401(k) vs take-home pay (2026)
Sample take-home: $60,859.58 a year · $5,071.63 a month · $2,340.75 biweekly.
Tax year 2026, California, single, standard deduction, no 401(k).
A traditional 401(k) deferral lowers federal (and usually state) taxable wages, so income tax withholding falls — but Social Security and Medicare generally still apply to the deferred amount. Below is the same $80,000 California single sample at 0% and 10% using the Takehome Cash engine.

Ten percent of $80,000 is $8,000 deferred. That money is still yours in the plan; it is not “tax” on this page. Net take-home drops by less than $8,000 because federal and California tax are computed on the remaining wages. FICA is almost unchanged if you have no cafeteria-plan health premium.
Roth 401(k) is not modeled: Roth deferrals do not reduce federal wages. Employer match does not appear on the employee stub as cash, so it is omitted. Annual IRS elective-deferral limits can cap a high-percent election; we do not enforce the dollar cap in v1.
The calculator starts at 10% so you can drag the percent toward zero and watch federal and state lines move. Health premiums (section 125) reduce FICA as well as income tax — a different lever than 401(k). Estimates only, reviewed October 2, 2026.

FAQ
Does a 401(k) reduce Social Security tax?
Usually no. Traditional elective deferrals stay in the Social Security and Medicare wage base. Pre-tax health premiums under a cafeteria plan generally reduce FICA wages.
What sample is shown?
$80,000 annual, California, single, 0% vs 10% traditional 401(k), no health premium, no extra withholding.
Is the 10% contribution gone?
It is withheld from the check and sent to the plan. This page reports cash take-home, not total compensation.
