How to use this FD calculator

1. Principal amount — type the amount you want to deposit (e.g. ₹1,00,000).
2. Interest rate — enter the annual rate your bank is offering (e.g. 7.25%). Check your bank's website for the latest rate.
3. Tenure — choose how long you'll keep the FD (months or years).
4. The calculator immediately shows your maturity amount and the interest you'll earn over that period.

That's it. Adjust any number and the result updates live — so you can compare a 1-year vs 3-year FD in seconds.

Worked example — ₹2 lakh at 7.5% for 3 years

Say you deposit ₹2,00,000 in a bank FD at 7.5% per annum for 3 years, with quarterly compounding (the standard for most Indian banks).

• Principal: ₹2,00,000
• Rate: 7.5% p.a.
• Tenure: 3 years (12 quarters)
• Maturity value: ≈ ₹2,49,136
• Total interest earned: ≈ ₹49,136

So your money grows by nearly ₹49,000 while it sits safely in the bank. Senior citizens earning an extra 0.25–0.50% would see a slightly higher return.

How the FD maturity value is calculated

Indian banks use the compound interest formula with quarterly compounding — interest is added to your principal every three months, and from the next quarter you earn interest on the new (higher) total.

The formula

A = P × (1 + r/n)^(n×t)

Where:
  A = Maturity amount (what you receive at the end)
  P = Principal (amount you deposit)
  r = Annual interest rate as a decimal (e.g. 7.5% → 0.075)
  n = Number of times interest is compounded per year (4 for quarterly)
  t = Tenure in years

Interest Earned = A - P

Snippet example — ₹1,00,000 at 7% for 5 years

P = 1,00,000 | r = 0.07 | n = 4 | t = 5

A = 1,00,000 × (1 + 0.07/4)^(4×5)
  = 1,00,000 × (1.0175)^20
  = 1,00,000 × 1.41478
  ≈ ₹1,41,478

Interest Earned ≈ ₹41,478

Important: This interest of ₹41,478 is fully taxable as per your income tax slab. Banks deduct TDS (Tax Deducted at Source) at 10% if your total FD interest from that bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens aged 60+). If you don't submit your PAN, TDS jumps to 20%.

Quarterly vs annual compounding — does it matter?

Quarterly compounding gives you slightly more than annual. Most Indian banks — including SBI, HDFC Bank, and ICICI Bank — compound quarterly on regular FDs.

Key rules and limits for FY 2025-26 (AY 2026-27)

• TDS threshold: ₹40,000 interest per bank per year (₹50,000 for senior citizens aged 60+). Banks deduct TDS at 10% if your PAN is on file.
• No PAN on file: TDS rate rises to 20% — always link your PAN to your bank account.
• Form 15G / 15H: If your total income is below the taxable limit, submit Form 15G (general) or Form 15H (senior citizens) to your bank to stop TDS deduction.
• Tax on interest: FD interest is added to your total income and taxed at your applicable slab rate — it is not eligible for Section 80C deduction (except 5-year tax-saver FDs).
• 5-year tax-saver FD: Deposits in a scheduled bank FD with a 5-year lock-in qualify for a deduction up to ₹1.5 lakh under Section 80C — but only under the old tax regime. The new default tax regime does not allow this deduction.
• DICGC insurance: Your deposits (principal + interest) are insured up to ₹5 lakh per bank by the Deposit Insurance and Credit Guarantee Corporation. This applies across all your accounts in the same bank.
• Premature withdrawal: Most banks allow early closure but charge a penalty of 0.5–1% on the applicable rate — confirm this with your bank before booking.

For the official TDS rules on bank interest, see incometax.gov.in. For DICGC deposit insurance details, the Reserve Bank of India publishes guidance at rbi.org.in.

Practical tips to get the most from your FD

• Compare rates before booking. A 0.25% difference on ₹5 lakh over 5 years adds up to roughly ₹7,000–8,000 extra — worth five minutes of research.
• Senior citizen rates. If you or a family member is 60+, banks typically offer 0.25–0.50% higher rates. Factor this in when planning a joint or senior FD.
• Laddering FDs. Instead of one large FD, split into multiple FDs with different maturities (e.g. 1 year, 2 years, 3 years). This gives you regular liquidity and lets you reinvest at newer, potentially higher rates.
• Don't ignore the after-tax return. If you're in the 30% slab, a 7.5% FD gives you an effective post-tax return of about 5.25%. Compare this with other options like PPF (tax-free returns) or debt mutual funds before committing large amounts.
• Check the exact compounding method. The calculator uses quarterly compounding, which matches most Indian bank FDs. A few small co-operative banks may compound monthly or annually — verify with your bank.
• Returns shown are indicative. The maturity value assumes the stated rate for the full tenure with no changes. Floating-rate or sweep FDs may differ.
