How to use

Enter your recurring contribution amount, cadence, duration, and assumed annual return. The tool updates in real time to show projected end value, total invested, and total gain.

The line chart shows year-by-year growth: the teal line is portfolio value, the grey-blue line is cumulative capital invested. The callout marks the first year when returns exceed your full-year contribution.

FAQ

What people usually want to know

What is dollar-cost averaging?
DCA means investing a fixed amount at regular intervals regardless of price, which reduces the impact of market timing over time.
Does the calculator account for taxes?
No — results show pre-tax growth. Factor in capital gains tax or tax-advantaged account effects separately.
