How We Can Help

To help our team route your message and respond faster, please indicate which category your inquiry falls under:

• Bug Reports & Technical Issues — Did a calculator fail to load? Is a layout broken on your device? Did you spot a rounding error in a financial output? Please include the URL of the tool, the browser you are using, and a description of the issue.
• Formula Accuracy — If you believe a calculator is producing incorrect results or you have identified a discrepancy between our output and an authoritative source, please include the calculator name, your inputs, the result you received, and the source you believe shows a different result.
• Translation & Localisation — If you notice an awkward phrasing or incorrect term in our Spanish, French, German, or Portuguese versions, please let us know so we can correct the translation immediately.
• New Calculator Requests — Is there a specific health, finance, or math calculator you need but cannot find a reliable version of online? Pitch it to us — we are always looking for new Verified Formulas to digitize and add to our library.
• Business & Advertising Partnerships — For ad network representatives, affiliate programme managers, or technical partnership inquiries, please include details of your proposal in your initial message.
• Privacy & Data Rights — For GDPR, CCPA, or third-party cookie inquiries, please review our Privacy Policy first, then contact us with any remaining questions.
