Unlimited PTO: How Many Days Do People Actually Take?

The Benefit That Often Gives You Less

"Unlimited PTO" is one of the most marketed perks in modern employment. It signals trust, flexibility, and a culture that values output over hours. The phrase is so reflexively positive that it has become a default selling point in tech and startup recruiting decks.

It also tends to result in employees taking less vacation, not more.

That sentence is the most consistent finding across the small but growing body of research on unlimited PTO outcomes. When the cap goes away, the implicit norms that emerge in its place are often more restrictive than the policies they replaced. Workers without a defined number to anchor against tend to take fewer days, defer trips longer, and worry more about how their leave usage looks. The numbers that have been publicly reported back this up consistently -- though the published data is patchier than most articles on the topic admit.

This piece walks through what we actually know, what's been reported by transparent companies, and how to think about whether unlimited is a benefit or a costume. For the full picture of what unused leave costs you, our hidden cost of unused PTO breakdown puts dollar figures on the days you don't take.

What Does the Research Actually Show?

The most-cited figure in the unlimited PTO debate is the gap between unlimited and traditional PTO holders in average days taken per year. Research from HR analytics firm Namely, published in their 2017 workforce report and referenced widely since, found that employees on unlimited PTO took roughly 13 days per year on average, compared to 15 days for employees with traditional defined-allotment policies.

The two-day gap is small in absolute terms but the direction surprised most observers. The whole pitch of unlimited PTO assumes employees will take more days when the ceiling is removed. The actual outcome -- measurably fewer days -- points to something else going on.

Subsequent reporting from organizations including the Harvard Business Review, MIT Sloan Management Review, and the Society for Human Resource Management has reinforced the same general finding: unlimited PTO programs, on average, do not increase vacation usage and frequently reduce it. The reasons proposed are consistent across the analyses:

• Loss of psychological ownership. A defined allotment is "yours." You earned it. You can spend it. An unlimited bank is a discretionary request, not a deposit.
• Norm anxiety. Without a stated baseline, employees calibrate to what they observe peers and managers doing. In high-performance cultures, the observed norm is usually low.
• Manager discretion creep. Even when policy is unlimited, managers retain approval authority. Employees who don't want to be the test case for "how much is too much" stay conservative.
• No payout incentive. Defined PTO turns into a year-end forfeiture risk that nudges usage. Unlimited PTO has no balance and no forfeiture, removing the use-it-or-lose-it pressure that historically prompted late-year trips.

The research is not unanimous. Some employers report that unlimited policies, paired with explicit minimums or manager-driven encouragement, do increase usage. The pattern across published cases: unlimited policies can work, but only when the company actively pushes against the natural tendency toward under-use.

What Have Specific Companies Reported?

A handful of companies publish data on what their unlimited PTO programs actually produce. These are the most useful data points because they cut through the marketing.

Two patterns stand out. First, companies that publish average days taken under unlimited policies consistently report figures clustered around 13–14 days -- meaningfully below the 17–20 days commonly seen in countries with statutory leave entitlements, and below the average defined-PTO worker in the US.

Second, the companies that get higher usage out of unlimited policies all do something explicit to push against under-use. Buffer publishes employee vacation data internally. Help Scout requires a minimum number of weeks. FullContact has at points paid employees a bonus to actually take their time off. Without one of these mechanisms, the default outcome is below-average usage.

The numbers should also be read with one caveat: most companies don't publish averages at all. The data we have skews toward transparency-oriented firms whose cultures may actively support more leave-taking than the median unlimited-PTO employer. The true average across all unlimited PTO programs is plausibly lower than the publicly reported figures suggest.

Why Do Workers Take Less Under Unlimited PTO?

Behavioral economists and organizational psychologists have proposed several mechanisms for why a removed cap reduces usage. The dominant ones:

Endowment effect inversion. A defined PTO bank is something you own. Endowment effect research shows people place higher value on what they already possess. Unlimited PTO inverts this -- you don't own a balance, you request time. The ask carries a small psychological cost that the take-from-balance action does not.

Ambiguity aversion. When the rules are ambiguous, risk-averse decision-makers under-use the right. "How much can I take?" becomes a guessing game where the guess is calibrated to avoid being the outlier on the high side.

Social-proof anchoring. Employees calibrate behavior to what they observe. In an organization where senior managers visibly take 8 days a year, taking 20 feels conspicuous. Defined PTO creates an explicit anchor (the number on your balance) that overrides the observation-based anchor; unlimited removes the explicit anchor entirely.

Loss of forfeiture pressure. Defined PTO with year-end use-it-or-lose-it creates a calendar-driven push to take days in November and December. Unlimited PTO has no such forcing function.

Perceived signaling cost. In high-performance cultures, the perceived signal of taking a lot of time off is "low commitment." Defined PTO normalizes a specific number (whatever the policy is). Unlimited puts the burden of normalization on each individual employee.

