Early Withdrawal Penalty Calculator: Check the Exceptions First
Before you count the penalty, check the exceptions. Some apply to 401(k)-type plans only, some to IRAs only, and several have dollar limits. (IRS: exceptions to tax on early distributions)
| Exception | 401(k) | IRA | Limit |
|---|---|---|---|
| Left job in or after the year you turned 55 | Yes | No | — |
| Disability or terminal illness | Yes | Yes | — |
| Substantially equal periodic payments | Yes | Yes | — |
| Medical bills above 7.5% of AGI | Yes | Yes | the excess |
| Emergency personal expense | Yes | Yes | $1,000 a year |
| Birth or adoption | Yes | Yes | $5,000 per child |
| Domestic abuse victim | Yes | Yes | $10,000 or 50% |
| Federally declared disaster | Yes | Yes | $22,000 |
| First home | No | Yes | $10,000 lifetime |
| Higher education | No | Yes | — |

What does an early withdrawal really cost?
Add the penalty to your income tax. A $25,000 withdrawal for someone in the 22% bracket costs $2,500 in penalty and about $5,500 in federal tax — $8,000, or 32%, before any state tax. The calculator works it out from your own income.
Better options to check first
A 401(k) loan avoids tax and penalty if you repay on schedule — generally up to the lesser of $50,000 or half your vested balance. If you've already left the job at 55 or later, the Rule of 55 may cover you, and the withdrawal tax calculator shows what you'd keep (IRS Topic 413).

Our take: the penalty is the smallest cost
Ten percent hurts, but the bigger losses are the tax and the decades of growth that money won't have. Use early withdrawals for real emergencies, and test what's left with the how long will my money last calculator.
