Marketplace Fee Calculator
The price tag is not what you earn. Every marketplace takes its cut in a different stack of percentage fees, fixed fees and processing charges — usually calculated in a spreadsheet, or not at all.
Fee schedules are the published US rates as of late 2026 — marketplaces change them often, so confirm the live schedule for your category before pricing a whole catalog on this.
The price tag is not what you earn. Every marketplace takes its cut in a different stack of percentage fees, fixed fees and processing charges — usually calculated in a spreadsheet, or not at all. Pick the marketplace, enter the sale, and see every fee line, what you actually keep, your margin, and the break-even price below which the sale loses money.
The Marketplace Fee Calculator on GrabConvert does its one job with no ceremony: What you actually keep on Etsy, eBay, Poshmark, Mercari & Amazon. No account, no watermark, nothing kept — it runs, you download the result, and that is the whole transaction.

FAQ
Why does the fee base include shipping?
Because on Etsy, eBay, Mercari and Amazon the percentage fees are charged on the total the buyer pays — price plus the shipping you charge. Sellers who price from the item price alone systematically under-count their fees.
Is this really free?
Yes — completely. A short ad before processing keeps every tool free; no account, subscription or credits are ever required.
What happens to my file?
It is processed in a temporary folder and deleted the moment your download finishes. We never store, view or share uploads.
Do I need to install anything?
No. Everything runs in your browser session against our servers — any phone, tablet or computer works.
