Formula and Logic
This calculator uses standard biweekly pay calculations used by most U.S. employers:
- Salaried: Annual gross salary ÷ 26 (biweekly pay periods per year) = Gross biweekly pay
- Hourly: (Hourly wage × Hours per week) × 52 ÷ 26 = Gross biweekly pay
- Taxes: Gross biweekly pay × Federal/state tax rate = Tax withheld per pay period
- 401(k): Gross biweekly pay × Contribution percentage = 401(k) deduction per pay period
- Net pay: Gross biweekly pay - (Total taxes + 401(k) + Health insurance + Other deductions)
Annual net pay is calculated as Net biweekly pay × 26, and monthly net pay is Annual net pay ÷ 12.
Practical Notes
Keep these finance-specific tips in mind when using this calculator:
- Tax rates vary by income bracket, filing status, and location: Use the percentages listed on your most recent pay stub for accuracy.
- 401(k) contributions reduce taxable income: Pre-tax contributions lower your federal and state tax withholdings, which this calculator accounts for.
- Biweekly pay cycles result in 26 pay periods per year: This is 2 extra pay periods compared to monthly pay, which can boost annual income.
- Deductions may be pre-tax or post-tax: Health insurance and 401(k) are typically pre-tax, while wage garnishments or Roth 401(k) contributions are post-tax. Adjust your entries accordingly.
- Net pay may differ from take-home pay: Some employers deduct post-tax benefits like life insurance or commuter benefits, which you can include in "Other Deductions".

Frequently Asked Questions
Is biweekly pay the same as semi-monthly pay?
No. Biweekly pay occurs every 2 weeks (26 pay periods per year), while semi-monthly pay occurs twice per month (24 pay periods per year). This calculator is for biweekly pay cycles only.
Why is my calculated net pay different from my actual pay stub?
Differences may come from incorrect tax rates, unaccounted deductions (like FSA contributions or wage garnishments), or pre-tax vs post-tax deduction mix-ups. Use your most recent pay stub details for the closest match.
Can I use this calculator for freelance or gig work?
Yes. If you freelance, enter your average weekly hours and hourly rate, then add self-employment tax (15.3%) to the federal tax rate field to estimate total tax withholdings.
