Formula
Days Worked:
Days Worked = Total Days - Days Off
Utilization Rate:
Utilization Rate = (Days Worked / Total Days) × 100%
Time Off Percentage:
Time Off % = (Days Off / Total Days) × 100%
Example 1: Annual Time Off
Total Days: 365 (year), Days Off: 20 (vacation + holidays)
Days Worked: 365 - 20 = 345 days
Utilization Rate: (345 / 365) × 100% = 94.5%
Time Off: (20 / 365) × 100% = 5.5%
Example 2: Monthly Time Off
Total Days: 30, Days Off: 2
Days Worked: 30 - 2 = 28 days
Utilization Rate: (28 / 30) × 100% = 93.3%
Time Off: (2 / 30) × 100% = 6.7%

Frequently Asked Questions
What should I include in "days off"?
Include all non-working days: vacation days, sick days, personal days, holidays, weekends (if calculating for working days), and any other time off. For working day calculations, exclude weekends and holidays from total days.
How do I calculate for working days only?
For working days, use 260 days as total (52 weeks × 5 days/week). Then subtract vacation, sick days, and holidays. For example, 260 total days - 15 vacation - 5 sick - 10 holidays = 230 working days.
What's a good utilization rate?
Utilization rate depends on your industry and policies. For employees with standard benefits, 85-95% utilization is typical (accounting for vacation, holidays, sick days). Higher rates may indicate limited time off, while lower rates may indicate excessive absences.
Should I include weekends in total days?
It depends on your purpose. For annual calculations, you can use 365 days (includes weekends) or 260 working days (excludes weekends and holidays). For workforce planning, working days are typically more relevant. Use what makes sense for your analysis.
How do I calculate for multiple employees?
Calculate for each employee separately, or use average days off. For team/department utilization, sum total days and days off across all employees. For example, 10 employees × 260 days = 2,600 total days, 200 days off total = 2,400 days worked.
Can I use this for part-time employees?
Yes! Use the employee's actual working schedule. For example, if a part-time employee works 3 days per week, use 156 total days (52 weeks × 3 days). Then subtract their vacation and sick days from that total.
