How to Read Your Paycheck: A Complete Paystub Guide Using a Paycheck Calculator

Why You Should Know How to Read Your Paycheck

Most workers glance at the net pay figure on their paycheck and ignore everything above it. That is a mistake. Your pay stub contains dozens of numbers — gross wages, tax withholdings, benefit deductions, year-to-date totals — and errors in any one of them can cost you hundreds of dollars over the course of a year.

Learning to read your paycheck puts you in a position to catch mistakes, verify that your employer is withholding the correct amount, and plan your budget with precision. When you combine pay stub literacy with a paycheck calculator, you can independently verify that every dollar withheld matches what the law and your benefit elections require.

This guide walks through every section of a standard 2026 pay stub, explains what each line means, and shows you how to cross-check the numbers using a paycheck calculator so you never overpay — or underpay — another dollar.

The Anatomy of a Paycheck: Section by Section

Every pay stub follows a similar structure, though the exact layout varies by employer and payroll provider (ADP, Paychex, Gusto, Workday, etc.). Here is the standard order of information:

Header Information

The top of your pay stub identifies the basic parameters of the payment:

• Pay period: The date range this paycheck covers (e.g., June 15 – June 28, 2026)
• Pay date: The date the paycheck is issued or deposited
• Employee name and ID: Your name and internal employee number
• Employer name and address: Your company's legal name and location
• Check number or direct deposit reference: Unique identifier for this payment

If any of these are wrong — especially the pay period dates — the entire paycheck calculation could be off. Verify these first.

Section 1: Gross Wages

This is your total earnings before anything is removed. It appears in several sub-lines:

• Regular hours: Hours worked at your standard rate, typically up to 40 per week
• Regular pay: Regular hours times your hourly rate, or your salary divided by pay periods
• Overtime hours: Hours over 40 per week (or over 8 per day in California), paid at 1.5x your regular rate
• Overtime pay: Overtime hours times 1.5x your rate
• Other earnings: Bonuses, commissions, shift differentials, holiday pay, or retroactive pay adjustments

The sum of all these lines is your gross pay for the pay period. For salaried employees, this is simply your annual salary divided by the number of pay periods. For hourly workers, it is the total of all hourly and overtime earnings.

Verification tip: Use a paycheck calculator to enter your hourly rate and hours worked. The gross pay figure should match what appears on your stub. If it does not, ask your payroll department to explain the discrepancy.

Section 2: Pre-Tax Deductions

Pre-tax deductions are subtracted from your gross pay before income tax is calculated. Because they reduce your taxable income, they lower your federal and state tax bill. Standard pre-tax deductions on a 2026 pay stub include:

• 401(k) or 403(b): Your retirement contribution. If you elected 6% and your gross pay is $2,500, this line shows $150.00. Year-to-date totals accumulate across paychecks.
• Traditional 401(v) or other retirement plans: Some employers offer supplemental retirement accounts.
• Medical insurance: Your share of the premium for employer-sponsored health insurance. This is typically a fixed amount per pay period.
• Dental and vision insurance: Separate lines for dental and vision premiums if they are itemized.
• Health Savings Account (HSA): Contributions to your HSA, up to the 2026 limit of $4,300 (individual) or $8,550 (family).
• Medical Flexible Spending Account (FSA): Up to $3,300 in 2026 for qualified medical expenses.
• Dependent Care FSA: Up to $5,000 per household in 2026 for childcare expenses.
• Commuter benefits: Transit and parking pre-tax contributions, up to $315/month each in 2026.

The total of all pre-tax deductions is subtracted from gross pay to produce your taxable income — the amount subject to federal and state income tax.

Verification tip: Compare your 401(k) deduction on the stub to your elected percentage. If you signed up for 5% but the stub shows 3%, the error compounds over 26 paychecks into a significant under-contribution. Run the numbers through a paycheck calculator with your actual deduction amounts to confirm the taxable income figure is correct.

Section 3: Tax Withholdings

This section breaks down every tax removed from your paycheck. These are the lines that most people ignore — and where the most costly errors occur:

Federal Income Tax

Federal income tax is calculated using Wage Bracket or Percentage Method tables published by the IRS each year. The withholding depends on three factors:

• Your taxable income (gross pay minus pre-tax deductions, annualized)
• Your filing status (single, married filing jointly, married filing separately, head of household)
• Withholding adjustments on your W-4 form (Step 3 for dependents, Step 4 for other income or deductions)

A paycheck calculator that uses 2026 tax brackets and your specific filing status will predict your federal withholding within a few dollars of your actual stub. If the number on your stub is significantly different, your W-4 may need updating.

