A Fixed Deposit (FD) Calculator helps you estimate the maturity amount and total interest earned on your fixed deposit investment. Whether you are investing with a bank or NBFC, this tool gives you a clear picture of your returns before you commit your money.
For Simple Interest: M = P + (P × r × t) / 100
For Compound Interest: M = P × (1 + r/n)^(n×t)
Where P is the principal amount, r is the annual interest rate, t is the time period in years, and n is the number of times interest is compounded per year (monthly = 12, quarterly = 4).
If you invest ₹1,00,000 in an FD at 7% per annum for 3 years with quarterly compounding (n=4), the maturity amount is ₹1,00,000 × (1 + 0.07/4)^(4×3) = approximately ₹1,23,144. Your total interest earned is ₹23,144.
