Idle Time: Definition, How to Measure It, and Reducing the Cost
Idle time is paid working time during which an employee is available but not producing, whether measured as minutes without keyboard or mouse activity in a time-tracking tool or as scheduled hours that had no work to fill them, and it is compensable under the FLSA when the employee is engaged to wait.
Idle time is time an employee is on the clock but not producing work. The term is used in two different ways that managers should keep apart. In time-tracking software, idle time means a stretch of minutes with no keyboard, mouse, or app activity on the tracked device. In labor cost accounting and workforce management, idle time means scheduled, paid hours that had no work to fill them, such as an agent sitting in available status with an empty queue. Both are paid time. Neither is the same thing as slacking.
What Is Idle Time?
Start with the legal fact, because it shapes everything else. The DOL's Fact Sheet #22 distinguishes an employee who is "engaged to wait," which is paid, from one who is "waiting to be engaged," which is not. Its example is a secretary who reads a book while waiting for dictation. She is working, because the employer controls her time and she cannot use the wait for her own purposes. An agent staring at an empty queue is in the same position. Idle time inside a shift is therefore compensable, and no productivity metric changes that.
What idle time does change is cost efficiency. A center that schedules 50 agents for a Tuesday afternoon that only needs 38 will pay for 12 agents' worth of idle hours. The employer's lever is scheduling and workload design, not the paycheck.
The software definition
Time-tracking tools flag idle time when no input is detected for a set threshold, commonly somewhere between three and ten minutes. The employee is then prompted to keep or discard the idle stretch. This definition catches two very different things: someone who walked away from the desk, and someone who was thinking, reading a printed document, or on a phone call that the software cannot see. Treating every idle flag as non-work produces false accusations. Treating none of them as signal wastes the data. The right use is as a prompt for a conversation, and as a trend line rather than a daily verdict.
The workforce management definition
Contact centers rarely use the phrase "idle time" on wallboards. They talk about available time, which is the paid time an agent is ready for contacts but has none, and it shows up as low occupancy rate. In project-based teams, idle time is bench time: billable staff between assignments. In both cases the time is real labor cost with no revenue against it.
Measuring Idle Time
The basic ratio is:
Idle time percentage = Idle minutes ÷ Total tracked minutes × 100
For contact centers, the equivalent is 100 minus occupancy, since occupancy is the share of logged-in time spent handling contacts or in after-call work.
A worked example
A 40-person remote back-office team for an insurance BPO tracks time on HiveDesk. Over a week, each employee logs 40 hours, or 2,400 minutes, and the average idle time flagged by the desktop app is 264 minutes, or 11 percent. At a fully loaded cost of $24.00 an hour, that idle share is worth:
- Idle hours per employee per week: 264 ÷ 60 = 4.4 hours
- Cost per employee per week: 4.4 × $24.00 = $105.60
- Cost across 40 employees per week: $4,224.00
- Annualized over 52 weeks: $219,648.00
When the team lead looked at the pattern instead of the total, most of the idle minutes clustered between 8:00 and 8:30 a.m., before the client's overnight batch of claims arrived. Starting the shift 30 minutes later, with no reduction in hours, cut idle time to 6 percent. The saving came from realigning the schedule with the work, not from pressuring employees.
Idle Time vs Related Measures
| Idle time | Unproductive time | Shrinkage | |
|---|---|---|---|
| What it measures | Paid minutes with no activity or no work available | Paid minutes on non-work activity (personal browsing) | Paid time not available for scheduled work (breaks, training, absence) |
| Cause | Workload gaps, waiting, thinking, offline tasks | Employee choice | Planned and unplanned absence from the queue |
| Who controls it | Mostly the employer, through scheduling | Mostly the employee | Both |
| Fix | Better forecasting and shift alignment | Coaching and clear expectations | Accurate shrinkage assumptions in the staffing model |
The distinction matters for fairness. An agent with high idle time during a slow week has done nothing wrong. An agent with high unproductive time has. Lumping the two together in a single "productivity score" leads to disputes and, in a unionized environment, grievances.
Idle Time in Contact Centers and Remote Teams
A 120-seat outsourced retail support center staffs to a forecast built on last year's volume. In the two weeks after a client's product recall, volume runs 40 percent above forecast and idle time disappears. Occupancy hits 94 percent, agents skip after-call notes to take the next contact, and attrition risk rises. Then volume drops to 15 percent below forecast for a month, and occupancy falls to 68 percent. Agents are now idle a third of the time. The center's problem is not agent behavior in either period. It is a forecast that could not react. The fix the center adopted was intraday flexing: offering voluntary time off during low-volume hours and cross-training agents to handle a second client's chat queue when their own queue emptied.
For remote knowledge workers the idle signal is less useful as a cost measure and more useful as a wellbeing and workload signal. A developer whose idle time drops to near zero for three weeks may be heading for burnout, and a designer with rising idle time may be blocked on approvals. Managers get more out of asking why than out of reacting to the number.
How to Track Idle Time
HiveDesk's desktop app records active time and flags periods with no keyboard or mouse activity, so idle minutes appear on the timesheet as a separate figure rather than being silently counted as work. Employees see the same data as their manager, which keeps the conversation factual. Periodic screenshots give context for what was on screen before and after an idle stretch, useful for distinguishing a phone call from an absence. Task and project tracking lets employees tag time to specific work, so a block of idle minutes between tasks shows up as a gap in the schedule rather than a fault in the person. Reports break idle time down by employee, day, and hour, which is how the insurance team in the example above found its 8:00 a.m. cluster. The plan is $5/user/month, with a 14-day free trial, and includes the desktop, mobile, and browser apps.
Set the idle threshold deliberately
A three-minute threshold on a phone-heavy team generates noise, because every call looks idle to the keyboard. Teams that do most of their work by voice usually set a longer threshold or exclude call time, and teams that work entirely in a browser can use a shorter one.
See Where the Idle Minutes Cluster
HiveDesk separates active time from idle time on every timesheet and reports it by hour and by employee, so schedules can be realigned with the work. $5/user/month, 14-day free trial.

Frequently Asked Questions
Is idle time paid? Yes, when the employee is on duty and cannot use the time for their own purposes. The FLSA treats an employee who is engaged to wait as working. Employers reduce the cost of idle time through scheduling, not by withholding pay.
What is a normal idle time percentage? It depends on the work. Voice-heavy roles show high software idle time because calls do not generate keystrokes. Back-office and development roles on well-designed workloads often land in the single digits or low teens. Track the trend for each role rather than comparing across roles.
Does idle time in a time tracker mean the employee was not working? No. It means no keyboard or mouse input was detected. Phone calls, reading, meetings, and thinking all look idle to the software. Use screenshots and a conversation to interpret it.
What is the difference between idle time and shrinkage? Shrinkage is time agents are paid but not available for the queue, such as breaks, training, and absence. Idle time is time they are available but have no work. A center can have low shrinkage and high idle time at the same time if it is overstaffed.
How do you reduce idle time without cutting hours? Align shift starts with when work actually arrives, cross-train staff to absorb a second queue or task type, offer voluntary time off in predictable troughs, and fix upstream blockers that leave people waiting for approvals or inputs.
