What the Net Paycheck by State Calculator does
This calculator estimates your take-home pay — the money that actually lands in your bank account each payday — based on the U.S. state you work in. Starting from your annual gross salary, it subtracts the three withholdings that shrink almost every American paycheck: federal income tax, FICA (Social Security and Medicare), and state income tax. Because state income tax is the piece that changes the most from place to place, choosing your state is what makes the net figure specific to you.
It covers all 50 states plus the District of Columbia. Nine states levy no tax on wage income, some use a single flat rate, and the rest use progressive brackets — the tool applies the correct treatment for whichever state you pick. Results are estimates: they use current federal tax-year rates and each state's most recent published rate schedule, and they do not model pre-tax deductions (such as 401(k) or health premiums), tax credits, local city or county taxes, or state-specific deductions and exemptions.
How to use it
Enter your annual gross salary (your pay before any taxes or deductions). Pick your filing status — Single or Married Filing Jointly — which sets your federal brackets and standard deduction. Choose how often you are paid (weekly, bi-weekly, semi-monthly, monthly, or annual) so the tool can divide your yearly take-home into a per-paycheck amount. Finally, select your state. The result shows your take-home pay per paycheck at the top, followed by a breakdown of gross pay, federal tax, FICA, state tax, total withholding, and your effective tax rate.
The formula explained
Your net pay is simply gross pay minus every tax withheld:
$$ \text{Take-Home Pay} = \text{Gross Pay} - \text{Federal Tax} - \text{FICA} - \text{State Tax} $$
Federal and state income taxes apply to your taxable income, not your full salary. This tool uses the federal standard deduction as the baseline:
$$ \text{Taxable Income} = \text{Gross Salary} - \text{Standard Deduction} $$
Income tax is then charged progressively — each slice of income is taxed at its own bracket rate, and the pieces are added together:
$$ \text{Income Tax} = \sum_i \text{rate}_i \times (\text{income taxed in bracket } i) $$
FICA is a flat payroll tax: 6.2% for Social Security up to an annual wage base, plus 1.45% for Medicare on all wages (high earners pay an extra 0.9% Medicare surtax above a threshold):
$$ \text{FICA} = 6.2\% \times \min(\text{Gross},\ \$184{,}500) + 1.45\% \times \text{Gross} $$
Finally, the annual take-home is divided by the number of pay periods in a year to give the amount on each paycheck:
$$ \text{Per-Paycheck Pay} = \frac{ \text{Net Annual Take-Home} }{ \text{Number of Pay Periods} } $$
Worked example
Consider a single filer earning $60,000 a year in Colorado, paid monthly. Subtracting the standard deduction gives taxable income of $60,000 − $16,100 = $43,900. Federal tax on that (10% on the first $12,400 plus 12% on the remaining $31,500) is $1,240 + $3,780 = $5,020. FICA is 6.2% + 1.45% of the full $60,000 = $3,720 + $870 = $4,590. Colorado's flat 4.4% rate on the $43,900 taxable income is $1,931.60. Total tax is $5,020 + $4,590 + $1,931.60 = $11,541.60, leaving a net annual take-home of $48,458.40. Divided across 12 monthly paychecks, that is $4,038.20 per paycheck, an effective tax rate of about 19.24%.
Frequently asked questions
Is this my exact take-home pay? No — treat it as a close estimate. It excludes pre-tax deductions like 401(k) contributions and health insurance premiums, tax credits, local city or county income taxes, and state-specific deductions or exemptions, all of which shift your real number. It also applies each state's single-filer schedule to income after the federal standard deduction.
Which taxes are included? Three: federal income tax (using current-year brackets and the standard deduction for your filing status), FICA (Social Security at 6.2% up to the annual wage base and Medicare at 1.45% on all wages, plus the 0.9% additional Medicare tax for very high earners), and state income tax for the state you select.
Why do some states show no state tax? Nine states — Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, and Wyoming — do not tax wage income, so their state tax is $0. Flat-tax states apply one rate to all taxable income, while the remaining states use progressive brackets that rise with income.
