PTO Accrual Calculator
A PTO accrual calculator works out how much paid time off you have earned and how much you will have by year end, based on your accrual method (per hour worked, a flat amount per pay period, or an annual allowance), your pay frequency, and the PTO you have already used. Enter your details below to see your current balance, projected year-end balance, payout value, and balance in days.
How PTO accrual works
PTO accrues in one of three ways. Per hour worked: you earn a set fraction of an hour of PTO for every hour on the clock, common for hourly roles. Flat per pay period: you earn a fixed number of PTO hours each paycheck. Annual allowance: you are granted a lump sum for the year that effectively accrues across your pay periods. This calculator supports all three so you can match your employer's policy exactly.
The PTO accrual formula (with example)
For hourly accrual, PTO earned = hours worked × accrual rate per hour. For pay-period accrual, PTO earned = hours per pay period × pay periods completed. Then subtract PTO already used and apply any carryover cap. Example: at 4 hours of PTO per biweekly paycheck, after 9 pay periods you have earned 36 hours; subtract 4 hours used and you have 32 hours, which is 4 days at an 8-hour workday.
Per hour worked vs per pay period
Use hourly accrual when your policy ties PTO to hours actually worked, so part-time and overtime hours change what you earn. Use per-pay-period accrual when everyone earns the same PTO each paycheck regardless of hours. Salaried employees are almost always per pay period or on an annual allowance.
How to calculate a PTO payout
A PTO payout, or cash-out, converts unused PTO to cash: PTO payout = payable PTO hours × hourly wage. Example: 32 unused hours × $25 = $800 before taxes. Many states require payout of accrued, unused PTO when you leave a job, but policies vary, so check yours.
Converting PTO hours to days
Divide your PTO hours by your standard workday: PTO days = PTO hours ÷ hours per workday. 32 hours ÷ 8 = 4 days. The calculator shows both so you can plan in whichever unit your employer uses.
Prorated PTO for new hires
New hires rarely get a full year of PTO. Prorate it by counting the pay periods (or hours) the employee will actually work: prorated PTO = annual allowance ÷ pay periods × pay periods remaining. The calculator does this when you enter a partial year.
Accrued vs. available PTO
Accrued PTO is the total time off you have earned to date. Available PTO is what you can actually book right now, which may be lower if some accrued time is already requested, pending, or held below a cap. This calculator shows your accrued and projected balances; check your HR system for the bookable, available figure.
Do you accrue PTO while on leave?
It depends on the leave type and your policy. Many employers pause accrual during unpaid leave and keep accruing during paid leave, but rules vary. Hours-based accrual naturally stops when no hours are worked; per-pay-period accrual often continues unless your policy says otherwise.
Does overtime count toward accrual?
Under hourly accrual, overtime hours usually earn PTO at the same rate as regular hours unless your policy excludes them. Under per-pay-period or annual-allowance plans, overtime has no effect because accrual is not tied to hours worked.
Part-time PTO
Part-time employees on hourly accrual earn PTO in proportion to the hours they work, so fewer hours mean less PTO. On a per-pay-period plan, part-timers often get a prorated amount based on their schedule. Enter the hours that match your situation to see the right balance.
Carryover, rollover, and use-it-or-lose-it
Carryover (rollover) is the PTO you can move into the next year. Some policies cap it; strict use-it-or-lose-it policies reset unused PTO to zero. A growing number of US states restrict use-it-or-lose-it and treat accrued PTO as earned wages, so check your state and handbook before assuming you will lose a balance.
