FD Calculator
Calculate fixed deposit maturity amount and total interest with quarterly compounding for any bank FD.
How a fixed deposit grows
A fixed deposit (FD) locks a lump sum with a bank for a fixed term at a fixed interest rate. Interest compounds periodically — usually every quarter — so you earn interest on your interest. At maturity you receive the principal plus accumulated interest.
The formula
Maturity = P × (1 + r/(n×100))n×t, where P = principal, r = annual rate, n = compounding periods per year, t = years. Quarterly compounding uses n = 4.
Worked example
A ₹1,00,000 FD at 7% for 5 years, compounded quarterly, matures to about ₹1,41,478 — roughly ₹41,478 of interest. The same deposit compounded annually would grow slightly less, which is why compounding frequency matters.
FD vs other options
FDs offer capital safety and predictable returns, making them ideal for short-term goals and emergency funds. For long-term, inflation-beating growth, market-linked options like SIPs and lumpsum mutual fund investments have historically returned more (with higher risk).
How to use this calculator
Enter the deposit amount, interest rate, tenure, and compounding frequency. The result shows your maturity amount and total interest. Remember the figure is before tax — FD interest is taxed at your slab.
Frequently asked questions
How is FD maturity calculated?
Maturity = P × (1 + r/(n×100))^(n×t), where P is the principal, r is the annual rate, n is the number of compounding periods per year (4 for quarterly), and t is the tenure in years. Most Indian banks compound FDs quarterly.
How often is FD interest compounded?
Cumulative bank FDs are typically compounded quarterly. This calculator defaults to quarterly but lets you choose monthly, half-yearly, or annual compounding to match your bank.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate. Banks deduct TDS if interest exceeds the annual threshold. The maturity figure here is before tax.
What is the difference between FD and RD?
An FD is a single lump-sum deposit. A recurring deposit (RD) is a fixed monthly deposit. Both earn compound interest, but an RD's later instalments compound for less time.
Do senior citizens get higher FD rates?
Most banks offer senior citizens an extra 0.25–0.75% on FD rates. Enter your applicable rate to see the maturity at the senior rate.
Can I withdraw an FD early?
Usually yes, but banks charge a premature-withdrawal penalty and pay a slightly lower rate. The maturity shown assumes you hold the FD to term.
