PTO stands for paid time off. It is time away from work that your employer still pays you for, pulled from a set number of hours or days you get each year.
Most companies use one PTO balance to cover several kinds of leave. You take a day off, your balance drops by a day, and your paycheck stays the same. Whether that day was a holiday trip or a bad cold usually does not matter.
Two other things share the abbreviation, so it is worth a quick check that you are in the right place. On a tractor or truck, PTO means power take-off, the shaft that sends engine power to attached equipment. At a school, PTO usually means Parent Teacher Organization. This guide is only about the workplace kind.
What PTO covers
A PTO balance normally pays for:
- Vacation. A trip, a long weekend, or a day at home doing nothing.
- Sick days. A cold, a stomach bug, or a day you are no use to anyone.
- Personal days. A school play, a house move, a car that needs the garage.
- Appointments. A dentist visit that only runs during working hours.
- Mental health days. Increasingly treated the same as a physical sick day.
Some kinds of leave usually sit outside the PTO balance and get their own rules:
- Public holidays. Often paid separately, so taking 4 July off does not cost you a PTO day. Some employers give floating holidays instead, so you can swap in a holiday your own family actually keeps.
- Parental leave. Time off for a new baby, usually its own policy with its own length and its own pay rate.
- Bereavement leave. A few days after a death in the family, normally granted on top of PTO rather than out of it.
- Jury duty. Employers cannot punish you for serving, and many pay for the days without touching your balance.
- Long medical leave. Extended illness or surgery, often covered by the Family and Medical Leave Act or short-term disability rather than by PTO.
- Volunteer time off. A day or two a year for community work, at companies that offer it.
Ask your employer which bucket each one comes from. Two companies can both say "20 days of PTO" and mean quite different things.
How PTO works
There are three common ways to hand it out.
You earn it as you go
This is accrual. You collect a small amount of PTO for every pay period or every hour you work. Work half a year, and you have about half a year's worth to spend. New hires often start at zero and build up from there.
You get the whole year at once
Your full balance lands on 1 January, or on your work anniversary. You can book a two-week trip in February if you want to. The risk is leaving in March after spending time you had not really earned yet, and some employers will claw that back.
Unlimited PTO
There is no balance. You ask, your manager approves, you go. It sounds like the best deal of the three and often is not, for two reasons. People tend to take fewer days when no number tells them what is fair, because nobody wants to be the one who took too much. And because you never accrue a balance, there is nothing to pay out when you leave.
PTO vs vacation: what is the difference
Vacation is one reason to take a day off. PTO is the pot of paid days you take it from.
The practical difference shows up when you are sick. Under an older split system, you had separate vacation days and sick days, and a cold only ate into the sick pile. Under one PTO balance, a week of flu and a week in Portugal cost you exactly the same thing. That is simpler to run and it gives you more freedom, but it does mean a rough winter can eat the trip you were saving for.
How much PTO is normal in the US
There is no single right number, but the US Bureau of Labor Statistics tracks it. Private-sector workers average roughly 11 paid vacation days after one year of service, near 15 days after five years, and around 20 days after twenty years. Those figures are vacation only, so a combined PTO balance that also has to cover sick days is usually larger.
Against that, 20 days of PTO for a new hire is a strong offer. Ten is on the low side for a salaried role. And "days" is doing a lot of work in those numbers, which brings us to the maths.
What 40 hours of PTO actually means
Employers often quote PTO in hours, which makes it hard to picture. Convert it by dividing by the length of your working day.
- 40 hours of PTO, on 8-hour days, is 5 days off
- 80 hours is 10 days, or two working weeks
- 120 hours is 15 days, or three working weeks
Watch out on a 10-hour shift. The same 40 hours buys you only 4 days.
Accrual can be worked out the same way. Say a job offers 15 days a year on 8-hour days. That is 120 hours. Paid every two weeks, across 26 pay periods, you earn about 4.6 hours of PTO each payday. Measured per hour worked, across a 2,080-hour year, it comes to roughly 3 and a half minutes of paid leave for every hour you put in. Our PTO accrual calculator does this for any policy, including part-time hours.
