Questions, corrections, or suggestions for a calculator you wish existed? We read everything.
Write to us at [email protected]. We aim to reply within a few business days.
Especially welcome
- Accuracy reports — if any result looks wrong, include the inputs you used and we'll investigate immediately.
- Tool requests — tell us what you needed to calculate and couldn't; the most-requested tools get built first.
- Content corrections — tax rates, category thresholds, and conventions change; pointers to current sources help everyone.
Please note we can't provide personal financial, medical, or legal advice — our terms explain why the calculators are educational tools rather than professional guidance.
