Your Paycheck Is Smaller Than Your Salary. Here Is Exactly Why.
Bottom line
On a $55,000 salary, you might only take home $38,000 after taxes and deductions.

What it is
Your pay stub is a line by line breakdown of where your gross pay (the full amount you earned before anything is removed) goes before the remainder lands in your bank account.
By the numbers
On a $55,000 salary, your gross paycheck every two weeks is about $2,115. After federal income tax ($253), FICA taxes ($162), state income tax ($63), a 401k contribution ($106), and health insurance ($85), your take home pay is roughly $1,446. That is $669 gone before you see a cent.
How it works
Your employer splits your gross pay into deductions before sending you the rest. FICA (Federal Insurance Contributions Act) takes 7.65% automatically to fund Social Security and Medicare. Federal and state income taxes are withheld based on your W-4 form (the document you fill out when hired that tells your employer how much tax to hold back).
The catch
Pre tax deductions like your 401k contributions and health insurance premiums are subtracted before your taxable income is calculated. That means putting $200 per paycheck into a 401k does not actually reduce your take home pay by $200. It reduces it by closer to $150 because you avoid paying income tax on that $200.
Why it matters
If you get a $5,000 raise, you will not take home $5,000 more per year. Taxes and FICA will absorb roughly $1,500 to $1,800 of it. Knowing this prevents the very common mistake of spending a raise before you understand how much of it you actually keep.
FAQ
What does FICA mean on my pay stub?
FICA stands for the Federal Insurance Contributions Act. It covers two separate deductions: Social Security (6.2% of wages up to $176,100 in 2025) and Medicare (1.45% of all wages, with an extra 0.9% on wages above $200,000). Your employer matches these amounts, so the total FICA tax is 15.3% and you pay half.
What are pre-tax deductions and how do they save me money?
Pre-tax deductions — like 401(k) contributions, health insurance premiums, and FSA/HSA contributions — are subtracted from your gross pay before taxes are calculated. If you contribute $200/month to your 401(k) and you are in the 22% federal bracket, you effectively save $44/month in federal income tax alone, plus the Social Security and Medicare savings on top.
Why does my take-home pay change when I get a raise?
A raise increases your gross pay, which may push some of your income into a higher marginal tax bracket and slightly increases your FICA base. If your raise moves you past a bracket threshold, only the new dollars above the line get taxed at the higher rate — the rest stays the same. Your take-home still goes up, just not by the full raise amount.
