A traditional 401(k) withdrawal is taxed as ordinary income, and if you’re under 59½ you usually owe an extra 10% penalty — so a large chunk disappears immediately, plus you lose all future tax-deferred growth on that money. Exceptions (disability, certain medical costs, a first home for IRAs) can waive the penalty. After 73, required minimum distributions (RMDs) begin.
How it’s calculated & sources
Tax = withdrawal × (marginal federal rate + state rate). Penalty = 10% of the withdrawal if under age 59½. You keep = withdrawal − tax − penalty.
Benchmark: the IRS 10% early-withdrawal penalty before age 59½ (with exceptions); RMDs required starting at age 73.

Worked example
A $20,000 withdrawal at age 45 in the 22% bracket loses $4,400 in federal tax plus a $2,000 penalty — you keep about $13,600, or 68%.
Frequently asked questions
How much tax will I pay on a 401(k) withdrawal?
It’s taxed as ordinary income at your marginal rate, plus any state tax, plus a 10% penalty if you’re under 59½.
How do I avoid the 10% penalty?
Wait until 59½, or qualify for an exception (disability, certain medical or hardship rules, a 72(t) plan). A loan or rollover may be better than a withdrawal.
When are RMDs required?
Required minimum distributions from traditional 401(k)s and IRAs currently begin at age 73.
