Fixed Deposit (FD) Calculator
Use our free FD Calculator to estimate the returns on your fixed deposits.
What is FD Calculator?
An FD calculator helps you estimate how much a fixed deposit will grow over time based on the principal amount, rate of interest, and tenure. It is useful for comparing safe, predictable returns across banks and deposit durations.
Financial calculators are useful because they turn assumptions into numbers you can compare. Instead of guessing, you can test different values for amount, time horizon, expected rate, and goal requirements to understand how the final result changes before you commit.
How this calculator works
The maturity value for a fixed deposit depends on the deposit amount, annual interest rate, compounding frequency, and tenure. The formula is generally based on compound interest, where the accumulated amount grows each compounding period and the interest is added back to the principal.
Worked example
If you invest ₹2,00,000 for 5 years at 7% interest compounded quarterly, the maturity value will be higher than simple interest because interest is earned on the accumulated balance as the tenure progresses. This helps you compare bank deposits and choose the best option for parking short-term or medium-term savings.
Most common mistakes people make
- Using the wrong compounding frequency when comparing bank FD offers.
- Forgetting that FD interest is taxable in many cases, which reduces the real return.
- Ignoring premature withdrawal penalties and liquidity constraints.
- Comparing rates without checking whether the quoted rate is for cumulative or non-cumulative FDs.
- Treating the projected maturity value as guaranteed without considering tax and reinvestment assumptions.
