FD Calculator (India)
Estimate maturity amount, interest earned, and payout details for cumulative and non-cumulative fixed deposits.
What is a Fixed Deposit in India?
A fixed deposit (FD) is one of the most popular low-risk investment options in India. You deposit a lump sum with a bank or NBFC for a fixed tenure and earn a predetermined interest rate. At the end of the tenure, you get your principal back along with interest (for cumulative FD), or you receive periodic interest payouts during the tenure (for non-cumulative FD).
This fixed deposit in India calculator helps you quickly estimate your returns so you can compare options before investing.
How this FD calculator works
1) Cumulative FD
In a cumulative FD, interest is added back to principal at each compounding period. That means your money grows with compound interest.
Formula: A = P × (1 + r/n)(n×t)
- P = principal amount
- r = annual interest rate (decimal)
- n = compounding frequency per year
- t = tenure in years
- A = maturity amount
2) Non-cumulative FD
In non-cumulative FD, interest is paid out monthly/quarterly/half-yearly/yearly and not reinvested in the same FD. So you receive regular income, and principal is returned at maturity.
This calculator estimates periodic payout and total interest earned across the tenure.
Sample FD return comparison
| FD Type | Best For | Interest Handling | Typical Outcome |
|---|---|---|---|
| Cumulative | Wealth growth | Reinvested | Higher maturity value due to compounding |
| Non-cumulative | Regular income | Paid out periodically | Steady cash flow, lower final accumulation |
Factors that affect FD returns in India
Interest rate
Even a 0.5% difference in FD rate can significantly change your maturity amount for long tenures. Always compare rates across large banks, small finance banks, and reputed NBFCs.
Tenure selection
Different tenures often have different rates. Sometimes a 444-day or 15-month FD gives better returns than a 1-year FD. Use this calculator to test multiple tenure combinations.
Compounding frequency
Quarterly and monthly compounding can generate better returns than yearly compounding for cumulative deposits, all else equal.
Senior citizen benefits
Most banks in India offer higher FD rates to senior citizens (often +0.25% to +0.75%). If eligible, this can materially improve returns.
Premature withdrawal rules
If you break an FD before maturity, a penalty generally applies and effective interest may reduce. Always check lock-in and breakage conditions before investing.
Taxation of FD interest in India
- FD interest is taxable as "Income from Other Sources".
- Banks may deduct TDS if interest crosses applicable thresholds.
- Your final tax depends on your slab rate, exemptions, and regime choice.
- Tax-saving FDs (5-year lock-in) may qualify for deduction under Section 80C, but interest remains taxable.
Because taxes reduce net return, this calculator provides pre-tax values. You should estimate post-tax returns separately for planning accuracy.
Tips to maximize your FD earnings
- Ladder your deposits (split into multiple maturities) for flexibility and better reinvestment strategy.
- Compare effective annual yield, not just headline interest rate.
- For long goals, consider cumulative FD to benefit from compounding.
- Use non-cumulative FD only if you need predictable periodic income.
- Check deposit insurance limits and spread large amounts across institutions if needed.
Frequently asked questions
Is FD safer than mutual funds?
FDs are generally lower-risk and more predictable, but usually offer lower long-term growth compared to equity mutual funds. Choice depends on your risk appetite and goal horizon.
Which is better: monthly payout or cumulative FD?
If you need income now, choose monthly/quarterly payout. If your goal is wealth accumulation, cumulative FD is usually better due to reinvested interest.
Can I use this calculator for all Indian banks?
Yes. Enter the applicable interest rate, tenure, and frequency offered by your bank to estimate expected returns.
