India Fixed Deposit Calculator — FD Returns, Interest & Tax Explained
Calculate your fixed deposit maturity amount, compare FD interest rates across tenures, and understand the tax impact on FD returns — all using Moneykar's free FD calculator.
Fixed deposits remain one of the most popular savings instruments in India — and for good reason. They offer guaranteed returns, capital safety (up to ₹5L per bank under DICGC insurance), and predictable income. A FD calculator helps you compare banks, tenures, and compounding frequencies before locking in your money.
What an FD calculator tells you
Enter three inputs — principal amount, interest rate, and tenure — and the calculator returns:
- Maturity amount — what you receive at the end of the FD period.
- Total interest earned — the rupee value of your return.
- Effective annual yield — useful for comparing FDs that compound at different frequencies (quarterly vs annually).
How FD interest is calculated
Banks compound FD interest quarterly for most cumulative deposits. The formula is:
M = P × (1 + r/4)^(4×t)
For a ₹5 lakh FD at 7.5% for 3 years with quarterly compounding:
M = 5,00,000 × (1 + 0.075/4)^12 = ₹6,25,963 (approximately)
FD vs SIP: which is right for you?
| Factor | FD | SIP (Equity) |
|---|---|---|
| Return | 6.5–9.5% (fixed) | 10–15% (historical, not guaranteed) |
| Risk | None (DICGC insured up to ₹5L) | Market risk |
| Liquidity | Premature withdrawal with penalty | Can exit anytime (except ELSS) |
| Tax on returns | Added to income, taxed at slab rate | LTCG 12.5% above ₹1.25L |
| Best for | Emergency fund, capital preservation | Wealth creation, 5+ year goals |
Tax on FD: what you actually take home
FD interest is fully taxable as "Income from Other Sources." If you're in the 30% tax bracket, your 8% FD gives you an effective post-tax return of only 5.6%. This makes tax-efficient instruments like PPF, ELSS, or debt mutual funds (for long-term) worth considering for wealth creation beyond emergency reserves.
Senior citizens get an additional deduction of up to ₹50,000/year on FD interest under Section 80TTB, making FDs more attractive for retirees.
How to choose the right FD tenure
- 1–2 year FDs — for short-term goals or parking money until a decision is made.
- 3–5 year FDs — often offer the best rates; suitable for medium-term goals.
- Tax-saving FD (5 years) — qualifies for Section 80C deduction (up to ₹1.5L/year) but has a mandatory 5-year lock-in and interest is taxable.
