Quick answer: Your paycheck starts with gross pay, subtracts pre-tax deductions (401(k), health insurance), then federal income tax, Social Security and Medicare, and any state tax to get net pay. For a $78,000 salary paid every two weeks (26 checks), gross pay is $3,000 and take-home is about $2,204 with 6% to a 401(k) and $150 of health premiums per paycheck.
The numbers on a pay stub are not hard once you know the order: gross pay, pre-tax deductions, taxes, after-tax deductions, net pay. This guide uses an example so you can follow the math, then lists common errors to check.

Frequently asked questions
What is the difference between gross pay and net pay?
Gross pay is your total earnings before deductions. Net pay, or take-home, is what remains after taxes and deductions.
Why is my paycheck smaller than my salary divided by pay periods?
Income tax, FICA, retirement contributions and benefit premiums are subtracted.
What are pre-tax deductions?
Amounts taken out before income tax is calculated, such as traditional 401(k) contributions and health insurance premiums.
What does YTD mean on a pay stub?
Year-to-date: the running total of earnings, taxes and deductions for the calendar year.
Why does my first paycheck of the year look larger?
Some employers pay taxes progressively, or Social Security tax stops after the wage base for high earners, increasing later paychecks.