PTO for part-time and hourly workers
Salaried staff usually get a flat number of days. Hourly and part-time staff are more often paid PTO per hour worked, which keeps it proportional. Work half the hours, earn half the PTO.
A common rate is one hour of PTO for every 30 or 40 hours worked, which is also the shape many state sick-leave laws use. At one hour per 30, a 20-hour week earns about 0.67 hours of PTO a week, so roughly 35 hours across a year. The catch to watch for is a slow month: if your hours drop, so does what you accrue that month.
Two other things to check if you are part-time. Some employers set a minimum weekly hours threshold before you qualify for PTO at all. And a PTO day for an hourly worker is normally paid at your base rate for your scheduled hours, so a day off during a week you would have worked overtime does not pay the overtime rate.
How to ask for PTO
Most companies want three things: notice, a request in writing, and a manager's approval before you book anything.
Notice periods vary. Two weeks for a single day and a month or more for a longer trip is common, and sickness is the obvious exception since nobody plans it. Put in the request through whatever system your employer uses rather than mentioning it in passing, because a verbal yes leaves no record when payroll asks later.
A manager can turn a request down. That surprises people, but PTO is a benefit rather than a guaranteed right to a specific date, and the usual reasons are a staffing clash or a deadline. A good policy says how far ahead you must ask, who decides when two people want the same week, and whether any weeks are blocked off. If yours does not say, ask before you book the flights.
Is PTO required by law?
No federal law makes a US employer offer paid vacation or paid PTO. The Fair Labor Standards Act sets rules for minimum wage and overtime, and stays quiet on paid leave. It is a benefit companies choose to offer to attract people.
State and city law is a different story, and it moves fast. A growing list of states requires employers to provide paid sick leave, with its own accrual rate and its own rules about carrying it over. If your PTO policy has to cover sick time, it has to meet whatever your state requires as a floor. Check your state rather than assuming, because this is the part of PTO that changes most often.
What happens to unused PTO
Three things can happen at the end of the year, and your policy will say which:
- Carry over. Unused days roll into next year, often up to a cap.
- Use it or lose it. The balance resets and unused days disappear. Some states ban this for earned vacation.
- Payout. The company pays you for unused days in cash.
Carry-over usually comes with a cap, and there are two different caps worth knowing apart. A carry-over cap limits how much you can roll into next year, say 40 hours. An accrual cap limits your total balance at any moment, so once you hit the ceiling you stop earning until you take some time off. The second one catches people out: you can be quietly earning nothing for months without noticing.
When you leave a job, it depends on where you work. A few states, California among them, treat earned vacation as wages you have already worked for, so it has to be paid out in your final cheque. Elsewhere it comes down to company policy, and plenty of policies pay nothing. This is also the hidden cost of unlimited PTO: with no balance, there is nothing to pay out.
What to check in your own policy
Six questions worth asking, whether you are joining a company or writing the policy:
- Is it accrued, granted in a lump sum, or unlimited?
- Does sick time come out of the same balance as vacation?
- What is the accrual rate, and is there a cap on the total balance?
- How much unused time can I carry into next year?
- How much notice do I need to give, and who approves it?
- What happens to my balance if I leave?
Get those six in writing. Almost every PTO argument at work traces back to one of them being vague.
How to track PTO
Small teams start in a spreadsheet, and it works right up until it does not. The usual failure is not the maths, it is that there is only one copy of the truth and it lives on somebody's laptop. Two people book the same week. An accrual gets missed for a month. Somebody asks how many days they have left and nobody can answer without opening a file.
What you actually need is:
- One place where people request time off
- A manager who gets the request and can approve it
- A balance each person can check themselves, without asking
- Booked leave visible next to the work being planned, so you do not promise a deadline in a week when half the team is away
TimeTracker does this alongside the hours your team already logs. You set real leave policies with accrual rules and opening balances, people request time off and managers approve it, and everyone can see their own balance. Approved leave shows on the team schedule, so you can see who is actually available before you commit to a date. You can export timecards, leave and balances to CSV when payroll needs them. Worth saying plainly: that export is a CSV file, not a direct connection to a payroll provider.
