What is the Fixed Deposit (FD) Calculator?

A fixed deposit (FD) is a deposit where you lock a sum with a bank or NBFC for a fixed tenure at a predetermined interest rate. An FD calculator computes the maturity amount and the interest you will earn, given your deposit, rate, tenure and how often interest is compounded.

How does it work?

FD interest is compounded at a set frequency — usually quarterly in India. The calculator applies the compound interest formula, adding interest to the principal each compounding period so that subsequent interest is earned on a growing balance until maturity.

Formula

A = P × (1 + r/n)^(n·t)

  • A = maturity amount
  • P = principal deposited
  • r = annual interest rate (as a decimal)
  • n = compounding periods per year
  • t = tenure in years

Example calculation

A ₹1,00,000 FD at 7% p.a. compounded quarterly for 5 years matures to about ₹1,41,478 — earning roughly ₹41,478 in interest, slightly more than simple interest would give because of compounding.

Benefits

  • +Capital protection with assured, predictable returns.
  • +Flexible tenures and choice of payout or cumulative options.
  • +Higher rates for senior citizens and easy loan-against-FD facility.

Limitations

  • !Returns may not beat inflation, especially after tax.
  • !Premature withdrawal usually attracts a penalty.
  • !Interest is fully taxable as per your income slab.

Conclusion

Fixed deposits suit conservative savers and short-to-medium-term goals where safety matters more than high returns. Compare cumulative versus payout options and remember to account for tax when judging the real return.

Frequently Asked Questions

How is FD maturity calculated?+

It uses compound interest: A = P × (1 + r/n)^(n·t), where n is the number of compounding periods per year, typically quarterly for Indian FDs.

What is cumulative vs non-cumulative FD?+

In a cumulative FD interest is reinvested and paid at maturity; in a non-cumulative FD interest is paid out periodically (monthly, quarterly, etc.).

Is FD interest taxable?+

Yes. FD interest is added to your income and taxed at your slab rate. Banks deduct TDS once interest crosses the threshold in a year.

Can I break an FD early?+

Yes, but premature withdrawal usually reduces the applicable interest rate and may carry a penalty.

Do senior citizens get higher rates?+

Most banks offer senior citizens an extra 0.25%–0.75% over the standard FD rate.

How often is FD interest compounded?+

Indian banks typically compound FD interest quarterly, but you can select other frequencies in the calculator to compare outcomes.
