Calculating FTE is as simple as dividing resource capacity (in hours) by the working hours in a standard calendar.
The following formula can help:
Here’s a brief example:
Ms. Smith works full-time in her company. So, the standard calendar’s working hours are 40 hours. However, this week, Ms. Smith took one day off. Therefore, she only works for 32 hours. Accordingly, her resource capacity for this week is 0.6 FTE.
Calculation of an annual FTE:
The annual basis for an FTE is 40 hours per week multiplied by 52 weeks, which equals 2080 hours. To calculate the total available FTEs in your company, including both full-time and part-time employees, follow these 4 steps:
Step 1:
First, you need to determine the resource capacity in hours for part-time employees. Let’s assume there are 5 part-time employees working 20 hours per week for a period of 30 weeks. Additionally, 2 part-time employees work 15 hours per week for 35 weeks.
Calculation:
5 × 20 × 30 = 3,000 hours
2 × 15 × 35 = 1,050 hours
So, the total number of hours worked by part-time employees is 4,050 part-time hours when added together.
Step 2:
Now, let’s calculate the number of working hours for full-time employees. Let’s assume there are 8 full-time employees working 40 hours per week for 52 weeks in a year.
Calculation:
8 × 40 × 52 = 16,640 full-time hours
Step 3:
To calculate the total number of working hours, simply add the part-time and full-time hours together.
Calculation:
4,050 part-time hours + 16,640 full-time hours = 20,690 total hours
Step 4:
To calculate the annual FTE of your company, simply apply the formula above. That is: divide the total hours by the annual FTE.
Calculation:
20,690 ÷ 2,080 = 9.95 FTE
So, the company has 9.95 FTE available.
