FD Calculator – Fixed Deposit Returns Estimator
Calculate the maturity amount and interest earned on your fixed deposits with our easy-to-use FD calculator.
What is a Fixed Deposit Calculator?
A Fixed Deposit (FD) calculator is a financial tool designed to help investors estimate the maturity amount and interest earned on their fixed deposit investments. It takes into account the principal amount, interest rate, investment tenure, and compounding frequency to provide accurate projections of your returns.
Fixed deposits are one of the most popular and secure investment options in India, offering guaranteed returns at a fixed interest rate for a specified period. Unlike market-linked investments, FDs provide certainty of returns, making them an essential component of most investment portfolios, especially for risk-averse investors.
Our FD calculator also includes special features like senior citizen rates and different compounding frequency options (yearly, half-yearly, quarterly, and monthly), allowing you to compare various scenarios and choose the most beneficial option for your investment goals.
How to Use This Calculator
- Enter your principal amount - This is the amount you plan to deposit in your fixed deposit.
- Input the interest rate - Enter the annual interest rate offered by your bank or financial institution.
- Set your investment tenure - Specify how long you plan to keep your money in the FD (in years and months).
- Select compounding frequency - Choose how often the interest is compounded (yearly, half-yearly, quarterly, or monthly).
- Toggle senior citizen option if applicable - Enable this option if you're a senior citizen to include the additional interest rate benefit.
- View the results - The calculator will show your maturity amount, total interest earned, and year-by-year breakdown.
Calculation Formula & Example
The Formula
A = P(1 + r/n)^(nt)
Where:
- A = Maturity amount
- P = Principal amount
- r = Annual interest rate (in decimal form)
- n = Compounding frequency per year
- t = Time period in years
Example Calculation
Let's calculate the maturity amount for a fixed deposit with the following parameters:
- Principal amount (P): ₹1,00,000
- Interest rate (r): 7% per annum (0.07 in decimal)
- Tenure (t): 5 years
- Compounding frequency (n): Quarterly (4 times per year)
Step 1: Apply the formula
A = 1,00,000 × (1 + 0.07/4)^(4×5)
A = 1,00,000 × (1 + 0.0175)^20
A = 1,00,000 × (1.0175)^20
A = 1,00,000 × 1.4155
A = ₹1,41,550
Result:
- Principal amount: ₹1,00,000
- Interest earned: ₹41,550 (₹1,41,550 - ₹1,00,000)
- Maturity amount: ₹1,41,550

Calculator Use Cases
Calculate how your emergency fund can grow in fixed deposits while remaining relatively liquid and safe. FDs offer higher returns than savings accounts while providing the security needed for emergency funds.
Plan for short-term financial goals like buying a vehicle or funding a vacation by calculating exactly how much your FD investment will grow in 1-3 years, helping you determine the initial deposit needed.
For retirees, calculate how a lump sum amount can generate regular income through FD laddering (creating multiple FDs with different maturity periods) to ensure regular interest payouts while maintaining capital safety.
Evaluate tax-saving fixed deposits (5-year tax-saver FDs) to understand both the returns and the tax benefits under Section 80C, helping you make informed decisions about including them in your tax-saving portfolio.
