How to calculate FD maturity amount

Enter your principal, interest rate, tenure, and compounding frequency to instantly see your Fixed Deposit maturity value and total interest earned.

  1. 01

    Enter the principal amount

    Type the amount you want to deposit in the FD. This is the lump sum you'll invest, for example, ₹1,00,000 or ₹5,00,000.

  2. 02

    Set the interest rate and tenure

    Enter the annual interest rate offered by your bank (e.g., 7.25%) and the FD tenure in years, in quarter-year steps (0.25 is three months). Rates vary by bank, tenure, and whether you're a senior citizen.

  3. 03

    Choose the compounding frequency

    Select how often interest is compounded: monthly, quarterly, half-yearly, or annually. Most Indian banks compound quarterly by default, but this varies.

  4. 04

    Read your maturity amount and interest earned

    The calculator instantly shows your maturity value, total interest earned, and effective annual yield. Use this to compare FDs across different banks and tenures.

What people use it for

Fixed Deposits are India's most widely used savings instrument. Here's how the calculator helps you make better FD decisions.

Comparing bank FD offers

Different banks offer different rates and compounding frequencies. Use the calculator to find the actual maturity amount for each offer and pick the best one.

Senior citizen FD planning

Senior citizens typically get 0.25%–0.50% higher rates. Enter the senior citizen rate to see the additional interest earned over the tenure.

Short-term parking of funds

Calculate returns on short-term FDs (7 days to 1 year) for parking emergency funds, bonus payouts, or proceeds from asset sales.

Tax-saving FD (5-year lock-in)

5-year tax-saving FDs qualify for Section 80C deduction. Calculate the maturity amount to weigh them against PPF, ELSS, and other 80C options.

Laddering strategy

FD laddering splits your investment across multiple FDs with staggered maturities. Calculate each rung separately to plan liquidity and reinvestment timing.

Retirement income planning

Retirees use FDs for predictable income. Calculate how much principal you need to generate a target monthly interest payout at current rates.

Worked example: ₹1 lakh at 7% for 3 years

The calculator uses A = P × (1 + r ÷ n)n × t, where n is how often interest is added. Most Indian bank FDs compound quarterly, so ₹1,00,000 at 7% for 3 years matures at ₹1,23,144, with ₹23,144 of interest.

CompoundingMaturity valueInterest

Monthly₹1,23,293₹23,293
Payout every quarter (simple)₹1,00,000 back₹21,000 paid out

The last row is the payout option, where interest is paid to your account instead of being added to the deposit. You receive ₹21,000 over the three years, ₹2,144 less than the cumulative FD, because the paid-out interest doesn't earn anything further. Choose payout only if you need the income.

Tax and other things to check

  • FD interest is added to your income and taxed at your slab rate. Banks deduct TDS once a year's interest passes a threshold; check the current limit, which is higher for senior citizens, and submit Form 15G or 15H if your income is below the taxable limit.
  • Breaking an FD early usually costs a penalty of around 0.5–1% on the rate, and you earn the lower rate for the shorter period.
  • Bank deposits are insured by DICGC up to ₹5 lakh per depositor per bank, including interest.
  • The calculator assumes the rate stays fixed for the term, which is true for standard FDs.

Frequently asked questions

Common questions about FD interest calculation, compounding, TDS, and how the calculator works.

Yes, completely free. No account required, no limits on calculations.
The calculator supports monthly, quarterly, half-yearly, and annual compounding. Most Indian banks (SBI, HDFC, ICICI, Axis, etc.) compound interest quarterly by default.
The standard compound interest formula is used: A = 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.
The calculator shows gross interest before TDS. Banks deduct TDS at 10% if your annual FD interest exceeds ₹40,000 (₹50,000 for senior citizens). Submit Form 15G/15H to avoid TDS if your total income is below the taxable limit.
Most FDs use compound interest, where interest earned in each period is added to the principal and earns interest in subsequent periods. Simple interest FDs calculate interest only on the original principal. These are less common and yield lower returns.
Yes. Simply enter the senior citizen interest rate (typically 0.25%–0.50% higher than the regular rate) in the interest rate field. The calculator works the same way regardless of the rate you enter.
Yes. The tool is fully responsive and works on any modern smartphone or tablet browser.
No. All calculations happen entirely in your browser. The amounts and rates you enter are never sent to any server.
