Calculate maturity amount and interest earned on your Fixed Deposits (FD) online with flexible compounding options.
Fixed Deposit (FD) Calculator
A fixed deposit (FD) is a secure, low-risk financial investment option offered by banks, post offices, and Non-Banking Financial Companies (NBFCs). With FDs, you deposit a lump sum of money for a fixed period at a set interest rate. Unlike regular savings accounts where interest rates can fluctuate, FDs lock in a guaranteed interest rate for the entire tenure, providing peace of mind and predictable returns upon maturity. It is one of the most popular savings instruments due to its safety and assured returns.
How Does Our Fixed Deposit (FD) Calculator Help You?
Calculating the exact maturity value of a fixed deposit manually can be incredibly tedious, especially when dealing with compound interest compounded quarterly. Our online FD calculator simplifies this process entirely. By inputting your principal investment amount, the annual rate of interest, and the tenure, you can instantly see the exact maturity amount and the interest you will earn. This helps you compare different bank FD schemes, estimate your future wealth growth, and plan your financial goals with high precision.
The Mathematics Behind Fixed Deposit Calculations
Fixed deposits can earn interest in two different ways depending on the scheme: compound interest (which is the industry standard) and simple interest. For standard bank FDs, interest is compounded quarterly (four times a year). The formula used is:
Where:
- A is the final maturity amount.
- P is the principal investment amount.
- r is the annual interest rate (in decimal format, e.g., 6.5% = 0.065).
- n is the number of times interest compounds per year (n = 4 for quarterly).
- t is the total duration of investment in years.
Example Calculations
If you invest ₹1,00,000 for 5 years at an interest rate of 6.5% p.a. with quarterly compounding:
- P = ₹1,00,000
- r = 6.5 / 100 = 0.065
- n = 4 (compounded quarterly)
- t = 5 years
- A = 100,000 × (1 + 0.065 / 4)4 × 5 ≈ ₹1,38,042
- Estimated returns = ₹1,38,042 - ₹1,00,000 = ₹38,042
Tax Implications on Fixed Deposits
It is essential to remember that the interest earned on fixed deposits is fully taxable according to your income tax slab. Banks are required to deduct Tax Deducted at Source (TDS) if your total interest income across all branches of a bank exceeds ₹40,000 in a financial year (₹50,000 for senior citizens). If your total income is below the taxable limit, you can submit Form 15G or 15H to prevent the bank from deducting TDS. Additionally, banks offer special tax-saving FDs which have a mandatory lock-in period of 5 years and qualify for tax deductions under Section 80C of the Income Tax Act.
Key Parameters Influencing FD Interest Rates
- Principal Amount: Larger deposits sometimes attract different rates of interest, particularly bulk deposits above ₹2 Crores.
- Tenure: FDs can range from 7 days up to 10 years. Banks structure interest rates according to the tenure, often offering peak interest rates for mid-term deposits (e.g., 1 to 3 years).
- Age of the Depositor: Senior citizens (aged 60 and above) are typically offered an additional interest rate benefit, usually 0.50% higher than the standard rate.
- Economic Factors: RBI repo rate changes, liquidity conditions in the banking system, and inflation levels directly influence the interest rates offered by commercial banks.
Fixed Deposits vs. Recurring Deposits (RD)
While both offer guaranteed returns at a fixed rate of interest, they serve different savings styles. A Fixed Deposit requires a one-time lump-sum investment at the beginning of the tenure. On the other hand, a Recurring Deposit (RD) allows you to invest a fixed sum monthly, making it suitable for salaried individuals who want to build up savings gradually.

How it Works & Formula
Calculates the maturity amount of a Fixed Deposit (FD) compounded quarterly by default. P is the principal amount, r is the annual rate of interest, n is the number of times interest compounds per year (typically 4 for quarterly), and t is the tenure in years.
Practical Examples
Depositing ₹1,00,000 for 5 years at an interest rate of 6.5% p.a. compounded quarterly yields a maturity amount of ₹1,38,042, with ₹38,042 earned as interest.
