How is compound interest calculated?
The compound interest formula calculates the future value of an investment based on the principal, rate, and compounding frequency. The formula used is:
Where:
A = Final Amount
P = Principal Amount
r = Annual Rate (as decimal)
n = Number of Compounding Periods per Year
t = Time in Years
With Monthly Contributions:
A = P × (1 + r/n)n×t + M × ((1 + r/n)n×t − 1) / (r/n)
