Why you can trust the numbers
From official pages
We read each fee on the platform’s own fee or help page, never from a third-party blog.
Sourced and dated
Every calculator shows its source links and the date the fees were last verified.
Honest about gaps
If a platform does not make a rule clear, we say so on the page instead of guessing.
