Why PTO builds up gradually, not all at once
Most employers accrue paid time off incrementally throughout the year rather than granting the full annual allotment on day one - this figure is typically what shows up on a pay stub each period.
Worked example
For 120 annual PTO hours accrued across 26 biweekly pay periods:
Accrual Rate = 120 / 26 = 4.615 hours per pay period
Multiplying this per-period rate by the number of pay periods worked so far in the year gives a quick way to check whether your accumulated PTO balance matches what it should be at any given point.
