Mercari Profit Calculator
What is left after fees, postage and packaging.
Marketplace fee models change often, and several platforms in this set have altered theirs outright in recent years. These defaults are a starting point — your own seller terms are the authority.
Profit per sale
$24.47
48% margin on $51.00
Fees take 12.7% of the order and costs take 39.3%, leaving 48%. A selling fee plus separate payment processing. Mercari's fee model has changed direction more than once — including a period with no seller fee at all — so confirm the current structure before pricing against it.
How the Mercari Profit Calculator works
Resale profit on Mercari lives or dies on postage. The platform's discounted labels help, but a heavy item sold cheaply can lose money after fees and shipping even when the sale looks like a good margin on the item alone.
Not financial advice. Marketplace fees change, and they vary by country, plan and seller status. Every rate here is an editable default, not a quoted price — check the platform's current fee schedule before you price a product against it. This is not tax or business advice.
Frequently asked questions
How do I calculate profit on Mercari?
Sale price plus any shipping the buyer paid, less the selling fee, less payment processing, less what you paid for the item, less actual postage and packaging.
Should I offer free shipping?
It converts better but the cost lands entirely on you. For light items it is usually worth it; for anything heavy, charging shipping separately protects the margin even at some cost to conversion.
What does packaging really cost?
Usually 40 cents to a pound once mailers, tape and filler are counted. It is small per order and it is the line resellers most often forget entirely.
How do returns work?
Mercari holds funds until the buyer confirms or a window passes, and returns are permitted for items not as described. Accurate photos and honest condition notes are the cheapest return prevention available.
