Accrued PTO: How PTO Accrual Works and Rates
What accrued PTO means, how PTO accrual works, the formulas and rates, what a good accrual rate is, and the payout liability owners miss.
Accrued PTO
What it means, how PTO accrual works, the formulas, what rate to set, and the liability most owners never calculate
Almost every guide on PTO accrual will teach you the formula and stop. Divide the hours by the pay periods, here is your number, good luck. You will get the formula here too, but it is the easy part, and it is not the part that costs you money.
The part that costs you money is that accrued PTO is not just a number in a spreadsheet. In several states it is a debt: legally earned wages you owe your employees, payable in cash, at short notice, whenever one of them leaves. Most small business owners have never computed that number for their own company, and it is usually larger than they expect.
This guide covers both. The mechanics: what accrued PTO means, how PTO accrual works, every formula with worked examples, a conversion table you can read your own rate off, and what a good accrual rate actually is. And the part nobody explains: what your accrued balance is costing you, when you have to pay it out, and how to set a rate you can afford to honor.
I built FirstHR to hold the written policy all of this depends on: stored alongside each employee profile, signed with built-in e-signature, and open to every employee through the self-service portal. This is general information rather than legal advice, and payout rules vary sharply by state.
What Is Accrued PTO?
Accrued PTO is paid time off that an employee has earned but not yet used. Rather than being handed a full year's allowance on day one, the employee builds up a balance gradually as they work, and the accrued balance is the amount they have banked and are entitled to take.
The word doing the work in that definition is earned. Accrued PTO is not a promise or an allowance. It is compensation the employee has already worked for, in the same way a paycheck is, and that is exactly why the law in several states treats it as wages rather than as a perk you can withdraw.
That framing is the difference between employers who get caught off guard and employers who do not. If you think of the balance as a number in your leave tracker, you will be surprised when someone leaves and you owe them $4,000. If you think of it as money you already owe and have not yet paid, you will plan for it.
How Does PTO Accrue?
PTO accrues by a rule you set: an amount of time earned per unit of work or per unit of the calendar. That rule is the accrual rate, and everything downstream of it (the formula, the balance, the payout) follows mechanically.
Concretely, the sequence is this. You decide the annual allowance, say 15 days. You convert it into hours, because payroll systems work in hours: 15 days at 8 hours a day is 120 hours. You pick a method: per hour worked, per pay period, or frontloaded. And you divide the 120 hours by the relevant denominator to get the rate.
Then, every pay period, the system adds that rate to the employee's balance, subtracts any time they took, and shows the result. That balance is what they can use, what appears on their pay stub, and what you may owe them in cash if they leave. Which method you pick affects your admin burden and your exposure, so it is worth choosing deliberately.
The Three Accrual Methods
There are three ways to do this, and they are not interchangeable. The right one depends on whether your staff are hourly or salaried, and on how much liability you are comfortable carrying.
The rule of thumb is simple. Hourly staff should accrue per hour worked, because the method pro-rates itself: fewer hours earn proportionally less time off, with no calculation on your part and no argument about fairness. Salaried staff should accrue per pay period, because their hours are not the unit of their work, and a fixed amount per paycheck is cleaner to explain and to budget.
Frontloading is the odd one out, because it is not really accrual. It is a grant: the simplest option and the most attractive to a new hire, with one specific risk I will come back to. You owe the full balance from day one, so in a payout state an employee who leaves in February can be owed a full year of PTO.
The PTO Accrual Formulas
Two formulas cover essentially every accrual policy in the United States. Here they are with the arithmetic worked through, because the numbers are easier to trust when you can see them.
The 2,080 figure is the standard assumption for a full-time year: 40 hours a week times 52 weeks. It is a convention rather than a law, and some employers use 2,000 for simplicity or adjust for holidays. Whichever you use, be consistent, and state it in the policy so nobody has to reverse-engineer your arithmetic.
The hourly method has one more advantage: it self-corrects for overtime, part-time, and irregular schedules without any additional logic. Someone who works more hours earns more PTO; someone who works fewer earns less. That is a feature, and it is why hourly accrual is the right default for a workforce whose hours vary.
