How much of the time off you grant is actually taken, and what the unused balance is worth on your balance sheet. Low utilization is one of the few workforce signals worth flagging, and almost nobody measures it. Every number on this page is calculated in your browser and never leaves your device.
Utilization only means something as a trend, and Q4 is where the story usually shows up. The HRAnalyst™ Workbook is a printable tracker for every calculator on this site, with the formula, the recommended cadence and space for four quarters. Join the list and we will send it, along with new calculators and workforce analytics as they publish.
Formula used
Utilization Percent = (Days Taken ÷ Days Accrued) × 100
Days Taken per Employee = Days Taken ÷ Employees
Unused Days = Days Accrued - Days Taken - Days Forfeited
Daily Rate = Average Annual Salary ÷ Working Days per Year
PTO Liability = Unused Days × Daily Rate
Liability per Employee = PTO Liability ÷ Employees
Days forfeited is optional and is treated as zero when it is left blank. Utilization above 100 percent is possible and correct when time was taken in advance of accrual. When days taken and days forfeited together exceed days accrued, the unused balance is held at zero for the liability rather than carried as a negative figure, so the dollar result is never negative.
Utilization below roughly half of what is granted is worth investigating, and the cause is rarely obvious. It can reflect workload, understaffing, a culture where taking time is discouraged, or a policy that grants more than anyone realistically uses. The number tells you to look. It does not tell you what you will find.
Forfeiture rules vary by state and some states prohibit use it or lose it entirely. Confirm your obligations before relying on a forfeiture assumption.
Where nothing accrues there is no denominator, so utilization is not measurable for that group. Run this on the accruing population only and report the unlimited group on its own terms, usually as days taken per employee.
A tenured group that is granted more days looks worse for taking exactly the same amount of time as a newer group. Segment by accrual tier before you compare, or you will read a policy difference as a behavior difference.
The liability distorts in whichever direction your senior population sits, because those employees usually hold both the higher daily rate and the larger unused balance. If pay is widely spread, run the calculation band by band and add the results rather than valuing everyone at one daily rate.
