$60,000 salary, paid monthly: $382.50 goes to Social Security and Medicare
Gross pay isn't take-home pay
$60,000 ÷ 12 is $5,000 a month, before anything is withheld. Our fictional single filer is paid monthly in tax year 2026, with no other income.

Social Security and Medicare: a flat 7.65%
Social Security takes 6.2% ($310.00) and Medicare takes 1.45% ($72.50). Together, called FICA, that's 7.65%, or $382.50 of the $5,000.
The math: $5,000 × 7.65% = $382.50

Income tax withholding, figured separately
For a single filer paid monthly with a 2020+ W-4 and Step 2 unchecked, Pub 15-T gives $418.33 a month, figured on the full $5,000. That matches the tax on $43,900 taxable ($60,000 − $16,100 standard deduction).
The math: $1,240 + $3,780 = $5,020 a year; ÷ 12 = $418.33

Where the first $5,000 goes
Out of $5,000, $382.50 goes to FICA and $418.33 to federal withholding. That leaves $4,199.17 before state tax and benefits.
The math: $5,000 − $382.50 − $418.33 = $4,199.17

A 401(k) lowers only one of them
A 5% pre-tax 401(k) is $250 a month. It lowers federal withholding $30 to $388.33 (state withholding may fall too), but FICA stays $382.50 because deferrals are still wages for it.
The math: $250 − $30 = $220

When this example stops applying
State and local income tax and benefits vary. In 2026, Social Security stops after $184,500 of wages, and an extra 0.9% Medicare is withheld over $200,000. A different W-4 or pay frequency changes withholding.

Match your own pay stub
Find gross pay on your stub, then the Social Security and Medicare lines. They're usually 6.2% and 1.45% of your Social Security/Medicare wages, which can be below gross if health premiums or an FSA/HSA come out pre-tax.

Assumptions:
- Fictional single filer, $60,000 annual salary, paid monthly (12 equal paychecks of $5,000)
- Tax year 2026, federal only; no state or local income tax shown
- No other income, no dependents, standard deduction; 2020-or-later Form W-4 with nothing entered beyond filing status (Step 2 not checked)
- No pre-tax benefits in the base case; the 401(k) example assumes a 5% traditional pre-tax deferral ($250/month, $3,000/year) and no other changes
- Withholding computed with the IRS Pub 15-T 2026 annual percentage method; actual payroll systems may round differently by a few cents
The short version
- $5,000 gross, and $382.50 goes to FICA
- Federal withholding was $418.33 a month (Pub 15-T method)
- A pre-tax 401(k) lowers only income tax withholding
- Take-home fell $220, not $250 (federal only)
