fee per unit = price x fee rate
contribution per unit = price - variable cost - fee
break-even units = fixed cost / contribution per unit
break-even revenue = break-even units x priceHow to use this calculator

- 02Enter selling price and variable cost per unit.

Worked example
$1,200 fixed-cost example
A product has $1,200 fixed cost, $40 price, $18 variable cost, and a 5% fee.
| Contribution per unit | $20.00 |
| Break-even units | 60 |
| Break-even revenue | $2,400.00 |
| Units with 20% buffer | 72 |
What the result means
Break-even is a launch sanity check. It shows how many profitable units are needed before fixed costs are covered.
Decision guidance
How to read the result
The break even point calculator is most useful when the output is tied to a next action. Use it to decide whether the price, fee load, margin, or ad target is strong enough before you publish, promote, or scale the offer.
Check before acting
Do not treat the calculated price as final until you compare it with competitor pricing, customer willingness to pay, and your real fulfillment costs.
Next decision
Use the recommended price as a pricing floor, then test whether the product can support ads, discounts, bundles, or wholesale terms.
Before you use the number
Confirm Fixed cost, Selling price, Variable cost per unit, and Fee rate match the exact sale, product, listing, or campaign you are evaluating.
Use Contribution per unit, Break-even units, and Break-even revenue as a decision threshold, not just a one-off math answer.
Compare the result with your real profit target, cash-flow needs, and customer willingness to pay.
Re-run the calculator when fees, shipping costs, ad costs, materials, labor rates, or marketplace rules change.
Open the related pricing calculators if the next decision involves another fee, platform, price, or ad-spend step.
Pricing estimates become more reliable when labor, packaging, shipping, fees, and overhead are entered as real costs instead of rough guesses.

Methodology
How this calculator is built
The Break-Even Point Calculator is designed as a decision-support calculator, not a generic arithmetic shortcut. It keeps the formula, assumptions, example, source notes, and next-step guidance visible so the number can be checked before it affects a price, listing, or campaign.
Formula-led
This page calculates Contribution per unit, Break-even units, and Break-even revenue from Fixed cost, Selling price, Variable cost per unit, and Fee rate. The formula is shown before the example so you can audit the math instead of trusting a black box.
Decision-first
The result is framed as a planning threshold for break even point calculator, with assumptions, common mistakes, and related next-step calculators on the same page.
Review-triggered
Source-sensitive rates are listed below and should be rechecked after platform fee, payment, shipping, tax, or ad-policy changes.
Use the output as an estimate. Marketplace fees, processor rules, taxes, discounts, refunds, currency conversion, and fulfillment costs can change the final result. See the full calculator methodology for the review process and known limits.
Assumptions
- Fixed costs are the costs that do not change with each unit sold.
- Variable cost should include product cost, labor, packaging, and fulfillment costs tied to each unit.
- The fee is modeled as a percentage of selling price.
Common mistakes
Using revenue instead of contribution per unit.
Leaving seller fees out of variable cost.
Ignoring the buffer needed after break-even.
FAQ
Frequently asked questions
Short answers for the edge cases people usually check before they trust the calculator result.
How do I calculate break-even point?
Divide fixed cost by contribution per unit. Contribution is price minus variable cost and selling fees.
Is break-even the same as profit?
No. Break-even only covers costs. Profit starts after the break-even point.
Should seller fees be included?
Yes. Fees reduce contribution per unit, so they change the break-even count.
