FD Maturity Value
Fixed Deposit (FD) maturity is calculated using the compound interest formula:
Maturity = P × (1 + r/n)^(n × t)
Where:
- P = Principal (deposit amount)
- r = Annual interest rate (as decimal)
- n = Compounding frequency per year
- t = Tenure in years
Interest earned = Maturity - Principal
Compounding frequency options:
- Quarterly (n=4): Most common for bank FDs
- Monthly (n=12): Some banks offer this
- Half-yearly (n=2): Less common
- Yearly (n=1): Simple annual compounding
Example: $100,000 at 7% for 5 years (quarterly compounding):
- Maturity: $141,478
- Interest earned: $41,478
Higher compounding frequency yields slightly more interest, but the difference narrows over short tenures.
