How this calculator works
- Your pay becomes a yearly amount. Hourly pay counts your hours a week for 52 weeks, so paid holidays and vacation count as worked weeks.
- Federal income tax uses the 2026 IRS brackets and standard deduction for your filing status: $16,100 single, $32,200 married filing jointly and $24,150 head of household. With a 2026 Form W-4 and nothing else filled in, this is what IRS Publication 15-T has your employer withhold over the year.
- Social Security is 6.2% of pay up to $184,500. Medicare is 1.45% of all pay, plus 0.9% on pay over $200,000.
- State income tax uses each state's 2026 brackets, standard deduction and personal exemptions for a full-year resident with no dependents. Required state payroll deductions, like paid family leave or disability insurance, are included.
- It assumes one job all year and no other income, credits or itemized deductions. Dependents and the Child Tax Credit are not included, so if you file as head of household or claim children on your Form W-4, your federal tax will usually be lower than shown. Your real paycheck can differ by a few dollars, because payroll rounds each paycheck and some states use their own withholding tables.
- Hours over 40 a week count at your regular rate. For time and a half, use the overtime calculator. A 401(k) is held to the 2026 IRS limit of $24,500; catch-up contributions at 50 and older are not included.
