Detailed Breakdown
Understanding Your Paycheck
Your paycheck contains several important components:
- Gross Pay: Your total earnings before any deductions
- Pre-Tax Deductions: 401(k), HSA, health insurance (reduce taxable income)
- Federal Withholding: Estimated federal income tax based on your W-4
- FICA Taxes: Social Security (6.2%) and Medicare (1.45%)
- State Tax: Varies by state
- Post-Tax Deductions: Roth contributions, garnishments
- Net Pay: What you actually receive
Frequently Asked Questions
Paycheck variations can occur due to changes in tax withholdings, benefit elections, overtime pay, bonuses, or adjustments to your W-4. Review your pay stub for specific changes.
Submit a new W-4 form to your employer's HR or payroll department. You can adjust your withholdings anytime to better match your expected tax liability.
Biweekly means every two weeks (26 paychecks per year). Semimonthly means twice a month on specific dates (24 paychecks per year). Biweekly results in slightly smaller but more frequent paychecks.
About the Paycheck Calculator
Your gross salary is rarely your take-home pay. Federal income tax, FICA, state tax, retirement deductions, and health insurance all chip away. This page covers what's taken out of a typical US paycheck and how to optimize the deductions you control.
The Formula
Net pay = Gross − (Federal income tax) − (FICA: 6.2% Social Security + 1.45% Medicare) − (State and local tax) − (Pre-tax benefits like 401(k), HSA, health insurance) − (Post-tax deductions).
Worked Example
$80,000 salary, single, no dependents, in a 5% state tax state. Federal income tax ≈ $10,500. FICA $6,120. State tax $4,000. Subtotal deductions: $20,620. Add $4,800 401(k) (6%) and $2,400 health insurance: total deductions ≈ $27,820. Take-home ≈ $52,180/year, or $4,348/month.
Pre-tax deductions: the most powerful tool you control
401(k), HSA, FSA, and traditional health insurance premiums all come out before federal income tax is calculated. A $1,000/month 401(k) contribution at a 22% federal + 5% state tax bracket saves $270/month in current taxes — meaning the $1,000 contribution only reduces take-home by $730.
Allowances and withholding
Form W-4 controls how much federal tax is withheld. Withholding too much means a large refund (free loan to the government). Withholding too little means owing at tax time. Aim for within $500 of zero — adjust the W-4 'extra withholding' or 'multiple jobs/spouse works' boxes to fine-tune.
Bonuses are not taxed at a higher rate
A common myth. Bonuses are typically withheld at a flat 22% federal rate (vs your marginal rate from W-4), which feels higher in the short term but is reconciled at tax time. The actual tax rate is your normal marginal rate.
Common Mistakes
- Targeting a large tax refund. You gave the government an interest-free loan all year.
- Skipping 401(k) contributions because you 'can't afford it'. The tax savings make the real impact 60-75 cents per dollar contributed.
- Forgetting that state tax varies widely. Texas/Florida: 0%. California top bracket: 13.3%.
Frequently Asked Questions
Why is more taken out of my first paycheck?
Some deductions (insurance, HSA) hit the first paycheck of the month fully. Subsequent paychecks may show less.
How do I lower my paycheck taxes?
Increase 401(k), HSA, FSA contributions. Adjust W-4. Consider itemized deductions if relevant.
