Contact CalPaisa

Send a question, share feedback on a calculator, or report a result that looks wrong. Every message helps make the calculators better.

What you can write to us about

  • General questions — how a calculator works or what an input means.
  • Calculator feedback — missing inputs, clearer wording, or a calculator you'd like added.
  • Calculation error reports — a result that doesn't match your own working or an official source.
  • Content corrections — outdated rates, tax rules or explanations.
  • Business / partnership enquiries — collaboration or content proposals.

Messages are reviewed as time allows. CalPaisa is a small project, so replies are not guaranteed and response times can vary.

Contact form

For calculation issues, include the calculator name, the inputs you used, the result shown and the result you expected.

Please don't include passwords, bank details, card numbers or other sensitive personal information in your message.

Found an incorrect calculation?

Because CalPaisa publishes financial calculations, accuracy reports are the most valuable feedback we receive. Please report anything that looks off, even if you're unsure.

To help us reproduce and fix it quickly, include:

  • The calculator name or page URL
  • The exact inputs you used (amount, rate, tenure, options selected)
  • The result CalPaisa displayed
  • The result you expected, and the source or method you compared it against, if available

You can also double-check the method first: every calculator page shows its formula and a worked example. Start from all calculators.
