If you’ve ever looked at your pay stub and wondered where a third of your salary disappeared to, you’re not alone. Learning how to read your paycheck is one of the most practical money skills you can build: it shows you exactly what you earn, what gets taken out in taxes and deductions, and what actually lands in your bank account.

In this guide, we’ll walk through every section of a standard pay stub line by line — gross pay, pre-tax deductions, federal and state taxes, post-tax deductions, and the employer contributions most people never notice. By the end, you’ll be able to read any paycheck with confidence and calculate your real take-home pay.

Gross Pay vs. Net Pay: The Two Numbers That Matter

Every pay stub revolves around two figures. Gross pay is your total earnings for the pay period before a single deduction: salary or hourly wages, overtime, bonuses, and commissions all count. Net pay — also called take-home pay — is what’s left after taxes and deductions, and it’s the number that actually hits your checking account.

For example, a $65,000 salary paid biweekly means $2,500 in gross pay per check ($65,000 ÷ 26 pay periods). But after federal tax, Social Security, Medicare, state tax, and deductions, the net deposit might be closer to $1,800. That gap is exactly what we’re about to decode — and it’s why budgeting should always be based on net pay, never gross. If you’re building your safety net, our guide on how much emergency fund to save uses take-home pay as its starting point for the same reason.

The Anatomy of a Pay Stub, Section by Section

Pay stub layouts vary by employer and payroll provider, but they all contain the same building blocks. Here’s what to look for from top to bottom.

Header: Who, When, and How Often

The top of the stub identifies you (name, employee ID, sometimes the last four digits of your SSN), your employer, the pay period start and end dates, the pay date, and your pay frequency (weekly, biweekly, semimonthly, or monthly). Check the dates first — being paid for the wrong period is one of the most common payroll errors.

Earnings: How Your Gross Pay Adds Up

This section lists every source of pay for the period: regular hours multiplied by your rate, overtime (usually 1.5× your regular rate for hours over 40 per week), bonuses, commissions, and payouts for vacation or sick time. Next to the current-period column you’ll usually see a YTD (year-to-date) column showing cumulative totals since January 1st — useful for tracking your progress and spotting discrepancies early.

Pre-Tax Deductions: Money That Lowers Your Taxable Income

Pre-tax deductions are subtracted from your gross pay before income taxes are calculated, which means you pay tax on a smaller number. Common ones include:

• Traditional 401(k) contributions — retirement savings that reduce today’s taxable income. If you’re deciding how much to contribute, see our guide on how much to save for retirement.
• Health, dental, and vision insurance premiums (your share of the cost)
• HSA contributions (Health Savings Account, if you have a high-deductible plan)
• FSA contributions (Flexible Spending Account for health care or dependent care)
• Pre-tax commuter or transit benefits

Because these lower your taxable income, $200 per paycheck into a traditional 401(k) doesn’t reduce your take-home pay by the full $200 — it reduces it by $200 minus the tax you would have paid on that $200.

Taxes Withheld From Your Paycheck

Taxes are usually the biggest slice taken from gross pay. Here’s what each line means:

• Federal income tax — withheld based on the W-4 form you filled out when hired and the IRS withholding tables. Note this is an estimate: your actual tax bill is settled when you file your return, which is why you get a refund or owe a balance in April.
• Social Security tax — a flat 6.2% of your earnings up to the annual Social Security wage base, a cap that the government adjusts each year.
• Medicare tax — 1.45% of all earnings, with no cap, plus an additional 0.9% on earnings above $200,000.
• State and local income taxes — these vary widely. A handful of states have no income tax at all, while others (plus some cities) withhold their own share.

All together, it’s normal for combined taxes to take roughly 20–30% of gross pay for a typical earner, though your exact percentage depends on income, location, and W-4 settings.

