Free seller tool

Know your safe floor before a repricer does.

Estimate the minimum selling price needed to cover product cost, fulfillment, fixed fees, marketplace commission and your target margin.

Enter costs for one order. Taxes, storage, advertising, returns and category-specific charges are not included unless you add them under other per-order costs.

Estimated safe floor$30.96

At this price, estimated profit is $3.72 and the target margin is 12%.

How the calculation works

Standard mode: safe floor = fixed costs ÷ (1 − marketplace fee rate − target margin rate). Walmart mode: floor = (per-order costs + desired fixed profit) ÷ (1 − referral fee rate). Treat either result as a planning estimate and verify every input before automating prices. The calculator runs entirely in your browser and does not send or store your inputs.
