Your payslip shows a PTO figure that grows every payday. This works out what that number should be.

Pick whether you earn a set amount each pay period or build hours as you work, and the calculator gives you the rate per period, week, month, and year.

Two weeks is 80 hours or 10 days. Three weeks is 120 hours or 15 days.

hours worked

Common rates are 1 hour per 30 worked or 1 per 40. Your handbook or state law sets this.

Advanced options

Some employers stop your accrual at a set number of hours per year.

This is an estimate. Your employer’s payroll system holds the official figure. Accrual rules depend on your company policy and your state.

The two PTO accrual methods

Employers use one of two PTO accrual methods.

A set amount each pay period.

You get the same number of hours every payday, no matter how much you worked. Salaried staff usually fall here.

An amount per hour worked.

Your PTO grows with your hours. Part time and hourly staff usually fall here, and most state sick leave laws use this method.

Your payslip tells you which. If the PTO line adds the same figure every period, you are on the first system. If it moves with your hours, you are on the second. The calculator covers both, so pick your method at the top and the fields change to match.

How to calculate PTO accrual per pay period

Divide your yearly allowance by your number of pay periods.

Annual PTO hours / pay periods per year = hours per period

Your pay schedule sets the number of periods:

Pay schedulePeriods per year
Weekly52
Every two weeks26
Twice a month24
Monthly12

Two weeks of PTO is 80 hours. On a biweekly schedule that is 3.08 hours each payday. Paid monthly, the same 80 hours becomes 6.67 hours.

Note that biweekly and semi-monthly are not the same. Biweekly pays every 14 days, giving 26 periods. Semi-monthly pays on set dates such as the 15th and the last day, giving 24. The accrual per period differs even when the yearly total matches.

How to calculate PTO accrual per hour worked

Divide the hours you work by your accrual ratio.

Hours worked / accrual ratio = PTO hours earned

A common ratio is one hour of PTO for every 30 hours worked. Someone working 80 hours in a pay period earns 2.67 hours of PTO.

Switch the tool to hourly mode to run a PTO accrual calculation based on hours worked rather than a fixed amount per payday.

Ratios you will see:

  • 1 per 30 worked gives 3.33 percent, common for state sick leave
  • 1 per 40 worked gives 2.5 percent
  • 1 per 26 worked gives about 3.85 percent, roughly two weeks a year

Whether overtime counts toward your hours worked depends on your policy. Some employers count every hour. Others count scheduled hours only.

Converting between days and hours

Payroll works in hours. Handbooks often talk in days.

PTO days x hours in your workday = PTO hours

Ten days on an 8 hour schedule is 80 hours. The same ten days on a 7.5 hour schedule is 75 hours.

Always use your real shift length. Getting this wrong throws off every figure that follows.

What changes your PTO accrual rate

Several things change your PTO accrual rate.

Length of service.

Many employers raise your rate over time. A common pattern is two weeks in year one, three weeks after five years, four weeks after ten.

Employment type.

Part time staff often accrue at the same ratio but earn less because they work fewer hours. Some employers exclude part time staff entirely.

A waiting period.

New hires often accrue from day one but cannot use anything for the first 30 to 90 days.

Unpaid leave.

Time off without pay usually pauses accrual, especially on per hour systems.

A cap.

Once you hit the maximum balance, accrual stops until you use some time.

PTO accrual caps and carryover

These two rules get confused, so here is the difference.

A cap limits how much you can hold at once. When you reach it, you stop earning. You keep what you have.

Carryover rules decide what happens at year end. Some employers move your whole balance forward. Some move only part of it. Some reset it to zero.

A reset is called a use it or lose it policy. Some states ban it outright because they treat earned vacation as wages you already worked for. Others allow it as long as the policy is written and employees were told.

Check your handbook for both. They are usually in the same section.

Frequently asked questions

How does a PTO accrual calculator work?

It divides your yearly PTO hours by your number of pay periods. Eighty hours a year paid every two weeks gives 3.08 hours per period. If you accrue per hour worked instead, it divides your hours worked by your accrual ratio.

How much PTO do I earn per pay period with two weeks a year?

Two weeks is 80 hours. Paid every two weeks that is 3.08 hours per period. Paid twice a month it is 3.33 hours. Paid monthly it is 6.67 hours.

What is a normal PTO accrual rate?

Two weeks a year is common for new employees in the United States, which is 80 hours. Many employers raise this with length of service, reaching three or four weeks after several years.

How does PTO accrual work for hourly employees?

You earn PTO as you work. A common rate is one hour of PTO for every 30 or 40 hours worked. Work 80 hours at a 1 per 30 rate and you earn 2.67 hours of PTO.

What does 1 hour per 30 hours worked mean?

It means you earn one hour of paid time off for every 30 hours you work, which is 3.33 percent of your hours. Someone working full time all year earns about 69 hours.

Is biweekly the same as semi-monthly?

No. Biweekly pays every 14 days, giving 26 pay periods a year. Semi-monthly pays on set dates, giving 24 periods. Your accrual per period differs even when your yearly total is the same.

Does overtime count toward PTO accrual?

It depends on your employer. Some count every hour you work including overtime. Others count only your scheduled hours. Your handbook says which.

When does PTO start accruing for a new employee?

Most employers start accrual on your first day but add a waiting period of 30 to 90 days before you can use any of it. Some delay accrual itself until the waiting period ends.