PTO Accrual Rate Conversion Table
Rather than run the arithmetic yourself, find your annual allowance in the left column and read across. These figures assume a full-time employee working roughly 2,080 hours a year, with an 8-hour day.
| Days per year | Hours per year | Per hour worked | Biweekly (26 periods) | Semi-monthly (24) | Monthly (12) |
|---|---|---|---|---|---|
| 10 days | 80 hours | 0.0385 hrs | 3.08 hrs | 3.33 hrs | 6.67 hrs |
| 12 days | 96 hours | 0.0462 hrs | 3.69 hrs | 4.00 hrs | 8.00 hrs |
| 15 days | 120 hours | 0.0577 hrs | 4.62 hrs | 5.00 hrs | 10.00 hrs |
| 18 days | 144 hours | 0.0692 hrs | 5.54 hrs | 6.00 hrs | 12.00 hrs |
| 20 days | 160 hours | 0.0769 hrs | 6.15 hrs | 6.67 hrs | 13.33 hrs |
| 25 days | 200 hours | 0.0962 hrs | 7.69 hrs | 8.33 hrs | 16.67 hrs |
Read a row and the whole policy is there. If you want to give 15 days a year and you run biweekly payroll, your employees accrue 4.62 hours per paycheck, and after ten paychecks they have 46.2 hours, or just under six days. That is the number that will appear on the pay stub and the number they will ask you about.
A practical note on rounding: payroll systems typically carry accrual to several decimal places and round only at the point of display. Do not round the rate itself down to something tidy like 4.5 hours, because over 26 pay periods that quietly shortchanges the employee by about three hours a year, and in a payout state that is unpaid wages.
Prorated PTO for Mid-Year Hires
Prorated PTO is the share of a full annual allowance an employee earns when they work only part of the year, or only part of a full-time schedule. The arithmetic is one multiplication: the annual allowance times the fraction of the period they were actually there to earn it.
The clearest case is a frontloaded policy. If you grant 15 days (120 hours) every January and someone starts on September 1, four of the twelve months are left, so 120 times four twelfths gives 40 hours, or five days, for the rest of that year. On January 1 they move onto the full allowance with everyone else.
| Start date | Months left in the year | Share of a 120-hour allowance | In days |
|---|---|---|---|
| January 1 | 12 | 120 hours | 15.0 days |
| March 1 | 10 | 100 hours | 12.5 days |
| May 1 | 8 | 80 hours | 10.0 days |
| July 1 | 6 | 60 hours | 7.5 days |
| September 1 | 4 | 40 hours | 5.0 days |
| November 1 | 2 | 20 hours | 2.5 days |
Accrual policies prorate themselves, which is the quiet advantage over frontloading. A mid-year hire simply starts accruing on their start date and lands on the right balance without anyone computing a fraction, and the same is true when a full-time employee moves to three days a week under hourly accrual.
Two details to write down before anyone asks. First, whether you count whole months or actual days worked, because otherwise a hire who starts on the 20th becomes an argument. Second, whether a mid-year hire waits until their next anniversary to move up a tenure tier, which is what most policies do.
What Is a Good PTO Accrual Rate?
The honest answer is that it depends on what you are competing against. Still, some benchmarks are worth knowing, and the most useful ones show how much time employers actually give and how sharply that varies by employer size.
Reading those numbers practically: 10 to 15 days for a new employee is the mainstream band, and rising with tenure is the mainstream structure. Ten days is defensible and unremarkable. Fifteen is competitive. Twenty for a new hire is generous and will be noticed.
The benchmark that actually sets the right rate for you is narrower than the national average. Ask what the specific employers you lose candidates to are offering, because that is the comparison a candidate makes, and a national median tells you nothing about whether you are winning it. A small professional services firm competing with tech companies has a different problem from a small restaurant group.
Tenure Tiers
PTO allowances typically scale with length of service, and the reason is straightforward: it is a retention mechanism that costs nothing until it is earned, and it costs least for the employees most likely to leave.
The national figures show the same curve. According to the Bureau of Labor Statistics (March 2026), private industry workers average 11 paid vacation days after 1 year of service, 16 after 5 years, 18 after 10 years, and 20 after 20 years. The tiers below track that progression closely.
| Tenure | Common allowance | Biweekly accrual | Why this tier |
|---|---|---|---|
| 0 to 2 years | 10 to 12 days | 3.08 to 3.69 hrs | Competitive entry point without over-committing to someone who may not stay |
| 3 to 5 years | 15 days | 4.62 hrs | The first meaningful step up, at the point people start considering their options |
| 6 to 10 years | 18 to 20 days | 5.54 to 6.15 hrs | Rewards genuine tenure; this is where the retention effect does real work |
| 10+ years | 20 to 25 days | 6.15 to 7.69 hrs | Long-service recognition. Cheap relative to replacing someone with a decade of context |
The tiering is worth doing even at a small business, and it is worth being explicit about in the offer conversation. An employee who knows they move from 12 days to 15 at their third anniversary has a small, dated, concrete reason to still be there, and it costs you nothing until they earn it.
One design decision to make consciously: whether the step happens on the anniversary date or on January 1 following it. The anniversary is more meaningful to the employee and marginally more work to track. January 1 is simpler and slightly less motivating. Either is fine, but write down which one, because the difference is a real conversation the first time someone hits their anniversary in December.
Accrue or Frontload?
Accrue, unless you have a specific reason not to. Accrual keeps what you owe in step with the time actually earned, while frontloading puts the full year's liability on your books on day one. The two options differ in exactly one respect that matters enormously: how much you owe, and when.
The first item in the cons list is the whole argument. Frontload 15 days to a new hire on January 1, have them resign on February 15, and in a payout state you may owe them 15 days of pay for six weeks of work. Accrual would have owed them about two days. That is a real difference and it is not hypothetical.
Accrual costs you marginally more administration, and that is the whole price of it. Frontloading makes sense when turnover is low, tenure is long, and you are not in a payout state. It is a choice about risk, not about generosity, and it should be made that way.
The Liability Nobody Calculates
The balance your PTO accrual policy produces is a financial obligation you carry on your books, even though the formula-only guides never mention it. Most small business owners have never worked out what that obligation is, so here is the arithmetic.
Twenty-four thousand dollars, on a twelve-person business, that you owe and have not budgeted for. That is not a theoretical exposure. In a payout state the departing employee's balance comes due in cash on their final paycheck, and in some states within days of their last shift.
The number is worth computing for your own company, and it takes ten minutes. Total the accrued hours across your team, multiply by each person's hourly rate, and add it up. Whatever the figure is, you now know something you did not know before, and you can decide whether to manage it: with an accrual cap, by encouraging people to actually take their time, or simply by knowing what the number is when someone resigns.

Payout, Carryover, and State Law
There is no federal requirement to pay out accrued PTO. The Fair Labor Standards Act does not require payment for time not worked, including vacations and holidays, and treats such benefits as a matter of agreement between employer and employee. State law is a different matter, and this is where employers get hurt.
The statutes behind that payout list are worth reading in the original. Illinois requires an employer to pay the monetary equivalent of all earned vacation to anyone who resigns or is terminated with time left over.
Colorado goes further: its Division of Labor Standards and Statistics states that any agreement that forfeits earned compensation is void and unenforceable, so unused vacation is paid whether the employee is fired or resigns.
Four more states on that list get there through their own wage laws. Massachusetts treats vacation promised in an oral or written agreement as wages, so accrued vacation goes into the final paycheck when someone leaves. The Nebraska Wage Payment and Collection Act counts earned but unused vacation leave among the wages due at separation.
Louisiana's final pay statute bars the forfeiture of vacation pay actually earned under a company vacation policy. The North Dakota labor department states that no policy may forfeit earned paid time off at separation, with one narrow exception: a voluntary quit by someone with under a year of service who gave less than five days' notice and was told of the limit in writing at hire.
California is the strictest and best-documented example. Per the California Department of Industrial Relations, there is no requirement to provide vacation at all, but once an employer establishes a policy, accrued vacation is a form of wages that vests as it is earned.
California's Labor Code section 227.3 requires vested vacation to be paid at the final rate of pay on termination, and it bars any policy from forfeiting vested vacation. Use-it-or-lose-it is therefore prohibited there.
The other rule that trips up small businesses is jurisdictional: the law that applies is the one where the employee works, not where your company is registered. A Texas company with one remote employee in California follows California's rules for that person. With remote work, this is not an edge case anymore.
How to Calculate Vacation Pay at Separation
Vacation pay is the accrued balance in hours multiplied by the employee's rate of pay. For an hourly employee that is simply their hourly rate. For a salaried employee, divide the annual salary by 2,080: someone on $65,000 a year carrying 68 accrued hours is owed 68 times $31.25, which is $2,125.
Two things move that figure. The first is which rate applies: a policy or a state rule may require the final rate of pay rather than the rate in force when the time was earned, as California does. The second is what sits inside the balance, because sick time folded into a combined bank generally comes out payable along with the rest.
Caps and Negative Balances
Every accrual policy needs two mechanisms, a cap and a rule for negative balances, and the first is frequently confused with something illegal.
