How FD maturity is calculated
Maturity = P × (1 + r/4)^(4 × t)
Most Indian banks compound cumulative fixed deposit interest every quarter. P is the deposit, r is the annual rate as a decimal and t is the tenure in years.
For example, ₹1,00,000 at 7% for 3 years grows to about ₹1,23,144. Interest on non-cumulative FDs that pay out monthly or quarterly is not reinvested, so the total earned is lower.

Tax and safety
FD interest is added to your income and taxed at your slab rate. Banks deduct TDS once interest crosses the annual threshold. From tax year 2026-27, if your total income is below the taxable limit you submit Form 121 under the Income-tax Act, 2025, which replaced Forms 15G and 15H.
Deposits in banks, including small finance banks, are insured by DICGC up to ₹5 lakh per depositor per bank, covering principal and interest together.
Frequently asked questions
Is FD interest compounded monthly or quarterly?
Most banks compound cumulative FDs quarterly. Some pay interest monthly or quarterly on non-cumulative FDs instead of compounding it. Check your bank's FD terms.
Do senior citizens get a higher FD rate?
Most banks offer senior citizens an additional rate, often around 0.25-0.75 percentage points. Enter the senior citizen rate in the calculator to see the difference.
Is the calculator result before or after tax?
Before tax. Your actual return depends on your income tax slab and any TDS deducted by the bank.
