What Is FD?
A Fixed Deposit (FD) is a type of investment offered by banks and financial institutions where you deposit a lump sum amount of money for a fixed tenure at a predetermined interest rate.
It is considered a safe and low-risk investment option because the principal amount is guaranteed and the returns are fixed for the entire duration of the deposit.

|---|---|---|
| Risk | Low, guaranteed returns | Varies (low to high depending on fund type) |
| Returns | Fixed, low returns (3%–7%) | Market-linked, higher returns (5%–15%) |
| Liquidity | Low, penalty for early withdrawal | High, but market conditions affect returns |
| Taxation | Taxable interest, TDS deducted | Capital gains tax (LTCG/STCG) and dividend tax |
| Investment Tenure | Short to medium term (7 days to 10 years) | Short to long term (depends on fund type) |
| Minimum Investment | ₹1,000 to ₹5,000 | ₹500 for SIP, ₹1,000 to ₹5,000 lump sum |
| Diversification | No diversification | Instant diversification across assets |
| Suitability | Safe for conservative investors, short-term goals | Suitable for long-term goals and higher risk tolerance |
What Is A Fixed Deposit Calculator?
A Fixed Deposit Calculator is an online tool that enables investors to calculate the maturity value of their FD investments.
The FD calculator is designed to simplify the complex process of calculating compound interest, which is commonly applied to FDs.
By using this tool, you can determine the total return on your investment, helping you plan your finances effectively.
How Fixed Deposit Calculators Work?
To use a Fixed Deposit Calculator, you need to input three main parameters:
- Principal Amount: This is the initial investment you make in the FD.
- Interest Rate: The rate at which the bank or financial institution will pay interest on your deposit
- Tenure: The period for which you agree to keep your money locked in the FD. This could range from a few months to several years.
Based on these inputs, the calculator gives you the following output.
- Maturity value
- Interest earned
Fixed Deposit Calculator Formula
The general formula used to calculate the maturity value of a Fixed Deposit is:
Where:
- M = Maturity amount (Principal + Interest)
- P = Principal amount (Initial deposit)
- R = Annual interest rate (in %)
- n = Number of times interest is compounded per year
- t = Tenure of the FD (in years)
