PTO · Vacation accrual & balance

PTO Accrual Calculator

Turn your annual vacation into per-paycheck and per-hour accrual, track hours earned versus used, and project your year-end balance with carryover caps.

To find your PTO accrual, divide your annual PTO hours by the number of pay periods per year. 15 days (120 hours) paid bi-weekly accrues 4.62 hours per paycheck; your available balance is the starting balance plus accrued hours minus hours used.

How PTO accrual works

Most employers grant paid time off gradually — you accrue a slice of your annual allotment each pay period rather than getting it all on January 1. This calculator turns your annual PTO into a per-paycheck accrual, an hourly accrual rate, and your current available balance after subtracting hours you've already used.

The core formula

Accrual per pay period

Per-period accrual = Annual PTO hours ÷ pay periods per year. Example: 15 days × 8 hours = 120 hours ÷ 26 bi-weekly periods = 4.62 hours per paycheck. After 10 paychecks you'd have accrued 46.2 hours (about 5.8 days).

Accrual per hour worked

Hourly and part-time plans often express accrual as PTO hours earned per hour on the clock: Annual PTO hours ÷ 2,080 (a full-time work-year). So a 120-hour plan accrues about 0.0577 hours of PTO for every hour worked. Enter days or hours above and the calculator shows both.

Days ↔ hours

PTO is tracked in hours by payroll but requested in days by employees. With an 8-hour workday, 1 day = 8 hours, so 40 hours = 5 days. If your standard day is 7.5 hours, adjust the "hours in a full workday" field so day conversions match your employer's.

Use-it-or-lose-it & carryover caps

Some plans cap how many hours roll into the next year. Enter a max carryover to see your projected year-end balance capped accordingly. Note that a few states (like California) prohibit "use-it-or-lose-it" forfeiture of earned vacation — check your local law.

Questions, answered

Frequently asked.

Divide your annual PTO (in hours) by the number of pay periods in a year. For 15 days of PTO at 8 hours a day = 120 hours, paid bi-weekly (26 periods), you accrue 120 ÷ 26 = 4.62 hours per paycheck. Enter your numbers above and the calculator does this instantly and tracks your running balance.
Divide your annual PTO hours by 2,080 (the hours in a full-time work-year). A 120-hour plan earns about 0.0577 hours of PTO per hour worked. This “per hour worked” method is common for hourly and part-time employees, where accrual scales with actual hours on the clock.
It depends on your standard workday — usually 8 hours, so a day of PTO = 8 hours and 40 hours = 5 days. If your company uses 7.5-hour days, set the “hours in a full workday” field to 7.5 so the day conversions match your policy.
Carryover is the maximum PTO you can roll into the next year; anything above the cap is forfeited under a “use-it-or-lose-it” policy. Enter a carryover cap above to see your projected year-end balance limited to it. Some states, including California, bar forfeiture of already-earned vacation.
It depends on the employer. A combined “PTO” bank lumps vacation, personal, and sick time together, while other companies track vacation and sick leave separately (sometimes required by state law). This calculator models a single accruing bank — run it twice if your vacation and sick time accrue at different rates.
Available = starting balance + accrued so far − hours already used. “Accrued so far” is your per-pay-period accrual times the number of pay periods completed this year. The projected year-end figure assumes you finish the year and applies any carryover cap you set.
