What is a fixed deposit?
A fixed deposit (FD) is a bank or NBFC product where you lock a lump sum for a fixed term at a guaranteed interest rate. Interest is usually compounded periodically — monthly, quarterly, half-yearly or yearly — and paid together with your principal at maturity.
How this FD calculator works
Enter the principal, the annual interest rate, the term and how often interest is compounded. The calculator applies the compound-interest formula to show your maturity amount and the total interest you will earn over the deposit period.
How to use the FD Calculator
- Enter the deposit amount. Type the principal you want to lock in.
- Add the interest rate. Use the annual rate your bank offers.
- Set the term. Enter the deposit period in years.
- Pick the compounding frequency. Choose how often interest is added, then read your maturity value.
Frequently asked questions
What compounding frequency should I pick?
Most Indian banks compound FD interest quarterly, which is the default here; check your deposit certificate to be sure.
Does more frequent compounding help?
Slightly. For the same rate, more frequent compounding produces a marginally higher maturity value.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate; this calculator shows the pre-tax figure.
