Salary Paycheck Calculator
Calculate your net paycheck for a given annual salary, specifying your pay frequency and filing status. This calculator uses the same IRS percentage-method tables as a payroll department: it annualizes your gross pay per period, applies the progressive federal income tax brackets for your filing status, and subtracts Social Security (6.2% up to the $176,100 wage base for 2025) and Medicare (1.45% with no cap). The result is your take-home pay per paycheck in dollars and cents. Enter your annual salary, choose weekly, biweekly, semimonthly, or monthly pay, select your W-4 filing status, and request any additional federal withholding per period if you wish. The calculator instantly shows gross pay per period, federal income tax deducted, FICA taxes, total deductions, and your net (take-home) pay. This is most useful for salaried employees who want to know their exact paycheck amount without the complexity of hourly schedules or multiple earning periods. The tool does not include state income tax, pre-tax benefits, or post-tax deductions. Two FAQs address common questions: what the Social Security wage base means, and how the annualized withholding method works.
On a $65,000 annual salary paid biweekly, a single filer takes home roughly $1,913 per paycheck after federal income tax, Social Security (6.2%) and Medicare (1.45%). Enter your own figures below for an exact result.
How federal paycheck withholding works
Your employer calculates federal income tax withheld each pay period using the IRS percentage method (IRS Publication 15-T, Worksheet 1). The steps are:
- Calculate gross pay for the period (annual salary divided by pay periods).
- Multiply gross pay by the number of pay periods to annualize it, then subtract the applicable withholding allowance for your filing status ($10,000 for single/HOH, $20,000 for MFJ in 2025).
- Apply the 2025 progressive tax brackets to the annualized, adjusted wage.
- De-annualize the result (divide by pay periods) to get the per-period withholding amount.
- Add any additional withholding you requested on Form W-4.
Social Security is 6.2% of gross pay until your cumulative wages reach $176,100 for the year. Medicare is 1.45% of all wages with no ceiling. These are FICA taxes, not income tax.
gross pay = annual salary / pay periods per year
annualized wages = gross pay x pay periods - filing-status allowance
FIT (annualized) = bracket calculation on annualized wages
FIT per period = FIT (annualized) / pay periods
SS tax = min(gross pay, remaining SS wage base) x 0.062
Medicare tax = gross pay x 0.0145
net pay = gross pay - FIT per period - SS tax - Medicare tax - additional withholding
2025 federal income tax withholding brackets
These are the IRS Pub 15-T percentage-method tables for 2025, applied to annualized wages after subtracting the withholding allowance. The brackets are marginal: only the income within each band is taxed at that rate.
| Rate | Single / HOH annualized wages over | Married filing jointly annualized wages over |
|---|---|---|
| 10% | $0 | $0 |
| 12% | $11,925 | $23,850 |
| 22% | $48,475 | $96,950 |
| 24% | $103,350 | $206,700 |
| 32% | $197,300 | $394,600 |
| 35% | $250,525 | $501,050 |
| 37% | $626,350 | $1,252,700 |

Worked example: $65,000 salary, biweekly, single
- Gross pay per period = $65,000 / 26 = $2,500.00.
- Annualized wages = $2,500 x 26 = $65,000. Subtract single allowance ($10,000) = $55,000.
- FIT on $55,000 (single brackets): 10% on first $11,925 = $1,192.50; 12% on $11,925 to $48,475 = $4,386.00; 22% on $48,475 to $55,000 = $1,435.50. Total = $7,014.00 annualized.
- FIT per period = $7,014.00 / 26 = $269.77.
- Social Security = $2,500 x 0.062 = $155.00.
- Medicare = $2,500 x 0.0145 = $36.25.
- Net pay = $2,500.00 - $269.77 - $155.00 - $36.25 = $2,038.98.

Frequently asked questions
How is federal income tax withheld from my paycheck?
Your employer uses the IRS percentage method from IRS Publication 15-T. Your gross pay for the period is annualized, a flat amount is subtracted based on filing status and pay periods, then the result is run through the progressive tax brackets. The tax is then de-annualized back to a per-period amount.
What is the Social Security wage base for 2025?
The Social Security taxable wage base for 2025 is $176,100, as published by the Social Security Administration. The employee rate is 6.2%, so the maximum Social Security tax an employee pays in 2025 is $10,918.20. Once your cumulative wages for the year exceed $176,100, no further Social Security tax is withheld.
Does Medicare tax have a wage cap?
No. The standard Medicare (Hospital Insurance) rate is 1.45% on all wages with no ceiling. Higher earners pay an additional 0.9% Additional Medicare Tax on wages above $200,000 (single) or $250,000 (married filing jointly), but this calculator applies the base 1.45% rate only, which matches what employers withhold from each paycheck.
What does 'additional withholding' mean?
IRS Form W-4 allows you to request extra dollars withheld from each paycheck, on top of the standard calculated amount. This is useful if you have other income not subject to withholding (freelance work, investments) and want to avoid an underpayment penalty at tax time.
