What does prorated salary mean?

Prorated salary refers to the compensation paid to an employee based on the number of days worked in the given pay period.

Prorated salary may be calculated for the actual number of days worked, plus national holidays and approved leave taken in the period, provided that the employee is entitled to that.

How to calculate prorated salary

Whether you have started a job in the middle of a month or have decided to leave before the end of the month, you may at some point find it necessary to calculate your prorated salary. To do so, we will use the following information:

  • Monthly salary: $1,500;
  • Number of days in the month: 28;
  • Number of days worked in the month: 10; and
  • Number of working days per week: 5.

Now follow these steps:

  1. Find the number of days in the given month: 28.

  2. If you do not work weekends or simply do not work on Sundays, calculate the number of weekend days in that month (that represents the days you do not work). Let's say four Saturdays and four Sundays: 8 days.

  3. Subtract the obtained numbers: 28 - 8 = 20 work days in the month.

  4. Find the number of days you worked in the month: 10.

  5. Find the number of public holidays and the number of approved leave days taken in the period you worked. Let's say there was one holiday and zero approved leave: 1 + 0 = 1.

  6. Add the answers found in the fourth and fifth points: 10 + 1 = 11.

  7. Divide your gross monthly salary by the answer found in the third point: $1,500/20 = $75. This is your daily pay rate.

  8. Multiply the answer found in the previous point by the answer found in the sixth point: $75 × 11 = $825. This is your prorated salary.

If you are entitled to overtime pay and need help calculating this amount, we created the overtime calculator for just that purpose.

How to prorate semi-monthly salary

Follow these steps if you are usually paid semi-monthly and would like to prorate your semi-monthly salary:

  1. Find the number of days worked for the month.
  2. Add this to the number of holidays and approved leave.
  3. Multiply the answer in 2 by the daily pay rate.

Is prorated salary good?

It is good for employers since it makes it possible for them to pay you for the period you actually worked rather than the full pay period.

For employees, it creates a way to ensure they are compensated fairly for their effort when they have not worked the entire pay period.

How do I prorate my monthly salary if I worked 15 days?

Assuming that you had no approved leave and there were no holidays in that month, this is how you calculate your prorated salary:

  1. Get your monthly salary amount.

  2. Find the number of days in the month.

  3. If you do not work weekends, subtract the total number of Saturdays and Sundays to get the total number of workdays.

  4. Divide your monthly payment by the number of work days.

  5. Multiply the answer by the number of days you worked for the month.

  6. You have found your prorated salary.

How much is my prorated salary for 10 days with a $60,000 yearly salary?

Your prorated salary would be $2,500 assuming that you do not work weekends and are calculating for February, which has 20 work days, and you had no approved leave or holidays.

In comparison, your monthly salary would be $5,000.

Is it legal to prorate salary?

It is, undoubtedly, legal to prorate the first and last month's salary.

On the other hand, salaried employees cannot receive prorated salaries for being late. If, however, you are absent for more than one week straight, your employer has the right to refuse to pay you for that week according to US law.

Check the Federal Labor Laws For Salaried Employees for the reference regarding prorating salary if you were absent from work for more than a week at a time.
