Getting paid is one of the most rewarding parts of working. Understanding exactly where the money went is another matter.
A pay stub is the itemized record behind every deposit: what you earned, what was withheld, what you paid for, and what was left over. Learning to read one takes only a few minutes, but the skill can be useful throughout your career.
For women building careers in technology, pay stub literacy matters more than it might first appear. Tech compensation is rarely limited to salary. Base pay, annual or spot bonuses, equity that vests on a schedule, employer retirement contributions, health coverage, and paid leave can all combine into a compensation package that no single number in a job offer fully captures.
Your pay stub is one place where many of those pieces become visible in practice.
A note on scope: This article covers U.S. payroll practices. Payroll rules, tax rates, and the information employers provide on pay statements vary by country and, in some cases, by state. Readers working outside the United States can check the requirements that apply where they are employed.
Why Pay Stub Literacy Matters in a Tech Career
A promotion from $90,000 to $100,000 sounds like roughly $833 more each month before taxes and deductions. The increase that reaches your bank account will usually be smaller.
Federal and state withholding may change along with higher wages. A percentage-based retirement contribution can automatically increase, and benefit elections may affect the amount deducted from each paycheck.
None of that necessarily signals a problem. It reflects the difference between what you earn and what you receive.
Understanding that difference can help you evaluate raises, job offers, and compensation packages more accurately. WomenTech Network's guide to navigating salary negotiations in tech explores the market-value side of that conversation: what your skills are worth and how to approach compensation discussions. Your pay stub helps you understand what those numbers look like once an offer, raise, or promotion takes effect.
For women in technology who may be comparing salary, equity, flexibility, retirement benefits, and other parts of a total compensation package, that context can make compensation decisions more informed.

Start With Gross Pay
Gross pay is the total amount you earned during the pay period before taxes and other deductions are withheld. Everything else on the pay stub is calculated from or deducted from this amount.
For salaried employees, regular gross pay is generally based on the annual salary divided across the employer's pay periods.
For example, someone earning $120,000 on a semimonthly schedule of 24 paychecks would have $5,000 in regular gross earnings per full pay period.
For hourly employees, gross pay is typically based on the hourly rate multiplied by hours worked. Overtime, on-call pay, commissions, bonuses, and other forms of compensation may appear as separate earnings lines.
Check this figure carefully on the first paycheck after a salary change. Compare the salary and effective date in your promotion or compensation letter with what appears on the pay stub.
Changes that take effect in the middle of a payroll cycle are particularly useful moments to review the calculation because part of the period may have been paid at the previous rate.
Check the Pay Period and the Pay Date
The pay period is the range of dates for which you earned the wages shown.
The pay date is the date the payment was issued.
They are not necessarily the same. That distinction can explain why a raise that takes effect at the beginning of a month does not appear until a later paycheck.
These dates become especially important when compensation changes partway through a payroll cycle. If an increase takes effect halfway through a two-week period, for example, the paycheck may contain earnings calculated at both the old and new rates.
Use the pay-period dates to compare overtime, paid leave, commissions, bonuses, and other variable compensation against your own records.
Read the Tax Withholding Lines
Taxes usually account for a significant portion of the difference between gross pay and net pay.
Federal income tax withholding is based in part on the information provided to your employer on Form W-4 and the federal withholding methods published by the IRS.
If federal withholding consistently appears much higher or lower than expected, the IRS Tax Withholding Estimator can help you review whether updating Form W-4 may be appropriate.
A year involving a major salary increase, bonus, second job, or other meaningful income change can be a useful time to review withholding.
Social Security and Medicare
Social Security and Medicare taxes normally appear as separate lines, sometimes grouped under FICA.
For most employees, the employee Social Security tax rate is 6.2% on covered wages up to the annual Social Security wage base. Medicare tax generally applies at 1.45%, while an Additional Medicare Tax can apply after wages exceed the applicable threshold.
Because the Social Security wage base changes over time, higher-paid employees may notice that Social Security withholding stops once their covered year-to-date wages reach that year's limit.
That can cause take-home pay to increase later in the year without any change to salary.
State and Local Taxes
State and local income tax withholding depends on where you live and work.
This is particularly worth checking after moving or beginning remote work across state lines. Payroll withholding does not always change automatically when an employee's work location changes.
Remember that payroll withholding is not necessarily the same as your final tax liability. Your tax return reconciles the amount withheld during the year with the amount ultimately owed or refunded.
Look at Deductions and Benefits
Taxes are only part of the difference between gross and net pay. The rest often comes from benefit elections and other deductions.
Common pay-stub deductions include:
Health, dental, and vision insurance premiums
Retirement plan contributions such as a 401(k) or 403(b)
Health savings account or flexible spending account contributions
Life and disability insurance
Employee stock purchase plan contributions
Union dues, wage garnishments, or other authorized deductions
Two categories deserve particular attention.
