What Is a Fixed Deposit (FD)?
A Fixed Deposit is an investment where you deposit a lump sum amount for a fixed period at a guaranteed interest rate. The bank pays interest either monthly, quarterly, half-yearly, or annually, depending on the FD type. The return is predictable, making FD a preferred option for low-risk investors.
FDs are widely used for:
- Safe Investments with no market risk
- Long-term savings for goals like education or retirement
- Emergency Funds with partial withdrawal options
- Tax-saving investments (5-year tax saver FD)
If you prefer monthly investment instead of lump sum, use SIP Calculator.
How FD Return Is Calculated
FD interest depends on four key factors:
- Principal Amount (Deposit amount)
- Interest Rate (Offered by bank/NBFC)
- Tenure (Months or years)
- Compounding Frequency (Monthly, Quarterly, Annually)
The formula for FD maturity with compounding is:
A = P (1 + r/n)n×t
- A = Maturity Amount
- P = Principal
- r = Annual interest rate
- n = Compounding frequency
- t = Time in years
Our calculator applies this formula instantly to give accurate results.
FD Compounding Frequency
Banks offer different compounding options:
- Monthly Compounding: Interest grows every month
- Quarterly Compounding: Most common in banks
- Half-Yearly Compounding
- Annual Compounding
Higher compounding frequency generally yields higher maturity value.
