💡 Tax Info: Interest earned on FD is taxable as per your income tax slab. TDS is deducted if interest exceeds ₹40,000/year (₹50,000 for senior citizens).
👴 Senior Citizen: Most banks offer 0.25% - 0.50% higher interest rates for senior citizens (60+ years).
What is a fixed deposit (FD)?
A fixed deposit lets you park a lumpsum with a bank, small finance bank, post office (as a Time Deposit) or NBFC for a chosen period – from a few days to ten years – at an interest rate fixed on the day you invest. Because the return is known in advance, FDs are widely used for emergency funds, short-term goals and the stable portion of a portfolio.
FDs come in two main forms. In a cumulative FD, interest is reinvested and paid with the principal at maturity – this is what the calculator models. In a non-cumulative FD, interest is paid out monthly, quarterly or yearly, which suits retirees who need regular income.
How is FD maturity calculated?
- A = maturity amount
- P = deposit amount
- r = annual interest rate as a decimal
- n = compounding periods per year (4 for quarterly, the common choice for Indian bank FDs)
- t = tenure in years
Interest earned = A − P.
Worked example: ₹1,00,000 for 5 years at 7%
- Deposit: ₹1,00,000; rate 7% p.a.; tenure 5 years; quarterly compounding
- Calculation: ₹1,00,000 × (1 + 0.07/4)^20
- Interest earned: ₹41,478
- Maturity amount: ₹1,41,478
- Effective annual yield: about 7.19% (because of quarterly compounding)
With yearly compounding the same deposit would grow to ₹1,40,255, and with monthly compounding to ₹1,41,763. Always compare FDs on the same compounding basis, or on their effective annual yield.
Types of fixed deposits
- Regular FD: any tenure offered by the bank, with premature withdrawal usually allowed at a penalty.
- Tax-saver FD: 5-year lock-in; deposits up to ₹1.5 lakh qualify under Section 80C (old tax regime).
- Senior citizen FD: most banks offer residents aged 60+ a higher rate than the general public.
- Post Office Time Deposit: government-backed deposits of 1, 2, 3 and 5 years at rates notified quarterly.
- Corporate / NBFC FD: may offer higher rates, but carry credit risk and no DICGC cover.
Tax on FD interest
FD interest is taxable every year at your income-tax slab rate, even on cumulative FDs where you receive nothing until maturity. Banks deduct TDS (10% if your PAN is on record, higher if not) once interest crosses the threshold in the Income Tax Act. TDS is not the final tax – if you are in a higher slab you pay the balance; if your income is below the taxable limit, submit Form 15G/15H at the start of the year. Post-tax, an FD’s real return after inflation can be small, which matters for long-term goals.
Premature withdrawal and loans against FD
Most banks let you break a regular FD early but pay interest at the rate applicable for the period actually held, minus a penalty (commonly 0.5%–1%). Tax-saver FDs cannot be broken before five years. If you need money only briefly, a loan or overdraft against the FD – typically up to 90% of the deposit at a rate slightly above the FD rate – can be cheaper than breaking it.
Tips for FD investors
- Ladder your deposits: split money across tenures (say 1, 2 and 3 years) so part matures every year.
- Stay within insurance limits: keep deposits per bank within the ₹5 lakh DICGC cover if safety is the priority.
- Compare post-tax returns: for long horizons, compare with PPF or debt mutual funds after tax.
- Check auto-renewal terms: renewed FDs earn the rate prevailing on the renewal date, which may be lower.
FD Calculator FAQs
What is a fixed deposit?
A fixed deposit (FD) is a deposit with a bank, post office or NBFC for a fixed tenure at an interest rate that is locked in when you open it. It usually pays more than a savings account, and the rate does not change during the tenure even if market rates move.
How is FD maturity calculated?
For a cumulative FD, maturity value A = P × (1 + r/n)^(n × t), where P is the deposit, r the annual rate as a decimal, n the number of compounding periods per year and t the tenure in years. Most Indian banks compound FD interest quarterly.
Can I use this calculator for SBI, HDFC Bank, ICICI Bank or Post Office FDs?
Yes, for cumulative deposits. Enter the rate your bank quotes for your tenure and choose its compounding frequency (usually quarterly). Results can differ slightly from a bank’s own figure because of day-count conventions or tenures quoted in days rather than whole years.
Does it calculate monthly interest payouts?
No. The calculator shows the maturity value of a cumulative FD, where interest is reinvested. For non-cumulative FDs that pay interest monthly or quarterly, banks pay at the agreed interval and often use a slightly discounted rate for monthly payouts; check the payout amount with your bank.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate. Banks deduct TDS when your interest crosses the threshold set under the Income Tax Act (higher for senior citizens). If your total income is below the taxable limit, you can submit Form 15G (or Form 15H if you are a senior citizen) to avoid TDS.
Can I use it as a tax-saver FD calculator?
Yes. Tax-saving FDs have a 5-year lock-in, so set the tenure to 5 years and enter the bank’s rate. Deposits up to ₹1.5 lakh qualify for a Section 80C deduction under the old tax regime, but the interest earned is still taxable.
Is my money in an FD safe?
Deposits with banks are insured by DICGC up to ₹5 lakh per depositor per bank, covering principal and interest together. NBFC and corporate FDs are not covered by DICGC, so check their credit rating before investing.
