How to Use the Fixed Deposit Calculator
Enter the amount you plan to deposit, the annual interest rate offered by your bank, the tenure of the deposit, and how often interest compounds. The calculator instantly shows the maturity amount and total interest earned.
Formula
A = P × (1 + r/n)n × t
P = principal, r = annual interest rate, n = compounding frequency per year, t = tenure in years
P = principal, r = annual interest rate, n = compounding frequency per year, t = tenure in years
Example
Depositing ₹100,000 for 5 years at 7% annual interest, compounded quarterly (the standard for most Indian bank FDs), matures to roughly ₹141,478 — earning about ₹41,478 in interest over the tenure.
FAQs
- Why is quarterly compounding the default? Most Indian banks compound fixed deposit interest quarterly, so it's used as the default — switch to monthly, half-yearly, or annual if your bank's scheme differs.
- Are taxes deducted from the maturity amount? This calculator shows pre-tax figures. Banks may deduct TDS on interest earned above the annual exemption threshold, and interest income is taxable per your income slab.
- Does the rate stay fixed for the whole tenure? The calculator assumes a fixed rate throughout, which matches how bank FDs normally work — the rate is locked in when you open the deposit.
Common Use Cases
- Comparing maturity values across different banks or compounding frequencies before investing.
- Planning a lump-sum investment goal for a future expense.
- Understanding how compounding frequency affects the final interest earned.
