Multi-Platform Fee Comparison
ONE input, SIX results. Enter your sale amount once and instantly compare what you'd net on every major platform. The only calculator you need to decide where to sell.
How the comparison works
Each platform uses a different fee structure: percentage of sale, fixed per-item, tiered by category, or combinations thereof. This tool applies each platform's standard rate to your input sale amount. Some platforms have category-specific exceptions (e.g., eBay Books, Amazon Jewelry) — check individual calculators for fine-grained numbers.

How to verify this calculator
- Last verified
- — the calculation logic and the automated regression suite were re-run on this date. Fee and rate fields are editable estimates; confirm current values against the official schedule before relying on them.
- Official / methodology source
- This is a platform fee estimator. Its calculation is documented in the project source; we could not confirm the platform's official pricing/help page was reachable on 2026-11-08, so we do not publish an unverified link. Current fees: confirm the live rate on the platform's own pricing or help page before relying on this estimate. We deliberately do not link to a page we could not confirm as reachable on 2026-11-08.
- Method & testing
- All arithmetic runs locally in your browser — no input is uploaded. Calculation behaviour is exercised by the repository's regression suite: 39/39 checks passed (run 2026-11-08). Source & tests on GitHub.
