PTO accrual is the process of earning paid time off gradually over the course of employment rather than receiving it all at once. Employees accumulate a set number of hours per pay period based on their accrual rate.

How is my PTO accrual rate determined?

Your employer sets the accrual rate, typically based on your annual PTO allotment divided by the number of pay periods in a year. For example, 15 days (120 hours) per year on a biweekly schedule equals 120 ÷ 26 ≈ 4.62 hours per pay period.

What is the difference between hours and days of PTO?

This calculator uses an 8-hour workday as the standard. Divide your PTO hours by 8 to get the equivalent number of full days. You can adjust to a different day length if your standard workday differs.

Can I carry over unused PTO to next year?

This depends on your employer's policy. Some companies allow unlimited rollover, others cap it, and some have a use-it-or-lose-it policy. Check your employee handbook for details.

Does this calculator account for a PTO cap?

Yes — if you enter a maximum accrual cap, the calculator will stop accruing hours once the balance reaches that limit, matching how most capped PTO policies work.

How do I convert my annual PTO days to an accrual rate?

Multiply your annual PTO days by 8 to get total hours, then divide by your number of pay periods per year. Example: 15 days × 8 = 120 hours ÷ 26 biweekly periods = 4.615 hours per period.
