Payroll software is great at taking money out and terrible at explaining where it went. If you’ve ever looked at your check and thought “wait, that’s it?”, you’re not bad with money — nobody ever walked you through the document. This guide reads a pay stub line by line, so you know exactly what you earned, what got taken out, why, and whether the math is even right.
First, where to even find it
Most employers don’t hand you paper anymore. Your stub lives in a payroll portal — ADP, Workday, Gusto, Paychex or similar — usually under “Pay,” “Earnings,” or “Pay statements.” If you get direct deposit, the stub is the itemized receipt for that deposit.

The one idea that clears up everything
A pay stub has two numbers that matter most: gross pay (what you earned) and net pay (what actually hits your account). Everything in between is a deduction. Read it top to bottom and it stops being a wall of numbers and starts being a simple subtraction problem.
Start with your gross pay
This is the top line — your total earnings before anything is taken out. If you’re hourly, check that it equals your rate × hours, and that overtime shows up at 1.5× for hours over 40 in a week. If you’re salaried, it should be your annual salary divided by the number of pay periods in the year.
That last part trips people up, so know your pay frequency: weekly is 52 checks a year, biweekly is 26 (every other Friday), semimonthly is 24 (e.g. the 15th and the last day), and monthly is 12. A “$60,000 salary” paid biweekly is about $2,308 gross per check — not $2,500 — because 26 doesn’t divide as neatly as it feels like it should.
Find the taxes — the deductions you can’t avoid
These come out by law, on every check:
• Federal income tax — based on the W-4 you filled out when you were hired.
• State income tax — unless you live in a no-income-tax state (Texas, Florida, Washington, Nevada and a few others).
• FICA — this is Social Security (6.2%) + Medicare (1.45%), totaling 7.65% of your pay. It usually shows as two separate lines, sometimes labeled “OASDI” and “Med.”
FICA is not the same as income tax, and it isn’t optional. If you ever switch to 1099 (independent contractor), you pay both halves — 15.3% — because there’s no employer covering the other half. That surprise is what sinks a lot of first-time freelancers who forgot to set money aside.
Read the “other deductions” — where money quietly disappears
These are the ones you opted into (or got auto-enrolled in): health insurance premiums, 401(k) retirement contributions, HSA or FSA, dental and vision, life insurance, and union dues.
Look at whether each is pre-tax or post-tax. Pre-tax deductions (your 401(k), most health premiums, HSA) come out before taxes are calculated, which lowers your taxable income — a good thing. Post-tax deductions come out after. Your stub labels this, though not always loudly.
If you ever see a line for a garnishment — child support, a court judgment, or defaulted federal debt — that’s a legal order your employer must follow. It’s rare, but if it appears and you don’t recognize it, contact HR the same day.
Learn the two columns: Current vs. YTD
Nearly every stub shows two amounts for each line: “Current” (this paycheck) and “YTD” (year-to-date, the running total since January 1). The YTD column is the one people ignore and shouldn’t — it’s how you confirm your total income for a loan application, and how you catch a deduction that’s been wrong for months instead of just this once.
Land on your net pay
Gross pay − all deductions = net pay, a.k.a. your take-home. This is the number that should match your bank deposit to the penny. If it doesn’t match, something’s off — and now you know exactly which lines to check.
A pay advance is not a raise. If your employer fronted you money, it gets deducted from a later check — sometimes under a vague label. Compare stubs and make sure an advance isn’t being pulled out twice.
How to catch an error in under a minute
Payroll mistakes are common, and they’re almost always honest system errors rather than anything sinister — but they cost you real money. Run this four-point check every few stubs:
• Hours — do they match what you actually worked, including overtime and any holiday pay?
• State — is tax withheld for the correct state? This matters a lot if you moved or work remote across state lines.
• A deduction you didn’t authorize — a benefit you dropped that’s still being charged.
• The same deduction twice — duplicates love to appear right after a company switches payroll providers.
Found something? Email payroll with the specific pay date and the exact line in question. Keep it in writing — a paper trail gets errors fixed faster than a hallway conversation.
Gross is what you earned, net is what you keep, and the gap is taxes (federal, state, FICA) plus the benefits you signed up for. Read a stub top to bottom one time, learn to glance at the YTD column, and you’ll never be blindsided by a paycheck again.
Quick questions
Why is so much taken out?
For most workers, taxes alone run 20–30% of gross before any benefits. FICA (7.65%) is fixed; income tax depends on your W-4 and your state. If it feels like too much, your W-4 may be set to withhold extra — you can adjust it with HR.
Gross vs. net — which one is my “real” salary?
A job offer of “$60,000” means gross. Your net is what you actually budget with — usually 70–80% of gross depending on your state and the benefits you elected.
My net pay dropped but my rate didn’t change. Why?
Usual suspects: a new benefit enrollment (open enrollment just passed), a bonus check pushing you briefly into higher withholding, or a W-4 change. Put this stub next to last month’s and compare the deductions line by line — the culprit almost always jumps out.
Do I need to keep old pay stubs?
Keep at least the last few, plus your final stub of the year (its YTD totals should match your W-2). Landlords and lenders routinely ask for your two most recent stubs as proof of income.
