How do I calculate my take-home pay?

Start with gross pay, subtract federal income tax withholding (based on your W-4 and tax brackets), Social Security (6.2%), Medicare (1.45%), state income tax (if applicable), and any pre-tax deductions (401k, health insurance, FSA). The result is your net take-home pay.

Why is my paycheck less than I expected?

Common reasons: your W-4 filing status is set to Single (higher withholding than Married), you have additional withholding requested on your W-4, you're paying pre-tax health insurance premiums, or you recently received a raise into a higher tax bracket. Use our paycheck calculator to reconcile every line item.

How much does a 401k contribution reduce my paycheck?

A 401k contribution reduces your paycheck by less than the contribution amount because it reduces your taxable income. If you're in the 22% bracket, a $500 contribution reduces your federal tax by $110, so your paycheck only decreases by $390, not $500. The $110 goes to your retirement instead of the IRS.

What is FICA tax on my paycheck?

FICA = Social Security (6.2%) + Medicare (1.45%) = 7.65% of gross wages. Social Security only applies up to the annual wage base ($176,100 in 2026). High earners pay an additional 0.9% Medicare surtax on wages above $200,000. Your employer matches your FICA contribution.

Should I claim 0 or 1 on my W-4?

The 2020-and-later W-4 no longer uses exemptions (0/1/2 etc.) — it uses dollar amounts instead. The old "claim 0 for more withholding, claim 1 for less" system is outdated. Fill out the current W-4 based on your actual situation. Married filers and those with children should use the IRS withholding estimator to set the correct allowances.

How do I increase my paycheck without a raise?

Reduce withholding: if you get a large annual refund, update your W-4 to reflect your actual situation (reducing overpayment). Maximize pre-tax deductions: higher 401k contributions reduce taxable income. Move to a no-state-tax state: same salary nets $200–700 more monthly. Choose a high-deductible health plan with an HSA: lower premiums and HSA contributions are pre-tax.

Can I calculate an hourly paycheck with this?

Yes — multiply your hourly rate by hours per period to get gross pay, then this calculator estimates the taxes withheld and your take-home amount. Pair it with the Overtime Calculator if your hours include time and a half.

Tax & Salary

Net paycheck after deductions

Annual Salary

Other Deductions (%)

Your salary is $65,000 — but what actually hits your bank account every two weeks? The gap between gross salary and net pay confuses employees at every income level. Federal income tax withholding, Social Security, Medicare, state taxes, 401k contributions, and health insurance premiums can collectively take 25–40% of your gross pay before you ever see a dollar.

Our free paycheck calculator shows exactly what your paycheck looks like after every deduction. Enter your gross pay, filing status, pay frequency, and optional deductions like 401k and health insurance. The tool applies the correct 2026 federal withholding tables and shows your bi-weekly, semi-monthly, or monthly net pay alongside a breakdown of every line item withheld.

Why Paycheck Calculator Matters

Knowing your actual take-home pay is essential for budgeting. A $65,000 salary in Texas (no state income tax) produces about $4,100/month net — not the $5,417 gross you might naively calculate by dividing $65,000 by 12. In California, the same salary nets about $3,700/month after state tax. This gap of $400–700/month between state tax scenarios can be the difference between affording rent and not.

The paycheck calculator is also essential when evaluating job offers (compare net, not gross), planning retirement contributions (see exactly how much a 401k contribution reduces your net pay), and adjusting W-4 withholding (understanding why your refund was too large or you owed tax in April).

The Paycheck Calculator Formula, Explained

Net Pay = Gross Pay – Federal Tax – State Tax – Social Security – Medicare – Pre-Tax Deductions

Federal income tax is withheld based on your W-4 filing status and the 2026 withholding tables. Social Security: 6.2% of gross pay up to $176,100 annual wage base. Medicare: 1.45% of all gross pay (+ 0.9% Additional Medicare Tax if annual income > $200,000 for single filers). State income tax varies by state (0–13.3%). Pre-tax deductions (401k, HSA, health insurance) reduce the gross subject to income tax but not FICA taxes.

How to Use the Paycheck Calculator: Step by Step

Enter gross pay amount and frequency
Enter your per-paycheck amount or annual salary and select pay frequency: weekly, bi-weekly, semi-monthly, or monthly.
Set filing status and allowances
Match your W-4 elections. Single, Married Filing Jointly, or Head of Household. If you have dependents claimed on your W-4, add those.
Add state
Select your state for state income tax withholding. Select "No State Tax" if you live in FL, TX, WA, NV, WY, AK, SD, TN, or NH.
Enter pre-tax deductions
Add 401k contributions, health/dental/vision premiums, and FSA/HSA contributions. These reduce taxable income.

Paycheck Calculator Examples: Real-World Scenarios

$55,000 Annual Salary — Bi-Weekly Paycheck in Texas

Ashley earns $55,000/year in Texas, files Single, contributes 5% to 401k, pays $200/biweekly for health insurance.

Bi-weekly gross:$2,115.38

401k (5%):$105.77

Health insurance:$200

Taxable gross:$1,809.61

Calculation

Federal tax: ~$156 | SS: $131.15 | Medicare: $30.67 | State: $0 | Total withheld: ~$318. Less deductions: $305.77

Result

Net paycheck: ~$1,491.61 bi-weekly ($38,782/year). Effective take-home: 70.5% of gross. Without the 401k contribution, net would be only $1,455 — the 401k costs $72 net but saves $105 pre-tax.

Comparing Job Offers — $85K in California vs. $80K in Texas

Marcus has offers from San Francisco ($85K) and Austin ($80K). Which nets more?

CA gross monthly:$7,083

CA state tax ~9.3%:$659

TX gross monthly:$6,667

TX state tax:$0

Calculation

CA net: $7,083 – $878 fed – $659 state – $542 FICA = $5,004/month | TX net: $6,667 – $740 fed – $0 state – $510 FICA = $5,417/month

Result

The $80K Texas job actually nets $413/month MORE than the $85K California job — $4,956/year more take-home pay despite the lower gross salary.

Common Mistakes to Avoid

Forgetting that 401k contributions are pre-tax — a $500/month 401k contribution reduces your net pay by only $350–400 (depending on your bracket) because it also reduces your tax withholding.
Confusing filing status on W-4 — claiming Single when married (or vice versa) causes over/underwithholding and tax surprises in April.

Tips & Tricks

Use the IRS Tax Withholding Estimator at IRS.gov annually to check that your withholding matches your expected liability — avoids large refunds (you've given the IRS an interest-free loan) and surprise bills.

Your net paycheck is the real number that drives your financial life. Understanding every line item helps you budget accurately, optimise deductions, and compare job offers on equal footing.
