About Compound Interest

Compound interest is interest earned on both the principal amount and any previously earned interest. This creates exponential growth over time, making it a powerful tool for long-term investing.

Principal: The initial amount invested
Interest Rate: Annual percentage rate of return
Time Period: Number of years the money is invested
Compounding Frequency: How often interest is calculated and added

Formula: A = P(1 + r/n)^(nt)
Where: A = Final amount, P = Principal, r = Annual rate, n = Compounding frequency, t = Time in years
