🏦 FD Calculator (Fixed Deposit)

About this FD Calculator (Fixed Deposit)

A fixed deposit (FD) locks a lump sum with a bank for a set period at a guaranteed rate. This FD calculator applies compound interest at the frequency you choose — quarterly is what most banks use — and shows the maturity value and the total interest earned, so you can compare tenures and rates before visiting the bank.

How to use it

1. Enter the lump sum you plan to deposit.
2. Enter the yearly interest rate the bank offers.
3. Enter the deposit period in years.
4. Choose how often interest is compounded — quarterly is the usual bank standard — then click Calculate maturity.

Example

A deposit of 500,000 at 12% per year for 5 years, compounded quarterly, matures at about 903,056 — interest of roughly 403,056 on top of your deposit.

Frequently asked questions

Why does compounding frequency change the result?

The more often interest is added to your balance, the sooner that interest starts earning its own interest. Monthly compounding beats yearly compounding at the same headline rate.

Is the bank rate before or after tax?

Banks quote the gross rate, and this calculator uses it as entered. Tax on the interest and any early-withdrawal penalty will reduce what you actually receive.
