Reading Your Paycheck: Where the Money Goes Before You See It
By Hadeed Ahmed Awan · Last reviewed November 2026 · 5 min read
An offer letter quotes an annual salary. Your bank account sees something noticeably smaller, every two weeks. The gap isn't a mistake, but the reasons are scattered across a pay stub in abbreviations that don't explain themselves.
Start with gross pay
Take a $75,000 salary paid every two weeks, which is 26 paychecks a year. Gross pay per check is $75,000 ÷ 26 = $2,884.62. Everything that follows comes out of that figure. If you're paid twice a month instead, it's 24 checks and a slightly larger gross amount each time, though the annual totals work out the same.
Payroll taxes come first and don't bend
Social Security takes 6.2% of your pay, which is $178.85 on this check. Medicare takes 1.45%, another $41.83. Together that's the 7.65% you'll see labeled FICA, $220.67 here. These percentages don't depend on your filing status or your W-4. Social Security stops applying once your earnings pass an annual cap that the Social Security Administration adjusts each year, which most people never reach. Your employer pays a matching amount on top, and it never appears on your stub.
Your 401(k) lowers income tax, not payroll tax
Say you put 5% into a traditional 401(k). That's $144.23 per check. It reduces the income your federal income tax is calculated on, but Social Security and Medicare are still taken from the full gross amount, so the $220.67 above doesn't shrink. A Roth 401(k) works the other way around: it doesn't lower your income tax now, in exchange for tax-free withdrawals later. The 401(k) calculator shows what these contributions add up to over time.
Federal income tax is the part that varies
This is the line people can least predict, because it depends on your W-4 and on everything else in your tax situation. As a rough illustration, assume a single filer taking the 2026 standard deduction of $16,100. Start with $75,000, subtract the $3,750 you put into the 401(k) over the year and the $16,100 deduction, and you have about $55,150 of taxable income. Run that through the 2026 brackets and the federal tax comes to about $6,845 for the year, or roughly $263.27 per paycheck. The income tax calculator will do the same for your own taxable income.
Putting it together
Gross pay of $2,884.62, minus $220.67 for Social Security and Medicare, minus $144.23 for the 401(k), minus $263.27 for federal income tax, leaves about $2,256.44 per paycheck. That's roughly 78% of gross. Health insurance premiums, state and local income tax and any other deductions come out of that as well, so a real take-home figure is often lower, sometimes by a few hundred dollars a month. The paycheck calculator and the take-home pay calculator let you plug in your own deductions.
Withholding isn't the same as what you owe
What your employer withholds is an estimate built from your W-4. At tax time it's compared with what you actually owe, and the difference becomes your refund or your bill. A large refund means you lent the government money, interest-free, all year. A bill means too little was withheld. If either one surprises you, updating your W-4 is how you fix it.
Two months a year feel richer
Biweekly pay means 26 checks, but there are only 12 months, so two months each year contain three paychecks. Budget from the 26-check total rather than from a three-check month, or you'll end up planning around money that doesn't arrive every month.
