PTO Accrual Calculator
Calculate vacation accrual rates and PTO liability.
About this calculator
Paid time off is a real liability on a company's books, not just a scheduling nicety, and this calculator turns an accrual policy into both per-pay-period accrual amounts and dollar figures. It divides the annual PTO days you enter by the number of pay periods per year to get accrual per period (in both days and hours, assuming an 8-hour day), then values a day of PTO at the employee's daily rate — annual salary divided by 260 standard working days. Multiplying the current PTO balance by that daily rate gives the accrued liability sitting on the books for one employee, and multiplying by employee count projects the total company-wide liability if everyone cashed out or left simultaneously — a number finance and HR teams use for balance-sheet accrual accounting and for understanding a hidden cost that grows every pay period whether or not anyone takes time off.
The max liability figure shows the worst case if every employee carried the maximum allowed balance into the books. This model assumes every employee has an identical salary and PTO policy; a real organization's total liability will differ once you account for the actual distribution of salaries, tenure-based accrual rates, and use-it-or-lose-it versus unlimited carryover policies across the workforce.

Frequently Asked Questions
Why do I need both a days figure and an hours figure for accrual per period?
Payroll systems record PTO accrual differently depending on how they track time — some track whole or fractional days, others track hours directly, especially for hourly or shift-based employees. Showing both, with hours calculated as days times 8, lets you match whichever unit your actual payroll or HR system uses without doing the conversion by hand.
What does the total company PTO liability actually represent?
It's the dollar value of every current PTO balance across your employee count, calculated as if the whole workforce were paid out today at their current balance and salary-derived daily rate. It's a standard accrual-accounting figure companies track because unused PTO is a real financial obligation, not free — it either gets paid out on separation in many states or must eventually be granted as time off.
How does raising the pay periods per year change the accrual per period?
The same annual PTO allotment gets divided across more, smaller chunks — going from 24 semi-monthly periods to 26 biweekly periods spreads the identical annual total slightly thinner per paycheck, so accrual per period drops proportionally even though the total PTO earned across the year doesn't change.
Why does the calculator use 260 working days to find the daily rate instead of 365?
Salary is meant to be earned over actual working days, not calendar days, and 260 approximates 52 weeks of a standard 5-day work week (52 × 5). Using 365 would understate the value of a PTO day by counting weekends the employee wasn't scheduled to work anyway.
