PTO Accrual for New Hires and Partial Pay Periods
Your first and last pay periods at a job are rarely complete, and a calendar-year allowance doesn’t start fresh on your hire date. This guide shows how PTO accrues when you start or leave partway through a period or a year, using a 120-hour allowance and biweekly periods that end on Fridays.

Starting partway through a pay period
Suppose the pay period runs Saturday, July 4 to Friday, July 17, 2026, and you start on Monday, July 6 — 12 of its 14 days. Some employers credit nothing for that period because it wasn’t complete. Others prorate: 120 ÷ 26 × 12 ÷ 14 ≈ 3.96 hours. A few prorate by hours worked instead of calendar days.
Your first year on a calendar-year allowance
On a calendar-year policy the year doesn’t restart when you’re hired; you earn only for the full periods left in it. Counting only complete periods that end by December 31, 2026:
| Start date | Full periods left in 2026 | PTO earned in 2026 |
|---|---|---|
| Monday, January 5 | 24 | 110.77 hours |
| Monday, April 6 | 18 | 83.08 hours |
| Monday, July 6 | 11 | 50.77 hours |
| Monday, October 5 | 5 | 23.08 hours |
The period from December 19, 2026 to January 1, 2027 ends in 2027, so it counts toward the next year’s allowance.
Waiting periods and probation
- Accrues from day one, usable later: the balance builds from your start date but can’t be used until, say, 90 days in.
- Accrual starts later: nothing is earned until a waiting period ends.
- Front-loaded after probation: a prorated block is added once the waiting period ends.
- Some state and local paid sick leave laws require accrual to begin on the first day of work even when use can be delayed.
Leaving partway through a period
The last period works the same way in reverse. If you leave on Wednesday, September 16, 2026, in a period running September 12 to 25, you worked 5 of its 14 days. Prorated, that is 120 ÷ 26 × 5 ÷ 14 ≈ 1.65 hours; excluded, it is nothing. Whether those hours are paid out is a separate question for the payout policy.
Short months and leap years
Semi-monthly periods split each month at the 15th, so the second half of February is 13 days — or 14 in a leap year. Starting on February 20 with 5 hours a period, prorating by days gives 5 × 9 ÷ 13 ≈ 3.46 hours in 2026 but 5 × 10 ÷ 14 ≈ 3.57 hours in 2028. A day-based proration always depends on the calendar, not just the start date.
PTO for New Hires FAQ
- Do new employees accrue PTO from their first day?
- Many do, even if they can’t use it right away; others start accruing after a waiting period. The handbook or offer letter says which.
- How much PTO will I have after 90 days?
- At 120 hours a year paid biweekly, starting on the first day of a pay period, 90 days covers 6 full periods: 6 × 4.62 ≈ 27.69 hours.
- Why was my first PTO accrual smaller than the rest?
- You probably started partway through the first pay period, and your employer prorated it.
- Does PTO accrue during unpaid leave?
- Usually not under a per-hour policy, because no hours are worked. Per-period policies vary; some pause accrual during unpaid leave.
- Is a partial pay period prorated by days or by hours?
- Either, depending on the employer. Calendar days, scheduled workdays, and hours worked can all give slightly different answers for the same partial period.
