FD Calculator: Calculate your fixed deposit returns

Fixed deposits remain one of the most common savings choices for Indian households. The interest rate is locked at the time of deposit and does not change, which is what sets FDs apart from market-linked options.

Figuring out the exact maturity amount by hand involves compounding calculations that vary by bank and tenure. Put in the deposit amount, interest rate, and tenure above and the calculator shows the maturity value and total interest earned right away.

How can an online FD calculator help you?

Fixed deposits provide certainty, but compounding interest on a quarterly basis requires precise mathematical formulas.

Here is what this calculator does for you.

  • ✓Calculate your exact maturity value and interest returns instantly.
  • ✓Avoid manual compound interest calculation mistakes.
  • ✓Plan short-term and long-term savings goals with total accuracy.
  • ✓Completely free to use with zero logins or registration steps.

This FD calculator removes all the guesswork. If you want to calculate fixed deposit returns for any investment amount (short-term or long-term goals). Just enter your principal deposit, interest rate, and tenure above.

How to use this FD calculator

Put in the deposit amount, the interest rate your bank is offering, and how long you want to stay invested. The maturity amount and total interest show up straight away. No account needed.

How does FD interest compounding work?

Most Indian banks use quarterly compounding for fixed deposits. Interest is added to your principal base every three months, which then earns interest itself.

A = P × (1 + r/n)n×t
VariableWhat it means
AMaturity amount: what you receive at the end
PPrincipal: your initial deposit amount
rAnnual interest rate (expressed as a decimal)
nCompounding frequency per year (4 for quarterly)
tTenure in years

This calculator computes your returns using this standard formula. Put in your numbers above and the result appears right away.

Factors affecting your FD returns

Three components determine your final fixed deposit payout. Adjust the inputs above to see how they change the results in real time.

Deposit principal

Principal is the base. The larger your initial deposit, the higher the absolute interest you earn.

Interest rate

The interest rate directly drives the growth. Minor changes in interest rates make a massive difference over long tenures. Here is how a Rs. 1,00,000 deposit compounds over 5 years.

Interest rateMaturity amountInterest earned
6.0%Rs. 1.34 lakhRs. 34,685
7.0%Rs. 1.41 lakhRs. 41,477
8.0%Rs. 1.48 lakhRs. 48,594

Interest rates are set by individual banks based on RBI repo rate changes. Senior citizens typically receive an additional 0.25% to 0.50% p.a. on their deposits.

Tenure

Time determines the compounding periods. A longer tenure allows compounding to work on a larger accumulated interest base over time.

Frequently asked questions

Yes, most banks allow premature withdrawal. Breaking a deposit early means you earn interest at a lower rate than originally agreed. Some lenders also charge a penalty fee of 0.5% to 1%.
Yes, fully. FD interest is not exempt anywhere. It lands in your total income and your slab rate applies. Banks cut 10% TDS when the annual interest crosses Rs. 40,000. Senior citizens get Rs. 50,000 as the limit. Below the taxable threshold altogether? Form 15G or 15H submitted to the bank handles it. No TDS gets cut.
Compounding is the key. A cumulative FD keeps reinvesting the interest every quarter and pays everything out at maturity. The corpus grows faster because interest earns interest. A non-cumulative FD pays out interest at regular intervals, monthly or quarterly, without reinvesting it. The maturity amount is lower but you get a steady payout through the tenure.
Up to Rs. 5 lakh per depositor is covered. DICGC handles this coverage. It is an RBI subsidiary and all scheduled banks fall under it. Scheduled banks are all covered under this scheme. Amounts above Rs. 5 lakh at a single bank are not protected by this guarantee.
Depends on what the money is for. FDs lock in a fixed rate and the maturity amount is known upfront. SIPs in mutual funds have no guaranteed return but have historically outpaced inflation over 10 years or more. The trade-off is certainty on one side and growth potential on the other. Both numbers are visible on this site. The FD Calculator and the SIP Calculator show the difference for any amount you put in.
Compounding frequency is usually the reason. This calculator assumes quarterly compounding, which is the standard across most banks. Some banks use monthly compounding or simple interest for shorter tenures. The final maturity amount shifts depending on which method applies. Check your bank's account statement or rate card for the exact compounding terms they use.
Hard five-year lock-in. No breaking it early, no exceptions. The upside is that the amount deposited, up to Rs. 1.5 lakh, counts toward your Section 80C limit. One catch though: the interest it earns is still taxable. Same slab rate as any other FD.
Not always. Banks set rates based on their own liquidity needs and where they think rates are headed. A 1-year or 2-year FD often pays more than a 5-year one. The only way to know is to check the bank's current rate card directly. Rates change frequently and vary across banks.

Fixed deposit (FD) vs market-linked growth: A comparative example

Consider a comparative example of allocating Rs. 5,00,000 over a 5-year investment period using two different strategies: a low-risk bank Fixed Deposit and a market-linked equity mutual fund.

  • Strategy A:
    Allocation to a Fixed Deposit at 7.5% p.a. compounded quarterly.
  • Strategy B:
    Allocation to a market-linked equity mutual fund averaging 10% p.a. returns.

What are the final values after 5 years?

Result a (fixed deposit)

Total Deposited: Rs. 5,00,000

Interest earned: Rs. 2,24,974

Maturity value: Rs. 7,24,974

Result b (market-linked fund)

Total invested: Rs. 5,00,000

Gains Earned: Rs. 3,05,255

Final Value: Rs. 8,05,255

The additional return on the market-linked investment highlights the trade-off between risk and certainty. Fixed deposits are suitable when capital protection is the primary goal. Use our SIP Calculator alongside this to plan your monthly long-term growth investments.

Important note

This FD calculator provides estimates based on standard quarterly compounding. Actual returns may vary slightly depending on the bank's specific compounding frequency and policies.
