Formula Used

Compound Interest Formula

Future Value = Initial Investment × (1 + Annual Return Rate) ^ Investment Period

This formula calculates the future value of your investment by applying the annual return rate compounded over the investment period.

Worked Example

Let's say you invest $10,000 with an expected annual return of 7% over 10 years.

Example Calculation

Future Value = $10,000 × (1 + 0.07)^10 ≈ $19,671.51

After 10 years, your $10,000 investment would grow to approximately $19,671.51 with a 7% annual return.