Social Security Tax

Social Security tax is 6.2% of your gross wages, applied from the first dollar up to the 2026 wage base limit of $176,100. If you earn less than this threshold, your Social Security withholding is exactly 6.2% of gross pay. If you earn more, the withholding stops once your year-to-date earnings reach $176,100.

Employers are required to withhold 6.2% even if you have multiple jobs that individually stay below the cap but collectively exceed it. If you overpay Social Security across multiple employers, you claim the excess as a credit on your tax return — but your employer will not automatically adjust it.

Medicare Tax

Medicare tax is 1.45% of all gross wages with no wage base limit. High earners — those with wages above $200,000 (single) or $250,000 (married filing jointly) — pay an additional 0.9% Medicare surtax on wages above that threshold. Your employer withholds the additional 0.9% once your year-to-date earnings cross the threshold.

State Income Tax

State income tax withholding varies significantly by state. Nine states (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming) have no personal income tax, so this line will be blank. The remaining 41 states plus D.C. withhold according to their own rate schedules, many of which mirror the federal system with state-specific brackets and standard deductions.

Some states have unique withholding rules. Pennsylvania uses a flat 3.07% rate on all wages. Ohio uses a progressive bracket system with rates that exceeded 3.5% for most earners in 2026. California withholds based on its own tax tables, which do not perfectly match federal brackets.

Verification tip: Our state-by-state income tax calculator shows the exact withholding rates for every state. Compare your stub's state tax line to the calculator's output for your income level.

Local Income Tax

Some cities and counties impose their own income taxes. The most common local income taxes in 2026 include:

• New York City: 3.078% to 3.876% progressive rate, depending on income
• Philadelphia: 3.75% wage tax for city residents
• Detroit: 2.4% city income tax
• Many Ohio cities: Cleveland (2.5%), Columbus (2.5%), Cincinnati (1.8%), and dozens of others
• Pennsylvania municipalities: Most municipalities in Pennsylvania impose an earned income tax of 1% to 2%
• St. Louis and Kansas City, Missouri: 1% earnings tax

A paycheck calculator that includes local tax inputs will produce a net pay figure that accounts for these additional withholdings. Without local tax data, your calculated net pay could be $30 to $100+ too high per paycheck.

Section 4: Post-Tax Deductions

Post-tax deductions are subtracted after all taxes are calculated. Because they do not reduce your taxable income, they provide no tax benefit — they simply reduce your take-home pay. Common post-tax deductions:

• Roth 401(k) contributions: After-tax, but distributions are tax-free in retirement. If you split contributions between traditional and Roth, both lines appear separately.
• Roth IRA contributions: Not typically deducted from payroll, but some employers offer payroll deduction convenience for external Roth IRA funding.
• Union dues: Varies by union and employer, often a percentage of gross pay or a flat per-pay-period amount.
• Wage garnishments: Court-ordered deductions for child support, alimony, unpaid student loans, tax levies, or bankruptcy repayments. Federal law limits garnishment to 25% of disposable earnings or the amount by which weekly wages exceed 30 times the federal minimum wage, whichever is less.
• Charitable contributions: Payroll-deducted giving through your employer's charitable program.
• After-tax life insurance: Coverage exceeding $50,000 in employer-sponsored group term life insurance is taxable and appears as a post-tax deduction.
• Disability insurance: Short-term and long-term disability premiums may be pre-tax or post-tax depending on how the plan is structured.

Verification tip: Post-tax deductions should match the elections you made during onboarding or open enrollment. If you see a deduction you did not authorize — especially union dues or charitable contributions you did not sign up for — raise it with HR immediately.

Section 5: Net Pay (Take-Home Pay)

The final line on your pay stub is your net pay — the amount deposited into your bank account or printed on your check. This is the bottom line that all previous sections converge toward.

The formula:

Net Pay = Gross Pay − Pre-Tax Deductions − Federal Tax − Social Security − Medicare − State Tax − Local Tax − Post-Tax Deductions

A paycheck calculator runs this exact formula and returns the same figure. If your calculator output differs from your actual net pay by more than a few dollars, work backward through each section to identify where the discrepancy lies. Common causes: incorrect wage base assumptions (e.g., calculator assumes no Social Security cap when you have reached it), wrong filing status, or missing local tax.

