What is Bi-Weekly Pay?
Bi-weekly pay is a payroll schedule where employees are paid every two weeks, typically on a specific day of the week (like Friday). This results in 26 pay periods per year . For many employees, this is a preferred schedule as it provides a consistent cash flow every 14 days.
How to Calculate Bi-Weekly Pay
Calculating your gross bi-weekly pay depends on whether you are salaried or hourly:
For Salaried Employees: Divide your gross annual salary by 26. (Example: $52,000 / 26 = $2,000 gross per pay period).For Hourly Employees: Multiply your hourly rate by the number of hours worked in two weeks. (Example: $20/hr x 40 hours x 2 weeks = $1,600 gross per pay period).
Understanding Net Pay (Take-Home)
Your net pay is what remains after mandatory and voluntary deductions. These typically include:
Deduction Type
Description
Federal Income Tax
Based on your tax bracket and filing status.
FICA Taxes
Social Security (6.2%) and Medicare (1.45%).
Health Insurance
Your portion of medical, dental, or vision premiums.
401(k) / Retirement
Pre-tax contributions toward your future savings.
The "Magic" 3-Paycheck Months
Because there are 52 weeks in a year, a bi-weekly schedule results in 26 checks. Most months contain two paychecks, but twice a year, you will receive three paychecks in a single month. Financial experts often suggest treating these "extra" checks as bonus money for savings or debt repayment, as most monthly budgets are built around two checks.