An accrual cap stops further earning once the balance reaches a set maximum. The employee stops accruing until they use some time, at which point accrual resumes, and nothing already earned is taken away. Use-it-or-lose-it is a different instrument: it forfeits time the employee has already earned.
The cap versus forfeiture distinction is legally decisive. California, Colorado, Montana, and Nebraska prohibit use-it-or-lose-it, and Montana's labor department states plainly that caps are permitted where forfeiture is not. In those states the cap is the compliant way to stop balances growing forever.
Those laws are written about vacation, but calling the bank PTO does not get you around them in California, Colorado, or Nebraska. California's labor commissioner applies the vacation rules to a combined vacation and sick leave program, while Colorado and Nebraska treat paid leave the employee may use for any purpose as vacation, whatever the policy calls it.
A reasonable cap is one and a half to two times the annual accrual: someone earning 15 days a year stops accruing somewhere between 22.5 and 30 days. That is enough headroom for a person planning a long trip and tight enough to prevent someone banking three years of PTO into a five-figure liability.
Colorado also puts a floor under the cap itself. Under its Wage Protection Rules, an employer may cap vacation only at a year's worth or more, so a 15-day policy there cannot stop accrual below 15 days.
Negative balances arise when you let someone take time they have not yet accrued, which is a kindness that requires a rule. Decide in advance whether you permit it, up to what limit, and what happens if they leave while negative.
Recovering the overpayment through a payroll deduction from the final paycheck is restricted in several states, so in practice you may simply eat it. That is fine, but decide it deliberately rather than discovering it.
Part-Time Employees and Accrual During Leave
Part-time eligibility and accrual during leave generate more disputes than any other accrual questions, and both are solved by writing the answer down before anyone asks.
Part-time employees accrue only if your policy says they do, since no federal law requires PTO for anyone. Where you do offer it, pro-rating is the norm, and hourly accrual is the cleanest way to do it.
Hourly accrual does the pro-rating for you: someone at twenty hours a week earns exactly half of what a full-timer earns, automatically, forever, with no recalculation when their hours change. If you accrue per pay period, you have to compute and maintain a separate part-time rate, and update it whenever someone's schedule shifts.
Accrual during leave is a policy choice, and you must make it explicitly. Under hourly accrual it mostly answers itself: no hours worked, no PTO earned. Under per-pay-period accrual, someone on twelve weeks of unpaid leave either continues accruing or does not, and both are defensible, but silence is not.
Most employers continue accrual during short paid absences and suspend it during extended unpaid leave. Whichever you choose, write it down, because the person coming back from leave will check their balance on their first day.
Statutory Sick Leave Accrual Is a Separate Obligation
Your PTO accrual policy is voluntary, but a state or city paid sick leave mandate is not, and the mandate does not disappear just because you have a PTO policy. This one trips up small employers constantly.
A growing number of jurisdictions require employers to provide paid sick leave that accrues at a statutory rate, commonly one hour for every thirty hours worked. That obligation is independent of whatever PTO you choose to offer. It typically covers part-time employees. It usually comes with carryover requirements and rules about what you may ask when someone uses it.
You can generally satisfy a sick leave mandate through a combined PTO bank, but only if the bank independently meets every requirement of the law: the accrual rate, the carryover rules, the permitted uses, and often a prohibition on requiring the employee to explain why they are using it. Calling the pool PTO does not make the mandate go away; the pool simply has to be good enough to contain it.
Setting Your Own Rate
Everything above, condensed into the sequence I would follow at a small business with nobody doing HR full time.
The last step is the one nobody does and it is the one I would insist on. The formula is the easy half of PTO accrual. Knowing what the resulting balance costs you, and being able to pay it on the day someone hands in their notice, is the half that separates an employer who is running a policy from one who is being run by it.
Frequently Asked Questions
What is accrued PTO?
Accrued PTO is paid time off an employee has built up through work and not yet taken. Instead of getting the whole year's allowance on the first day, the employee earns it in small increments, usually a fixed number of hours on each paycheck or a fraction of an hour for each hour on the job. Whatever has built up and not been used is their current balance, available to schedule. Several states go further and classify that balance as earned wages, so the employer cannot take it back and must pay it out in cash when the employee leaves.
How does PTO accrue?
