FD Calculator
Work out the maturity value and interest on a fixed deposit, with monthly, quarterly, half-yearly or yearly compounding.
About this calculator
A fixed deposit (FD) locks a lump sum with a bank or NBFC for a set tenure at a fixed interest rate. This free FD calculator shows the maturity value and the total interest you will earn, with a choice of compounding frequency so it matches how your bank actually credits interest.
How it works
The maturity uses compound interest: M = P × (1 + r/n)^(n×t) — deposit P, annual rate r, n compounding periods per year and tenure t in years. Quarterly compounding (n = 4) is the most common in India.
Worked example
Deposit ₹1,00,000 for 5 years at 7% p.a. compounded quarterly and it grows to about ₹1,41,478 — roughly ₹41,478 of interest.

Why use this FD calculator
Maturity and interest upfront
Enter the deposit, rate and tenure and see the exact maturity value and interest earned with the bank's usual quarterly compounding.

Flip between 1, 3 and 5-year terms to see how a longer lock-in changes your return before you book the FD.
Plan around TDS
Knowing the interest in advance helps you anticipate the TDS banks deduct once interest crosses the annual threshold.
