How Quickly Your IRA or 401(k) Will Grow

Here’s a chart that shows how fast $1 contributed to an IRA or 401(k) plan at the end of each year will grow at various compound interest rates over different periods of time.  You can use this table to determine the value of your IRA or 401(k) plan at a future date.  For example, assume that you contribute $6,000 a year for the next ten years at an 8% average rate of return.  Based on these assumptions, the chart shows that $1 would grow by a factor of 14.4865.  Multiply your $6,000 contribution by that factor to determine that your IRA or 401(k) plan would be worth $86,919.
