Rule of 55 Calculator

The Rule of 55 is an IRS provision that lets you take money from your current employer's 401(k) or 403(b) without the usual 10% early-withdrawal penalty, as long as you leave that job in or after the calendar year you turn 55. Normally, withdrawals before age 59 1/2 trigger a 10% penalty on top of income tax. The Rule of 55 waives that penalty for the plan tied to the job you just left. It comes from Section 72(t)(2)(A)(v) of the tax code.

You qualify if you separate from service (quit, are laid off, or retire) during or after the calendar year in which you turn 55. The test uses the calendar year, not your exact birthday, so leaving in January of the year you turn 55 still counts. The withdrawal must come from the 401(k) or 403(b) at the employer you just left. This calculator compares the year you leave your job with the year you turn 55 and gives you a clear yes or no.

No. The Rule of 55 only applies to a 401(k) or 403(b) at the employer you separated from. It never applies to IRAs, and if you roll your old plan into an IRA you lose the exception and must wait until age 59 1/2. It also does not cover 401(k) plans left at earlier employers, unless you rolled those into your current plan before you left.

Certain qualified public-safety employees can qualify after separation in or after the year they reach age 50, or after 25 years of service under the plan, whichever is earlier. This calculator models only the age-50 path. It cannot determine whether your job and plan qualify or whether you meet the service-year path, so confirm both with your plan administrator or tax professional.

Yes. The Rule of 55 only removes the 10% early-withdrawal penalty. Distributions from a traditional pre-tax 401(k) or 403(b) are still taxed as ordinary income in the year you take them, which can push you into a higher bracket. The calculator applies the marginal tax rate you enter so you can see the estimated income tax and the net cash you keep.

No. This tool gives an estimate for planning, not financial or tax advice. It applies the single marginal income tax rate you enter, so include state tax in that rate if it applies, and it does not model mandatory 20% withholding or plan-specific rules. Confirm the details with your plan administrator and a tax professional before withdrawing.
