Why use a VOO calculator
A VOO calculator lets you turn a vague question — "should I invest in VOO?" — into a concrete number you can reason about. By adjusting the initial investment, monthly contribution, time horizon, and assumed return, you can see how each factor changes the projected outcome, and compare that against your own goals.

Frequently asked questions
This is an educational calculator, not financial advice.
Results shown are estimated future values based on the return assumption you enter — they are not predictions and VOO is not guaranteed to achieve any particular return. Past performance of the S&P 500 or any fund does not guarantee future results. Consider speaking with a licensed financial professional before making investment decisions.
