Short Answer
This paycheck calculator estimates net take-home pay after federal income tax withholding, Social Security (6.2%), and Medicare (1.45%). For a single filer earning $20/hr working 40 hours per week paid biweekly, gross pay is $1,600 per period. Federal withholding is approximately $182. Net take-home is approximately $1,295 before state taxes. For a salaried worker earning $75,000 per year biweekly, gross is $2,884.62 and net is approximately $2,253 for a single filer before state taxes.
Key Takeaways
- Federal income tax is calculated using the IRS Publication 15-T percentage method applied to your annualized gross wages. It is not a flat percentage of each paycheck.
- Social Security is 6.2% of wages up to the 2025 wage base of $176,100. Withholding stops once cumulative wages hit this limit for the calendar year.
- Medicare is 1.45% with no wage base cap. An additional 0.9% surtax applies on wages above $200,000 for single filers and $250,000 for married filing jointly.
- For salaried employees, pay frequency does not change total annual net pay. A $60,000 salary produces the same annual withholding regardless of whether it is paid weekly, biweekly, or monthly.
- Pre-tax deductions (401k, health insurance, FSA) reduce taxable wages and lower actual federal withholding. This calculator does not include them. Actual net pay will be higher if you have pre-tax benefits.

How This Calculator Works
Hourly Mode: Gross Pay Per Period
Gross pay per period equals the hourly rate multiplied by hours worked per week, then scaled to the pay period. For biweekly pay: hourly rate × hours per week × 2. For weekly: hourly rate × hours per week. For semi-monthly and monthly: hourly rate × hours per week × (52 ÷ periods per year).
Salary Mode: Gross Pay Per Period
Gross pay per period equals annual salary divided by the number of pay periods per year. Weekly: ÷ 52. Biweekly: ÷ 26. Semi-monthly: ÷ 24. Monthly: ÷ 12.
Social Security Tax
Social Security is 6.2% of annualized gross wages up to the $176,100 wage base for 2025. The per-period amount is the annualized Social Security tax divided by pay periods. This calculator does not track year-to-date cumulative wages. For workers approaching the wage base, actual withholding will stop mid-year once the limit is reached.
Medicare Tax
Standard Medicare is 1.45% on all gross wages. The Additional Medicare Tax of 0.9% applies to annualized wages exceeding $200,000 for single filers and head of household, or $250,000 for married filing jointly. This calculator estimates based on annualized wages relative to these thresholds.
Federal Income Tax Withholding
The calculator uses the IRS Publication 15-T percentage method (annualized approach) for 2025:
- Annualize the per-period gross pay (multiply by pay periods per year).
- Add Step 4a other income; subtract Step 4b additional deductions.
- Apply the percentage method tax tables for the W-4 filing status to the adjusted annual amount.
- Subtract Step 3 dependent credits from the tentative annual withholding.
- Divide by pay periods to get per-period federal withholding.
- Add Step 4c extra withholding per period.
State Income Tax (Optional)
The calculator applies a flat state rate to gross pay per period when entered. States with graduated brackets (California, New York, Illinois) require a state-specific calculation. Nine states have no state income tax: Texas, Florida, Nevada, Washington, Wyoming, South Dakota, Alaska, Tennessee, and New Hampshire. For these states, leave the state rate field blank.
Real-World Paycheck Scenarios
Scenario 1: Hourly Worker, Single Filer, Texas (No State Tax)
Maria earns $22 per hour working 40 hours per week at a warehouse in Dallas, Texas. She is paid biweekly and files as single with a standard W-4. Her biweekly gross is $22 × 40 × 2 = $1,760.
Annualized gross is $45,760. Federal withholding detail: $1,192.50 (10% on $11,925) plus $4,053.60 (12% on $33,780 from $11,925 to $45,705) = $5,246.10 annual, divided by 26 periods = $201.77. Adjusted for annualized wages of $45,760, approximate per-period withholding is $181.42. Effective federal rate on gross: approximately 11.5%.
Scenario 2: Salaried Worker, Married Filing Jointly, California
David earns $90,000 per year as a software engineer in San Francisco. He is paid biweekly and files as married filing jointly. California has a state income tax. This example uses an approximate 6% flat rate for illustration; actual California withholding uses graduated brackets through the SDI program and DE 4 form. Biweekly gross: $90,000 ÷ 26 = $3,461.54.
Federal withholding detail (MFJ): Annualized gross $90,000. Applied to MFJ table: $2,385.00 (10% on $23,850) plus $7,938.00 (12% on $66,100) = $8,623 annual withholding ÷ 26 = $331.65. The California estimate uses a flat 6% for illustration only. Actual state withholding will differ. Use the California SDI and income tax withholding tables at ftb.ca.gov for the precise amount.
Practitioner Insight
The most common paycheck withholding mistake we see involves dual-income households. Each spouse earns a salary, each W-4 is filed independently, and neither employer knows about the other income. The result: each employer withholds at the married rate assuming that salary is the only income, and the combined household ends up in a higher bracket than either employer anticipated. The solution is to complete the Multiple Jobs Worksheet on Form W-4 and resubmit. It takes 15 minutes and prevents a February tax bill.
We also see hourly workers surprised by the drop in take-home pay when they move from part-time to full-time. More hours per week means more annualized wages, which pushes the annualized income into a higher bracket. The federal withholding per hour increases as total annual wages rise. A worker going from 20 to 40 hours per week does not simply double their net pay because the bracket effect increases per-hour withholding on the additional earnings.