Section 6: Year-to-Date Totals

Most stubs include a year-to-date (YTD) column alongside the current pay period figures. YTD totals show the cumulative amount for each line since January 1 (or your hire date, if later). These totals are critical for:

• Verifying Social Security wage base: Once YTD gross exceeds $176,100, Social Security withholding should stop for the remainder of the year.
• Tracking 401(k) contributions: Ensure YTD contributions are on pace to reach your annual goal without exceeding the $24,500 limit.
• Estimating your tax refund or balance due: YTD federal withholding compared to your projected annual tax liability tells you whether you are on track for a refund or a bill.
• Flagging mid-year changes: If your withholding rate changed after a W-4 update, the YTD figures will show two distinct rates across the year.

Use a paycheck calculator with your YTD income and YTD withholding figures to project your annual tax situation. This is especially valuable in Q3, when you still have time to adjust withholdings before year-end.

How to Verify Your Paycheck Using a Paycheck Calculator

Now that you understand every line on your pay stub, here is the systematic process for verifying accuracy using a paycheck calculator:

Step 1: Enter Your Gross Pay

Enter your hourly rate or salary and your pay frequency. The calculator should produce a gross pay figure that matches your stub. If it does not, verify your hours or salary rate.

Step 2: Enter Your Filing Status and Allowances

Select your filing status (single, married filing jointly, head of household) and enter any W-4 adjustments (dependents, other income, extra withholding). The calculator's federal tax output should be within $5 to $15 of your actual withholding.

Step 3: Enter Pre-Tax Deductions

Enter your 401(k) contribution rate, HSA amount, health insurance premium, and any other pre-tax deductions that appear on your stub. The calculator's taxable income should match your employer's calculation.

Step 4: Select Your State and Local Jurisdiction

Choose your state of employment. If your city has an income tax, enter that separately. The calculator's state tax output should match your stub's state and local tax lines.

Step 5: Compare Net Pay

The final comparison: your calculator's net pay should match your stub's net pay within $5 to $10 for most employees. Larger discrepancies indicate a missing deduction, incorrect rate, or payroll error that warrants follow-up with your employer.

Our free paycheck calculator walks through all five steps in under 60 seconds. Enter your numbers side-by-side with your pay stub and flag any difference larger than $10.

Common Paycheck Errors Found Using a Paycheck Calculator

When workers finally run their numbers through a paycheck calculator, these are the most frequent errors they discover:

Error 1: Incorrect Withholding After a W-4 Change

If you submitted a new W-4 during open enrollment (adding a child, changing from single to married, adjusting withholdings) and your paycheck did not change as expected, the W-4 may not have been processed. A paycheck calculator shows what your withholding should be — if the actual number is off by more than $20 per check, follow up with payroll.

Error 2: Wrong State Tax Rate

Employers are required to withhold state tax based on your state of residence, not necessarily your state of employment. If you live in one state and work in another, your employer should withhold for the correct state. A paycheck calculator lets you run both states' rates to see which one matches your stub.

Error 3: Missed Social Security Wage Base Cap

If your year-to-date gross pay exceeds $176,100 and your employer continues to withhold Social Security tax, you are overpaying by 6.2% on every dollar above the cap. This error is not uncommon in payroll systems that do not automatically stop withholding at the wage base. Over-withheld Social Security is recoverable as a tax credit, but only if you catch it before filing.

Error 4: 401(k) Contribution Rate Not Applied

You elected 6% during enrollment, but your stub shows 0%. This often happens when new-hire paperwork is not processed before the first payroll run. A paycheck calculator showing deductions you would have received at 6% quantifies the loss — both in retirement savings and in the tax deduction you missed.

Error 5: Pre-Tax Benefits Taxed as Post-Tax

Health insurance premiums, HSA contributions, and FSA contributions should be pre-tax. If your stub shows them as post-tax deductions (or omits them entirely from the taxable income calculation), you are paying more in taxes than necessary. Compare your stub to a paycheck calculator output where benefits are correctly classified as pre-tax.

Paycheck Frequency and How It Affects Your Pay Stub

Your pay frequency determines how many paychecks you receive per year and how the withholding is calculated per check:

• Weekly (52 pay periods): Smallest per-check amounts. Withholding is calculated on a per-week basis using IRS weekly tables. Annual totals match other frequencies.
• Biweekly (26 pay periods): Most common for hourly workers. Withholding per check is higher than weekly or semimonthly because the IRS annualizes each biweekly check at a higher rate.
• Semimonthly (24 pay periods): Common for salaried employees. Paid on fixed dates (1st and 15th, or 15th and last day). Per-check withholding is lower than biweekly because the annualization factor is lower.
• Monthly (12 pay periods): Largest per-check amounts. Less common in the United States but typical for some government and academic positions.
• Daily: Rare. Typically used for temporary or seasonal workers paid at the end of each shift.

