Understanding comp time: How it works and calculation

Comp time

Compensatory time, or comp time, is a benefit businesses sometimes offer to employees for working overtime. In the United States, it is heavily regulated by the Department of Labor, so it’s vital that team members and employers understand what it is and how it works.

Comp time can promote work-life balance and effectively manage labor costs, but it’s not the right solution for everyone. This article will explain comp time, how it works, and the legal requirements employers must follow.

What is comp time?

Comp time offers paid time off in lieu of overtime pay. If an employee works more than their standard hours per week, the company will credit them with PTO instead of paying them an overtime rate.

Employers should maintain a detailed roster of how many overtime hours a team member works to ensure that they compensate employees fairly.

Comp time vs. overtime pay

To understand how comp time works, it helps to distinguish it from overtime pay. Here are a few differences: 

  • Compensation structure: Comp time off is given instead of time and a half pay for working extra hours.
  • Compensation type: Employees earning hourly wages are typically nonexempt under the FLSA and must be paid overtime for extra hours worked. Conversely, exempt salary workers may earn comp time—if their company offers it.
  • Legal requirements and limitations: Comp time is typically reserved for public-sector employees and exempt private-sector team members. The accrual limit is usually 240 hours per year.

Is comp time a legal requirement?

Strict compensatory time off guidelines govern who is eligible for this form of compensation. 

Typically, it’s reserved for specific public sector employees—police officers, emergency medical technicians, and firefighters. These jobs often require overtime, and it’s only fair that workers are compensated for it.

However, there are strict criteria governing how employees earn comp time, such as:

  • Union negotiation: Employers must arrange an agreement with union reps, if applicable.
  • Employee agreement before granting comp time: The team member must agree to the comp time arrangement before working overtime. 
  • Time and a half accrual: If a public sector employee works more than 40 hours per week, comp time must be paid at time and a half, just like overtime.
  • Maximum accrual limits: The Fair Labor Standards Act (FLSA) states that public sector employees can accrue up to 240 hours of compensatory time yearly. However, workers in public safety, emergency response, and seasonal roles may accumulate up to 480 hours per year.
  • The timeframe for using comp time: FLSA nonexempt employees must use their comp time by the end of the 26th pay cycle after the pay period in which it was earned. Specific government employees may be entitled to a payout of unused time.

Does that mean private-sector employees aren’t entitled to comp time? Not necessarily. Employees exempt from the FLSA can earn comp time since they’re not entitled to overtime pay anyway.

Exempt employees include any worker who isn’t legally required to earn additional compensation for working overtime—most often, those earning a salary. Comp time for salaried employees can provide motivation for them to work overtime despite this. Ultimately, the company decides whether to offer comp time for exempt employees.

It’s generally illegal for employers to offer nonexempt employees comp time instead of overtime. The FLSA mandates that nonexempt workers be paid extra for overtime (hours beyond 40 for most full-time workers).

How to calculate comp time

Calculating comp time is straightforward, but employers must do so carefully to ensure compliance with employment contracts and labor laws.

First, calculate how many overtime hours your employee worked. Record extra hours in a roster as they’re accumulated to ensure accurate accounting. If the employee worked more than 40 hours in a week, you must give them a time-and-a-half rate. That means giving 15 hours of comp time for 10 hours of overtime.

Which is better: Comp time or overtime pay? 

Some people would rather get time off than earn extra money for the additional hours they put in. Whether comp time or overtime is better depends largely on the employee’s opinion and whether they’re exempt or nonexempt under the FLSA. 

Nonexempt employees don’t have a choice, as overtime law requires they be paid overtime, even if they prefer comp time.

Exempt employees who aren’t entitled to overtime pay will likely be more amenable to comp time. This added benefit may increase motivation by rewarding hard-working employees.

FAQ’s

Is “comp time” the same thing as “compensatory time”?

Yes—most people use “comp time” as shorthand for “compensatory time.” The important part isn’t the label, it’s the rule set you’re operating under. In the US, comp time can mean very different things depending on whether you’re talking about public-sector employees, federal employees following OPM guidance, or private-sector employees who are exempt from overtime rules. If your policy doesn’t clearly state who’s eligible and which framework applies, you’re basically inviting a wage-and-hour dispute.

What’s the difference between comp time and flex time?

Flex time is a scheduling arrangement—you’re changing when someone works, usually within the same workweek or pay period. Comp time is compensation—you’re paying someone back for extra hours with paid time off instead of cash (where it’s allowed). That difference matters because flex time can still trigger overtime if a nonexempt employee’s total hours go past 40 in a workweek, while comp time is heavily restricted and, in the private sector, generally can’t replace overtime pay for nonexempt employees. In practice: flex time is an operations tool, and comp time is a compensation promise.

Can salaried employees get comp time without creating legal risk?

Sometimes, but you need to be disciplined about the “why” and the documentation. For exempt employees, comp time is typically a discretionary benefit rather than a wage replacement, so you can offer it as recognition for unusual peaks in workload. The risk shows up when comp time starts looking like you’re tracking exempt employees like hourly workers, docking pay when they don’t “make up” hours, or using comp time to paper over a role that should actually be nonexempt. If you’re offering comp time to salaried employees, write the policy to make it clear it’s not tied to hours worked minute-by-minute, it’s manager-approved, and it doesn’t change exempt status.

How does comp time work for federal employees (OPM comp time) compared to FLSA comp time?

Federal comp time is its own world. OPM guidance allows compensatory time off in lieu of overtime pay for eligible federal employees under specific conditions, and the rules can differ based on whether someone is FLSA-exempt or FLSA-nonexempt and what type of overtime work is being performed. The big takeaway is that “OPM comp time” isn’t a template private employers can copy-paste. If you’re not a federal agency, treat OPM rules as informative context—not a compliance shortcut.

What should a comp time policy include to avoid disputes later?

You’re trying to prevent two predictable problems: employees feeling shortchanged and Finance discovering an untracked liability. A solid policy spells out eligibility (by classification and location), approval rules (who can authorize extra time and when), how accrual is recorded, when comp time must be used, what happens at separation, and how you handle blackouts or business-critical periods. It should also explain how comp time interacts with other time-off types like PTO, sick leave, and company holidays, so managers aren’t improvising country-by-country or team-by-team.
