About the FD Calculator
Fixed Deposits are the most widely used savings instrument in India, with over ₹200 lakh crore deposited across banks. They offer guaranteed returns, DICGC insurance up to ₹5 lakh per bank, and zero market risk - making them the go-to choice for capital preservation and short-term goals.
Rates vary meaningfully across banks and tenures. Large banks like SBI and HDFC offer 6.0-6.5% for general public, while small finance banks (AU, Ujjivan, Jana) offer 8-9%+. Senior citizens get an additional 0.5% on most banks. Compounding frequency also matters: quarterly compounding (the Indian default) gives a slightly higher effective yield than annual compounding at the same stated rate.
The key tradeoffs with FDs are liquidity (breaking early costs 0.5-1% penalty), taxation (interest is fully taxable as income), and real returns (at 6% rate and 6% inflation, the real return is nearly zero). For goals beyond 3-5 years, equity SIPs or PPF typically outperform FDs after tax and inflation.

Verified in rate tableFD Maturity Amount
Cumulative: A = P × (1 + r/n)^(n×t) | Simple Interest: A = P × (1 + r×t/100)
P = Principal deposit · r = Annual interest rate (decimal) · n = Compounding frequency per year (quarterly = 4, monthly = 12) · t = Tenure in years · Effective Annual Rate = (1 + r/n)^n - 1
Worked Example
₹5 lakh FD at 6.5% for 3 years (quarterly compounding)
Maturity amount ≈ ₹6,04,706 · Interest earned ≈ ₹1,04,706 · Effective annual rate ≈ 6.65% · Simple interest at 6.5% would give only ₹5,97,500 - compounding earns ₹7,206 extra
Tips & Insights
- 1
TDS is deducted at 10% when your total FD interest from a single bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens). Submit Form 15G (below 60 years) or 15H (senior citizens) at the start of each FY if your total income is below the taxable limit - this prevents TDS deduction entirely.
- 2
DICGC insures only ₹5 lakh per depositor per bank across all accounts combined - not per FD. If you have ₹30 lakh to deposit, spread it across at least 6 banks. This applies to savings accounts, FDs, and RDs together.
- 3
FD laddering gives both better returns and liquidity. Instead of one ₹5 lakh FD for 5 years, create five ₹1 lakh FDs maturing in 1, 2, 3, 4, and 5 years. Each year one matures (providing liquidity), and you reinvest at the current rate - often higher than a locked long-term rate.
- 4
Tax-saving FDs (5-year lock-in, Section 80C) give ₹1.5 lakh deduction under the old tax regime. However, the interest earned is fully taxable. Compare the after-tax return (rate × (1 - tax bracket)) vs a PPF, which earns tax-free interest - PPF at 7.1% equals 10.1% pre-tax for someone in the 30% bracket.
- 5
Quarterly compounding gives a higher effective rate than annual compounding at the same stated rate. At 6.5%: annual compounding EAR = 6.5%, quarterly EAR = 6.65%, monthly EAR = 6.70%. When comparing FDs across banks, always compare EAR - not the nominal rate.
- 6
Breaking an FD early costs you 0.5-1% on the applicable (lower) rate for the period held. On a ₹5 lakh FD at 6.5% broken at 2 years (applicable rate 6%), the penalty of 0.5% costs about ₹5,000. For emergencies, keep 3-6 months expenses in a savings account or liquid fund instead of relying on FD breakage.

Small Finance Banks (SFBs) are also DICGC insured - AU Small Finance Bank, Ujjivan, Jana, ESAF, etc. offer 7.5-9%+ on various tenures. Keeping up to ₹5 lakh in an SFB FD is as safe as a large bank FD from an insurance standpoint, with significantly higher returns.
Why this matters for you
FDs occupy a specific and irreplaceable role in a financial portfolio: they are the only major instrument that combines guaranteed returns, deposit insurance, and fixed income. For goals with a defined 1-5 year horizon - a home down payment, a child's school fees, a business reserve - FDs are unbeaten. The question is not whether to use FDs, but which bank, which tenure, and how much to allocate vs higher-return instruments.
The real enemy of FD wealth is the combination of tax and inflation. At a 6.5% FD rate, a person in the 30% tax bracket earns only 4.55% post-tax. With India's CPI inflation averaging 5-6%, the real return is negative - the purchasing power of the money actually shrinks. This is why FDs are suitable for capital preservation in the short term, but unsuitable as the primary savings vehicle for long-term goals like retirement or education corpora.
The TDS mechanism catches many FD investors off-guard. Banks deduct TDS each year on cumulative FDs even though you receive the money only at maturity. This means you pay tax on interest you haven't physically received yet, creating a cash flow mismatch. Submitting Form 15G/15H at the start of each financial year eliminates this problem for those below the taxable income threshold - a simple step that saves 10% of your annual interest with zero effort.
