What is an FD Calculator?
A Fixed Deposit (FD) calculator is a free online financial tool that helps you estimate the maturity amount and interest earned on your fixed deposit investment. By entering the principal amount, interest rate, tenure, and compounding frequency, you can instantly see how your money will grow over time.
Our FD calculator supports cumulative and non-cumulative FDs with quarterly, half-yearly, annual, and monthly compounding. For non-cumulative FDs, you can see exact monthly, quarterly, half-yearly, or yearly payout amounts and a complete payout schedule. It also provides a year-by-year breakdown so you can see exactly how your investment grows each year.

FD Interest Calculation Formula
Fixed deposit interest is calculated using the compound interest formula:
A = P × (1 + r/n)^(n×t)
- A = Maturity Amount (final value of your FD)
- P = Principal Amount (initial investment)
- r = Annual interest rate (in decimal form, e.g., 7% = 0.07)
- n = Number of times interest is compounded per year
- t = Tenure in years
For example, if you invest ₹1,00,000 at 7% annual interest compounded quarterly for 5 years: A = 100000 × (1 + 0.07/4)^(4×5) = 100000 × (1.0175)^20 = ₹1,40,255.
Types of Fixed Deposits
Banks offer several types of FDs to suit different investment needs:
- Standard FD: The most common type with a fixed interest rate and tenure. Suitable for conservative investors.
- Tax-Saving FD: Lock-in period of 5 years under Section 80C. Offers tax deduction up to ₹1.5 lakh per year.
- Cumulative FD: Interest is compounded and paid at maturity. Offers higher returns due to compounding.
- Non-Cumulative FD: Interest is paid periodically (monthly, quarterly, half-yearly, or annually). Ideal for those needing regular income.
- Senior Citizen FD: Higher interest rates (0.25% to 0.75% extra) for customers aged 60 and above.
- Flexi FD: Combines the benefits of a savings account and FD. Auto-sweeps excess funds into FD for higher returns.
Benefits of Investing in Fixed Deposits
- Guaranteed Returns: Unlike stocks or mutual funds, FD returns are fixed and guaranteed by the bank.
- Low Risk: FDs are one of the safest investment options with virtually no risk of loss.
- Flexible Tenure: Choose tenure from 7 days to 10 years based on your financial goals.
- Loan Against FD: Many banks allow you to take a loan against your FD without breaking it.
- Tax Benefits: Tax-saving FDs qualify for deductions under Section 80C of the Income Tax Act.
- Auto-Renewal: Most banks offer auto-renewal options so your FD continues earning after maturity.
Frequently Asked Questions
What is an FD calculator?
An FD (Fixed Deposit) calculator is a free online tool that calculates the maturity amount and interest earned on your fixed deposit investment. It uses the compound interest formula to give you accurate returns based on principal, interest rate, tenure, and compounding frequency.
How is FD interest calculated?
FD interest is calculated using the compound interest formula: A = P × (1 + r/n)^(n×t), where A is the maturity amount, P is the principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the tenure in years.
What is the difference between simple and compound interest on FD?
Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal plus accumulated interest. Compound interest yields higher returns because you earn interest on interest. Most banks offer compound interest on FDs.
What is the minimum amount to open an FD?
The minimum amount varies by bank, but typically ranges from ₹1,000 to ₹10,000 in India. Some banks allow FDs starting from as low as ₹500. Our calculator works with any amount you enter.
What is the typical FD interest rate?
FD interest rates in India typically range from 3% to 9% per annum depending on the bank, tenure, and customer type. Senior citizens usually get 0.25% to 0.75% higher rates. Our calculator lets you enter any rate.
Can I calculate FD with quarterly compounding?
Yes. Our FD calculator supports quarterly, half-yearly, annual, and monthly compounding frequencies. Quarterly compounding is the most common method used by banks in India and yields higher returns than annual compounding.
Is this FD calculator free to use?
Yes, our FD calculator is completely free with no limits. You can calculate unlimited FD returns without creating an account. All calculations happen in your browser.
What is the difference between cumulative and non-cumulative FD?
In a cumulative FD, interest is reinvested and paid at maturity, giving you higher returns due to compounding. In a non-cumulative FD, interest is paid out periodically (monthly, quarterly, half-yearly, or yearly) — ideal for those needing regular income while keeping the principal intact.
Which is better: cumulative or non-cumulative FD?
Cumulative FDs offer higher returns because of compounding. Non-cumulative FDs are better if you need regular income, such as retirees or those with recurring expenses. Choose based on your financial goals.
