401(k) Calculator

See how your contributions, employer match and time can work together to build retirement savings, and how small changes today may add up over the long term.

A 401(k) can be one of your best tools for creating a secure retirement. It provides you with two important advantages. First, all contributions and earnings to your 401(k) are tax-deferred. You only pay taxes on contributions and earnings when the money is withdrawn. Second, many employers provide matching contributions to your 401(k) account.
