About the Savings Interest Calculator
Savings Interest Calculator computes the maturity value of any fixed deposit, recurring deposit or savings account using the standard compound-interest formula A = P × (1 + r/n)nt. Choose how often interest is compounded — annually, half-yearly, quarterly, monthly or daily — to match what your bank actually does. Optionally add a fixed monthly contribution and the tool treats it as a separate compounding annuity stacked on top of the base principal. The output shows the maturity value, the total amount contributed and the interest earned, so you can see at a glance how much your money has grown by.
How to use

Pro tip
Quarterly compounding is the default for most Indian FDs. Banks occasionally advertise an "effective annual yield" — use that figure as the annual rate to skip the math.

Frequently asked questions
Are tax rates up to date?
Yes — the Income Tax calculator uses the FY 2024-25 slabs announced in the Union Budget. GST and surcharge bands reflect the latest CBIC notifications.
Does this replace a CA or financial adviser?
No. These calculators are decision helpers for routine questions. Anything involving capital gains, NRI status or trust income still needs a qualified professional.
