Vacation time is accrued under whatever system your employer has written into its policy: usually a fixed amount added each pay period, an amount tied to hours actually worked, or a lump sum granted at the start of the year or on your work anniversary. No federal law requires paid vacation, so the accrual rate, the waiting period before it starts, and the rules about carrying hours forward all come from your employment agreement or company handbook.1U.S. Department of Labor.

The Three Accrual Methods Employers Use
Most policies fall into one of three patterns. Which one applies to you determines how quickly your balance grows and when you can start spending it.
Per Pay Period
You earn a fixed number of hours with each paycheck. If your policy grants two weeks (80 hours) a year and payroll runs 26 biweekly cycles, that’s about 3.08 hours per period (80 ÷ 26). The balance climbs steadily across the year, and once hours appear on your pay stub you can generally use them, subject to any waiting rule the employer sets.
Per Hour Worked
Some employers add vacation to your balance based on hours you actually clock. A common figure is roughly 0.0385 vacation hours for every hour worked, which produces about 80 vacation hours over a standard 2,080-hour year. Retail, hospitality, and healthcare employers lean on this method because schedules swing week to week; workers who put in more hours accrue more vacation, and light weeks produce less.
Front-Loaded (Lump Sum)
Instead of building the balance, the employer deposits the full annual allotment at once, on January 1, the fiscal year start, or your hire anniversary. If you’re entitled to 80 hours, all 80 land in your account on day one of the cycle. It’s the simplest system to administer, but it exposes the employer if you leave shortly after the grant, because some state laws require paying out the full unused balance.
When Accrual Actually Starts
The date on your offer letter is not always the date the clock starts.
Waiting Periods
Many employers impose a 30-, 60-, or 90-day introductory window before new hires begin accruing. In some policies you accrue no hours at all during that stretch; in others you accrue but cannot use the time until the period ends. If you leave during a waiting period, you generally aren’t owed a payout, because nothing has vested.
Full-Time Versus Part-Time
Full-time employees usually get the full rate. Part-timers often accrue proportionally — a half-time worker at half the full-time rate, for example. Temporary and contract workers are commonly excluded from vacation programs altogether, since their pay is structured around a defined project or hourly rate.
How Rates Grow With Tenure
Accrual rates tend to step up as you stay longer. Bureau of Labor Statistics figures for civilian workers show these rough averages:
- After 1 year of service: 11 days per year
- After 5 years: 15 days per year
- After 10 years: 18 days per year
- After 20 years: 20 days per year
Your employer’s schedule may look different.2Bureau of Labor Statistics. Paid Sick Leave, Paid Vacation, and Consolidated Leave Plan Provisions in the United States, December 2022 The tiers and the anniversary at which each one activates are set in the handbook; most policies require you to reach the milestone before the higher rate turns on.
Caps and Carryover
Most employers set a ceiling on how many hours you can bank at once. Once you hit the cap, accrual pauses until you use some of the balance. A typical cap sits at 1.5 to 2 times the annual allotment, so an 80-hour-a-year policy might cap at 120 or 160.
Carryover works alongside the cap. Some policies let unused hours roll into the new year indefinitely (up to the cap). Others use “use-it-or-lose-it,” wiping unused time at year end. Whether that wipe is legal depends on your state. Even where it’s permitted, employers generally must give you a reasonable chance to use the hours before they expire.
State Rules That Decide Whether Your Hours Are Safe
Because no federal statute governs vacation, state law fills the gap, and it varies sharply. The key question in each state is whether accrued vacation counts as earned wages.
Roughly nine states require employers to pay out all earned, unused vacation whenever an employee leaves, for any reason. In those states, accrued vacation is treated the same as unpaid wages, and a handbook clause forfeiting it will not hold. Most other states let the employer’s written policy decide. If the handbook says unused vacation is forfeited at separation, that language is generally enforceable where no state payout mandate exists.
Use-it-or-lose-it splits along similar lines. A small number of states forbid employers from erasing accrued vacation at year end. Most allow the practice if the deadline is communicated and workers have a reasonable chance to use the time. Some states permit use-it-or-lose-it during employment but still require payout of any accrued balance at termination, meaning the employer can force a December 31 deadline while you’re on the payroll but cannot pocket the hours if you resign in November.
The cleanest way to know where you stand is to check your state labor agency’s guidance alongside your handbook.
What Happens to the Balance When You Leave
At resignation, layoff, or termination, payout depends on the same two variables: state law and the written policy. In states that treat accrued vacation as wages, the employer must include the value of your remaining hours in your final paycheck, and failing to do so exposes the employer to the same penalties as withholding regular pay. In states without a payout mandate, the policy controls; if it says no payout, you may receive nothing.
Unlimited PTO Doesn’t Accrue the Same Way
Unlimited paid time off replaces accrual with a policy that lets you take as much approved leave as you want. Because nothing formally lands in a balance, there’s usually nothing to pay out at separation.
That’s clean on paper but messier in practice. In states that treat accrued vacation as wages, regulators sometimes look at the shape of an “unlimited” policy and find a measurable entitlement inside it — minimum usage expectations, extra approval hurdles past a certain point, or an annual cap on days taken. Where that happens, the capped or expected figure can become the presumptive amount owed at separation. A policy limiting usage to six weeks a year, for instance, may be treated as a six-week entitlement.
If your employer is switching you from traditional accrual to unlimited PTO, watch what happens to the balance you already built. Paying it out before the switch is best practice, and a legal requirement in some states. An employer that simply zeroes out the balance may be exposed to a wage claim depending on where you work.
Checking Your Own Accrual
Because the written terms carry more weight than anything a manager tells you in passing, it’s worth confirming a few things directly.
- Read the offer letter and handbook for the accrual method, waiting period, cap, carryover rule, and separation payout policy. If anything is missing, ask for it in writing.
- Compare the balance on your pay stub against the accrual rate in the handbook. The math should match, pay period after pay period.
- Look up your state’s rules on payout at termination and use-it-or-lose-it. The state labor department’s site is the most reliable source.
- If your employer shorts you on a payout that state law requires, file a wage claim with your state labor agency. Many states set a two-year deadline for these claims.
