Accrual Per Hour Worked or Per Pay Period
With per-hour accrual, PTO earned is the accrual rate times the hours worked. At 0.05 hours of PTO per hour and 80 hours per biweekly pay period, that is 4 hours of PTO each pay period. With per-pay-period accrual, the same fixed number of hours is credited each pay period. Hourly employees usually accrue per hour worked, which is what a PTO calculator for hourly employees needs to handle.
