Every rate has a source and a date
Each calculator shows the official page it was read from and the day we last checked it. If a platform changes a fee, the change log records old value, new value and effective date.
Tested against the platforms’ own examples
Where a platform publishes worked examples of its fees, the calculator must reproduce them to the cent before a change ships. The test results are public on the methodology page.
Independent and ungated
Not owned by any marketplace, payment company or carrier. No sign-up, no email gate. Questions and corrections: contact.
