The offer letter says $80,000. Your biweekly paycheck says about $2,300. Multiply by 26 pay periods and you land near $60,000 — a full quarter of your salary, gone before you ever touched it. Nothing is wrong. This is simply what a salary costs to become a paycheck.
Where it goes: four buckets
- Federal income tax — progressive, so most earners land at an effective rate around 12–22%. (Marginal brackets confuse everyone; the number that matters is your average.)
- State income tax — anywhere from 0% to 13%+ depending on where you live. Several states take nothing at all.
- FICA — 7.65% off the top for almost everyone: 6.2% Social Security plus 1.45% Medicare. No deductions, no exceptions.
- Pre-tax deductions — 401(k) contributions, health insurance premiums, HSA or FSA money. These shrink your taxable income, which softens the federal and state bite.
How to estimate it in 60 seconds
Take-home ≈ (gross salary − pre-tax deductions) × (1 − federal rate − state rate − 0.0765)
Example: an $80,000 salary with $5,000 going to a 401(k), an 18% federal rate, and 5% state tax → $75,000 × 0.6935 ≈ $52,000 a year, or about $4,335 a month. That is the number your budget should be built on.
Always budget on take-home, never gross
Every budgeting method — the 50/30/20 rule included — runs on money that actually arrives in your account. Planning with gross salary means planning with phantom money, and it's a big reason budgets feel broken by the 15th of the month.
Read your pay stub like a pro
Pull up one pay stub and find three lines: gross pay (the fantasy), deductions (the reality), and net pay (your life). Then glance at the YTD — year-to-date — column, which shows the totals so far this year. Two things to check: that your 401(k) contribution matches what you elected, and that no mystery deduction appeared. Payroll errors are rare but real, and nobody audits your stub but you.
While you're there, note your filing status and allowances. Got married, had a kid, or picked up a side gig this year? Your withholding probably needs a tune-up — the IRS withholding estimator takes ten minutes and prevents an ugly surprise in April.
Quick answers
Why was my first paycheck smaller than I expected?
Benefits elections (health insurance, 401(k)) often start immediately, and partial pay periods prorate oddly. Judge by your third paycheck, not your first.
What exactly is FICA?
The payroll tax that funds Social Security and Medicare: 7.65% of your wages (6.2% + 1.45%). Your employer quietly matches it behind the scenes.
If I get a raise, won't taxes eat all of it?
No — that's the bracket myth. Only the dollars inside a higher bracket are taxed at that higher rate; everything below is taxed exactly as before. A raise always raises your take-home pay.