Post-Tax Deductions: Taken From What’s Left

Post-tax deductions come out after taxes are calculated, so they don’t reduce your taxable income. Typical examples:

• Roth 401(k) contributions — you pay tax now so withdrawals in retirement are tax-free. Not sure which is right for you? Compare both in our Roth vs. Traditional guide.
• Life and disability insurance premiums (supplemental coverage beyond what your employer provides)
• Union dues or professional association fees
• Charitable contributions via payroll
• Wage garnishments — court-ordered deductions for debts, child support, or back taxes

The Hidden Paycheck: What Your Employer Pays for You

One section that never appears on your stub — but should change how you think about your compensation — is what your employer pays on top of your salary:

• Employer payroll taxes: your employer matches your 6.2% Social Security and 1.45% Medicare contributions dollar for dollar — another 7.65% of your pay.
• 401(k) match: many employers match part of your retirement contributions (a common formula is 50% of your contributions up to 6% of salary). That’s free money added to your total compensation.
• Unemployment insurance and workers’ compensation premiums.

Add it up and a $65,000 salary typically costs an employer around $75,000 once payroll taxes and benefits are included. Your true compensation is meaningfully bigger than your gross pay.

How to Calculate Your Take-Home Pay

The math behind your paycheck follows one simple formula:

Gross pay − pre-tax deductions − taxes − post-tax deductions = net (take-home) pay

5 Paycheck Mistakes to Avoid

1. Never reviewing your stub. Wrong hours, an outdated pay rate, or a missing bonus are surprisingly common — and they only get fixed if you spot them. Scan every stub, at least the YTD column.
2. Getting your W-4 wrong. A big tax refund feels nice, but it means you gave the government an interest-free loan all year. Too little withholding means an unpleasant bill in April. Revisit your W-4 after major life changes.
3. Budgeting on gross pay instead of net. Your $5,400/month salary isn’t $5,400 of spending money. Lenders look at gross income (that’s why your debt-to-income ratio uses it), but your budget must run on take-home pay.
4. Ignoring the YTD column. Year-to-date totals are your early-warning system: they reveal whether withholding, 401(k) contributions, and HSA deposits are on track for the year.
5. Not re-checking after life changes. Marriage, a new baby, a move to a new state, a raise, or a second job can all change your withholding needs. A two-minute stub review after any of these beats a surprise at tax time.

Paycheck FAQs

Why is my paycheck less than my salary divided by pay periods?

Dividing your salary by the number of pay periods gives your gross pay per check. Your actual deposit is lower because federal income tax, Social Security, Medicare, state taxes, and any benefit or retirement deductions are subtracted first. The remainder is your net or take-home pay.

What does YTD mean on a pay stub?

YTD stands for “year-to-date” — the running total of your earnings, taxes, and deductions from January 1st through the current pay period. It’s the fastest way to verify your annual 401(k) contributions, tax withholding, and total earnings are on track.

What percentage of my paycheck goes to taxes?

For a typical US earner, combined taxes (federal income, Social Security, Medicare, plus state/local) take roughly 20–30% of gross pay. Your exact share depends on your income level, filing status, state, and W-4 withholding elections.

What’s the difference between pre-tax and post-tax deductions?

Pre-tax deductions (traditional 401(k), health premiums, HSA) are subtracted before income tax is calculated, lowering your taxable income. Post-tax deductions (Roth 401(k), life insurance, union dues) come out after taxes and don’t reduce what you’re taxed on.

Should I change my W-4 if I get a big tax refund?

A consistently large refund means you’re over-withholding — essentially lending the IRS money interest-free. Adjusting your W-4 to reduce withholding puts more in each paycheck instead. Use the IRS Tax Withholding Estimator to dial it in, especially after marriage, a new child, or a job change.

How can I tell if my paycheck has an error?

Compare the stub against your records: verify the pay period dates, your hours and rate (or salary amount), overtime calculations, and that deductions match your elections. Check the YTD column for anything that looks off versus previous stubs, and confirm your W-4 elections are reflected in the federal withholding line.

The Bottom Line

Your paycheck tells a complete story — gross earnings, the taxes that fund Social Security and Medicare, the deductions building your retirement and health coverage, and the employer’s hidden contributions on top. Once you know how to read your paycheck, you can catch costly errors, fine-tune your withholding, and budget with your real numbers instead of guesses.