The interaction of these mechanisms is well-documented in HR research and consistent with what employees actually report when surveyed about their unlimited-PTO experience. The most common phrase in employee feedback: "I just don't know how much is okay to take."

What About the Employer Side?

Unlimited PTO is also attractive to employers for reasons that don't always make it into the recruiting deck.

No accrual liability on the balance sheet. Defined PTO is a wage liability that grows over time and must be paid out at separation in many states (see PTO payout when you quit: state rules for the state-by-state breakdown). Unlimited PTO has no accrued balance, so there's nothing to pay out. For a company with hundreds of employees, this can eliminate millions in liability that traditional PTO would have carried.

No payout cost at termination. Related to the above. When employees leave defined-PTO roles, employers cut a lump-sum check. With unlimited, there's no balance to settle. The savings go to the employer.

Reduced bookkeeping. No need to track balances, accruals, caps, or carryover. The administrative cost of unlimited PTO is genuinely lower.

Recruiting signal. Even with the muted usage data, "unlimited PTO" remains a strong recruiting signal, particularly for younger workers and those evaluating culture-forward employers.

None of these are inherently bad. They explain why unlimited PTO has spread so quickly without much consideration of whether it produces more leave-taking. The headline benefit (no balance liability) accrues to the employer. The headline cost (lower usage) accrues to the employee. The two parties have asymmetric incentives, which is why the policy is so durable even as the usage data accumulates against it.

When Does Unlimited PTO Actually Work?

Unlimited PTO programs that produce good employee outcomes share a few features:

1. Explicit minimum. Companies that require a minimum number of weeks taken per year (Help Scout's policy is a well-known example) get higher usage than those that don't. The minimum acts as the anchor that the policy otherwise removed.

2. Manager-modeled usage. When senior leaders visibly take meaningful time off and broadcast it, the social-proof effect runs in the right direction. When they don't, employees calibrate down.

3. Leadership PTO transparency. Some companies publish vacation data for leadership and managers. The transparency keeps the modeling honest.

4. Bonus to take time off. A small number of companies have experimented with paying employees a bonus contingent on taking a vacation. The structures vary; the principle is to offset the perceived signaling cost of leave-taking with a concrete reward.

5. Holiday closures. Mandatory company-wide closures (between Christmas and New Year, for example, or a "summer week off") force usage that wouldn't happen under purely individual choice.

If your unlimited PTO employer has none of these features, the policy is more accurately described as "discretionary PTO" -- and the published averages suggest you'll end up taking fewer days than you would on a traditional 15- or 20-day plan.

How Should You Think About Your Own Usage?

If you're under unlimited PTO, the practical decision framework:

Set your own anchor. Don't ask "how much is okay" -- ask "how much would I be entitled to under the standard plan I was offered before this one?" That number is roughly 15–20 days for most professional roles. Take that.

Plan in advance, not reactively. Unlimited PTO encourages reactive use ("I need a long weekend, let me take Friday off"). The data on well-being and burnout is clearest for blocks of time off -- week-long trips, multi-day disconnects. Reactive long weekends, while better than nothing, don't deliver the same restorative value as planned vacations. Our piece on how holiday bridges work covers how to maximize the calendar with strategic planning.

Talk to your manager up front. The single most useful conversation you can have on day one of an unlimited-PTO job is to ask your manager directly what they consider a reasonable amount of leave usage. If their answer is meaningfully below 15 days, that tells you something about the culture and may inform whether you stay or move.

Track your usage. Unlimited PTO removes the system-level tracking, which makes it easy to drift. Keep your own count. At year-end, compare against the 15–20 day baseline you would have had.

Ask about minimum policies. If your employer doesn't have a minimum, ask if they'd consider implementing one. Some companies have responded to internal pressure by adding minimums after the fact.

If you're evaluating an unlimited-PTO job offer, treat the policy as roughly equivalent to a 13-day defined plan when running compensation comparisons. That's the median outcome based on the published data. If the company has explicit usage minimums and visible leadership modeling, mark it up. If they don't, don't pay a premium for the "unlimited" label.

What This Means for Your Career

Unlimited PTO is neither uniformly good nor uniformly bad. It works well at a small number of companies that have built explicit countervailing structures. It produces below-average usage almost everywhere else. The average outcome -- 13 days per year, less than peers on traditional plans -- is the data point worth remembering.

The deeper takeaway: vacation policy structure shapes vacation behavior, often in ways that are opposite to what the policy name suggests. "Unlimited" means "discretionary" in practice, and discretionary almost always means "less" without active intervention. If you care about actually taking your time off, you need either a defined plan with a clear number, or an unlimited plan at one of the small minority of employers that genuinely supports usage.
