Ordinary US one-item sale in USD. The estimate uses Poshmark’s current US commission: $2.95 below $15, or 20% at $15 and above. It does not model bundles, non-US sales, live shipping rates, reverse pricing, returns, consignment, historical fees, automatic promotions, income tax, time, or costs you do not enter.
Proceeds are after modeled commission and seller-funded shipping deductions—not a bank payout or profit. Profit subtracts acquisition and other costs; margin is based on item price. ROI is unavailable when acquisition cost is zero.
Money inputs are limited to $0–$1,000,000 with at most two decimal places; sale price must be positive. These are calculator validation limits, not Poshmark policy. The fee is rounded half-up once to cents as an estimate assumption; the source does not specify a rounding rule.
