Your investment of ₹1,00,000.00 will grow to this amount in 5 years.
Formula: A = P × (1 + r/100/m)^(m×t), where m is compounding frequency and t is years.
A Fixed Deposit (FD) calculator is a financial tool that calculates the total amount you'll receive at maturity plus the interest earned on your principal investment. Banks and post offices offer fixed deposits as low-risk savings vehicles where you deposit a lump sum for a fixed period at a predetermined interest rate, which may be simple or compound depending on the product.
The calculator applies the appropriate formula—simple or compound interest—based on your inputs. For compound interest (most common for FDs), it calculates periodic compounding (quarterly, monthly, or daily) to show how your initial principal grows over the deposit period. You input the principal amount, annual interest rate, tenure in years, and compounding frequency; the tool outputs total maturity value and net interest earned.
A = P(1 + r/100/n)^(n*t)Where A is the maturity amount, P is principal, r is annual interest rate (%), n is compounding frequency per year (4 for quarterly, 12 for monthly, 365 for daily), and t is tenure in years.
| Input | Result | Notes |
|---|---|---|
| Principal: ₹100,000, Rate: 6.5% p.a., Tenure: 3 years, Compounding: Quarterly | Maturity Amount: ₹120,697; Interest Earned: ₹20,697 | Senior citizen FD rates are typically 0.5–1% higher; this example uses standard retail rates. |
| Principal: ₹500,000, Rate: 5.75% p.a., Tenure: 5 years, Compounding: Monthly | Maturity Amount: ₹654,842; Interest Earned: ₹154,842 | Longer tenures and higher principals demonstrate the compounding effect over time. |
| Principal: ₹50,000, Rate: 6% p.a., Tenure: 1 year, Compounding: Daily | Maturity Amount: ₹53,090; Interest Earned: ₹3,090 | Even small deposits earn meaningful interest; daily compounding yields marginally higher returns than quarterly. |
Compound interest (standard for FDs) calculates interest on interest earned previously; simple interest does not. For a ₹100,000 FD at 6% for 5 years, compound interest yields ~₹33,823, whilst simple interest yields ₹30,000. Most banks use compound interest.
Yes, but most banks charge a penalty of 0.5–1% interest or deduct interest accrued; some offer no penalty within 7 days. Check your bank's policy before investing. The calculator assumes you hold until maturity.
FD interest is taxable income. If interest exceeds ₹40,000 in a financial year, the bank deducts 20% as TDS. Use this calculator to find gross returns, then subtract TDS (20%) to estimate your net amount.
A 5-year FD locks funds but offers rate certainty; rolling annual FDs let you chase higher rates but carry reinvestment risk. The calculator helps compare both: input a 5-year rate vs. current 1-year rate × 5 scenarios.
FDs are not ideal for emergency funds (no quick access without penalty). Reserve 3–6 months of expenses in a liquid savings account; use FDs for surplus savings with a 2–3 year tenure for balance.
Yes. Post Office Savings Schemes (NSC, Kisan Vikas Patra, Senior Citizen Savings Scheme) often offer competitive or higher rates than banks. Use this calculator with your post office's rate to compare.
