FD Calculator – Fixed Deposit Maturity Calculator
Quick Answer
A fixed deposit (FD) maturity amount equals P x (1 + r/n)^(n x t), where P is the principal, r is the annual interest rate, n is compounding frequency per year, and t is years. Per Reserve Bank of India norms, most Indian banks compound FD interest quarterly.

How Fixed Deposits Work
A Fixed Deposit (FD) is a financial instrument offered by banks and NBFCs where you deposit a lump sum for a fixed tenure at a predetermined interest rate, earning guaranteed returns with no market risk. According to the Reserve Bank of India (RBI), fixed deposits remain the most popular savings instrument in India, with commercial bank term deposits exceeding ₹200 lakh crore as of 2024.
This calculator helps you estimate the maturity value before committing funds. By entering the principal amount, annual interest rate, tenure, and compounding frequency, you can compare FD schemes from different banks on an equal basis. Unlike market-linked instruments such as SIP investments, FDs provide capital protection and predictable returns, making them suitable for risk-averse investors, senior citizens, and those with short-term savings goals.
The FD Interest Formula
Fixed deposits earn compound interest using the standard compound interest formula:
A = P x (1 + r/n)^(n x t)
Where P is the principal amount, r is the annual interest rate (as a decimal), n is the compounding frequency per year, and t is the tenure in years. Most Indian banks use quarterly compounding (n=4) by default. For example, ₹1,00,000 deposited at 7% for 5 years with quarterly compounding yields: A = ₹1,00,000 x (1 + 0.07/4)^(4x5) = ₹1,41,478. The total interest earned is ₹41,478.
Key Terms You Should Know
- Compounding Frequency: How often interest is calculated and added to the principal. Options include monthly (12x/year), quarterly (4x/year), half-yearly (2x/year), and annually (1x/year). Higher frequency yields slightly better returns.
- TDS (Tax Deducted at Source): Banks deduct 10% TDS on FD interest exceeding ₹40,000/year (₹50,000 for senior citizens). Submit Form 15G/15H to avoid TDS if your total income is below the taxable threshold.
- Premature Withdrawal: Breaking an FD before maturity usually incurs a penalty of 0.5-1% reduction in the applicable interest rate, per RBI guidelines.
- Cumulative vs. Non-Cumulative FD: Cumulative FDs reinvest interest until maturity (higher returns). Non-cumulative FDs pay interest monthly/quarterly (regular income stream).
- Tax-Saving FD: A 5-year FD that qualifies for Section 80C deduction up to ₹1.5 lakh/year, with a mandatory 5-year lock-in period.
FD Rates Comparison by Major Banks (2025)
FD rates vary significantly across banks. The table below shows approximate general rates for 1-year and 5-year tenures as of early 2025 (rates change frequently -- verify with the bank before investing).
| Bank | 1-Year Rate | 5-Year Rate | Senior Citizen Bonus |
|---|---|---|---|
| SBI | 6.80% | 6.50% | +0.50% |
| HDFC Bank | 6.60% | 7.00% | +0.50% |
| ICICI Bank | 6.70% | 7.00% | +0.50% |
| Post Office TD | 6.90% | 7.50% | N/A |
| Small Finance Banks | 7.50-8.50% | 7.50-8.00% | +0.25-0.75% |
Practical Examples
Example 1 -- Standard 5-year FD: Priya deposits ₹5,00,000 at 7.0% for 5 years with quarterly compounding. Maturity amount: ₹5,00,000 x (1 + 0.07/4)^20 = ₹7,07,393. Interest earned: ₹2,07,393. If she is in the 20% tax slab, her post-tax interest is approximately ₹1,65,914.
Example 2 -- Short-term parking: Rajesh has ₹2,00,000 from a bonus and wants to park it for 6 months at 6.5%. With quarterly compounding: A = ₹2,00,000 x (1 + 0.065/4)^2 = ₹2,06,551. Interest: ₹6,551 for 6 months. This beats a savings account (typically 2.5-3.5%) by approximately ₹3,000.
Example 3 -- Senior citizen with monthly income: Mrs. Sharma, 65, deposits ₹10,00,000 in a non-cumulative FD at 7.5% (including senior citizen bonus). She receives monthly interest of approximately ₹6,250 before TDS. Her TDS threshold is ₹50,000/year. Since annual interest is ₹75,000, TDS of ₹2,500 will be deducted. She can use our Income Tax Calculator to determine her net tax liability.
