Every rate, fee rule and threshold in the calculators is taken from the official page below: the marketplace’s own fee page, the law, or the tax authority. We do not use blogs or other calculators as a source of numbers. Each link was opened and compared with the rule it supports on the date shown. The same list appears on each calculator page under “How this tool works”. Fees change often; the changelog records each change, and we re-read every page monthly.

These are calculators, not tax or legal advice. If a link breaks or a page changes, write to support@resalepocket.com.
