How to use Investment Calculator

Add the account starting point and the planned contribution schedule, and the calculator will estimate how compounding may build the portfolio over time.

What this calculator is for

This calculator is for long-term investing, savings goal planning, and comparing what happens when time, return, or contribution size changes. It is a planning model rather than a promise of actual market performance.

Tips

Separate what you can control, such as contribution size, from what you cannot control, such as annual return, when you compare scenarios.
If contributions happen monthly, use a compounding pattern that is consistent with the way the account is actually funded.
