Estimate PTO accrual, balance, and projected year-end hours
This calculator supports two common policy structures: an annual PTO allowance distributed across pay periods, or PTO earned as a rate for each hour worked. Add carryover, subtract PTO already used, and apply an optional balance cap.
Formulas
Pay-period accrual
PTO per pay period = annual PTO hours ÷ pay periods per year
Current accrual multiplies that amount by completed pay periods.
Hourly accrual
PTO earned = hours worked × PTO hours earned per hour
Use the accrual rate stated by your employer or payroll system.
Worked example
A 120-hour annual allowance paid across 24 periods accrues 5 hours per pay period. After six completed periods, 30 hours have accrued before carryover and PTO usage are applied.
Important policy limitation
This is a policy-math estimator, not a statement of employment law or your official PTO balance. Employer rules can differ on waiting periods, frontloading, caps, carryover, forfeiture, and payout. Verify the result against your written policy and payroll record.
