Leave Accrual Rate Calculator
The Leave Accrual Rate Calculator helps employees and HR professionals understand how leave time accumulates throughout the year. Different organizations use different accrual methods - some accrue leave per pay period, others per hour worked, and some grant leave upfront. Understanding your accrual rate is essential for planning time off. This calculator shows exactly how much leave you earn each pay period and projects your balance at any point in the year. Whether you have an annual entitlement that accrues monthly, an hourly accrual rate, or a per-pay-period system, this tool provides clarity on your leave accumulation.

Example scenarios
UK Employee - 25 Days Annual
Monthly paid employee with 25 days annual leave
Why it matters: 25 days ÷ 12 months = 2.08 days accrued per month.
US Employee - Bi-weekly Pay
Employee earning 15 days with bi-weekly pay
Why it matters: 15 days ÷ 26 pay periods = 0.58 days (4.62 hours) per period.
Hourly Accrual - Part Time
Hourly worker earning PTO per hour worked
Why it matters: 0.0462 × 60 hours = 2.77 hours per period, ~72 hours/year (9 days).
Frequently asked questions
What is a typical PTO accrual rate?
In the US, 10-15 days (80-120 hours) per year is common for new employees. This translates to about 0.0385-0.0577 hours per hour worked, or 3-5 hours per bi-weekly pay period.
Do I accrue leave while on leave?
In most cases, yes. Paid time off is typically treated as hours worked for accrual purposes. Check your company policy for specifics.
What happens to unaccrued leave if I leave mid-year?
Most employers pay out accrued but unused leave. If you received leave upfront, you may owe back any used but unearned leave.
How does accrual work with unlimited PTO?
Unlimited PTO policies do not use accrual - there is no balance to track. This is one reason some prefer traditional accrual systems.
