Paycheck Calculator - Take Home Pay Estimator
Calculate your take-home pay after federal tax, state tax, FICA, 401k contributions, and health insurance deductions. Estimate your net pay per paycheck.
How to Use This Paycheck
Follow these steps to estimate your take-home pay:
- Enter your gross pay per period. This is the total amount you earn for a single pay period before any deductions. You can find this at the top of your pay stub, often labeled "Gross Pay" or "Total Earnings." If you only know your annual salary, divide it by the number of pay periods per year (e.g., divide by 26 for biweekly).
- Select your pay frequency. Choose weekly (52 paychecks/year), biweekly (26), semi-monthly (24), or monthly (12). This determines how the calculator annualizes your figures.
- Adjust the federal tax rate. Use the slider to set your estimated marginal federal tax bracket. Most middle-income earners fall in the 22% or 24% bracket. Check your most recent tax return or pay stub for guidance.
- Adjust the state tax rate. Set this based on your state of residence. If you live in a state with no income tax (Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington, or Wyoming), set this to 0%.
- Set your 401(k) contribution percentage. Enter the percentage of gross pay you contribute to a traditional 401(k). This amount is deducted pre-tax, lowering your taxable income.
- Expand advanced settings to fine-tune Social Security rate, Medicare rate, and health insurance premium per paycheck if needed.
To read your pay stub and verify the results, look for the "Deductions" or "Withholdings" section. Compare the federal tax, state tax, Social Security, Medicare, retirement, and insurance lines to the calculator output. Small differences are normal because employers use IRS withholding tables and your specific W-4 elections rather than a flat rate.
What Is Paycheck?
A paycheck calculator estimates the amount of money you actually take home after every deduction is subtracted from your gross pay. The gap between what you earn and what lands in your bank account can be surprisingly large, and understanding each line item on your pay stub is essential for accurate budgeting and financial planning.
Your gross pay is the total amount your employer pays you for a pay period before anything is taken out. Your net pay (also called take-home pay) is what remains after all mandatory and voluntary deductions. The most common deductions include federal income tax, which is withheld based on your W-4 elections and IRS tax brackets; state income tax, which varies by state and ranges from 0% in states like Texas, Florida, and Nevada up to over 13% in California; Social Security tax at 6.2% of wages up to the annual wage base limit; Medicare tax at 1.45% of all wages with an additional 0.9% surtax on high earners; health insurance premiums for medical, dental, and vision coverage; and 401(k) or other retirement contributions that reduce your taxable income while building long-term wealth.
Employees in the United States are typically paid on one of four schedules. Weekly pay results in 52 paychecks per year, biweekly pay produces 26 paychecks, semi-monthly pay yields 24 paychecks (typically on the 1st and 15th of each month), and monthly pay delivers 12 paychecks. Your pay frequency affects the size of each individual paycheck but not your annual totals. This calculator supports all four frequencies so you can see exactly what to expect on payday regardless of your schedule.
Formula & Methodology
Paycheck withholding starts with your gross pay and applies deductions in a specific order. Pre-tax deductions like traditional 401(k) contributions are subtracted first, which reduces the income subject to federal and state income tax. However, FICA taxes (Social Security and Medicare) are calculated on the full gross pay before any retirement deductions.
Your W-4 form plays a major role in how much federal tax is withheld. The W-4 tells your employer your filing status (single, married filing jointly, head of household), whether you have multiple jobs, and any additional withholding or credits you claim. Employers use IRS Publication 15-T withholding tables to translate your W-4 into a per-paycheck federal tax amount. This calculator simplifies that process by applying a flat estimated rate.
The federal tax system uses progressive brackets, meaning different portions of your income are taxed at different rates. To estimate the per-paycheck impact, your employer annualizes your paycheck, applies the tax brackets to the annual figure, and then divides the result back down to a single pay period. The formulas used in this calculator are:
- 401(k) Deduction = Gross Pay × (401k Rate / 100)
- Taxable Income = Gross Pay − 401(k) Deduction
- Federal Tax = Taxable Income × (Federal Rate / 100)
- State Tax = Taxable Income × (State Rate / 100)
- Social Security = Gross Pay × 6.2%
- Medicare = Gross Pay × 1.45%
- FICA = Social Security + Medicare
- Total Deductions = Federal Tax + State Tax + FICA + 401(k) + Health Insurance
- Net Pay = Gross Pay − Total Deductions

Practical Examples
Example 1 — Biweekly, Middle Income: A worker earns $3,000 gross pay biweekly (about $78,000 per year). They are in the 22% federal bracket, pay 5% state tax, contribute 6% to a 401(k), and have no health insurance deduction through work. The 401(k) deduction is $180, reducing taxable income to $2,820. Federal tax is $620.40, state tax is $141.00, Social Security is $186.00, and Medicare is $43.50 for a combined FICA of $229.50. Total deductions come to $1,170.90, leaving a net pay of $1,829.10 per paycheck. Annualized, that is $78,000 gross and $47,556.60 net.
Example 2 — Monthly, Higher Income in a No-Tax State: A professional in Texas earns $8,000 gross monthly ($96,000 per year) with 0% state tax, a 24% federal rate, 10% 401(k) contribution, and $200 per month in health insurance premiums. The 401(k) deduction is $800, bringing taxable income to $7,200. Federal tax is $1,728, state tax is $0, Social Security is $496.00, and Medicare is $116.00 for a FICA total of $612.00. Total deductions are $3,340.00, yielding a net pay of $4,660.00 per month or $55,920 annually. Living in a no-tax state saves this worker roughly $360 per month compared to a state with a 5% rate.
Example 3 — Weekly, Entry-Level Income: An hourly employee earns $750 gross per weekly paycheck ($39,000 per year). They fall in the 12% federal bracket, pay 4% state tax, contribute 3% to a 401(k), and have $50 per paycheck deducted for health insurance. The 401(k) deduction is $22.50, so taxable income is $727.50. Federal tax is $87.30, state tax is $29.10, Social Security is $46.50, and Medicare is $10.88 for FICA of $57.38. Total deductions are $246.28, and net pay is $503.72 per week. That works out to an annual take-home of approximately $26,193. Even a modest 3% 401(k) contribution builds retirement savings of $1,170 per year while only reducing each weekly paycheck by $22.50.