PTO accrues under one of three methods. The first ties it to hours: each hour on the job earns a small slice of PTO, which suits hourly and part-time staff because the pro-rating happens on its own. The second ties it to payroll: every pay period adds the same fixed amount, a widely used approach and the easiest one for salaried employees. The third, frontloading, hands over the entire annual allowance in a single grant, so strictly speaking nothing accrues at all. Your choice shapes how much administration you take on and how large your liability is at any point in the year.
How do you calculate PTO accrual?
You calculate PTO accrual with one of two divisions. For accrual per hour worked, divide annual PTO hours by annual hours worked. A full-time year is roughly 2,080 hours, so an allowance of 15 days (120 hours) works out to 120 divided by 2,080, or 0.0577 hours of PTO for each hour on the job. For accrual per pay period, divide annual PTO hours by the number of paychecks in the year: 120 hours over 26 biweekly periods is 4.62 hours per paycheck. On a semi-monthly schedule (24 periods) the figure is 5.0 hours, and on a monthly schedule (12 periods) it is 10 hours.
What is a good PTO accrual rate?
A common benchmark for a new employee is 10 to 15 days a year, with more added as tenure grows. Converted to a biweekly payroll, 10 days is about 3.08 hours per paycheck, 15 days is 4.62 hours, and 20 days is 6.15 hours. Beyond that benchmark, the right number depends on your industry and on who you are hiring against. In Bureau of Labor Statistics data for March 2026, the spread is wide: 91 percent of private industry workers in management, professional, and related occupations had access to paid vacation, compared with 57 percent in service occupations. For a small business, the national average matters less than whether your rate holds up against the particular employers you lose candidates to.
What does accrued PTO mean on a pay stub?
It is the paid time off an employee has earned and not yet used, shown in hours or days. A pay stub may break this into several lines: the time accrued in the current pay period, the total accrued for the year to date, the time used, and the balance still available. The available balance is the figure that counts, because it is what the employee can actually take and the one they will ask you about. When a balance looks wrong, the usual culprits are a rate change partway through the year, an accrual cap that has paused further earning, or time off that was taken but not yet recorded.
Does accrued PTO have to be paid out when you leave?
It depends on the state where the employee works and on what your written policy says. Federal law does not require employers to pay out unused PTO. Several states, however, classify accrued vacation as earned wages owed at separation. The ones that show up consistently are California, Colorado, Illinois, Louisiana, Massachusetts, Montana, Nebraska, and North Dakota; published lists disagree about the rest because they are measuring different rules. In most other states the policy decides, and that works in both directions: a handbook that promises a payout creates an obligation you can be held to, even where the state would not have required one.
Can an employer cap PTO accrual?
In most states, yes, and a cap is not the same thing as use-it-or-lose-it. A lawful cap puts a ceiling on the balance: once an employee reaches it, they earn nothing more until they take some time off, and then accrual starts again. None of the time they have already earned disappears. The difference matters because California, Colorado, Montana, and Nebraska ban use-it-or-lose-it policies, which wipe out time already earned, while generally allowing reasonable accrual caps. In a state that bans forfeiture, the cap is the lawful tool for keeping balances from climbing without limit.
Do part-time employees accrue PTO?
Only when your policy extends PTO to them, because no federal law requires employers to offer PTO to anyone. Employers that do include part-time staff almost always pro-rate it, and the simplest way to pro-rate is to accrue per hour worked instead of per pay period. Hourly accrual scales on its own: an employee on half a full-time schedule ends up with half the PTO, and nobody has to do any math. One exception to keep in mind: a state or city paid sick leave mandate frequently covers part-time employees whatever your PTO policy says, and you cannot leave them out of it.
Does PTO accrue while you are on leave?
It depends on your written policy and on how PTO accrues under it. With hourly accrual the question mostly settles itself, because an employee who logs no hours earns no PTO. With per-pay-period accrual it is a decision you have to make and put in writing. A common approach, used by many employers, is to keep accrual running through short paid absences and pause it during long unpaid leave. Whichever rule you pick, document it: accrual during leave is one of the most common causes of balance disputes, and an ambiguous policy will be read against you.
Should a small business frontload PTO or accrue it?
Accrual is usually the safer choice for a small business. Frontloading hands over the whole year's PTO up front, which is easy to administer and appealing to new hires, but your liability for that full allowance starts on the first day. In a payout state, someone who leaves in February may be owed all of it. With accrual, the balance grows only as the time is earned, so your exposure grows in step with the time actually earned. Frontloading fits best when turnover is low, the team is long-tenured, and you are not in a payout state.
