Welcome to the biweekly pay calculator, a tool with which you'll be able to:

  • Calculate your biweekly income based on your hourly, annual, or any other rate;
  • Use the bi-weekly salary to calculate the annual salary; and
  • Much more.

To calculate the biweekly salary, simply input the annual, hourly, o any other wage you know. You can use the calculator in various ways: for example, you can calculate the yearly salary by inputting the biweekly pay.

🙋 Don't confuse this tool with our semi-monthly pay calculator. While semi-monthly pay occurs twice a month, biweekly payment occurs every two weeks (usually on Fridays). Some months can have three Fridays on which you can receive pay.

What is a biweekly pay period, and how many of them a year has?

Biweekly pay is a salary or wage paid every two weeks, usually on Fridays. If one payment date falls on a holiday, the standard practice is making the payment on the previous day (i.e., Thursday).

As a year contains 52 weeks, there are 26 biweekly payments annually (52/2 = 26). Biweekly pay usually is confused with semi-monthly pay, which occurs twice a month and, therefore, 24 times annually.

To better understand biweekly pay, calculating it is essential. In the next section, we show how to do it.

Formulas to calculate biweekly income

Depending on the available information, there'll be different ways to calculate the biweekly pay:

  • We know biweekly pay occurs every two weeks. Therefore, we can calculate the biweekly income as twice the weekly wage:

    Biweekly wage = 2 × Weekly wage

  • For a wage earner who gets paid hourly, we can calculate the biweekly salary from the formula above. Remembering that the weekly wage is the hourly wage times the hours worked per week:

    Biweekly wage = 2 × Hourly wage × Hours per week

  • We can also express the first formula in terms of the daily wage. Considering that Weekly wage = Daily wage × Days per week:

    Biweekly wage = 2 × Daily wage × Days per week

  • If you only know the overall annual salary and want to know how much it will be biweekly, divide the salary by 26 (as there are 26 biweekly pays annually):

    Biweekly wage = (Annual wage)/26

  • If you know the monthly wage, you can use the previous formula and replace the annual wage with twelve times the monthly wage:

    Biweekly wage = (12 × Monthly wage)/26

How do I use the bi-weekly salary to calculate the annual salary?

To calculate the annual from the bi-weekly salary, multiply the biweekly salary by 26. In other words, the annual equals 26 times the biweekly salary:
