A paycheck calculator shows your exact take-home pay after all mandatory deductions — federal income tax, Social Security, Medicare, state income tax — plus voluntary pre-tax deductions like 401k and health insurance. Instead of guessing, see precisely how much lands in your bank account each pay period before accepting a job offer or planning your budget.

How to Use This Paycheck Calculator
Understanding your take-home pay is fundamental to personal financial planning, yet most people only discover the actual number when their first paycheck arrives. This paycheck calculator lets you estimate your net pay before accepting a job offer, adjusting your 401k contribution, or changing your withholding elections. It applies 2025 federal tax brackets, FICA taxes, state income tax rates, and pre-tax deductions in the correct order — the same sequence your employer's payroll system uses.
Step 1: Enter Your Annual Gross Salary
Enter your total annual salary before any taxes or deductions are removed. This is the number on your offer letter or current W-2 box 1. If you are an hourly worker, multiply your hourly rate by your hours per week and then by 52 to get your annual figure. For example, $25/hour × 40 hours × 52 weeks = $52,000 per year.
Step 2: Choose Your Pay Frequency
Select how often you receive a paycheck. Weekly gives you 52 paychecks per year with a smaller per-check amount. Bi-weekly (every two weeks) is the most common US pay schedule, producing 26 paychecks — two months per year have three paydays. Semi-monthly (twice per month, typically the 1st and 15th) produces exactly 24 paychecks. Monthly produces 12 larger paychecks. The pay frequency does not change your total annual take-home, only how it is distributed.
Step 3: Select Your Filing Status and State
Your filing status determines which federal tax brackets and standard deduction apply. Single and Married Filing Separately use the same brackets. Married Filing Jointly doubles most bracket thresholds and uses a $30,000 standard deduction — generally the most tax-efficient option for couples. Head of Household applies to unmarried parents supporting a dependent. Your state determines whether state income tax applies and at what rate. Texas, Florida, and Washington have no state income tax; California has the highest rates.
Step 4: Add Pre-Tax Deductions
Pre-tax deductions like traditional 401k contributions and employer-sponsored health insurance premiums are subtracted from your gross pay before federal and state income taxes are calculated. This lowers your taxable income and therefore your tax liability. A $200 bi-weekly 401k contribution in the 22% federal bracket saves you roughly $44 in federal taxes per paycheck. Note that FICA taxes (Social Security and Medicare) are calculated on your full gross pay regardless of pre-tax deductions.
Reading Your Results
The results show a complete per-paycheck breakdown with every deduction itemized, plus an annual summary and effective tax rates. The visual breakdown bar makes it immediately clear what portion of each dollar goes to taxes versus take-home pay. Your effective federal rate is the average rate across all income — typically much lower than your marginal rate (the highest bracket you reach). Use the annual summary to plan savings, set budget limits, and understand your total tax burden for the year.

What taxes does this paycheck calculator include?
This calculator includes 2025 federal income tax using the official IRS progressive tax brackets, Social Security tax (6.2% up to the $176,100 wage base), Medicare tax (1.45%), and simplified flat-rate state income taxes for the top 10 most-populated US states plus a no-state-tax option. Pre-tax deductions like 401k contributions and health insurance premiums are also factored in before calculating taxes.
How does the standard deduction affect my paycheck?
The standard deduction reduces your taxable income before federal income tax is calculated. For 2025, the standard deduction is $15,000 for single filers, $30,000 for married filing jointly, $15,000 for married filing separately, and $22,500 for head of household. This calculator automatically applies the correct standard deduction based on your filing status, then applies the 2025 federal tax brackets to your remaining taxable income.
What is FICA tax and why is it taken out of my paycheck?
FICA stands for the Federal Insurance Contributions Act. It consists of two taxes: Social Security (6.2% of gross wages up to $176,100 in 2025) and Medicare (1.45% with no income cap). These taxes fund Social Security retirement benefits and Medicare health coverage. Unlike income taxes, FICA is calculated on your gross pay before the standard deduction or pre-tax deductions are applied.
How does a 401k contribution reduce my taxes?
A traditional 401k contribution is a pre-tax deduction, meaning it is subtracted from your gross pay before federal and state income taxes are calculated. This reduces your taxable income and therefore your income tax liability. However, 401k contributions are still subject to FICA taxes (Social Security and Medicare). For example, a $200 per-paycheck 401k contribution in the 22% bracket saves you approximately $44 in federal income tax that period.
Why does my actual paycheck differ from this calculator?
This calculator provides estimates based on annualized income and standard deductions. Your actual paycheck may differ for several reasons: your employer may withhold more or less based on your W-4 elections, you may have additional voluntary deductions (dental, vision, FSA, HSA), you may owe additional Medicare tax if you earn over $200,000, or your state may have additional local taxes not covered by this simplified calculator.
Which states are included in this calculator?
This calculator includes the 10 most-populated US states using simplified flat effective rates: California (estimated effective rate), Texas (no state income tax), New York, Florida (no state income tax), Illinois, Pennsylvania, Ohio, Georgia, North Carolina, and Washington (no state income tax). A general 'no state tax' option is also available for states like Nevada, Wyoming, South Dakota, Tennessee, and Alaska.
