FD Calculator

What is an FD Calculator?

An FD calculator is a free online tool that estimates the maturity amount and total interest you'll earn on a fixed deposit. By entering your principal, interest rate, tenure, and compounding frequency (monthly, quarterly, or yearly), the calculator shows you exactly how much your FD will grow to — helping you compare bank rates and pick the right tenure.

A Fixed Deposit is one of India's most trusted savings instruments. You deposit a lump sum for a fixed tenure (7 days to 10 years) at a predetermined interest rate, and the bank guarantees the returns regardless of market conditions. FDs up to ₹5 lakh per bank are insured by DICGC — making them practically risk-free.

Benefits of Fixed Deposits

• Guaranteed Returns: Unlike market-linked investments, FD returns are fixed and guaranteed
• Safe Investment: FDs up to ₹5 lakh per bank are insured by DICGC
• Tax Saving: 5-year tax-saver FDs qualify for Section 80C deduction
• Flexible Tenure: Choose from 7 days to 10 years based on your needs
• Senior Citizen Benefits: Extra 0.25-0.50% interest for senior citizens

FD Maturity Formula

FD maturity is calculated using the compound interest formula:

• M = maturity amount
• P = principal (amount deposited)
• r = annual interest rate (as decimal, e.g. 0.07 for 7%)
• n = compounding frequency per year (1 = yearly, 4 = quarterly, 12 = monthly)
• t = tenure in years

The compounding frequency matters more than people think. A ₹1 lakh FD at 7% for 5 years grows to ₹1,40,255 with yearly compounding, ₹1,41,478 with quarterly compounding, and ₹1,41,763 with monthly compounding — that's an extra ₹1,500 just from compounding more often.

FD Returns: How Much Will You Get?

Real numbers help you visualize. The table below shows what a ₹1,00,000 FD at 7% (quarterly compounding) looks like across different tenures:

Notice how a 10-year FD doubles your principal at 7% — thanks to compounding. The longer the tenure, the more powerful the compounding effect.

FD vs RD vs PPF: Which is Better?

India offers three popular safe-investment options. Each has trade-offs:

Use our RD Calculator and PPF Calculator to compare scenarios for each.

Senior Citizen FD Benefits

Senior citizens (60+) get significantly better FD terms in India:

• +0.25 to 0.50% extra interest: Most banks offer 25-50 basis points more than the regular rate. SBI offers 50 bps extra; HDFC and ICICI offer 50 bps. Some small finance banks offer up to 75 bps extra.
• Super-Senior rate: Many banks offer additional 25 bps for those above 80 years.
• Higher TDS exemption: No TDS on FD interest up to ₹50,000/year (under Section 80TTB), vs ₹40,000 for non-seniors.
• SCSS option: Senior Citizen Savings Scheme offers 8.2% (Q1 FY26) — guaranteed by Government of India, with quarterly interest payouts. Better than most bank FDs for those over 60.

Tax on FD Interest

FD returns are taxable, and many investors miss this — leading to ITR notices. Here's how it works:

• Slab-rate taxation: All FD interest is added to your income and taxed at your marginal rate. For someone in the 30% bracket, ₹1 lakh interest means ₹30,000 in tax.
• TDS at source: Banks deduct 10% TDS if your FD interest exceeds ₹40,000 in a financial year (₹50,000 for senior citizens). To avoid TDS, file Form 15G (non-seniors) or 15H (seniors) if your total income is below the taxable limit.
• 5-year tax-saver FD: The principal up to ₹1.5 lakh qualifies for Section 80C deduction, but the interest is still taxable.
• Reporting in ITR: Always declare FD interest under "Income from Other Sources" — even if TDS was deducted. Failure to do so triggers Section 234B/234C penalties.

How to Choose the Right FD

1. Compare rates across banks: Public banks (SBI, BoB, PNB) usually offer 6.5-7%. Private banks (HDFC, ICICI, Axis) offer 7-7.5%. Small finance banks (SBM, Equitas, Ujjivan) offer 7.5-8.5%. Pick small finance banks for higher returns within DICGC's ₹5 lakh insurance cap.
2. Use FD laddering: Split your money across 1, 2, 3, 5-year FDs. As each matures, reinvest at current rates. This avoids being stuck at a low rate when rates rise.
3. Pick the right compounding: Quarterly compounding is standard. Monthly compounding gives marginally higher returns. Avoid yearly compounding when both options are available.
4. Cumulative vs non-cumulative: Cumulative reinvests interest (better for accumulation goals). Non-cumulative pays interest periodically (better for retirees needing income).
5. Avoid breaking the FD: Premature withdrawal usually costs 0.5-1% in penalty plus loss of accrued interest. If you might need the money, choose shorter tenures.

Frequently Asked Questions

Which bank gives the highest FD interest rate in India?

As of 2026, small finance banks like SBM Bank, Equitas, Ujjivan, and Suryoday SFB lead with 7.5-8.5% rates. Among major banks, IDFC First, RBL, and Bandhan typically offer the highest rates (7.25-7.75%). SBI and HDFC are usually 25-75 bps below.

Is FD interest tax-free?

No. FD interest is fully taxable as "Income from Other Sources" at your marginal slab rate. Only PPF and SGB interest are tax-free.

What is the minimum FD amount?

Most banks require a minimum FD of ₹1,000-₹10,000. Some banks allow FDs starting at ₹100. There is no maximum limit.

Can I break my FD before maturity?

Yes, but with penalty. Most banks charge a 0.5-1% penalty on the applicable interest rate, and you may lose some accrued interest. For example, breaking a 5-year FD after 2 years means you get the 2-year FD rate (which is lower) minus the penalty.

Are FDs in small finance banks safe?

Yes, up to ₹5 lakh per bank — that's the DICGC insurance cover, which applies equally to scheduled commercial banks and small finance banks. To be extra safe, split larger amounts across multiple banks so no single bank holds more than ₹5 lakh of your money.

What is the difference between cumulative and non-cumulative FD?

Cumulative FDs reinvest interest back into the principal — you get the entire amount at maturity. Non-cumulative FDs pay interest monthly, quarterly, or yearly into your bank account — used by retirees for regular income. Cumulative FDs give marginally higher returns due to compounding.

Is a 5-year tax-saver FD better than ELSS?

For most investors, ELSS is better. ELSS has a 3-year lock-in (vs 5 for tax-saver FD), historically delivers 12-15% (vs 6.5-7% for FD), and the gains over ₹1.25 lakh/year are taxed at only 12.5% LTCG. Tax-saver FDs are better only for those who want absolute certainty and zero market exposure.

How is FD interest calculated — simple or compound?

Bank FDs use compound interest — usually compounded quarterly. Some FDs (especially short-tenure ones below 6 months) use simple interest. Always check the term sheet for compounding frequency.

Will RBI rate cuts affect my existing FD?

No — your existing FD's rate is locked for the entire tenure. RBI rate cuts only affect new FDs and FD renewals. This is why locking in FDs at peak rates (before RBI cuts) is a smart strategy.

Should I prefer monthly or quarterly interest payout?

For pure return maximization, neither — go cumulative (interest reinvested). If you need regular income, monthly payout works for routine expenses while quarterly payout typically offers a slightly higher effective rate. Quarterly is standard at most banks.
