PTO Accrual Calculator
Calculate Vacation Time Instantly
If you work for a company that offers Paid Time Off (PTO), you probably do not get all of your vacation days on January 1st. Instead, you have to "earn" your vacation slowly throughout the year. Every time you work a shift or complete a pay period, a little bit of vacation time is added to your account.
This system is called PTO accrual. While it is fair, it can be very frustrating to figure out exactly how much time you actually have. Can you take a week off in May? Do you have enough hours saved up for a long weekend in October?
Instead of guessing, use this free PTO accrual calculator. Whether you are an employee planning a family trip, or an HR manager managing timesheets, this tool will perfectly calculate PTO accrual instantly.

How Does PTO Accrual Work?
If you are wondering, "how does PTO accrual work?", it is simply a drip system for your vacation.
"Accrue" is just a fancy word that means "to grow or build up over time." Instead of giving you 80 hours of vacation at the start of the year, your employer drips a few hours into your PTO bank every single time you get a paycheck.
For example, if you get paid every two weeks (bi-weekly), there are 26 pay periods in a year. If your company promises you 80 hours of vacation a year, they will drip roughly 3.07 hours of PTO into your account during each of those 26 pay periods.
Companies do this to protect themselves. If they gave you 80 hours on day one, you could take a two-week vacation in January and then quit your job in February. Accrual ensures you only take vacation time that you have actually worked hard to earn.
How to Use This PTO Calculator
We built this accrued PTO calculator to be as simple as possible. You do not need to look at complicated spreadsheets. Just follow these steps:
- Enter your Annual PTO Allowance: How much total vacation time does your contract promise you per year? You can enter this number in days or hours.
- Select your Pay Frequency: How often does your boss pay you? Choose weekly, bi-weekly (every two weeks), semi-monthly (twice a month), or monthly.
- Enter Current Pay Period: Which paycheck are you on right now? (For example, if you get paid monthly and it is the end of March, you are on pay period 3).
Once you enter these three details, the vacation time calculator will show you exactly how many hours you earn per paycheck, and the total amount of vacation you have saved up right now.
How to Calculate Accrued PTO (The Manual Formula)
If you are an employer setting up a new payroll system, or an employee who just likes to double-check the math, you might want to know how to calculate accrued PTO by hand.
To find your PTO accrual rate calculator formula, you just need two numbers: your total annual vacation hours, and the total number of pay periods in a year.
The Simple Formula:
Annual PTO Hours ÷ Number of Pay Periods = Accrual Rate Per Paycheck
Let's do a real math example.
Imagine you are promised 3 weeks of vacation a year. You work a standard 40-hour week. Therefore, your total annual PTO is 120 hours (3 weeks × 40 hours). You get paid bi-weekly, which means you get 26 paychecks a year.
- Total PTO: 120 hours
- Total Pay Periods: 26
- The Math: 120 ÷ 26 = 4.615
- The Result: You accrue exactly 4.615 hours of PTO on every single paycheck.
Now, if you want to calculate PTO hours for a specific date, you just multiply that rate. If it is your 10th paycheck of the year, you multiply 4.615 by 10. You currently have 46.15 hours saved up.
Standard PTO Accrual Rates by Pay Period
To save you some math, here is a quick cheat sheet. If your company offers a standard 2 weeks (80 hours) of vacation, here is exactly what you should see on your pay stub depending on how often you get paid:
- Weekly (52 paychecks): You earn 1.53 hours per check.
- Bi-Weekly (26 paychecks): You earn 3.07 hours per check.
- Semi-Monthly (24 paychecks): You earn 3.33 hours per check.
- Monthly (12 paychecks): You earn 6.66 hours per check.
PTO Hours to Days Calculator (Quick Chart)
Most human resources software tracks your time off in exact hours. But humans do not plan vacations in hours; we plan them in days.
People constantly ask questions like, "how many days is 20 hours of PTO?"
Assuming you work a standard 8-hour workday, you can use this quick PTO hours to days calculator chart to translate your pay stub into actual days off.
| Total PTO Hours Earned | Equivalent Days Off | What it means for you |
|---|---|---|
| 8 Hours | 1 Day | A long weekend (Friday off). |
| 20 Hours | 2.5 Days | A half-week of vacation. |
| 40 Hours | 5 Days | One full work week off. |
| 80 Hours | 10 Days | Two full work weeks off. |
| 120 Hours | 15 Days | Three full work weeks off. |
To do this math yourself, simply take your total PTO hours and divide them by 8 (or however many hours you normally work in a single shift).
How to Calculate Accrued Vacation Pay (PTO Payouts)
What happens to all those hours you saved up if you quit your job or get fired? Do they just disappear?
In many U.S. states, your earned PTO is legally considered part of your wages. If you leave the company, your employer must write you a check for the unused vacation time. This is where our tool acts as a PTO payout calculator.
If you want to know how to calculate accrued vacation pay, the math is very straightforward. You multiply your unused PTO hours by your normal hourly wage.
Example of a PTO Payout:
Let's say you look at our vacation accrual calculator and see you have 35 hours of unused PTO. Your current salary breaks down to $25 an hour.
- 35 hours × $25 = $875.00
Your final paycheck from the company should include an extra $875 for your unused vacation time.
*Important Note: PTO payouts are often taxed at a higher "supplemental" tax rate, similar to bonuses. If you want to know exactly how much of that payout you get to keep after taxes, you can use our gross up calculator to estimate the tax burden.*
Furthermore, the U.S. Department of Labor (DOL) does not mandate PTO payouts federally. It is entirely based on state law. States like California and Massachusetts require it by law, while others leave it up to company policy. Always check your employee handbook.
Frequently Asked Questions
Is PTO accrued based on hours worked?
It depends on your company's policy. Most salaried employees accrue a flat amount of PTO every pay period, regardless of whether they worked 35 or 45 hours that week. However, many hourly part-time workers accrue PTO strictly based on hours worked (for example, earning 1 hour of PTO for every 30 hours they clock in).
What is the difference between vacation time and PTO?
Historically, companies offered separate buckets for "vacation days" and "sick days." Today, most modern businesses combine everything into one single bank called Paid Time Off (PTO). You can use PTO hours to go to the beach, or you can use them when you have the flu. It is all the same time bank.
Why is my PTO accrual rate a weird decimal?
Because a year has 52 weeks, dividing numbers into standard pay periods (like 26 bi-weekly checks) almost always results in a decimal. If you are promised 80 hours a year, 80 divided by 26 is 3.0769. Payroll software uses these exact decimals to ensure that by your final paycheck of the year, your total hits exactly 80.00 hours.
