Finance Calculators

EMI, SIP, GST and other finance calculators.

Finance calculators estimate loan EMIs, SIP returns, GST amounts, currency conversions, percentage changes and sale discounts — the quick maths you need before signing a loan, filing an invoice or comparing prices.

All calculations run on your device. Enter real figures privately; nothing is stored or sent to a server.

Common tasks

  • Compare monthly EMI at different interest rates or tenures
  • Work out GST inclusive vs exclusive pricing
  • Convert USD, INR, EUR and other major currencies
  • Calculate the final price after a percentage discount
