How PTO accrual works
Most employers use an accrual-based PTO system where employees earn time off gradually as they work, rather than receiving it all at once. Accrual rate = annual PTO hours / annual pay periods. For 15 days (120 hours) on a biweekly pay schedule (26 pay periods): 120 / 26 = 4.615 hours per paycheck. On a semi-monthly schedule (24 periods): 120 / 24 = 5 hours per period. After 10 pay periods, the employee has accrued 46.15 hours (about 5.77 days). The accrual approach gives employers flexibility to avoid paying out large balances to employees who leave early in the year.
Accrual methods — hourly vs. per period vs. annual grant
Per-period accrual: a fixed amount of PTO is added to the employee's balance each pay period, regardless of hours worked. This is simple and common for salaried employees. Hourly accrual: PTO accrues at a rate per hour worked (e.g., 0.0577 hours of PTO per hour worked = 120 hours/2,080 hours). This method is fairer for part-time employees and more common in hourly-wage environments. Annual lump sum (front-loading): all PTO for the year is granted on a specific date (January 1 or hire anniversary). This is simpler to administer and employees appreciate having the full balance immediately, but creates a liability problem: an employee who uses all their PTO and then resigns in February has been paid for more PTO than they earned.
Accrual caps and use-it-or-lose-it policies
Many employers set a maximum accrual cap — often 1.5x or 2x the annual PTO amount. Once the cap is reached, the employee stops accruing until they use some PTO. This prevents large balances from accumulating and limits the employer's payout liability when employees leave. Use-it-or-lose-it policies — where unused PTO expires at year-end — are legal in most US states but are banned in California, Colorado, and a few others. In California, accrued PTO is considered earned wages and cannot be forfeited by policy. Employers in these states must either allow unlimited carryover or pay out unused PTO at separation.
PTO payout at separation
Whether your employer must pay out unused PTO when you leave depends on your state. States that require PTO payout at termination: California, Colorado, Illinois, Louisiana, Massachusetts, Nebraska, North Dakota, and a few others. Most other states leave it to company policy — many employers pay out accrued PTO regardless, either by policy or because they want to attract and retain employees. To calculate your expected payout: (hourly rate) × (accrued PTO hours). On a $75,000 salary ($36.06/hour) with 80 hours of accrued PTO: payout = $36.06 × 80 = $2,885 (before taxes).
