PTO Accrual Calculator
Calculate Paid Time Off (PTO) accruals per paycheck, annual hours, and monetary value.
How to Use the PTO Accrual Calculator
Paid Time Off (PTO) is one of the most valuable components of employee total compensation packages. Most modern employers use an accrual-based leave model rather than granting an upfront lump sum of days on January 1st. In an accrual system, workers earn a fractional number of vacation and sick leave hours with each passing pay stub.
Formula and Calculation Methodology
- Annual Pay Periods: 26 for bi-weekly, 24 for semi-monthly, 52 for weekly, 12 for monthly
- Accrual Rate: Exact decimal hours deposited into employee leave bank on each payroll cycle
- Cash Value: Total accumulated PTO hours multiplied by employee contract hourly rate
Understanding your exact accrual rate per paycheck is essential when planning future vacations, parental leave, or tracking severance payouts. Because payroll systems round accruals to two or four decimal places (e.g. 4.6154 hours per bi-weekly paycheck for a 15-day policy), this calculator eliminates guesswork and tracks both hours and equivalent cash value under state payout laws.
PTO Accrual Rates by Annual Allowance (Bi-Weekly 26 Pay Periods)
| Annual Vacation Days | Total Annual Hours | Bi-Weekly Accrual Rate | Weeks to Accrue 1 Day (8h) |
|---|---|---|---|
| 10 Days (2 Weeks) | 80 Hours | 3.08 Hours / pay period | 5.2 Weeks (2.6 paychecks) |
| 15 Days (3 Weeks) | 120 Hours | 4.62 Hours / pay period | 3.5 Weeks (1.7 paychecks) |
| 20 Days (4 Weeks) | 160 Hours | 6.15 Hours / pay period | 2.6 Weeks (1.3 paychecks) |
| 25 Days (5 Weeks) | 200 Hours | 7.69 Hours / pay period | 2.1 Weeks (1.0 paycheck) |
| 30 Days (6 Weeks) | 240 Hours | 9.23 Hours / pay period | 1.7 Weeks (< 1 paycheck) |
Frequently Asked Questions
Are employers legally required to pay out unused PTO when you quit?
It depends on state law. In states like California, Colorado, Illinois, and Montana, earned PTO is legally considered earned wages and must be paid out in full upon separation. In other states, company policy dictates whether PTO is forfeited.
What is the difference between bi-weekly and semi-monthly PTO accrual?
Bi-weekly pay schedules occur 26 times per year (every other week), resulting in smaller accruals per check. Semi-monthly occurs 24 times per year (twice a month), meaning each paycheck accrues a slightly higher number of hours.
What is a PTO rollover cap or ‘use-it-or-lose-it’ policy?
Many companies establish a maximum ceiling on accrued PTO hours or require employees to use vacation days before the end of the calendar year to prevent unbudgeted corporate liabilities.
