The first paycheck is a shock for almost everyone. The number on the offer letter is gross pay, and it's not what lands in your account. What lands is net pay, after taxes and deductions. Knowing what each line means is the difference between budgeting on a guess and budgeting on a number.
The top: gross pay
Gross pay is your salary divided by the number of paychecks in a year. At $54,000 a year paid every two weeks (26 paychecks), gross pay is about $2,077 per check. Paid twice a month (24 paychecks), it's $2,250. Same salary, different check size, so check your pay schedule before you build a budget around one paycheck.
Pre-tax deductions
These come out before income tax is figured, which lowers the pay that gets taxed.
- Traditional 401(k) or 403(b): what you chose to save for retirement. It lowers income tax, but you still pay Social Security and Medicare on it.
- Health, dental and vision premiums: your share of insurance. When your employer runs these through a cafeteria plan (most do), they lower both income tax and Social Security and Medicare.
- HSA or FSA: money set aside for medical costs, also pre-tax.
Taxes
| Line on the stub | What it is | 2026 rate |
|---|---|---|
| Federal income tax (FIT, Fed W/H) | Withholding based on your W-4 and taxable pay | Depends on income and your W-4 |
| Social Security (OASDI, FICA-SS) | Funds Social Security | 6.2% of wages up to $184,500 |
| Medicare (FICA-Med) | Funds Medicare | 1.45% of all wages |
| State income tax (SIT) | Your state's income tax, if it has one | Varies by state; some have none |
| Local tax | City or county tax in some places | Varies |
Social Security and Medicare together are 7.65% of most new grads' pay. On a $2,077 check that's about $159 before anything else.
Post-tax deductions
Roth 401(k) contributions, some life or disability insurance, and union dues come out after tax. They don't lower your tax bill.
The bottom: net pay and year-to-date
Net pay is what hits your bank account. YTD (year to date) columns add up everything so far this year. Use YTD to check that your 401(k) is on pace and, in December, to sanity-check what your W-2 will show.
Do this with your first stub: divide net pay by gross pay. For many new grads it lands somewhere around 70-80%. Use your real number, not a guess, in the rent calculator.
Three things to check on every stub for the first few months
- Your 401(k) percentage is what you elected. Payroll mistakes happen, and missed contributions are hard to make up.
- You're only paying for benefits you picked. A plan tier you didn't choose (family instead of employee-only) can cost hundreds a month.
- Federal withholding looks right. If almost nothing is being withheld, check your W-4. Under-withholding means a tax bill in April.
Questions
Why is my first paycheck smaller than I expected?
Your offer is gross pay. Federal and state income tax, 7.65% for Social Security and Medicare, and anything you elected (401(k), health insurance, HSA) come out before the deposit. Some first paychecks are also partial because they only cover the days you worked in that pay period.
What is OASDI on my pay stub?
OASDI stands for Old-Age, Survivors and Disability Insurance, which is Social Security. In 2026 it's 6.2% of wages up to $184,500.
Does my 401(k) contribution lower my Social Security tax?
No. A traditional 401(k) lowers federal (and usually state) income tax, but Social Security and Medicare are still taken on that money. Health premiums paid through a cafeteria plan do lower all three.
What should I do if my withholding looks wrong?
Submit a new W-4 to payroll. The IRS has a free Tax Withholding Estimator that tells you what to put on it. Fixing it early beats a surprise tax bill in April.
