Why this exists
Marketplace selling decisions are easier when the fee basis, estimated payout, and product costs can be inspected separately. MarketCalcs is built to make that reasoning visible instead of reducing it to one opaque percentage.
Our product standard
- Show the inputs, fee lines, and result definitions clearly.
- Label an estimate as an estimate when evidence is incomplete.
- Block unsupported combinations instead of silently guessing.
- Keep the core calculation usable without an account.
Independence
MarketCalcs is an independent service. It is not affiliated with, endorsed by, or operated by eBay. eBay transaction details and account policies determine the actual fees charged to a seller.
Current coverage
The first calculator is intentionally narrow: eBay US, No Store or Starter Store, most categories, one item, and buyer payment at or below $7,500. The application enforces this scope at calculation time and does not claim universal fee coverage.