A third situation worth flagging: employees who claim exempt on their W-4 because they owed no tax last year. If income increases mid-year through a promotion or a second job, the exempt election stops all federal withholding. They can owe a substantial amount at filing and may face the underpayment penalty. Claiming exempt requires meeting both the prior-year no-tax-owed and current-year same-expectation tests. We flag this during any W-4 review with a new client.
When This Calculator Gives a Less Accurate Estimate
- Pre-tax deductions not entered: A 401(k) contribution of $300 per biweekly period reduces taxable wages by $300. Federal withholding is calculated on the lower amount. This calculator does not include pre-tax deductions; actual net pay is typically higher than the estimate.
- Dual-income households: Each employer withholds independently based only on wages it pays. If both spouses earn income and each W-4 uses independent single-job elections, combined withholding is often insufficient. Complete the Multiple Jobs Worksheet on Form W-4 or use the IRS withholding estimator at irs.gov.
- Hourly workers with variable hours: This calculator uses consistent weekly hours across all periods. Workers with overtime, irregular hours, or seasonal variation will see different actual paychecks. Overtime premium pay may also be treated as supplemental wages by some payroll systems.
- States with graduated brackets: The optional state field uses a flat percentage. California, New York, New Jersey, and most states use graduated structures. The flat-rate estimate may differ from actual state withholding at higher income levels.
- Bonuses and supplemental wages: Bonuses are typically withheld at the 22% supplemental rate (below $1 million) or at the aggregate method rate. This calculator covers regular wages only.
Frequently Asked Questions
How is take-home pay calculated from a paycheck?
Take-home pay equals gross pay minus federal income tax withholding, Social Security tax (6.2%), Medicare tax (1.45%), and any state income tax. Federal withholding is calculated using IRS Publication 15-T based on your W-4 filing status and annualized wages. Social Security stops once cumulative wages reach $176,100 for 2025. An additional 0.9% Medicare surtax applies to wages above $200,000 for single filers. Pre-tax benefit deductions such as 401(k) contributions and health insurance reduce taxable gross wages and are not included in this calculator.
What is the difference between hourly and salary paycheck calculations?
For hourly employees, gross pay per period equals the hourly rate multiplied by hours worked in that period. For salaried employees, gross pay per period equals annual salary divided by pay periods per year. The federal withholding method is the same for both: IRS Publication 15-T annualizes the per-period gross, applies the graduated tables for the W-4 filing status, then divides back by pay periods. FICA taxes apply at the same rates regardless of whether the worker is hourly or salaried.
Does pay frequency affect my annual take-home pay?
For a fixed annual salary, pay frequency does not change total annual net pay. A $60,000 salary paid biweekly produces the same annual withholding as the same salary paid semi-monthly or monthly. Individual paychecks are smaller or larger based on frequency, but annual totals are consistent. For hourly workers, total annual pay depends on actual hours worked each period, not just the frequency.
What is the Social Security wage base for 2025?
The Social Security wage base for 2025 is $176,100. Social Security tax at 6.2% applies to wages up to this amount. Withholding stops once cumulative wages for the year exceed $176,100. Medicare has no wage base limit. An additional 0.9% Medicare surtax applies to wages above $200,000 for single filers and $250,000 for married filing jointly.
How does my W-4 affect my paycheck withholding?
Your W-4 filing status determines which Publication 15-T withholding table applies. Step 3 dependent credits reduce annual tentative withholding before it is divided by pay periods. Step 4a additional income increases the annualized base. Step 4b deductions reduce it. Step 4c requests extra withholding per period. FICA taxes are not affected by W-4 elections. A new W-4 takes effect on the first payroll period processed after you submit it to your employer.
Why does my actual paycheck differ from this estimate?
This calculator estimates standard federal withholding and optional flat-rate state withholding. Actual paychecks also reflect pre-tax deductions (health insurance, 401k, FSA), post-tax deductions (Roth 401k, garnishments), year-to-date cumulative Social Security tracking, and employer-specific payroll adjustments. The calculator assumes consistent pay each period. Results will differ if your employer uses the aggregate method for supplemental wages or if W-4 changes were applied mid-year.
Do overtime wages affect my tax rate?
Overtime wages increase your annualized gross, which may push a portion of income into a higher federal bracket. Per-period federal withholding is recalculated using the higher annualized wages when overtime is paid. Social Security and Medicare apply at flat rates on all wages. Under the One Big Beautiful Bill Act, qualifying overtime premium pay may be deductible for federal income tax purposes for TY 2025 through TY 2028. This deduction is claimed on your federal return, not reflected in paycheck withholding.
What pre-tax deductions reduce paycheck withholding?
Traditional 401(k) and 403(b) contributions, employer-sponsored health insurance premiums under a Section 125 plan, FSA contributions, and HSA payroll deductions reduce gross wages subject to federal income tax withholding. They do not generally reduce Social Security or Medicare taxes. A worker contributing $500 per biweekly period to a 401(k) reduces per-period taxable wages by $500, lowering federal withholding on that amount. This calculator does not include pre-tax deductions; actual net pay will be higher if they apply.
What To Do Next
Decision Step
If your paycheck estimate looks lower than expected, check whether pre-tax benefit deductions (401k, health insurance) are reducing your taxable wages. Actual net pay including pre-tax deductions will be higher than this estimate. To understand how your federal withholding connects to year-end tax liability, see our How Payroll Taxes Work guide.
