What this calculator does
Estimates the maturity value and interest earned on a Fixed Deposit (FD) for a chosen principal, rate, compounding frequency, and tenure. It gives an easy view of total return to plan savings goals.
Designed for Indian FDs but useful anywhere you want to model compound interest with common payout frequencies.
Who should use this calculator
- Savers planning term deposits
- Investors comparing bank FD rates
- Anyone evaluating short- or medium-term savings goals
How this calculator works
It uses the chosen principal, annual interest rate, compounding frequency (annual, quarterly, monthly, etc.), and tenure to calculate how interest accumulates each period and the final maturity amount. The logic simulates interest being added back to the principal at each compounding interval and totals the result—no formulas or external lookups are displayed.
How to interpret the results
Maturity shows the total amount returned at the end of the tenure. Interest earned equals maturity minus principal. Compare different compounding frequencies to see how more frequent compounding slightly increases returns.
Example
If you invest ₹1,00,000 at 6.5% annually compounded monthly for 3 years, the calculator shows an estimated maturity value and the interest earned over that period. Use the example to judge short-term goals.

- Use the compounding selector to match your bank's payout schedule.
- Tenure accepts decimals (e.g., 1.5 years) for flexibility.
- No external APIs or data sources; everything calculates on-page.
FAQs
What compounding frequency should I pick?
Choose how often your bank compounds interest: annual, semi-annual, quarterly, or monthly. More frequent compounding slightly increases maturity value.
Does this include taxes or TDS?
No. This calculator shows gross maturity and interest. Tax Deducted at Source (TDS) or income tax on interest is not applied here.
Can I use it for reinvestment FDs?
Yes. Reinvestment FDs pay interest back into the principal each period, matching the compounding approach used here.
What if the rate changes mid-tenure?
Most FDs keep a fixed rate for the booked tenure. If your bank changes the rate, recompute with the updated numbers.
