees 100; quantity 100- Expected output
10 per unit
One thousand of modeled cost divided by one hundred units.
Fewer sellable units
- Input
Same costs; 80 units- Expected output
12.50 per unit
Shrinkage or unsold inventory raises the required average.
Zero quantity
- Input
Quantity 0- Expected output
Undefined
Costs cannot be allocated across no units.
Common mistakes
Using produced rather than sellable units
Waste and unsold stock make the denominator too large. Correction: Use a realistic sales quantity.
Forgetting percentage transaction fees
A fixed fee input may not capture price-dependent costs. Correction: Solve with a fuller margin model.
Calling break-even profitable
Revenue only equals modeled cost. Correction: Add target profit and risk allowance.
Best practices
- Document every included cost and fee.
- Use conservative sellable quantity.
- Model target margin separately.

Frequently asked questions
Does break-even price include profit?
No. It covers entered cost and fees only.
Which quantity should I use?
Use the number of units realistically expected to sell and absorb the costs.
Can quantity be zero?
No. Division by zero is undefined.
What about percentage marketplace fees?
They require a price-dependent equation rather than a simple fixed-fee input.
