The first time people see a paycheck, they're often surprised: the amount that lands in their account is noticeably smaller than their salary. The gap between what you earn and what you take home comes down to the difference between gross pay and net pay.
Gross Pay vs. Net Pay
Gross pay is your total earnings before anything is taken out — your salary or your hourly rate times hours worked. Net pay (your “take-home pay”) is what's left after deductions. Net pay is the number that actually matters for budgeting, because it's the money you can spend.
What Gets Deducted
Several things come out of gross pay. Income taxes — federal, and often state — are withheld based on your earnings. FICA taxes fund Social Security and Medicare (about 7.65% of pay). On top of taxes, you may have deductions for health insurance, retirement contributions (like a 401(k)), and other benefits.
Because of all this, your take-home pay is often meaningfully less than your gross — which is exactly why budgeting should be based on net pay.
Withholding and the W-4
When you start a job, you fill out a W-4 form, which tells your employer how much tax to withhold from each paycheck. Withhold too little and you may owe money at tax time; withhold too much and you get a refund — which really just means you loaned the government your money interest-free for the year. The goal is to get it roughly right.
How to Read a Pay Stub
Your pay stub itemizes everything: gross pay, each tax and deduction, and the resulting net pay, usually for both the current pay period and the year to date. Reading it is a good habit — it lets you confirm you're being paid correctly and understand where your money is going before it ever reaches you.
It also connects to a bigger idea: taxes fund public services, and how much you owe depends on your income through a system of tax brackets.
Key Takeaways

- Deductions include income tax, FICA (Social Security + Medicare), and benefits.
