## How it works

Annual PTO = accrual rate (hours per period) x periods per year.

## Worked example

Accruing 3.33 hours per biweekly pay period over 26 periods earns about 86.6 hours of PTO per year.

## Assumptions

- Accrual is linear across the year.
- The rate is hours earned per pay period, not per hour worked.

## Common questions

### How do I convert PTO hours to days?

Divide by your daily hours, usually 8: 86.6 hours is about 10.8 days.

### Does accrued PTO expire?

Depends on state law and employer policy; some states ban use-it-or-lose-it policies.
