We'd love to hear from you — especially if you spot a fee that's out of date, want to suggest a calculator, or have a question about how a tool works.

Reporting an incorrect fee

Platform fees change, and we update them as fast as we can. If a rate looks wrong, email us the calculator name and a link to the platform's official pricing page and we'll verify and fix it. Every fee on the site carries a "last verified" date so you can always see how current it is.

Suggesting a calculator

Want a calculator we don't have yet — a specific platform's fees, a comparison, or an AI/API cost estimator? Tell us what you'd use and we'll add it to the roadmap.

We typically reply within a few business days. For how we handle your data, see our privacy policy.