A paycheck calculator that lets you switch between pay frequencies shows you the exact per-check difference. Your annual net pay is the same regardless of frequency — only the per-check size changes.

Our biweekly pay calculator guide covers the specific withholding implications of biweekly pay, which is the frequency most likely to cause confusion because two months per year have three pay periods instead of two.

Special Paycheck Situations

Not every pay stub is straightforward. Here are common situations that complicate your paycheck reading:

Supplemental Wages (Bonuses and Commissions)

Bonuses and commissions are supplemental wages. Employers can withhold federal tax at a flat 22% (for supplemental wages under $1 million) instead of using your regular W-4 withholding. This means your bonus paycheck will have a higher federal withholding percentage than your regular paycheck even though your actual tax bracket is the same.

Some employers use the aggregate method instead, adding the bonus to your regular paycheck and calculating withholding on the combined amount. This typically produces even higher withholding in the pay period but corrects at filing time. A paycheck calculator with a bonus input method shows you the real take-home from a bonus payment.

Stock Options and RSUs

If you receive restricted stock units (RSUs) or exercise stock options, the taxable income appears on your pay stub as a supplemental income line. RSUs are taxed as ordinary income at vesting, and the withholding rate is typically 22% federal plus FICA and state tax. This can reduce your net pay for the vesting pay period even though you did not receive cash income.

Reimbursements and Per Diems

Accountable plan reimbursements (mileage, travel, equipment) are not taxable income and should not appear in your gross wages. If they do, you may be paying taxes on money that should be tax-free. Verify that reimbursements are listed as separate non-taxable lines on your stub.

Final Paycheck (Severance and Payout)

Your final paycheck may include PTO payout, severance, and any deferred compensation. State laws determine when your employer must deliver your final check — in California, it is immediately upon termination; in most states, it is the next regular pay date. Severance is supplemental wages subject to the 22% flat withholding rate.

Paycheck Calculator FAQ: Reading Your Pay Stub

How do I know if my employer withheld too much federal tax?

Compare your YTD federal withholding to the annual federal tax a paycheck calculator projects for your income level. If your YTD withholding is 10% to 15% higher than your projected annual liability, you are over-withholding and should file a new W-4 to reduce it.

Why is my paycheck smaller after a raise?

A raise can bump you into a higher federal bracket, increase your effective state rate, and — if you are near the Social Security cap — trigger the additional Medicare surtax. A paycheck calculator modeling your new income shows you whether the raise actually reduced your take-home (possible in rare edge cases with benefit phase-outs) or if another factor caused the decrease.

Why do I have two state tax lines on my paycheck?

If you live in one state and work in another, your employer may withhold for both states. You typically receive a credit in your home state for taxes paid to the work state, but the withholding still appears. A paycheck calculator lets you enter both states to see the combined impact.

Can an employer change my withholdings without notice?

Employers must withhold based on the W-4 on file. If your W-4 changed but you did not submit a new one, your employer must continue using your existing W-4. If your withholding changed without explanation, check whether the payroll system applied an updated wage bracket table (IRS tables change annually in January) or whether there was a data entry error.

How does a paycheck calculator handle promotions mid-year?

Enter your new salary or hourly rate as the current rate. The paycheck calculator projects based on current income, not year-to-date average. For a more accurate YTD projection, add your pre-promotion earnings and post-promotion earnings separately, then divide by the number of remaining pay periods.

Verify Every Paycheck in 60 Seconds

Reading your paycheck is not a one-time exercise — it is a habit that pays for itself every pay period. Errors happen. Payroll systems glitch. HR misprocesses W-4s. Tax tables change and employers miss the update. Each of these errors costs you real money that you will not see unless you look.

The combination of pay stub literacy and an accurate paycheck calculator gives you the tools to catch every error, verify every withholding, and ensure that your take-home pay matches what the math says it should be.

Our free paycheck calculator is updated for 2026 across all 50 states. Enter your numbers alongside your pay stub and verify that every line adds up. If something does not match, you will know — and you will know exactly where to look.
