Contact us

Found a bug in a calculator? Have an idea for a tool you'd actually use? We read every message.

Email us

The fastest way to reach us is email:

[email protected]

We typically reply within a few business days. Please don't send sensitive personal or financial information by email — our calculators are designed so you never need to share real account details with us, and the same applies here.

What to include in a bug report

  • Which tool you were using (the page URL helps)
  • What numbers you entered
  • What answer you expected vs. what you got
  • Your browser and device (e.g., "Safari on iPhone")

Suggesting a new tool

The best suggestions come with a real calculation you keep doing by hand. Tell us the inputs you'd type in and the answer you'd want back — that's usually enough for us to know whether it's a fit.
