PTO Accrual Calculator

How PTO accrual works

Paid time off usually builds up over the year instead of landing in your account all at once. Employers use one of three methods. Per pay period accrual grants a fixed number of hours on every paycheck, which fits salaried staff on a steady schedule. Per hour worked accrual earns a small fraction of an hour for each hour on the clock, which suits part-time and variable workers. An annual allotment grants a lump of hours once a year, or spreads it evenly across your pay periods.

Whatever the method, the running balance follows one formula: starting balance plus hours accrued, minus PTO already used. This calculator runs that formula, then holds the result at your rollover cap if you set one.

How to calculate your PTO accrual rate

For a per pay period rate, divide your annual PTO hours by the pay periods in a year. With a 120-hour allotment: biweekly is 120 ÷ 26 = 4.62 hours, semimonthly is 120 ÷ 24 = 5.00 hours, and weekly is 120 ÷ 52 = 2.31 hours. Monthly accrual is 120 ÷ 12 = 10.00 hours.

For a per hour worked rate, divide annual PTO hours by annual hours worked. Full-time work is commonly 2,080 hours a year (40 hours over 52 weeks), so 120 ÷ 2,080 = 0.0577 hours of PTO for each hour on the clock. If you need that total first, add up your hours with the timesheet hours calculator. To turn any hours result into days, divide by your workday length: 120 hours ÷ 8 = 15 days, and 160 hours ÷ 8 = 20 days.

Accrual caps, rollover, and carryover

An accrual cap is the ceiling on your bankable balance. Once you reach it, you stop earning PTO until you use some, so any hours you would have accrued are forfeited. Caps commonly sit at 1.5 to 2 times the annual allotment. This tool shows the hours you would lose to the cap, so the tradeoff is out in the open instead of catching you by surprise.

Rollover (carryover) moves unused hours into the next year, sometimes up to a maximum. Use-it-or-lose-it instead wipes unused hours at year-end. Several states, including California, Colorado, Montana, and Nebraska, treat earned vacation as wages and prohibit use-it-or-lose-it forfeiture, though they may still allow a reasonable cap. Check your state labor rules and your employer handbook for the exact policy.

From accrued hours to a paycheck

PTO is paid at your regular rate, and when it is cashed out it is taxed like ordinary wages. The gross cash value above (available hours times your hourly rate) is a pre-tax figure, so the amount that actually reaches you is smaller after withholding. To see the take-home number, run the balance through the hourly paycheck calculator. When you need to turn PTO hours into real net pay across a whole team, the Payroll Calculator app handles federal, state, and FICA math with per-employee wage-base tracking.
