Investment Estimator
A simple compound interest calculator. Estimate how much your investment can grow over time with regular contributions.
How compound interest works
Compound interest means the returns you earn start earning returns of their own. A balance growing at 10% a year does not add the same amount each year; it adds 10% of an ever larger total, which is why long time horizons matter far more than the starting amount.
Enter a starting amount, how many years you plan to invest, the annual return you expect and any regular contributions. The chart shows your projected balance year by year, split into what you put in and what the growth added.
Growth projection
Estimate your investment growth at an assumed annual return
Projections assume a constant annual return and do not account for inflation, taxes or fees.
