Instant answers to "what could my money grow to?" — pick a lump sum or a monthly contribution and a time horizon to see the projected future value at a 7% return, with charts, scenarios and the formula.
These projections use standard future-value math. A lump sum grows by FV = P × (1 + r)n, while regular monthly contributions grow by the annuity formula FV = PMT × [((1 + i)n − 1) ÷ i]. We default to a 7% annual return — close to the long-run historical average of a diversified stock portfolio — and also show 5% and 10% scenarios on each page so you can see a conservative and an optimistic outcome. Real returns vary year to year and are reduced by taxes and fees, so treat every figure as a planning illustration rather than a guarantee. For a fully custom projection with your own rate, contributions and inflation adjustment, use the investment calculator or the compound interest calculator.
