What is Biweekly Payroll?
Biweekly payroll refers to a payment schedule where employees receive their wages every two weeks. This results in 26 pay periods per year (52 weeks / 2 weeks per period = 26). It's a common payroll frequency in many countries, particularly in the United States, offering a balance between frequent payments for employees and manageable administrative overhead for employers. Understanding how to calculate biweekly payroll is crucial for both accurate compensation and effective financial planning.
Who should use it: Businesses of all sizes that opt for a biweekly pay cycle. Employees working under a biweekly schedule can also use this to estimate their take-home pay. It's particularly useful for understanding the impact of deductions and taxes on each paycheck.
Common misconceptions: A frequent misunderstanding is that biweekly means twice a week; it actually means every two weeks. Another misconception is that it's the same as semi-monthly (which is twice a month, totaling 24 pay periods). The 26 pay periods in a biweekly system mean employees receive two extra paychecks per year compared to semi-monthly schedules, which can impact annual budgeting and tax planning.
Biweekly Payroll Formula and Mathematical Explanation
Calculating biweekly payroll involves several steps to determine the net pay an employee receives after all deductions and taxes. The core idea is to convert annual figures into biweekly amounts and then subtract applicable withholdings.
The primary formula for calculating biweekly payroll net pay is:
Net Biweekly Pay = Gross Biweekly Pay – Total Biweekly Deductions
Let's break down the components:
- Calculate Gross Biweekly Pay: This is the employee's total earnings before any deductions.
Gross Biweekly Pay = Annual Salary / 26 - Calculate Biweekly Pre-Tax Deductions: These are deductions taken out before taxes are calculated.
Biweekly Pre-Tax Deductions = Annual Pre-Tax Deductions / 26 - Calculate Taxable Biweekly Income: This is the amount subject to income taxes.
Taxable Biweekly Income = Gross Biweekly Pay - Biweekly Pre-Tax Deductions - Calculate Estimated Biweekly Taxes: This is based on the taxable income and the employee's tax rate.
Estimated Biweekly Taxes = Taxable Biweekly Income * (Estimated Total Tax Rate / 100) - Calculate Biweekly Other Deductions: These are deductions taken after taxes (or not subject to income tax).
Biweekly Other Deductions = Annual Other Deductions / 26 - Calculate Net Biweekly Pay: The final take-home amount.
Net Biweekly Pay = Gross Biweekly Pay - Biweekly Pre-Tax Deductions - Estimated Biweekly Taxes - Biweekly Other Deductions
Alternatively, using the primary formula:Net Biweekly Pay = Gross Biweekly Pay - (Biweekly Pre-Tax Deductions + Estimated Biweekly Taxes + Biweekly Other Deductions)

Practical Examples (Real-World Use Cases)
Let's illustrate how to calculate biweekly payroll with practical examples:
Example 1: Standard Employee
Sarah earns an annual salary of $70,000. Her annual pre-tax deductions for health insurance and 401k contributions total $4,200. Her estimated combined tax rate is 28%. She has no other annual deductions.
- Annual Salary: $70,000
- Annual Pre-Tax Deductions: $4,200
- Estimated Total Tax Rate: 28%
- Annual Other Deductions: $0
Calculations:
- Gross Biweekly Pay = $70,000 / 26 = $2,692.31
- Biweekly Pre-Tax Deductions = $4,200 / 26 = $161.54
- Taxable Biweekly Income = $2,692.31 – $161.54 = $2,530.77
- Estimated Biweekly Taxes = $2,530.77 * (28 / 100) = $708.62
- Biweekly Other Deductions = $0 / 26 = $0.00
- Net Biweekly Pay = $2,692.31 – $161.54 – $708.62 – $0.00 = $1,822.15
Interpretation: Sarah will receive approximately $1,822.15 every two weeks after all deductions and taxes. This calculation helps her budget effectively for her expenses.
Example 2: Employee with Additional Deductions
John has an annual salary of $90,000. His annual pre-tax deductions (401k, benefits) are $6,000. His estimated tax rate is 32%. Additionally, he has an annual wage garnishment of $1,200.
