Formula & How It Works
Compound Interest Formula:
A = P × (1 + r/n)^(n×t)
Where:
A = Maturity Amount (Final Value)
P = Principal (Initial Amount)
r = Annual Interest Rate (as decimal)
n = Compounding Frequency per Year
t = Time in Years
Interest Earned = A - P
The calculator applies the compound interest formula above. For example, if you invest ₹1,00,000 at 6% annual interest for 12 months with quarterly compounding (n=4), the maturity amount would be approximately ₹1,06,136. This means you earn ₹6,136 in interest.

What is a Fixed Deposit?
A Fixed Deposit (FD) is a financial product offered by banks and financial institutions where you deposit a lump sum amount for a fixed period at a predetermined interest rate. Your money grows through compound interest, and you receive the full amount plus earned interest on maturity. FDs are one of the safest investment options in India, backed by deposit insurance up to ₹5 lakh per depositor per bank.
Fixed deposits are ideal for conservative investors who want guaranteed returns without market risk. The interest rate and tenure are fixed at the time of opening, so you know exactly how much you'll earn. Different banks offer varying interest rates, so comparing them using this calculator helps you make better investment decisions.
FDs can be opened for durations ranging from 7 days to 10 years. Interest can be paid at maturity or at regular intervals (monthly, quarterly, half-yearly). You can also choose to reinvest the interest, which increases your returns through compounding. Some banks allow premature withdrawal with a penalty if your financial needs change.
