How this calculator works
Each monthly RD deposit earns compound interest from the month of deposit until maturity. Earlier deposits earn more interest because they stay invested longer.
Maturity = Σ [P × (1 + r/n)^(n × t_i)]
P = Monthly deposit
r = Annual rate (decimal)
n = 4 (quarterly compounding)
t_i = remaining time for deposit i (in years)- Enter the monthly deposit amount.
- Enter the annual interest rate.
- Set the tenure in months.
- The calculator sums compound interest on each monthly deposit for its remaining tenure.
- Results show maturity amount, total invested, and total interest earned.
