PTO is easier to plan when you know where your working hours go. If you work on a computer, Voltti tracks your real minutes in every app on Mac and Windows, with no timer to start or stop, and gives you daily and weekly reports. Focus sessions call you back with a banner when you drift, so the days before a break count. With Voltti Teams, a team lead sees who is working now and pays for real hours.

How it works

How PTO accrual is calculated.

  1. Turn your yearly PTO into hours. Multiply days by the hours in your workday. 15 days at 8 hours is 120 hours.
  2. Divide by your paychecks in a year. Weekly is 52, biweekly is 26, semi-monthly is 24 and monthly is 12. 120 hours / 26 = about 4.62 hours per paycheck.
  3. Count the paychecks until your date. About 3 months from now is 6 biweekly paychecks, so you earn 6 x 4.615 = 27.69 hours.
  4. Add it to what you have. Start with your balance, add what you earn, take off the time you plan to use, and stop at your cap if you have one.

Example: you get 15 days a year, you're paid biweekly and you have 24 hours saved. In about 3 months you'll have 24 + 27.69 = 51.69 hours, or about 6.46 days.

If you earn PTO by hours worked, the math is per hour. At 1 hour for every 30 hours worked, a 40 hour week earns 40 / 30 = 1.33 hours, which is about 69 hours a year. This kind of rule is common for paid sick leave. For a single span of time, the business days calculator counts the workdays your time off covers.

PTO policies vary by employer and by state, including how time is earned, whether there is a cap and what happens to unused time. Check your handbook or HR team for your real numbers. This calculator gives an estimate, not legal or payroll advice.

FAQ

PTO accrual, answered.

How do I calculate PTO accrual per pay period?

Turn your yearly PTO into hours, then divide by the number of paychecks you get in a year. 80 hours a year paid biweekly is 80 / 26 = 3.08 hours per paycheck. Enter your numbers above and the calculator does it for you.

What does accruing PTO mean?

It means you earn paid time off bit by bit as you work, instead of getting it all at once. Each paycheck, or each hour you work, adds a little to your balance.

How does 1 hour for every 30 hours worked add up?

Divide your hours worked by 30. At 40 hours a week that is 1.33 hours a week, or about 69 hours over 52 weeks. Part-time hours earn less, since the rate follows the hours you work.

What is a PTO cap?

Some employers set a most you can hold at once. When your balance reaches it, you stop earning until you use some time. Enter your cap above and the calculator stops adding PTO there and shows what you would miss.

How are pay periods counted until my date?

The calculator counts full pay periods from today: every 7 days for weekly, every 14 days for biweekly, every whole month for monthly and every half month for semi-monthly. By hours worked, it counts full weeks. Your real pay dates may shift the total by one paycheck.

Is my data saved anywhere?

Your numbers stay in your browser so they're still there when you come back. Nothing is sent to a server.

Can I track my working hours automatically?

If you work on a computer, yes. Voltti for Mac and Voltti for Windows record every real minute in your apps and work websites, with no timer to start or stop. If you only need to add up hours by hand, try the work hours calculator.
