Understanding your PTO accrual rate is essential for employees who want to manage their time off effectively and for HR professionals tasked with scheduling and payroll. This calculator helps you determine exactly how much paid time off you earn with each pay period, based on your company's policy and work schedule.
Whether you work in the US or the UK, knowing your accrual rate can help you plan vacations, personal days, and other leave types more efficiently. It also ensures that HR teams can maintain accurate records and avoid miscalculations that could affect payroll or employee satisfaction.
How the calculation works
PTO accrual is typically calculated based on total annual PTO hours divided by the number of pay periods in a year. For example, if an employee earns 20 days of PTO per year and is paid monthly, they accrue approximately 1.67 days per pay period (20 ÷ 12). If paid biweekly, they would accrue about 0.77 days per pay period (20 ÷ 26).
Our calculator uses the formula: (Total Annual PTO Hours ÷ Number of Pay Periods) = Accrued PTO per Pay Period. It adjusts for both salaried and hourly employees and supports different accrual models, including immediate accrual or a staggered ramp-up period. The tool accounts for part-time hours and can calculate accruals based on the employee’s scheduled work hours versus full-time equivalents.
