What Are PTO Hours?
PTO hours are paid time off measured in hours: time you can take away from work while still being paid, under your employer's policy. Most US employers track PTO in hours rather than days, so a balance of 40 PTO hours is 5 days with an 8-hour workday. You earn PTO hours by accruing them each pay period or hour worked, or by receiving a lump sum at the start of the year.
How you get PTO hours
- Accrual per pay period: a fixed amount is added every paycheck, such as 3.08 hours.
- Accrual per hour worked: you earn a fraction of an hour for each hour you work, such as 0.0385.
- Lump sum (front-loaded): the full year's hours are available on the first day of the year.
- Unlimited PTO: there is no balance to accrue; time off depends on approval. See unlimited vs. accrued PTO.
The PTO accrual rate chart shows what common yearly amounts mean per paycheck.
How PTO hours are used
When you take time off, the hours are subtracted from your balance: a full 8-hour day uses 8 hours, a half day uses 4. If your workday is 10 hours, a full day uses 10. That is why hours are more precise than days for part-time and shift schedules.
Balance, available and pending hours
Your PTO balance is not always what you can request:
- Balance: hours you have earned minus hours already taken.
- Reserved: approved time off that has not happened yet.
- Available: balance minus reserved hours.
- Pending: requests waiting for a decision.
The balance vs. available guide explains each number with an example.
Frequently asked questions
What does PTO hours mean on my pay stub?
It is usually your PTO balance in hours, sometimes with the hours earned and used in that pay period. Check the labels: "accrued", "used" and "balance" are different numbers.
How many days is 40 PTO hours?
5 days with an 8-hour workday, 5.33 days with a 7.5-hour workday, or 4 days with a 10-hour workday. Use the PTO hours to days calculator for your schedule.
Are PTO hours the same as sick leave?
Not always. Some employers combine vacation, personal and sick time into one PTO bank; others keep sick leave separate. Some states and cities have their own paid sick leave rules, so check your employer's policy.
Do PTO hours expire?
That depends on the policy. Some let hours carry over to the next year, some cap the balance, and some require using hours by a deadline. State rules on this differ, so read your policy and your state labor department's guidance.
