How Compound Interest Works

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. The formula used is: A = P(1 + r/n)^(nt) + PMT * [((1 + r/n)^(nt) - 1) / (r/n)].

Where:
• A = Future Value
• P = Principal (Initial Investment)
• r = Annual Interest Rate
• n = Compounding Frequency
• t = Time in Years
• PMT = Monthly Contribution
