Results explained

The headline is estimated net cash after ordinary tax sketches and, if applicable, the 10% additional tax on early distributions. Employers may withhold differently than your eventual tax — this is a planning net, not a paycheck stub.

Quick reference: early 401(k) withdrawal

Traditional 401(k) pre-tax dollars are generally taxable as ordinary income when withdrawn.

How the estimate is built

Net = amount − (amount × fed%) − (amount × state%) − (amount × 10% if age < 59½ and no exception).

Example scenario

$25,000 at age 45 with 22% federal and 5% state and no exception → taxes $6,750 + penalty $2,500 → about $15,750 net (37% effective friction).

FAQ

Is withholding the same as tax?

No. Plans often withhold a flat federal percent; your return true-ups the bill.

Roth 401(k)?

Qualified Roth withdrawals can be tax-free; early nonqualified withdrawals have different basis ordering. This page models taxable traditional-style withdrawals.

Loan instead?

A 401(k) loan is a different product — not modeled here.
