Explanation of the Calculation
The calculation uses the compound interest formula:
Future Value = Initial Investment * (1 + (annualRate / 100) / timesCompounded)^(timesCompounded * years)
This formula takes into account the effects of compounding, which means you earn interest on both the initial investment and the accumulated interest over time.
