How FD Interest is Calculated
Fixed Deposit (FD) maturity amount is calculated using the compound interest formula:
FD Maturity = P × (1 + r/n)nt
Where:
- P = Principal amount (Initial deposit)
- r = Annual interest rate (in decimal)
- n = Compounding frequency (monthly, quarterly, half-yearly, yearly)
- t = Tenure in years
This formula helps calculate the FD maturity value and total interest earned over time. It applies to all types of bank fixed deposits.
