How to use the FD calculator
- Enter your depositType the amount, interest rate and tenure in years, months and days. Tick “Senior citizen” to add 0.5%.
- Choose how interest is paidCumulative FDs add interest to the deposit until maturity; payout FDs pay it to you every month, quarter, half-year or year.
- See the real returnAdd your tax rate and inflation to see what you keep after tax and what the maturity value is worth in today’s money.
Getting the most from fixed deposits
- Compare the effective yield, not just the rate. 7% compounded quarterly is an effective 7.19% a year; compounded yearly it is exactly 7%.
- Build an FD ladder. Split a large sum across 1-, 2- and 3-year deposits so some money matures every year and you can reinvest at the going rate.
- Mind the tax. At the 30% slab (31.2% with cess), a 7% FD compounded quarterly earns about 4.9% a year after tax – below inflation in many years. Tax-saving FDs (5-year lock-in) qualify for Section 80C under the old regime.
- Check premature withdrawal rules. Breaking an FD early usually means a penalty of 0.5–1% on the rate.
- Deposit insurance: in India, DICGC insures up to ₹5 lakh per depositor per bank, including interest.
Frequently asked questions
How is FD interest calculated?
For a cumulative FD the maturity value is A = P × (1 + r ÷ n)^(n × t), where P is the deposit, r the yearly rate, n the number of compounding periods a year (4 for quarterly) and t the tenure in years. The interest is A − P.
What will ₹1 lakh become in an FD for 5 years?
At 7% a year with quarterly compounding, ₹1,00,000 grows to about ₹1,41,478 in 5 years – interest of about ₹41,478. Enter your bank’s rate above for an exact figure.
What is the difference between cumulative and payout FDs?
In a cumulative FD the interest is added to your deposit and compounds, so you get more at maturity. In a payout (non-cumulative) FD the interest is paid to your bank account every month, quarter, half-year or year, and you get back just the deposit at maturity. Some banks pay slightly less than rate ÷ 12 on monthly payouts.
When does the bank deduct TDS on FD interest?
In India, banks deduct 10% TDS when your interest from that bank is more than ₹50,000 in a financial year, or ₹1,00,000 for senior citizens (limits from April 2025). You can submit Form 15G or 15H to avoid TDS if your total income is below the taxable limit. TDS isn’t the final tax – FD interest is taxed at your slab rate.
Is FD interest taxable?
Yes. FD interest is added to your income and taxed at your slab rate, whether it is paid out or reinvested. Enter your tax rate to see the interest you keep after tax.
Why do short FDs use simple interest?
Many Indian banks pay simple interest on deposits shorter than six months, because a quarter of compounding has barely started. Untick the option to compound short deposits instead.
Does a senior citizen get a higher FD rate?
Most Indian banks pay senior citizens (60 and above) about 0.5% more. Tick “Senior citizen” to add it – check your bank’s card rate, as some offer more on special tenures.
Is the FD calculator free?
Yes, completely free with no sign-up. Everything is calculated in your browser and nothing is saved.
