Get in Touch
We'd love to hear from you. Whether you have questions, found an error, want to suggest a new calculator, or just want to say hello - drop us a line.
We try to respond within a few business days.
Suggesting a New Calculator
If there's a calculator you wish existed, please tell us! Include as much detail as you can:
- What problem the calculator should solve
- What inputs and outputs you'd expect
- Any reference formula or methodology you trust
The most-requested calculators move to the top of our build queue.
Reporting an Error
Calculations should be reproducible. If a calculator gives a result that doesn't match what you expect, send us:
- The calculator (link or name)
- The exact inputs you entered
- What you expected vs. what we showed
We treat correctness issues as priority and usually fix them within 24-48 hours.
