Contact Us
Have a question, found an error in a calculation, or have an idea for a new tool? We'd like to hear from you.
Email: [YOUR-EMAIL@yourdomain.com] — replace this with your real contact address before publishing.
We read every message and aim to respond within a few business days. Since this site doesn't use accounts or logins, email is the only way to reach us — please include enough detail (which calculator, what you entered, what you expected) if you're reporting a possible error, so we can look into it quickly.
For general feedback or tool suggestions, feel free to write in as well — this site is actively growing, and reader suggestions are genuinely one of the ways new calculators get added.
