Estimate how many paid-time-off hours and days you will have at the end of your leave year. Choose an annual allowance or a per-pay-period accrual rate.
Projected balance = current balance + future accrual − planned time off.
With an annual allowance, the remaining share of the leave year determines future accrual.
Example: 40 current hours + 30 future hours − 16 planned hours = 54 hours.
When your employer gives a fixed amount each pay period, multiply that amount by the eligible periods remaining.
Weekly payroll usually has 52 periods, biweekly 26, semimonthly 24 and monthly 12. Confirm the exact calendar and rules with your employer.
Multiply the PTO hours earned each pay period by the number of eligible pay periods. Add any balance you already have, then subtract time already used or planned.
Yes, if your employer permits borrowing future PTO. A negative result means planned use is greater than your current balance plus expected future accrual.
The U.S. Department of Labor says the Fair Labor Standards Act does not require payment for time not worked, including vacation, sick leave or holidays. Employer policies and state or local rules may apply. See the Department of Labor guidance.
Federal annual leave follows specific service-based rules. The U.S. Office of Personnel Management publishes the official annual leave accrual rates. This calculator does not automatically apply those rules.
