How This Calculator Works

Investing regularly and letting compound returns work over time is one of the most reliable ways to build wealth. The key variables are: how much you invest, your rate of return, and how long you stay invested. Even modest monthly contributions can grow to significant amounts over 20-30 years thanks to compounding.
