The Real Cost of Paid Time Off
Why PTO doesn't change salary but raises the true cost of every hour actually worked.
Paid time off does not show up as a separate invoice, which is exactly why it is so easy to overlook — and why so many labor rates are quietly too low. When you give an employee vacation, holidays, and sick days, you pay their wage for hours in which no work is produced. That does not change their annual salary, but it raises the true cost of every hour they actually work. This guide explains the productive-hours concept that fixes the problem.
The Employee Cost Calculator automatically divides by productive hours — here is why that matters.
The core idea: productive hours
A full-time schedule is about 2,080 hours a year (40 hours × 52 weeks). But nobody works all 2,080. Subtract paid time off and you are left with productive hours — the hours you actually get work out of. Your true hourly cost is total annual cost divided by productive hours, not by 2,080.
Types of paid time off to count
- Vacation / PTO: commonly 5–15+ days depending on tenure and policy.
- Federal and company holidays: often around 11 days a year.
- Sick days: frequently 3–7 days, and required by law in many states.
- Other leave: bereavement, jury duty, personal days, and similar.
Added together, 25–30 paid days off a year is typical — that is 200–240 hours, or roughly 10%–12% of the schedule.
Worked example
Take a $25/hour employee whose fully-loaded cost is about $80,000 a year on a 2,080-hour schedule. Suppose they receive 10 vacation days, 11 holidays, and 5 sick days — 26 days, or 208 hours off.
| Basis | Hours | True hourly cost |
|---|---|---|
| Divide by all paid hours (wrong) | 2,080 | ~$38.46 |
| Divide by productive hours (right) | 1,872 | ~$42.74 |
The difference — more than $4 an hour, over 10% — is pure margin you would give away if you priced off the wrong hours.
PTO as an accrued liability
There is a second cost dimension for accounting: unused PTO that carries over is a liability on your books, because in many states you must pay it out when an employee leaves. Generous accrual with low usage can build a real balance-sheet obligation. For day-to-day pricing, though, the productive-hours adjustment is what matters most.
Does more PTO mean you should charge more?
Yes — mathematically. Every extra day off reduces productive hours and nudges your true hourly cost up. That is not a reason to cut PTO (it is a valuable retention tool), but it is a reason to make sure your billable rate reflects the time off you actually grant. Model it explicitly rather than hoping it comes out in the wash.
