Enter the deposit, rate, and tenure — quarterly compounding by default, matching how Indian banks actually calculate FD interest.
Fixed deposits use compound interest: maturity = P × (1 + r/n)^(n×t), where P is your deposit, r the annual rate, n the compounding frequency per year, and t the tenure in years. Most Indian banks compound quarterly, which is the default above.
Yes — FD interest is fully taxable as "income from other sources" at your slab rate, and banks deduct TDS at 10% if annual interest exceeds ₹40,000 (₹50,000 for senior citizens). The maturity figure above is pre-tax.
Premature withdrawal typically incurs a penalty of 0.5–1% on the interest rate, and the FD earns the rate applicable for the period actually held, not the originally booked rate — so breaking a 5-year FD after 1 year usually earns notably less than a fifth of the projected interest.
An FD is a one-time lump-sum deposit. If you're depositing a fixed amount every month instead, use the RD calculator.
Worked example: ₹1,00,000 for 5 years at 7% compounded quarterly: 100000 × (1 + 0.07/4)^20 ≈ ₹1,41,478 — about ₹41,478 of interest.
