What if you had invested monthly? Explore market history, test future scenarios and calculate a savings goal for retirement or college. Share the journey as a video.
What if you had invested every month since that year? Explore your own balance through historical market data.
Set a start date, initial amount, monthly contribution and index. See contributions and portfolio value alongside your age and market events. Compare saving choices, explore future assumptions, work back from a goal, and share an animated video. Video sharing and source information are available for free.
Plan for retirement or college savings with a long-term investment simulation. Explore S&P 500 or global equity index scenarios, then work backwards from a savings goal. Account tax benefits and contribution limits are not included.
Some index series are synthetic series derived from index data, not the performance of a real investment product. Results are before tax and exclude taxes and tax advantaged account rules. Projections are uncertain. This app does not provide investment advice.
