A pay stub looks like a wall of abbreviations and numbers most people never decode. But buried in there is the full story of where your money goes — and checking it can catch errors that quietly cost you. Once you know what each section means, your pay stub goes from confusing to genuinely useful. Here’s how to read it, line by line.
The three main sections
Almost every pay stub has the same three parts:
1. Gross pay — what you earned before anything is taken out.
2. Deductions — taxes and other amounts subtracted.
3. Net pay — what’s left and actually deposited (your take-home).
Get those three and you understand 90% of any pay stub. The difference between gross and net is the heart of it — we cover that fully in Gross vs Net Pay.
Section 1: Earnings (gross pay)
At the top you’ll usually see your earnings — your salary or hourly rate times hours, plus any overtime, bonuses, or commissions for this pay period. You’ll often see two columns: “current” (this paycheck) and “YTD” (year-to-date, the running total for the year). The YTD numbers are handy for tracking your income and checking your taxes mid-year.
Section 2: Taxes withheld
Next come the taxes taken out. Common labels:
| Label (may vary) | What it is |
|---|---|
| Fed / FIT / Federal | Federal income tax withheld |
| FICA / SS / OASDI | Social Security tax (6.2%) |
| Medicare / MED | Medicare tax (1.45%) |
| State / SIT | State income tax (if your state has one) |
| Local | City or local tax (some areas) |
Together, Social Security and Medicare make up FICA (7.65%). Federal and state income tax amounts depend on your income and your W-4 choices. If these seem way off, it may be time to check your withholding.
Section 3: Other deductions
Beyond taxes, you may see pre-tax and post-tax deductions. Pre-tax deductions (traditional 401(k), health insurance premiums, HSA, FSA) lower your taxable income. Post-tax deductions (Roth 401(k), some benefits, union dues, garnishments) come out after tax. Pre-tax deductions are worth understanding — they reduce your net pay, but they also lower your tax and fund your future, so a smaller take-home isn’t always a loss; sometimes it’s you paying yourself first.
Section 4: Net pay
Finally, net pay — gross minus all taxes and deductions. This is the number that actually hits your bank account, and the one you should build your budget around. You’ll usually see the current net and the YTD net.
Why you should actually check it
Reading your pay stub isn’t just academic — it catches real problems: wrong hours or pay rate (easy to miss, costs you money), incorrect withholding (too little means an April tax bill; too much means an interest-free loan to the government), missing or wrong deductions (a 401(k) contribution that didn’t go through, or a benefit you’re paying for but not using), and benefit changes you didn’t authorize. A two-minute check each pay period can save real money. The U.S. Department of Labor has guidance on pay and recordkeeping at dol.gov.
Use your pay stub for a tax checkup
Your YTD figures are perfect for a mid-year check: compare your YTD federal withholding against your estimated full-year tax. If they’re far apart, adjust your W-4. The Take-Home Pay Calculator and Income Tax Estimator help you sanity-check, and we walk through it in Mid-Year Tax Checkup.
Frequently asked questions
What does YTD mean on a pay stub?
Year-to-date — the running total of that item (earnings, taxes, deductions) for the year so far. It’s useful for tracking income and checking your taxes.
What’s the difference between FICA, Social Security, and Medicare?
FICA is the combined 7.65% payroll tax: 6.2% Social Security (sometimes labeled OASDI) plus 1.45% Medicare. They’re often listed as separate lines.
Why is my net pay so much lower than my gross?
Federal and state income tax, FICA, and pre-tax deductions like 401(k) and health insurance all come out of gross to get to net. See Gross vs Net Pay.
Why should I check my pay stub?
To catch errors — wrong hours, incorrect withholding, missing 401(k) contributions, or unauthorized deductions — that can quietly cost you money.
The takeaway
A pay stub has three core parts: gross pay, deductions (taxes and benefits), and net pay — plus handy YTD totals. Learn the common labels (FICA, Fed, Medicare, state), understand that pre-tax deductions lower both your take-home and your tax, and check it regularly for errors. Use the YTD numbers for a quick tax checkup with the Take-Home Pay Calculator, and budget from your net pay, not your gross.
