How to Read Your First Pay Stub (Every Line Explained)

The first time you look at a pay stub, it’s confusing and kind of depressing. You worked 40 hours at $15/hour, you’re expecting $600, and the actual deposit is like $487. Where did $113 go? Who took it? Why are there so many lines on this thing?

Nobody walks you through this. Your employer hands you access to a pay portal or a paper stub and assumes you know what everything means. You don’t. I didn’t. So here’s the line-by-line breakdown that every teenager with their first job needs.

The top section: what you earned

Gross Pay: This is the total amount you earned before anything gets taken out. If you worked 40 hours at $15/hour, your gross pay is $600. This is the number you calculated in your head and the number you’ll never actually see in your bank account.

Hours Worked / Rate: Most stubs break this down — regular hours, overtime hours (usually 1.5x your normal rate for anything over 40 hours/week), holiday pay if applicable. Check these numbers against your own records. Payroll mistakes happen more often than you’d think, and catching them is your responsibility.

Pay Period: The dates this paycheck covers. Usually biweekly (every two weeks) or semi-monthly (twice a month, like the 1st and 15th). Know your pay schedule so you can plan your budget.

The middle section: what gets taken out (deductions)

This is where the money disappears. There are two types of deductions: mandatory (the government requires them) and voluntary (things you opted into).

Mandatory deductions

Federal Income Tax: The IRS takes a percentage based on how much you earn and what you put on your W-4 form. For most teenagers making $15,000-25,000/year, this is roughly 10% of your taxable pay, but the withholding might be higher or lower depending on your W-4 settings. If you expect to earn less than the standard deduction ($14,600 for 2024), you might have claimed exempt on your W-4, in which case this line is $0.

Social Security Tax (OASDI): 6.2% of your gross pay. Every single paycheck, no exceptions, no deductions to reduce it. On $600 gross, that’s $37.20. This funds Social Security — the retirement program you’ll benefit from decades from now.

Medicare Tax: 1.45% of your gross pay. On $600, that’s $8.70. Funds the Medicare healthcare program. Also no exceptions.

Social Security + Medicare together = FICA: 7.65% total. This is the tax that hits hardest because there’s no way to reduce it — no deduction, no exemption. On every $600 paycheck, $45.90 goes to FICA no matter what.

State Income Tax: Depends on your state. If you’re in Texas, Florida, Nevada, Wyoming, Washington, Alaska, South Dakota, Tennessee, or New Hampshire — congratulations, this line is $0 because those states have no income tax. If you’re in California, New York, or most other states, expect another 3-8% deducted depending on your income level and the state’s rates.

Local/City Tax: Some cities have their own income tax. Not super common but it exists (New York City, some cities in Ohio and Pennsylvania, etc.). Usually small — 1-3%.

Voluntary deductions (these only show up if you opted in)

Health Insurance: If you enrolled in your employer’s health plan, your premium comes out of each paycheck pre-tax. As a teenager on your parents’ insurance (you can stay on theirs until 26), this probably doesn’t apply to you yet.

401(k) / Retirement Contributions: If you set up 401(k) contributions, they come out here. For a traditional 401(k), this reduces your taxable income (you’ll notice your federal tax withholding is lower). For a Roth 401(k), it comes out after tax.

Other Benefits: Dental, vision, life insurance, HSA contributions, commuter benefits — these all show up as deductions if you enrolled.

The bottom section: what you actually get

Net Pay: This is it. This is what actually lands in your bank account. Gross pay minus all deductions equals net pay. This is the real number. Get used to thinking in net pay, not gross, when you’re budgeting.

YTD (Year-to-Date) Totals: Most stubs show cumulative totals for the calendar year — total gross pay, total taxes paid, total deductions. These are useful at tax time and for checking that your annual income is tracking where you expect.

A real example (roughly)

Let’s say you’re a teenager in Colorado, single, no dependents, earning $15/hour and working 30 hours/week, paid biweekly.

Gross Pay (2 weeks): $900.00

Deductions:

• Federal Income Tax: ~$52.00

• Social Security (6.2%): $55.80

• Medicare (1.45%): $13.05

• Colorado State Tax (~3.5%): ~$31.50

Total Deductions: ~$152.35

Net Pay: ~$747.65

You earned $900 but took home $748. About 17% went to various taxes. If you were in a no-income-tax state, you’d keep that extra $31.50, bringing your net to about $779.

Things to actually check on your pay stub

Don’t just glance at the net pay and move on. A few things worth verifying:

Are your hours correct? Compare the hours on the stub to your own records. If you tracked 32 hours but the stub says 28, that’s a mistake — bring it up with your manager or HR immediately. This is the most common payroll error and it directly costs you money.

Is your pay rate correct? Make sure the hourly rate matches what you were told when hired. Especially check this on your first stub.

Are the right deductions being taken? If you claimed exempt on your W-4, federal income tax should be $0. If it’s not, your W-4 wasn’t processed correctly. Same thing in reverse — if you didn’t claim exempt, there should be a federal withholding amount.

Is anything deducted that you didn’t sign up for? Occasionally, employees get auto-enrolled in things they didn’t choose (like supplemental insurance). If you see a deduction you don’t recognize, ask HR what it is.

Watch your YTD totals. As you approach the standard deduction amount in gross income (~$14,600), that’s when federal income tax withholding actually starts mattering. If you’re working summer-only or very part-time, you might earn under the standard deduction for the year and be owed a full refund of any federal tax withheld.

How to use this information

Knowing what’s on your pay stub isn’t just about understanding deductions. It actually helps you make better financial decisions:

Budgeting accuracy. Budget from your NET pay, never your gross. If you calculate your budget based on $900 but only bring home $748, you’re planning to spend money you don’t have.

Tax planning. By watching your YTD earnings, you can estimate your tax situation before the year ends. If you’re approaching the standard deduction limit, you’ll know whether to expect a refund or a bill.

Catching errors. Payroll departments process hundreds or thousands of paychecks. Mistakes happen. You are the best person to catch errors on YOUR stub because you know how many hours you worked and what you agreed to be paid.

Retirement readiness. If you start a job with a 401(k), seeing the actual impact of contributions on your paycheck helps you decide how much to contribute. “6% of my paycheck” feels abstract until you see it’s $54 per paycheck. Then you can decide if you can handle that or need to start lower.

The psychological adjustment

There’s a reason your first paycheck feels like a disappointment. You did the mental math of hours × rate and got excited about a number that doesn’t exist. The gap between gross and net is something every worker deals with, and the emotional adjustment takes a few paychecks.

The good news: once you accept net pay as your real income and budget accordingly, the tax deductions become invisible. You stop thinking about the $152 that “disappears” and start planning around the $748 that actually arrives. That mental shift — planning with real numbers, not theoretical ones — is the foundation of every other financial skill.

And now that you know exactly where every dollar goes, you can start making those dollars work harder. Automate 20% of your net pay into savings and investments, cover your expenses, and spend the rest without stress. That’s the whole system, and it starts with understanding this piece of paper.
