Calculate FD Maturity
What is a Fixed Deposit?
A Fixed Deposit (FD) is a deposit product offered by banks, NBFCs, and post offices that locks in your money for a fixed term at a guaranteed interest rate. It is one of the most popular low-risk savings options in India because the principal is secure (insured up to ₹5 lakh by DICGC for bank FDs) and the return is contractually fixed at the time of booking.
FDs are ideal for emergency funds, short-term goals (6 months to 3 years), or conservative investors who prefer assured returns over market-linked products. Most banks compound interest quarterly; cumulative FDs reinvest interest until maturity, while non-cumulative FDs pay periodic interest (monthly, quarterly, or annually).
Key Features at a Glance
- Tenure: 7 days to 10 years.
- Interest: Typically 6%–7.75% for general; senior citizens get 0.25–0.75% extra.
- Compounding: Quarterly (standard) — bank pays interest on interest.
- Safety: Insured by DICGC up to ₹5 lakh per depositor per bank.
- Liquidity: Premature withdrawal allowed with a 0.5–1% penalty (except 5-year tax-saver FDs).
- Taxation: Interest fully taxable; TDS at 10% above ₹40,000 (₹50,000 for senior citizens).
- Tax-saver FD: 5-year lock-in, qualifies for ₹1.5 lakh deduction under Section 80C.
How the Calculation Works
Compound (quarterly) formula: A = P × (1 + r/4)4t
Simple interest formula: A = P × (1 + r × t)
Where A = maturity, P = principal, r = annual rate, t = tenure in years.
Worked example: A ₹1,00,000 FD at 6% p.a. for 1 year with quarterly compounding matures to ~₹1,06,136 — earning ₹6,136 in interest, slightly more than the ₹6,000 you'd get with simple interest.
