The Formula

PTO accrual per pay period = Annual entitlement / pay periods per year Front-loaded PTO = Granted on January 1 (no accrual lag) Sick leave (state-mandated) = 1 hour earned per 30 hours worked (typical) Prorated entitlement on hire = (Entitlement / 365) × days remaining in plan year Closing balance = Opening + Accrued − Taken − Forfeited (above cap)

Carry-over rules vary by state and policy. Many US employers cap carry-over at 40 to 80 hours; California prohibits use-it-or-lose-it on accrued vacation; New York requires 56 hours of paid sick leave for larger employers.

Worked Example

Example: Employee hired April 1 in Texas, 80 PTO hours per year accrued bi-weekly, used 24 hours by December 31

Annual entitlement80 hours
Pay periods per year26 (bi-weekly)
Accrual per pay period80 / 26 ≈ 3.08 hours
Pay periods worked (Apr–Dec)20
Accrued PTO20 × 3.08 ≈ 61.5 hours
PTO taken24 hours
PTO balance at December 31 ≈ 37.5 hours

Three common leave categories in the US

Most US employers maintain a few separate leave buckets. PTO (Paid Time Off) is the modern, combined approach — vacation, personal, and minor sick days share one balance. State-mandated paid sick leave (CA, CO, NJ, NY, OR, WA, AZ, MA, RI, VT, MD, DC, and many cities) accrues separately at 1 hour per 30 worked. FMLA leave is unpaid, job-protected leave for qualifying medical or family reasons. Bereavement, jury duty, military (USERRA), and parental leave are usually tracked as separate categories.

Accrual vs front-loading

Accrual-based PTO grants hours each pay period — fair when employees leave mid-year because the prorated balance is automatic. Front-loaded PTO grants the full annual entitlement on January 1 (or anniversary date) — simpler for employees but creates over-grant exposure if someone leaves in February. State paid-sick-leave laws often allow either model with restrictions; California's Healthy Workplaces, Healthy Families Act, for example, requires either accrual-style or 24-hour minimum frontload.

Carry-over rules and use-it-or-lose-it

Most US employers cap PTO carry-over at 40 to 80 hours. Use-it-or-lose-it policies are valid in many states but prohibited in California, Colorado, Nebraska, North Dakota, and Montana for accrued vacation — those states treat earned vacation as wages that cannot be forfeited. Where carry-over is allowed, the cap should be in writing in the handbook and consistently enforced. Excess balances at year end are typically capped, encashed, or rolled forward depending on policy.

How Peoplifi handles leave

Peoplifi accrues PTO each pay period using the configured rate, enforces caps and carry-over rules automatically, separates state-mandated sick leave from PTO so it accrues correctly per jurisdiction, prorates new-hire entitlements, and connects the balance to the mobile self-service app so employees always see live balances. The platform also splits leave across plan years when a leave request spans the year-end boundary.

Frequently Asked Questions

How much PTO is standard for US employees?

There is no federal minimum for PTO. Common ranges: 10 days for new hires, 15 days at 5 years of service, 20+ days for senior tenure. State-mandated paid sick leave (typically 5 to 10 days per year) is separate from PTO in most jurisdictions.

How is accrual calculated?

Most commonly: annual entitlement ÷ pay periods per year (26 for bi-weekly, 24 for semi-monthly, 12 for monthly). State sick-leave laws often require 1 hour earned per 30 hours worked.

Can unused PTO carry forward in the US?

Depends on state and policy. California, Colorado, Nebraska, North Dakota, and Montana prohibit forfeiture of accrued vacation. Most other states allow caps and use-it-or-lose-it if disclosed in writing. Federal law does not require carry-over.

Do we have to pay out unused PTO at termination?

California, Colorado, Montana, North Dakota, Nebraska, Illinois (effective 2024), and several others require payout of accrued PTO at separation. Other states default to whatever the written policy says. Always check state law before issuing the final paycheck.
