How PTO accrual works
Most employers let you earn paid time off gradually. Your accrual rate is the number of hours added to your balance each pay period.
\[ \begin{gathered} \text{annual PTO hours} = \text{PTO days} \times 8 \times \left( \dfrac{\text{your weekly hours}}{40} \right) \\ \text{hours per pay period} = \dfrac{\text{annual PTO hours}}{\text{number of pay periods}} \\ \text{balance} = \text{hours per pay period} \times \text{pay periods worked} - \text{hours used} \end{gathered} \]
| PTO per year | Weekly | Biweekly | Semimonthly | Monthly |
|---|---|---|---|---|
| 10 days (80 h) | 1.54 h | 3.08 h | 3.33 h | 6.67 h |
| 15 days (120 h) | 2.31 h | 4.62 h | 5.00 h | 10.00 h |
| 20 days (160 h) | 3.08 h | 6.15 h | 6.67 h | 13.33 h |
| 25 days (200 h) | 3.85 h | 7.69 h | 8.33 h | 16.67 h |
Common PTO policies
Some employers accrue hours every paycheck, others add the full amount on January 1 (front-loading) or after a waiting period. Many put a cap on the balance, often 1.5 times the yearly amount, and some pay out unused PTO when you leave. Payout is required in some states, such as California, and not in others, so read your handbook. Federal law does not require paid vacation. PTO that is a separate sick leave bank may follow state or city laws.
How much vacation do Americans get?
The Bureau of Labor Statistics reports that private-sector workers average about 11 paid vacation days after one year of service, 15 after five years, 17 after ten and 20 after twenty. Holidays are counted separately. The table below the results shows these benchmarks. If your PTO is below these averages, it is a point worth raising at your next review.
PTO accrual calculator: rates by pay schedule
The accrual rate depends on how often you are paid. For 15 days a year, which is 120 hours, here are the results.
| Pay schedule | Periods per year | Hours per period |
|---|---|---|
| Weekly | 52 | 2.31 |
| Biweekly | 26 | 4.62 |
| Semi-monthly | 24 | 5.00 |
| Monthly | 12 | 10.00 |
So the same policy gives different numbers per paycheck. In fact, the total stays 120 hours a year.
PTO accrual calculator: how to plan your time off
A little planning stretches your balance. First, check your accrual rate and your cap. Then map the long weekends and holidays. Next, estimate the balance you will have on the date of your trip. Finally, request time early, because popular weeks fill up fast.
For example, at 4.62 hours per paycheck, you earn about 9.24 hours a month. So a full week off (40 hours) needs about four months of accrual. Also, avoid hitting the cap, since you stop earning once it is full.
PTO accrual calculator: related planning tools
To plan around dates, use the business days calculator and the federal holidays calendar. To see how pay changes, open the paycheck calculator. Finally, log your hours with the time card calculator.
This result is an estimate. Your employee handbook is the official source for your policy.
PTO accrual calculator: cap, carryover and payout
Three rules shape your real balance. First, the cap stops accrual once you reach a set limit, such as 180 hours. Second, carryover rules decide how much unused time rolls into the next year. Third, payout rules decide whether you are paid for unused time when you leave. In some states, accrued vacation counts as earned wages, so the payout is required.
Therefore, read your handbook before you plan. In addition, ask HR how new hires accrue during the first 90 days.
In short, a clear PTO accrual rule keeps surprises away, and a quick PTO accrual check each quarter keeps your plan on track.
3 real-life examples
15 days a year, paid biweekly
\( 15 \times 8 = 120 \) hours a year. \( \dfrac{120}{26} = \) 4.62 hours per paycheck. After 13 paychecks, you have earned 60 hours, or 7.5 days.
20 days a year, paid twice a month
\( 20 \times 8 = 160 \) hours. \( \dfrac{160}{24} = \) 6.67 hours per paycheck. After 6 paychecks you have 40 hours, one full work week.
Part-time at 30 hours a week with 10 days
\( 10 \times 8 \times \left( \dfrac{30}{40} \right) = 60 \) hours a year. Paid monthly, that is 5 hours a month, so after 6 months your balance is 30 hours.
