How the estimate works

FV = P × (1 + i)ⁿ + A × [((1 + i)ⁿ − 1) / i]

P is the starting amount, A is the monthly contribution, i is the equivalent monthly rate, and n is the number of months. Contributions are added at each month’s end.

This is a mathematical simulation. It does not include taxes, fees or inflation, and does not guarantee returns.
