What is a Fixed Deposit (FD)?

A Fixed Deposit (FD) is a financial instrument provided by banks and NBFCs which provides investors a higher rate of interest than a regular savings account, until the given maturity date. It is considered one of the safest investment options.

FD Maturity Formula (Quarterly Compounding)
M = P × (1 + r/4)^(4 × t)

Where M = Maturity amount, P = Principal deposit amount, r = Annual interest rate (decimal), t = Tenure in years.

Why Invest in FD?

  • Predictable Returns: FD interest is generally fixed according to the deposit terms when the deposit is booked, subject to the bank's stated conditions.
  • Safe Investment: Deposits up to ₹5 lakh are insured by DICGC in India.
  • Loan against FD: You can quickly get a loan up to 90% of your FD value without breaking it.
  • Tax Savings: Tax-saver FDs with a locking period of 5 years qualify for 80C deductions.

Frequently Asked Questions

What to know before you book a Fixed Deposit.

Most Indian banks compound FD interest quarterly by default, so maturity value is M = P × (1 + r/4)^(4×t), where P is the principal, r is the annual rate as a decimal, and t is the tenure in years. Some banks and NBFCs use monthly or half-yearly compounding instead — check your bank's specific terms, since it slightly changes the final number.
Yes, most banks allow premature withdrawal, but they typically charge a penalty of 0.5% to 1% on the interest rate, and you earn interest only for the period the deposit actually stayed with the bank. Tax-saver FDs with a 5-year lock-in generally can't be withdrawn early at all.
Yes. In India, FD interest is added to your total income and taxed at your applicable slab rate. Banks also deduct TDS if the interest earned in a financial year crosses the threshold set by the Income Tax Department. This calculator shows pre-tax maturity value only.
This tool assumes standard quarterly compounding at a constant rate for the full tenure. Real payouts can differ slightly due to the exact day-count convention your bank uses, mid-tenure rate changes on floating-rate deposits, or rounding rules — always confirm the exact figure on your bank's official FD receipt.
A cumulative FD reinvests interest each quarter so it compounds — this is what this calculator models. A non-cumulative FD pays interest out to you monthly, quarterly, or annually instead of reinvesting it, so your money grows more like simple interest and the payout amount will be lower than the maturity value shown here.
