How to Calculate PTO Liability for Your Company

PTO liability formula: unused days times daily rate times employees equals $76,923 on the balance sheet

Key takeaways

PTO liability is the value of time off your team has earned but not taken yet. It's what you'd owe if everyone cashed out today.
The formula: unused PTO days × daily rate × number of employees, where the daily rate is annual salary ÷ working days per year.
A carryover cap limits how much rolls into next year, but it doesn't lower what you owe today, and some states don't let you wipe earned days.
Averages give you an estimate. Your real liability comes from each person's actual balance and pay rate.

There's a number on your balance sheet that people tend to forget about: the time off your team has already earned but hasn't taken yet. That's your PTO liability, and it's a real debt. If everyone cashed out their balance tomorrow, you'd have to pay it.

Here's how to calculate it, with a simple formula and a 50-person example from our free PTO liability calculator. I covered all of this in a video, so go ahead and watch it first:

What Is PTO Liability?

PTO liability is the dollar value of paid time off your employees have earned but not yet used. It's what you'd owe if everyone cashed out their balance today, and under US GAAP (ASC 710) it goes on your balance sheet as a liability. It grows a little every workday, as people earn more time off.

"If everybody cashed out tomorrow, as unlikely as that is, you would still have to pay it."

You'll also see it called accrued PTO liability or accrued vacation liability. Our glossary has the full definition of leave liability.

The PTO Liability Formula

PTO liability = unused PTO days per employee × daily rate × number of employees
Daily rate = annual salary ÷ working days per year

For hourly teams, use unused hours × hourly rate instead.

The calculator works with team-wide averages, which is the fastest way to get a ballpark. The precise version takes each person's balance times their own rate, added up. That's the number accountants actually book.

Worked Example: PTO Liability for a 50-Person Company

PTO liability calculator filled in for 50 employees, $100,000 average salary, 20 PTO days and 4 unused days

Here's the example from the video: a 50-person company with an average salary of $100,000. Everyone gets 20 days of PTO a year, and on average people end the year with 4 days unused.

The calculator divides salary by 260 working days by default (52 weeks × 5 weekdays). Paid holidays aren't subtracted, because they're still paid days. If your team works a different schedule, use your own number.

PTO liability calculator results showing $76,923 total liability and $1,538 per employee

Output	Value
Daily rate	$384.62
Total PTO liability	$76,923
Liability per employee	$1,538
Annual cost of the PTO benefit	$384,615

How it's calculated:

Daily rate: $100,000 ÷ 260
Total PTO liability: 4 × 50 = 200 unused days × $384.62
Liability per employee: $76,923 ÷ 50
Annual cost of the PTO benefit: 20 × 50 × $384.62

"The reason that there's 76,000 left over at the end is because on average people are leaving 4 days on the table."

How a Carryover Cap Changes Your PTO Liability

A 2-day carryover cap keeps $38,462 of PTO liability from rolling into next year

Add a carryover cap of 2 days to the same example. People leave 4 days on the table, but only 2 can roll into next year. That's $38,462 a year that stops carrying forward.

"It's a good lever to play with because it can protect your downside."

The cap doesn't lower what you owe today, though. It limits what carries into next year. And in states that treat earned vacation as wages, like California and Colorado, you can't wipe out days people already earned. There, use an accrual cap instead, so people stop earning once they hit the limit. Our guide to PTO payout laws by state has the details.

What the Calculator Leaves Out

Real balances. It's an estimate based on averages, not each person's balance and pay rate.
Sick leave. Separate sick leave usually doesn't count, but a combined PTO bank does.
Location rules. Payout rules differ by state and country. Check yours on our leave laws pages.
Payroll taxes and benefits. Add them if your accountant includes them.

This post is general information, not legal or accounting advice.

Use-It-or-Lose-It vs. Unlimited PTO

If you want to change the number structurally, you have two levers.

Use-it-or-lose-it clears unused balances at year end, where it's legal. The liability still builds during the year, though, and it's banned in California, Colorado and some other states.

Unlimited PTO mostly removes the liability, because nothing accrues. The trade-off is culture:

"The main trade-off… is that people will either abuse it and take too much time off, or you'll start to have a company culture where people take less time off."

If you switch, honor existing balances first, and put the policy in writing. More in our unlimited PTO policy guide.

How to Track Your Real PTO Liability

"Doing this all in a spreadsheet would kind of suck."

Vacation Tracker keeps every employee's real balances by leave type and location. To get to the liability, export the leave balance report and multiply each balance by that person's pay rate. Or connect Claude, ChatGPT or Copilot through our MCP integration and ask it to do the math for you.

Frequently asked questions

Is accrued PTO a liability?

Yes. Under US GAAP (ASC 710), accrued PTO is recorded as a liability when four conditions are met: the time off was earned by past work, it vests or carries over, payment is probable, and the amount can be estimated. Most accrual-based vacation policies meet all four, so the unused balance belongs on your balance sheet.

Is accrued PTO a current liability?

Usually, yes. Accrued PTO is normally listed under current liabilities (often inside accrued liabilities or accrued payroll) because employees are expected to use it, or be paid for it, within the next 12 months. If a large share of balances won't be used for years, part of it may be long-term. Confirm the split with your accountant.

How do you record PTO liability in your books?

As employees earn PTO, you debit PTO (or vacation) expense and credit accrued PTO liability. When someone takes the time off or gets paid out, you debit the liability and credit cash or wages payable. Many teams true up the balance once a month, so the liability on the books matches the real balances at each close.

How do you calculate PTO liability for salaried and hourly employees?

For salaried employees, divide annual salary by working days per year (260 is the usual default) to get a daily rate, then multiply by unused days. For hourly employees, multiply unused hours by the hourly rate. If you want an hourly figure for salaried staff, divide salary by 2,080 hours (260 days × 8 hours).

Should PTO liability include employer payroll taxes?

Many finance teams include them, because you'll owe the employer share of payroll taxes when the time off is paid. In the US, that's 7.65% for Social Security and Medicare, plus any state taxes. Our PTO liability calculator leaves taxes and benefits out, so add them on top if your accountant books them.

Do employers have to pay out accrued PTO when someone leaves?

There's no federal requirement. The Fair Labor Standards Act doesn't require pay for time not worked. Some states, such as California and Colorado, treat earned vacation as wages that must be paid out at the final rate of pay. Check the rules for each state you employ people in with our PTO payout laws by state and the PTO payout calculator.

Does sick leave count toward PTO liability?

Generally not when it's a separate bucket that isn't paid out. ASC 710 doesn't require you to accrue non-vesting sick pay. A combined PTO bank is different: it usually counts in full, and in California a combined bank is treated as vacation and must be paid out.

Does unlimited PTO eliminate PTO liability?

Mostly, because nothing accrues. But you usually have to honor or pay out existing balances when you switch, and in California a vague or unwritten "unlimited" policy can still create payout obligations. A real unlimited policy needs to be in writing and clearly communicated.

How often should you recalculate PTO liability?

Monthly, or at each financial close. Balances change every pay period as people earn and use time off, and salaries change with raises. Recalculating at each close keeps the number on your balance sheet close to what you'd actually owe.
