Break-Even Price
Break-even price is the selling price that exactly covers the costs included in a stated sales scenario.
What is Break-Even Price?
A break-even price is a cost-coverage threshold, not a recommended market price. Its meaning depends on what the calculation includes: product cost alone, all variable order costs, or variable costs plus an allocation of fixed costs at an assumed volume.
This distinction matters when setting a promotional floor. A price can cover the cash costs of shipping one extra order while still failing to fund the business’s monthly overhead. Label the boundary before using the number.
Break-even price = (Dollar costs per unit + Fixed costs ÷ Expected units) ÷ (1 − Fee rate)
This simplified model assumes the percentage fee applies to the selling price excluding tax, all other costs are included once, volume is positive and the fee rate is below 100%. Set allocated fixed costs to zero for a variable-cost-only threshold.
A fee changes the minimum price
An order has $28 of product and other dollar-denominated variable costs. Monthly fixed costs are $4,000, allocated across 1,000 expected orders. A processing fee equals 4% of price. Break-even price is ($28 + $4) ÷ 0.96 = $33.333…. Charging $33.34 reaches cost coverage before rounding differences.
How to interpret it
At that price, the example leaves no intended operating profit after the specified allocation. A buffer for uncertainty or a profit target would require a higher price, but the market’s willingness to pay remains a separate question.
The assumed sales volume is part of the result. If volume falls, fixed costs per order rise. Conversely, a short-term incremental sale may not cause any additional fixed expense, so its relevant threshold may be lower than the fully allocated figure. Neither number should be used without its label.
Fee bases can differ. A payment processor may charge on an amount that includes tax or shipping, and a marketplace may apply several charges. The displayed formula only works as written when those mechanics match its assumptions.
Use the realized price after any discount. A list price above break-even can still generate a below-threshold sale after a coupon. Returns and expected losses also need an explicit treatment if they are material to the scenario.
Common mistakes
Adding a percentage fee to cost
A fee calculated on the final price grows with that price. Dividing by one minus the fee rate captures this relationship; simply adding 4% to cost does not.
Presenting one permanent floor
Costs, sales volume and transaction mechanics change. A break-even price belongs to a defined scenario and date.
