Resale Fee Calculator: Poshmark, Mercari & Depop
Printed 2026-10-27 from billorganizingapp.com/income/calculators/resale-fee/ — an estimate for planning, not financial or tax advice.
Fee percentages differ by platform and change over time — check the current rate before listing.
Keep your budget and bills on track month to month in the free Bill Organizer app.
Every resale app takes a different cut, and the difference between a 6% platform and a 20% platform decides whether an item is worth listing. Type in the fee percentage for wherever you're selling and this calculator gives you the profit, margin, and return on what you paid.
The Costs Beginners Forget
Packaging supplies, the shipping you cover yourself, and the price you originally paid for the item. A $45 sale can quietly become a $20 profit once all three are counted.
Comparing Platforms
Run the same item twice with different fee percentages. Higher-fee platforms often have more buyers, so the real question is whether the extra traffic makes up for the cut. Sourcing cheap matters more than platform choice for most sellers.
Pricing for Profit
Work back from the profit you want per item, not forward from what similar listings show. If a category can't clear your minimum profit after fees, stop sourcing it.
Keep Records
What you paid for inventory is deductible against your resale income, and mileage to thrift stores and the post office counts too. Track it as you go — see the mileage deduction calculator.

Frequently Asked Questions
What fee percentage should I enter?+
Check the current published fee for your platform — they change. Enter the percentage plus any flat per-order charge.
Why is my profit lower than expected?+
Usually shipping you absorbed, supplies, or an item you paid too much for at sourcing. The calculator separates all three.
What is a good profit margin for reselling?+
Many resellers target selling for several times what they paid, but the right number depends on how long items take to sell and how much your time is worth.