Tips for Maximizing FD Returns
- Compare rates across banks: Small finance banks and post office term deposits often offer 0.5-1.5% higher rates than large banks. Always check current rates before committing.
- Use FD laddering: Instead of one large FD, split your deposit across multiple tenures (1, 2, 3, 5 years). This provides periodic liquidity while capturing higher long-term rates.
- Claim the senior citizen bonus: Most banks offer 0.25-0.75% extra interest for depositors aged 60+. Some banks offer super-senior (80+) rates of up to 1% additional.
- Submit Form 15G/15H: If your total income is below the taxable threshold, submit these forms to your bank to avoid unnecessary TDS on interest income.
- Consider tax-saving FDs: A 5-year tax-saving FD provides Section 80C deduction up to ₹1.5 lakh/year, effectively boosting your after-tax return by your marginal tax rate.
- Compare with PPF and RD: Use our PPF Calculator and RD Calculator to compare FD returns with other fixed-income instruments.
FD Tax Rules for 2025-2026
FD interest is fully taxable as per your income tax slab under "Income from Other Sources." Under the new tax regime (FY 2025-26), the basic exemption is ₹3 lakh with no deduction for interest income. Under the old regime, the Section 80TTA deduction of ₹10,000 on savings account interest does not apply to FD interest, but Section 80TTB allows senior citizens to deduct up to ₹50,000 of interest income from all deposits combined. The Income Tax Department requires banks to report all FD interest on Form 26AS, so ensure your tax returns reflect this income accurately.
Frequently Asked Questions
What is a Fixed Deposit and how does it work?
A Fixed Deposit (FD) is a savings instrument offered by banks and NBFCs where you deposit a lump sum for a predetermined tenure at a fixed interest rate. Unlike savings accounts, the rate is locked for the entire period. Interest is compounded (typically quarterly in India) and paid at maturity for cumulative FDs or periodically for non-cumulative FDs. FDs are covered by DICGC insurance up to ₹5 lakh per depositor per bank. They are among the safest investments available, offering guaranteed returns with no exposure to market volatility, making them ideal for conservative investors and short-term goals.
How is FD interest calculated and what compounding frequency is best?
FD interest uses the compound interest formula: A = P x (1 + r/n)^(n x t). Most Indian banks compound quarterly (n=4), though some offer monthly compounding. Monthly compounding yields slightly higher returns: on ₹10 lakh at 7% for 5 years, monthly compounding produces ₹14,17,625 versus ₹14,14,778 with quarterly -- a difference of ₹2,847. While more frequent compounding is marginally better, the rate itself matters far more. Always compare the effective annual yield rather than nominal rates when evaluating FDs across banks.
Is FD interest taxable in India?
Yes, FD interest is fully taxable as income under "Income from Other Sources" at your applicable slab rate. Banks deduct TDS at 10% when annual interest exceeds ₹40,000 (₹50,000 for senior citizens aged 60+). If you do not provide your PAN, TDS is deducted at 20%. To avoid unnecessary TDS when your total income is below the taxable threshold, submit Form 15G (for individuals under 60) or Form 15H (for senior citizens) to your bank at the start of each financial year. Senior citizens can also claim a deduction of up to ₹50,000 under Section 80TTB of the Income Tax Act.
What happens if I break my FD before maturity?
Premature withdrawal of an FD is allowed by most banks, but it typically incurs a penalty of 0.5-1% reduction in the applicable interest rate. For example, if you break a 5-year FD after 2 years, the bank applies the 2-year rate minus the penalty. Some banks offer "sweep-in" FDs that automatically break partial amounts when your savings account balance falls below a threshold, minimizing penalty impact. Tax-saving FDs (5-year lock-in) cannot be broken prematurely under any circumstances. To maintain liquidity, consider FD laddering -- splitting your deposit into multiple FDs with staggered maturity dates.
How does FD compare to PPF, RD, and savings accounts?
FDs offer 6.5-8.5% interest (varies by bank and tenure) with flexible lock-in periods from 7 days to 10 years. PPF offers 7.1% (government-set, tax-free) but has a 15-year lock-in with limited partial withdrawal. Recurring Deposits offer similar rates as FDs but accept monthly installments rather than a lump sum. Savings accounts offer only 2.5-3.5% at major banks. FDs are best for lump-sum investment with a defined horizon, while PPF suits long-term tax-free wealth building and RDs suit monthly savers.