Retirement Contributions
Retirement contributions reduce the amount available in today's paycheck while moving money toward long-term savings.
If your employer provides a matching contribution, reviewing your pay statement or benefits portal can help confirm that your own contribution is being recorded at the percentage you selected.
If something appears inconsistent with your election, check the plan documents or contact payroll or your benefits team.
Pre-Tax Benefits
Some deductions can reduce the wages subject to certain taxes.
That is one reason two employees with the same salary can have different taxable wages, withholding, and net pay.
Benefit elections, retirement contributions, filing information, and other factors can all affect the final amount deposited.

Find Your Net Pay
Net pay is the amount remaining after taxes and deductions are taken from gross earnings. It is often called take-home pay.
For example:
Gross pay: $7,500
Taxes: $2,108
Other deductions: $789
Net pay: $4,603
Net pay is generally the most useful number for understanding how much money is available for day-to-day budgeting.
It is less useful as the only measure for comparing job offers.
A role with a strong retirement match, employer-paid health coverage, meaningful equity, generous paid leave, or other benefits may provide greater overall value even if the amount arriving in each paycheck is lower than expected.
For women evaluating opportunities in technology, looking beyond base salary can be especially important when comparing roles with different mixes of cash compensation, equity, benefits, and career-growth potential.
Track Bonuses, Commissions, and Equity
Technology compensation often includes components that do not appear on every paycheck, and these can make pay statements harder to interpret.
Bonuses and Supplemental Wages
Bonuses may be treated as supplemental wages for federal withholding purposes.
Depending on how the payment is made and how the employer calculates withholding, a bonus may have federal income tax withheld differently from a regular paycheck. The IRS explains the rules for supplemental wages in Publication 15.
That is why the amount deposited from a bonus can be considerably lower than the headline bonus amount.
Withholding is not necessarily the same as the final tax owed on that income. The difference is reconciled when the employee files a tax return.
Equity Compensation
Vesting equity can create another surprise.
When restricted stock units vest, their value may be treated as taxable compensation. Depending on the employer's plan and payroll process, the value can appear in gross earnings while shares or cash are withheld to cover taxes.
As a result, you may see a significant increase in gross pay or year-to-date earnings without a corresponding increase in the amount deposited into your bank account.
Keep your offer letter, promotion memo, bonus plan, and equity grant documents somewhere accessible. When an earnings line looks unfamiliar, those records give you something concrete to compare against the pay statement.
Use the Year-to-Date Totals
The year-to-date, or YTD, columns show cumulative earnings, taxes, and deductions since the beginning of the calendar year.
They can be more informative than looking at a single paycheck in isolation.
YTD figures are useful for:
Confirming that a raise has been reflected across the expected pay periods
Tracking retirement contributions against annual plan limits
Monitoring progress toward the Social Security wage base
Reviewing income information needed for a mortgage, lease, or other financial application
Checking whether withholding appears consistent before the end of the year
Comparing your final year-to-date gross earnings with the compensation you expected for the year can also provide a useful annual review of salary, bonuses, and other payroll-based compensation.
Compare Pay Stubs and Raise Errors Early
One of the simplest ways to spot a payroll issue is to compare your current pay stub with the previous one.
Look for changes in:
Pay rate
Hours worked
Overtime
Benefit deductions
Retirement contribution percentages
Gross pay
Taxes
Net pay
Many changes will have an explanation. A raise, bonus, benefits election, updated tax withholding, or reaching the Social Security wage base can all affect the numbers.
A change you cannot explain is worth investigating.
When contacting payroll or HR, be specific. Identify the exact line, the amount shown, the amount you expected, and the document or benefit election that supports your question.
Putting the request in writing also creates a record of the issue and the response.
If you are still learning what the standard fields look like, a pay stub example can help you become familiar with common sections and terminology. Your employer's official payroll records, however, remain the authoritative source for your own compensation, taxes, employment information, and income verification.
Turn Your Pay Stub Into a Career Tool
You do not need to become a payroll expert.
Instead, build one simple habit: read your pay stub carefully after a promotion, raise, bonus, benefits change, or job move, and review it periodically during the rest of the year.
Ask four questions:
Does my gross pay match my current compensation?
Do the deductions match the benefits and contributions I selected?
Are my retirement contributions being recorded correctly?
Do the year-to-date totals make sense for this point in the year?
Those questions can help identify many common discrepancies while also building a clearer understanding of your total compensation.
That knowledge becomes useful well beyond payroll.
When you know what your salary, benefits, retirement contributions, bonuses, and equity are actually worth, you are in a stronger position to compare opportunities and prepare for your next compensation conversation.
Your pay stub is more than a list of numbers. It is a recurring record of how your work is compensated.
Learning to read it fluently is a small financial skill that can provide value throughout a career in technology.
