How FD Maturity Is Calculated

A Fixed Deposit pays compound interest on your principal at a fixed rate for a fixed tenure. Most Indian banks compound FD interest quarterly by default, though some offer monthly, half-yearly, or yearly compounding — the formula is the same, only the compounding frequency (n) changes:

Maturity Value = P × (1 + r/n)n×t

Where P is the principal, r is the annual interest rate, n is the number of compounding periods per year, and t is the tenure in years.

Worked Example

A ₹1,00,000 FD at 7.5% p.a., compounded quarterly, for 3 years: n = 4, t = 3, so Maturity = 1,00,000 × (1 + 0.075/4)12 = ₹1,24,972. Total interest earned = ₹24,972 — about 25% return on principal over 3 years, taxed as per your income slab under "Income from Other Sources."

Frequently Asked Questions

Yes. FD interest is fully taxable at your income tax slab rate under "Income from Other Sources." Banks deduct TDS at 10% if your total FD interest from that bank exceeds ₹40,000/year (₹50,000 for senior citizens) in a financial year — but you still owe tax at your actual slab rate when filing, and can claim the TDS as a credit.
More frequent compounding means interest is calculated and added to your principal more often, so you earn interest-on-interest sooner. A 7.5% FD compounded quarterly yields slightly more than the same rate compounded yearly — the difference grows with a longer tenure and higher rate.
An FD is a lump-sum, one-time deposit. A Recurring Deposit involves fixed monthly contributions, ideal if you're saving progressively rather than depositing a lump sum. Use our SIP Calculator if you're comparing an RD-style monthly plan against market-linked mutual fund investing.
