About These Tools
All four calculators are built specifically for the Vanguard S&P 500 ETF (VOO). The investment growth calculator is the simplest — enter a monthly amount and see how your portfolio could grow over time. The past performance calculator is backward-looking — it uses actual historical prices and dividends to show what really happened. The dividend income calculator projects future dividend payouts, and the retirement calculator works backwards from your income goal.
Together, they cover planning, backtesting, income projection, and retirement goals. None of these tools provide investment advice. For more context on the fund itself, see our complete guide to VOO, the VOO and Chill strategy guide, or explore VOO's dividend history and current holdings.
