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.
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.
