Keep reading this article to know what semi-monthly pay means and how to calculate it.

What does semi-monthly pay mean?

Semi-monthly pay is a salary or wage paid twice a month, usually on the 15th and last day but also on the first and 15th day. If one payment date falls on a weekend or holiday, the payment occurs the previous or following business day. Usually, the businesses choose the previous day (Friday or, failing that, Thursday).

As a month contains two of these payments, there are 24 semi-monthly payments per year. Semi-monthly pay usually is confused with biweekly pay, which occurs every two weeks and, therefore, 26 times yearly (you can obtain it with the biweekly pay calculator)

The formula for semi-monthly pay calculation

To better understand what semi-monthly pay means, calculating it is essential. Depending on the available information, there'll be different ways to calculate the semi-monthly pay:

  • Using the monthly wage: As there are two semi-monthly payments during the month, you can obtain their value by dividing the overall monthly salary by 2:

    Semi-monthly wage = (Monthly wage)/2

  • Using yearly wage: There are 24 semi-monthly pay periods during a year. Therefore, we can calculate the semi-monthly pay by dividing the annual salary by 24:

    Semi-monthly wage = (Yearly wage)/24

  • Using weekly wage: As a year has 52 weeks, we can replace the yearly wage with 52 times the weekly pay and calculate the semi-monthly salary as follows:

    Semi-monthly wage = (52 × Weekly wage)/24

  • Using daily wage: Similarly, we can replace the weekly wage with the daily wage times the number of working days per week:

    Semi-monthly wage = (52 × Daily wage × Days per week)/24

  • Using the hourly wage: We can also express the weekly wage as the hours per week times the hourly wage:

    Semi-monthly wage = (52 × Hourly wage × Hours per week)/24

🙋 The calculator assumes five days and 40 hours per week (the most common schedule), but you can change this parameter.
