Quick Answer
Your paycheck is lower than your hourly rate times hours because of mandatory deductions like taxes (typically 15-25% of gross pay), Social Security (6.2%), Medicare (1.45%), and voluntary deductions like health insurance or 401(k) contributions that can reduce take-home pay by another 5-15%.

Why your paycheck is smaller than expected
Your gross pay (hourly rate × hours) gets reduced by several mandatory and voluntary deductions before you receive your take-home pay. According to IRS Publication 15-T, employers must withhold federal income tax, Social Security tax (6.2%), and Medicare tax (1.45%) from every paycheck.
The difference can be substantial. If you earn $20/hour and work 40 hours, your gross pay is $800. But your actual paycheck might only be $600-650 after all deductions.
Example: $20/hour employee working 40 hours
Let's break down a typical biweekly paycheck:
Your $1,600 gross becomes $1,046 net — a reduction of $554 or about 35%.

How tax withholding works
Your employer uses your W-4 form and IRS withholding tables to estimate your annual tax liability, then spreads that amount across your paychecks. The withholding might be too much or too little — that's why you get a refund or owe money when filing your tax return.
What affects your take-home percentage
What you should do
Use our paycheck calculator to see exactly how much you'll take home based on your specific situation. Input your hourly rate, hours, state, and benefit deductions to get an accurate estimate. If your actual paycheck differs significantly from the calculation, review your pay stub line by line or use our paystub explainer tool.
Key takeaway: Your take-home pay is typically 65-80% of your gross pay due to taxes (15-25%) and voluntary deductions (5-15%). A $20/hour job yields about $13-16/hour in actual take-home pay.
Key Takeaway: Your take-home pay is typically 65-80% of gross pay, with taxes taking 15-25% and voluntary deductions like health insurance and 401(k) reducing it by another 5-15%.

Perfect for new workers experiencing payroll deductions for the first time
Welcome to the working world — here's what's happening to your paycheck
If this is your first job, the difference between what you expected and what you received can be shocking. Don't worry — this is completely normal, and understanding it will help you budget better.
The biggest surprise: taxes
Even at entry-level wages, you'll lose about 15-20% of your gross pay to taxes. If you make $15/hour:
That's $126-191 less than your gross pay — every single week.
Why this happens
Your employer is required by law to withhold taxes from your paycheck and send them to the government on your behalf. This is called "pay-as-you-go" taxation. Without it, you'd owe a huge tax bill when filing your return.
Entry-level budgeting tip
When job hunting, don't budget based on gross pay. If a job pays $30,000/year, plan your budget around $22,000-25,000 take-home. Use the 70% rule: your take-home will be roughly 70% of your gross salary at entry-level wages.
What about benefits?
Many entry-level jobs offer health insurance, which might cost you $50-150 per paycheck. While this reduces your take-home pay, it's usually a good deal — individual health insurance can cost $300-600/month.
Key takeaway: Plan your budget around 70% of your gross pay. A $15/hour job provides about $10.50/hour in actual spending money after taxes and basic deductions.
Key Takeaway: For first-time workers, budget around 70% of your gross pay. A $15/hour job typically provides about $10.50/hour in actual take-home pay after taxes.

Best for workers juggling multiple part-time jobs or a side hustle
Multiple jobs create withholding complications
When you have multiple jobs, each employer withholds taxes as if it's your only job. This often results in under-withholding, meaning you might owe money at tax time instead of getting a refund.
Example: Two part-time jobs
Job A: $12/hour, 25 hours/week = $15,600/year
Job B: $15/hour, 20 hours/week = $15,600/year
Combined income: $31,200/year
Each employer withholds taxes assuming you're in the 12% bracket. But combined, you're actually earning enough to push some income into higher brackets, plus you lose some standard deduction benefits.
What typically happens
Solutions for multiple job holders
1. Update your W-4: Use the IRS Tax Withholding Estimator to determine if you need extra withholding
2. Have extra withheld: Ask one employer to withhold an additional $50-100 per paycheck
3. Make quarterly payments: If you're significantly under-withheld, make estimated tax payments
4. Consider the side hustle carefully: If your second job is freelance work, you'll owe self-employment tax too
The 1099 side hustle difference
If one of your "jobs" is actually freelance work (you get a 1099), that income has NO taxes withheld. You'll owe both income tax AND self-employment tax (15.3%) on that money.
Key takeaway: Multiple jobs often result in under-withholding. Use the IRS Tax Withholding Estimator to avoid owing money at tax time, especially if your combined income exceeds $30,000.
Key Takeaway: Multiple job holders often under-withhold taxes because each employer treats their job as if it's your only income. This frequently results in owing money at tax time.
