What is a Fixed Deposit?
A fixed deposit (FD) is a savings product offered by banks and NBFCs where you deposit a lump sum for a fixed period at an interest rate agreed at the start. In a cumulative FD, interest is reinvested and paid together with the principal at maturity.
How is FD maturity amount calculated?
This calculator uses the standard compound-interest formula:
A = P × (1 + r/m)^(m×t)
P is the deposit, r is the annual rate as a decimal, m is the number of compounding periods per year, and t is the tenure in years (total months ÷ 12). Interest earned is A − P.
What is FD compounding frequency?
Compounding frequency is how often earned interest is added to your deposit so it starts earning interest itself. Monthly = 12 times a year, quarterly = 4, half-yearly = 2 and yearly = 1.
Monthly vs quarterly vs half-yearly vs yearly compounding
For the same rate and tenure, more frequent compounding gives a slightly higher maturity amount. For ₹1,00,000 at 7% for 5 years, the difference between monthly and yearly compounding is a few thousand rupees. Choose the frequency your bank actually applies.
How much interest can an FD earn?
Interest depends on the deposit amount, rate, tenure and compounding. Longer tenures and higher rates increase interest because each period's interest earns further interest. Compare this with market-linked options using the SIP Calculator, or plan regular withdrawals from a corpus with the SWP Calculator.
A simple worked example
Deposit ₹1,00,000 at 7% per year for 5 years with quarterly compounding: r/m = 0.07 ÷ 4 = 0.0175 and m×t = 4 × 5 = 20.
A = 1,00,000 × (1.0175)^20 ≈ ₹1,41,478, so interest earned is about ₹41,478.
Important note
This calculator provides an estimate based on the selected interest rate, tenure and compounding frequency. Actual bank FD maturity may differ according to the bank's product terms, compounding conventions, payout options, premature withdrawal rules and applicable taxes.
TDS and income tax are not included in this calculator. Actual tax treatment depends on applicable rules. If you are planning a loan instead, try the EMI Calculator or the Loan Calculator.
Frequently asked questions
What is an FD calculator?
An FD calculator estimates the maturity amount and interest earned on a fixed deposit from the deposit amount, annual interest rate, tenure and compounding frequency.
How is FD maturity amount calculated?
It uses the compound-interest formula A = P × (1 + r/m)^(m×t), where P is the deposit, r is the annual rate as a decimal, m is the number of compounding periods per year and t is the tenure in years.
What is the difference between principal and interest earned?
Principal is the amount you deposit. Interest earned is what the bank pays on top of it, calculated as maturity amount minus principal.
What is quarterly compounding in an FD?
Interest is calculated and added to the deposit every three months (four times a year), so later interest is earned on both the principal and the interest already added.
Which compounding frequency should I select?
Select the frequency stated in your bank's FD terms. Many Indian banks compound cumulative FDs quarterly, but this varies by bank and product.
Can I calculate FD returns at 0% interest?
Yes. At 0% the maturity amount equals the principal and interest earned is ₹0.
Does this calculator include TDS or income tax?
No. TDS and income tax are not included. FD interest may be taxable and subject to TDS; actual tax treatment depends on applicable rules and your situation.
Can actual bank FD maturity differ from this calculator?
Yes. Banks may use different compounding conventions, day counts, rounding, payout options and premature withdrawal rules, so the actual maturity can differ from this estimate.
