This Compound Interest calculator will show you the impact of long-term investing, which is essential to wealth accumulation. Fill in the fields below based on your current situation (and contribution amount) to see how much your portfolio will grow over different lengths of time, like 10, 20, or 30 years. Try entering the length of time until you would like to retire and experiment with differing ‘monthly contributions’ until you can get to your goal portfolio size within your goal timeframe. If you are a two-income household, be sure to include both of your contributions. Hint: 8% is a standard Rate of Return for future stock market performance, hence the default. If you disagree, change it to what you expect.

This calculator is not currently compatible with internet explorer, we are working on a fix.
