How to Read Your Pay Stub Line by Line

You work hard for your paycheck, but you might be surprised by how little of your gross pay actually lands in your bank account. Between federal taxes, state taxes, Social Security, Medicare, and benefits deductions, it's common to take home 65–75% of what you earned. Understanding every line on your pay stub puts you in control of your finances and helps you catch errors that could be costing you money.

The Two Most Important Numbers: Gross Pay vs. Net Pay

Start at the top and bottom of your pay stub:

• Gross Pay: What you earned before any deductions. If you make $25/hour and worked 80 hours this pay period, your gross pay is $2,000.
• Net Pay: What actually hits your bank account after all deductions. This is sometimes called "take-home pay."

The gap between these two numbers is every line item in between. Understanding that gap is what this guide is about.

Your Earnings Section

The earnings section breaks down how your gross pay was calculated. Common line items include:

• Regular Pay: Your base hours at your standard hourly rate (or your salary prorated for the pay period)
• Overtime Pay: Hours worked beyond 40 in a week, paid at 1.5x your regular rate (federal law). Some states have additional overtime rules.
• Holiday Pay: Paid time off for company holidays, if applicable
• PTO/Vacation Pay: Paid time off used during the pay period
• Bonus: Performance bonuses, signing bonuses, or commission payments
• Tips: For service industry workers, declared tip income may appear here

Double-check this section every pay period. Payroll errors happen — especially if you worked overtime or had an unusual pay period. Compare the hours listed against your own records.

Federal Tax Withholding

This is the amount withheld from your paycheck and sent to the IRS on your behalf toward your annual federal income tax bill. How much is withheld depends on your W-4 form — the document you filled out when you were hired.

Your W-4 and Tax Withholding

The W-4 asks how many allowances or adjustments to claim. The more adjustments you claim, the less is withheld each paycheck (meaning a bigger check now but potentially a smaller refund — or a tax bill — in April). Fewer adjustments means more is withheld and you're more likely to get a refund.

Common reasons to update your W-4:

• You got married or divorced
• You had a child (qualifying for Child Tax Credit)
• You got a second job or significant pay increase
• You got a large unexpected tax bill last year

The IRS provides a free Withholding Estimator at irs.gov to help you figure out the right W-4 settings for your situation.

FICA Taxes: Social Security and Medicare

FICA stands for Federal Insurance Contributions Act. These two deductions are mandatory for almost all workers:

• Social Security (6.2%): Withheld on wages up to $168,600 in 2024 (the Social Security wage base — this number adjusts annually). Once you earn above this cap, Social Security withholding stops for the rest of the year.
• Medicare (1.45%): Withheld on all wages with no cap. High earners pay an additional 0.9% Medicare surtax on wages above $200,000 (single) or $250,000 (married filing jointly) — this is handled at tax time, not via payroll.

Your employer matches your FICA contributions — they pay another 6.2% Social Security and 1.45% Medicare on your behalf. This is one reason hiring employees is expensive for companies. You don't see this on your pay stub, but it's a real cost of your employment.

State Income Tax Withholding

If your state has an income tax, you'll see a state withholding line. State tax rates vary enormously — from 0% in states like Texas, Florida, and Nevada (no state income tax) to over 10% in California for high earners. Most states have a flat or graduated rate between 3–7% for middle incomes.

Some states also have local income taxes (cities like New York City, Philadelphia, and some Ohio cities). These appear as separate withholding lines.

Pre-Tax Deductions (The Good Ones)

These deductions reduce your taxable income — meaning you pay taxes on a smaller number, which is a benefit. Common pre-tax deductions:

401(k) or 403(b) Contributions

Your retirement plan contributions come out of your gross pay before income taxes are calculated. If you earn $2,000 gross and contribute $200 to your 401(k), you only pay income taxes on $1,800. This is the government incentivizing you to save for retirement. If your employer matches contributions, that match shows up separately — it's free money.

Health Insurance Premium

Your share of the monthly health insurance premium, typically deducted from each paycheck. If your employer covers 80% and you pay 20%, your 20% is usually a pre-tax deduction — again reducing your taxable income.

HSA Contributions (Health Savings Account)

If you have a high-deductible health plan (HDHP), you may contribute to an HSA pre-tax. HSA contributions are triple tax-advantaged: tax-free contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses.

FSA Contributions (Flexible Spending Account)

Similar to HSA but "use it or lose it" — you must spend FSA funds by the end of the plan year (or a grace period). Also pre-tax.

Dental and Vision Insurance

Often bundled with health insurance or available as separate elections during open enrollment. Usually pre-tax deductions.

Commuter Benefits

Some employers offer pre-tax transit or parking benefits — you pay for your commute with pre-tax dollars, reducing taxable income.

Post-Tax Deductions

These come out after taxes have been calculated, so they don't reduce your tax burden:

• Roth 401(k) contributions: Unlike traditional 401(k), Roth contributions are after-tax (you pay taxes now, not in retirement)
• Life insurance over $50,000: The cost of employer-provided life insurance above $50,000 is a taxable fringe benefit
• Wage garnishments: Court-ordered deductions for child support, student loan default, or debt judgments appear here
• Certain union dues
• Charitable contributions through payroll

Year-to-Date Totals

Most pay stubs show both period amounts (this paycheck) and year-to-date (YTD) totals (everything accumulated since January 1). The YTD totals are useful for:

• Checking whether you're on track to hit the Social Security wage base cap
• Verifying your 401(k) contributions against the annual limit ($23,000 in 2024, $30,500 if you're 50+)
• Cross-referencing with your W-2 at tax time (they should match)

Common Pay Stub Errors to Catch

Payroll errors are more common than most people realize. Here's what to watch for:

• Wrong hours: Compare the hours listed against your own time records
• Overtime not included: If you worked over 40 hours, confirm overtime appears at 1.5x
• Benefits you canceled still being deducted: If you dropped a benefit during open enrollment, verify it stopped
• Wrong state tax: If you moved to a different state or city, confirm withholding was updated
• 401(k) match not appearing: If your employer matches, confirm it's being credited

If you find an error, report it to HR or payroll immediately. Most errors can be corrected in the next pay period.

How Your Pay Stub Helps You Budget

Your net pay is the number that actually matters for budgeting. Building your budget around gross pay is a common mistake that leads to overspending — your gross pay is not money you actually have. Always budget from net pay.

Knowing your pre-tax deductions also reveals the value of your total compensation beyond salary. If your employer contributes $500/month to your health insurance, that's $6,000/year of compensation that doesn't appear in your base salary number — and it's worth factoring in when comparing job offers.

Use Cash Balancer to log your net paycheck and build a budget around what you actually take home. You can track multiple income sources, scan paychecks to log them quickly, and see your monthly cash flow at a glance — so your budget is always grounded in reality, not estimates.

The Bottom Line

Your pay stub is a financial document worth understanding completely. It shows you where your money goes before it reaches you, helps you spot errors that could be costing you real dollars, and gives you the complete picture of your total compensation. Read it every pay period — it takes two minutes and keeps you in control of your income.