- Annual Salary: $90,000
- Annual Pre-Tax Deductions: $6,000
- Estimated Total Tax Rate: 32%
- Annual Other Deductions: $1,200
Calculations:
- Gross Biweekly Pay = $90,000 / 26 = $3,461.54
- Biweekly Pre-Tax Deductions = $6,000 / 26 = $230.77
- Taxable Biweekly Income = $3,461.54 – $230.77 = $3,230.77
- Estimated Biweekly Taxes = $3,230.77 * (32 / 100) = $1,033.85
- Biweekly Other Deductions = $1,200 / 26 = $46.15
- Net Biweekly Pay = $3,461.54 – $230.77 – $1,033.85 – $46.15 = $2,150.77
Interpretation: John's take-home pay every two weeks is approximately $2,150.77. The garnishment, being an "other deduction," is subtracted after taxes are calculated, impacting his final net pay.

Key Factors That Affect Biweekly Payroll Results
Several factors significantly influence the final biweekly payroll net pay:
- Annual Salary: The most direct factor. A higher salary generally means higher gross pay, but also potentially higher tax liabilities, depending on the tax bracket.
- Pre-Tax Deductions: Contributions to 401(k)s, HSAs, or health insurance premiums reduce your taxable income, thereby lowering your immediate tax burden. This increases your net pay compared to paying taxes on the full gross amount.
- Tax Rate: This is a critical variable. Fluctuations in federal, state, and local tax laws, as well as changes in an individual's filing status or deductions, can alter the effective tax rate and significantly impact net pay. A higher tax rate means less take-home pay.
- Other Deductions: Post-tax deductions like wage garnishments, court-ordered payments, or certain union dues directly reduce net pay without affecting the tax calculation itself.
- Number of Pay Periods: While fixed at 26 for biweekly, understanding this number is key. It means employees receive two "extra" paychecks annually compared to semi-monthly schedules, which can be beneficial for annual financial goals but requires careful budgeting.
- State and Local Taxes: Beyond federal taxes, varying state and local income tax rates can dramatically alter net pay. Some states have no income tax, while others have progressive rates that increase with income.
- Filing Status and Allowances: While not directly input here, an employee's W-4 form (or equivalent) determines how much tax is withheld. Changes in filing status (single, married) or claiming allowances affect the tax calculation.
- Bonuses and Overtime: This calculator assumes a consistent salary. Bonuses or overtime pay, often taxed at different rates (sometimes higher withholding), would alter the actual net pay for specific periods.
Frequently Asked Questions (FAQ)
A: Biweekly payroll means employees are paid every two weeks, resulting in 26 pay periods per year. Semi-monthly payroll means employees are paid twice per month, resulting in 24 pay periods per year. Biweekly schedules give employees two extra paychecks annually.
A: Typically, an employee is paid for the exact time worked. For salaried employees, this might involve prorating their salary based on the number of working days or hours in the partial pay period. Hourly employees are paid for the hours they have logged.
A: Yes, by submitting a new W-4 form (or state equivalent) to your employer. This allows you to adjust allowances or specify additional withholding amounts to better match your expected tax liability.
A: If tax laws change or your personal financial situation (like income level or deductions) changes, your actual tax liability might differ from the estimate. You should update your W-4 form accordingly to adjust withholding. This calculator uses an estimated rate for planning purposes.
A: This calculator is designed for regular salary payments. Bonuses are often paid separately or included in a specific payroll run and may be subject to different tax withholding rules (often a flat rate or supplemental rate).
A: Pre-tax deductions reduce your taxable income. This means you pay income tax on a smaller amount, resulting in a lower tax bill and a higher net pay compared to if those deductions were made post-tax.
A: The 26 pay periods mean that over a year, employees receive a total amount equivalent to their annual salary spread across 26 payments. This differs from semi-monthly (24 pay periods) and can affect budgeting, especially around the two "extra" paychecks received annually.
A: The estimated tax rate is a simplification. Actual tax liability depends on numerous factors including deductions, credits, filing status, and specific tax laws. This calculator provides a good estimate for planning but is not a substitute for professional tax advice.
