Compounding Can Really Help Your Savings Add Up

Because earnings in a 401(k) plan compound via market growth, dividends and/or interest, over time your money can grow in an exciting way. In the hypothetical example shown here, you can see how $1,000 could turn into $20,000 over a 40-year career.

This example compares how a one-time investment of $1,000 can grow over time assuming an 8.0% fixed annual rate of return. Your account may earn more or less. This is a hypothetical example only, and not a guarantee of future returns. Actual experience will vary with portfolio selections and changing market conditions. The total account balance does not take into account federal and state income taxes, which will be due upon withdrawal. Assets withdrawn before 59½ may incur a 10% tax penalty.
