Reporting a calculator problem
Please include the full calculator page address, the inputs entered, the result shown and the result you expected. Do not send account numbers, medical records, payment details or other sensitive personal information. Most calculators run entirely in your browser, so we cannot see or retrieve values you previously entered.
Privacy requests
For a question about cookies, advertising or personal information, mention “Super Simple Calculator privacy” in your message. Our Privacy & Cookies Policy explains what technical information may be processed and the choices available to you.
Response and corrections
We aim to assess clear, reproducible calculator errors promptly. A correction may require checking a formula or an authoritative source, so a complete report is much easier to investigate than a general description. Editorial suggestions are considered under our editorial policy.
