How it works

Our PTO calculator divides your annual paid time off allowance by the number of pay periods in your year to determine exactly how many hours you accrue each paycheck. It then multiplies by the number of periods you've worked to show your total accrued time, converts hours to workdays, and factors in any existing balance or accrual cap.

The Formula

The basic PTO accrual formula is:

PTO Per Pay Period = Annual PTO Hours ÷ Number of Pay Periods
Total Accrued = PTO Per Period × Periods Worked
Days Off = Total Hours ÷ Hours Per Workday

PTO accrual methods

Employers in the United States use three primary methods to calculate paid time off. Understanding which method your company uses is essential for accurate planning.

Method 1: Per Pay Period Accrual

The most common method. Your annual PTO allocation is divided evenly across all pay periods. You earn a fixed number of hours each paycheck regardless of hours worked.

Pay Frequency Periods/Year 80 hrs/yr 120 hrs/yr 160 hrs/yr
Weekly521.54 hrs2.31 hrs3.08 hrs
Biweekly263.08 hrs4.62 hrs6.15 hrs
Semi-monthly243.33 hrs5.00 hrs6.67 hrs
Monthly126.67 hrs10.00 hrs13.33 hrs

Method 2: Per Hour Worked

Common for hourly and part-time employees. You earn PTO based on actual hours worked. Typical rates range from 1 hour of PTO per 20-40 hours worked, depending on state laws and employer policy.

Method 3: Annual Lump Sum (Front-loaded)

Your full PTO bank is available on your hire date anniversary or January 1st. While simple to administer, this method can create complications if you leave mid-year. Your employer may recoup PTO used but not yet "earned."

Example Calculation

Let's walk through a real-world example:

  • Annual PTO: 120 hours
  • Pay frequency: Biweekly (26 pay periods)
  • Periods worked so far: 13 (half a year)
  • Current balance: 8 hours (carried over)
  • Workday length: 8 hours

Results:

  • Accrual per paycheck: 120 ÷ 26 = 4.62 hours
  • Total accrued in 13 periods: 4.62 × 13 = 60.06 hours
  • Equivalent days: 60.06 ÷ 8 = 7.51 workdays
  • Projected balance: 8 + 60.06 = 68.06 hours

Accrual caps

Many employers set maximum PTO balances (also called accrual caps or ceilings). Once you reach the cap, accrual stops until you use some time. Common caps range from 1.5× to 2× your annual accrual:

  • 120 hours/year with 1.5× cap = maximum balance of 180 hours
  • 120 hours/year with 2× cap = maximum balance of 240 hours

This policy encourages regular time off and reduces employer liability. If you're approaching your cap, it's wise to schedule time off to avoid losing accrual.

PTO Calculator — FAQ

How do I calculate my PTO accrual rate?
Divide your total annual PTO hours by the number of pay periods in a year. For biweekly pay (26 periods), if you get 120 hours/year: 120 ÷ 26 = 4.62 hours per pay period. For weekly pay (52 periods): 120 ÷ 52 = 2.31 hours per paycheck.
What is a typical PTO accrual rate?
The average American worker receives 10-15 PTO days per year (80-120 hours) for their first 1-5 years. After 5+ years of tenure, this often increases to 15-20 days (120-160 hours). Senior employees with 10+ years may receive 20-25 days (160-200 hours).
Does PTO accrue during vacation or leave?
In most cases, yes. PTO continues to accrue during paid time off, holidays, and jury duty. However, PTO typically does not accrue during unpaid leave, FMLA leave (varies by employer), or workers' compensation. Check your employee handbook for your employer's specific policy.
What happens to PTO when I hit my accrual cap?
When you reach your employer's maximum PTO balance (accrual cap), you stop earning additional hours until you use some time off. For example, if your cap is 180 hours and you have 180 banked, no more accrues until you drop below 180. This is sometimes called a 'use-it-or-lose-it' cap.
Is PTO the same as vacation time?
Not exactly. PTO (Paid Time Off) is a combined bank covering vacation, sick days, and personal time. Traditional vacation time is separate from sick leave. With PTO, you have more flexibility but must budget for illness. About 63% of US employers now use combined PTO policies rather than separate vacation and sick banks.
Do part-time employees accrue PTO?
Many employers offer prorated PTO to part-time employees. If full-time (40 hrs/week) earns 120 hours/year, a 20 hr/week employee might earn 60 hours/year. Some employers use per-hour-worked accrual instead (e.g., 1 hour PTO per 30 hours worked), which naturally prorates for part-time schedules.
