What a Pay Stub Is — and Why It Matters
A pay stub (sometimes called a pay slip or earnings statement) is the itemized record your employer provides each time you're paid. It accompanies your paycheck or direct deposit and breaks down exactly how your wages were calculated and where deductions went. Many employers make stubs available through an online payroll portal even when there's no paper check.
Reading your pay stub isn't just useful — it's a financial literacy basic. It lets you verify you're being paid correctly, understand your true cost of benefits, and gather accurate income figures for budgeting or loan applications. Once you can decode one stub, you can decode almost any stub, because the structure is largely standardized across employers.
Gross pay
Your total earnings for a pay period before any taxes or deductions are taken out.
Net pay
The amount you actually receive after all taxes and deductions have been subtracted from gross pay.
FICA
Federal Insurance Contributions Act — the law mandating payroll taxes for Social Security and Medicare, split between you and your employer.
Pre-tax deduction
An amount subtracted from your gross pay before income taxes are calculated, reducing the income you're taxed on.
Year-to-date (YTD)
A running total of earnings, taxes, and deductions accumulated from January 1 of the current year through your most recent pay period.
W-4
A form you complete for your employer that tells them how much federal income tax to withhold from each paycheck.
Gross Pay: Your Starting Number
The first major figure you'll see is gross pay — your total earnings for the pay period before a single dollar is withheld. For salaried workers, this is simply the annual salary divided by the number of pay periods (26 for biweekly, 24 for semi-monthly, and so on). For hourly workers, it's the hourly rate multiplied by hours worked, plus any overtime.
Your stub may also itemize earnings types separately — regular pay, overtime, holiday pay, commissions, or bonuses — then add them together to produce the gross pay total. Always confirm this arithmetic matches your own records, especially if your hours fluctuate.
Double-Check Your Hours Each Period
Before you accept your gross pay figure, compare it against any timesheet or scheduling records you keep. Payroll systems occasionally misread punches or forget to include approved overtime. Catching an error on the same stub it occurs is far simpler than correcting it weeks later after payroll has closed.
Taxes Withheld: Federal, State, and FICA
The deductions section is where most of the unfamiliar abbreviations live. Three categories account for the bulk of what's withheld:
- Federal income tax: Withheld based on your gross pay, pay frequency, filing status, and the allowances or adjustments you entered on your W-4 form. This is an estimate of what you'll owe the IRS — not a final number. You'll true it up when you file your annual return. For a deeper look, see our guide on why your paycheck and your tax bill rarely match.
- State (and sometimes local) income tax: Withheld at the rate set by your state or locality. Nine states currently have no individual income tax, so workers there won't see this line.
- FICA taxes: Two separate line items — Social Security and Medicare — that fund those federal programs. Social Security is withheld at 6.2% of wages up to the annual wage base set by the IRS each year. Medicare is withheld at 1.45% on all wages, with an additional 0.9% on wages above $200,000 for individual filers.
Your Employer Pays Half of FICA Too
The Social Security and Medicare amounts shown on your stub represent only your half of the FICA contribution. Your employer pays an identical amount on top of your wages — money you never see on the stub but that goes to the same programs. Self-employed individuals pay both halves themselves, which is why they face a higher self-employment tax rate.
Other Deductions: Benefits and Retirement
Below the tax lines you'll typically find voluntary (and sometimes mandatory) deductions that your employer routes to benefit programs on your behalf:
- Health, dental, and vision insurance premiums
- Your share of the cost for employer-sponsored coverage. These are usually pre-tax deductions under a Section 125 cafeteria plan, meaning they reduce your federally taxable wages.
- 401(k) or 403(b) retirement contributions
- Money directed into your workplace retirement account. Traditional contributions are pre-tax; Roth contributions are post-tax. Both appear as separate line items.
- Flexible Spending Account (FSA) or Health Savings Account (HSA)
- Pre-tax contributions set aside for qualified medical or dependent-care expenses.
- Life and disability insurance
- Employer-sponsored policies where you pay a portion of the premium, often a small flat amount per period.
Once you're comfortable reading your stub, you'll find these deduction figures invaluable for building your first budget, since they clarify the true cost of your benefits package.
Net Pay and Year-to-Date Totals
Net pay is gross pay minus all taxes and deductions. It's the amount deposited into your bank account — your actual take-home pay. If it looks lower than you expected, trace back through each deduction line; the math should add up exactly.
Most stubs include a year-to-date (YTD) column alongside the current-period column. These running totals show cumulative gross earnings, each tax category, and each deduction since January 1. YTD figures are especially useful for:
- Verifying that your annual 401(k) contributions stay within IRS limits.
- Confirming your Social Security withholding stops once you hit the annual wage base.
- Providing accurate income documentation when applying for a loan or lease.
Your W-2 form at year-end will reflect these same YTD totals — so checking them throughout the year is one of the best ways to avoid surprises at tax time. See our companion piece on what your W-2 is actually telling you for how those figures carry forward.
