How this calculator works

Withdrawals are taxed as ordinary income at your federal bracket and state rate, and before age 59½ a 10% penalty usually applies. What's left is the cash you keep. The calculator also shows what the full amount could grow to if left invested until retirement.

Worked example

With the example values below: Cash you keep, $12,600 (63% of the withdrawal). Change any number above to run your own.
