What Is a Healthy Technician Billable Utilization Rate?

A healthy technician billable utilization rate is 60 to 75 percent or higher. That is the share of paid hours your techs actually spend on billable work, after drive time, shop time, restocking, training, and slow days.

Billable Utilization = Billable Hours ÷ Total Paid Hours

A tech paid for 40 hours who bills 26 of them is at 65 percent utilization. The other 14 hours are real, you paid for them, they just did not earn revenue directly. Utilization measures how much of your labor payroll converts into billable output.

This is one of the most underrated numbers in the trades because it silently sets your labor cost. Every unbillable hour has to be paid for by the billable ones. That is why loaded labor cost divides by utilization: at 60 percent, a $35/hr tech costs about $76 per billable hour, and if utilization drops, that number climbs. Improve utilization and the cost of every billable hour falls without touching wages.

How Do You Calculate Billable Utilization Rate?

The formula above is the whole calculation, but the part owners get wrong is what goes in the denominator. Total paid hours means every hour on the clock: billable job time, drive time, shop time, training, meetings, and PTO if you pay for it. It is not "hours scheduled" and it is not "hours the tech says they worked." Pull it straight from payroll and your dispatch or field-service software so both sides of the ratio come from a system, not a guess.

The numerator is stricter than owners assume too. Billable hours are hours you can put on an invoice. A diagnostic visit that turns into a no-charge callback does not count twice, and neither does time spent waiting at a supply house because nobody pre-staged the part. If your software rounds job durations up to make techs look busier, you are measuring the wrong thing. Run the ratio weekly per tech, not just monthly for the shop as a whole, so a slump on one truck does not hide inside a decent company average.

What Is A Good Utilization Rate For Home Services?

Utilization	What it tells you
75%+	Strong: dispatching and routing are tight
60 to 74%	Healthy band for most shops
Below 60%	Labor cost is inflating; look at scheduling and drive time

Most well-run residential HVAC, plumbing, and electrical shops land in that 60 to 75 percent band. New techs, apprentices still riding with a lead, and crews in sprawling rural territories will naturally sit lower even when the shop is run well, so treat the benchmark as a range to manage toward, not a pass/fail line for every individual. A tenured tech on a tight urban route with good dispatching can push past 75 percent and stay there. What matters is the trend for each tech over time and whether the shop average is climbing or sliding.

Crew size changes the picture a little. A two-truck outfit feels every scheduling gap immediately because there is no third truck to absorb slack, while a ten-truck shop can average out a bad day on one route against a good day on another. That is exactly why per-tech tracking matters more as you grow: the average can look fine while two trucks are quietly bleeding hours.

Why Does Low Utilization Drive Up Labor Cost?

Because unbillable hours still get paid, and that cost has to be recovered from billable hours. Fewer billable hours means each one carries more cost, which is why loaded labor cost divides by utilization. A worked example makes it concrete: take a shop running four techs at $35/hr loaded, each paid for 40 hours a week. At 65 percent utilization, that crew bills roughly 104 hours a week combined; at 55 percent, the same payroll only produces about 88 billable hours. Same cost, fewer hours to spread it across, so the effective cost per billable hour rises on every job those techs touch, whether or not you ever change a wage.

This is also why utilization and pricing are connected even though they look like separate problems. If your markup targets assume a certain labor cost per hour and utilization quietly drifts down, your margin erodes on jobs priced correctly six months ago. Utilization and labor cost are two sides of one coin, so read this with What Is Loaded Labor Cost?. To see how utilization flows into what a job actually costs, run the Job-Costing Calculator, and use the Margin Leak Check to spot where paid hours are disappearing.

Where Does Utilization Leak?

None of these show up as a line item on a P&L, which is exactly why they go unmanaged for years:

• Routing — inefficient dispatching that sends the closest truck to the wrong job piles on drive time across the whole day.
• Scheduling gaps — loose booking that leaves 45 minutes of dead air between appointments, multiplied across every tech, every day.
• Parts and material waits — techs standing at a counter or sitting in a driveway because nobody pre-staged what the job needed.
• Admin creep — paperwork, photos, and follow-up calls that could be handled by an office role instead of a technician's paid hour.
• Callbacks and rework — a job that has to be redone eats a second block of paid time against the same original invoice. If this is a recurring drain, Acceptable Callback and Rework Rate is the companion metric to check next.

Fixing routing and scheduling is usually the fastest lever, because it does not require hiring or training, just tighter dispatch discipline and a look at how appointment windows get booked.

Common Mistakes That Hide A Utilization Problem

The most common mistake is treating a busy-looking crew as a productive one. A tech can be paid full-time and still sit at 50 percent utilization if half the day is windshield time and shop runs. A truck that leaves at 7am and returns at 5pm looks like a full day of work; it says nothing about how many of those hours were billable. Track the ratio, not the appearance of busyness.

A second, quieter mistake is averaging utilization across the whole shop and calling it done. A company average of 68 percent can be hiding one tech at 80 percent and another at 50 percent. The 50 percent tech is the one actually setting your labor cost problem, and a shop-wide number will never surface them. This is also where utilization connects to a broader dashboarding habit: it belongs alongside the other numbers owners should be watching weekly, covered in Five KPIs HVAC Owners Should Track, and it is worth putting on the agenda of your Weekly Operating Meeting rather than reviewing it only at month-end when the slow week is already sunk cost.

A third mistake is chasing utilization in isolation. Pushing a tech's billable hours up by overbooking the schedule can spike the ratio while tanking callback rates and rushing installs, which costs more in rework than utilization ever saved. The goal is a sustainable ratio, not a maximum one.

How To Improve Technician Utilization

Improving utilization rarely means working techs harder. It usually means removing the friction between jobs:

1. Tighten routing. Cluster appointments geographically instead of dispatching in call order. Less drive time per job is pure utilization gain with zero added labor cost.
2. Pre-stage parts. A truck stocked for the day's known jobs, and a warehouse pull ready before a tech arrives, eliminates supply-house detours.
3. Move admin off the truck. Photos, invoicing, and follow-up calls handled by dispatch or an office coordinator free technician hours for billable work.
4. Buffer the schedule realistically. A calendar booked back-to-back with zero slack looks efficient on paper but collapses the first time a job runs long, creating cascading gaps for the rest of the day.
5. Coach the outliers, not the average. Once you have per-tech numbers, a 15-minute conversation with the two techs dragging the average down moves the shop number more than a shop-wide policy change.

Because utilization sets your effective labor cost, a shop that lifts its average from 55 to 65 percent is not just "more efficient," it is functionally giving itself a raise on every job without touching a paycheck. That is also why it shows up as a lever in Revenue Per Technician: the same billable hour, priced the same way, produces more revenue per tech when fewer paid hours are wasted getting to it.

This benchmark comes from the Home Services Metrics Scorecard, the KPI catalog the M1COS dashboards run on. For general, non-industry-specific guidance on managing payroll costs and cash flow as a small business, the SBA and SCORE both publish free resources, and the Bureau of Labor Statistics tracks broader labor-cost and employment trends if you want context beyond the trades.

Frequently Asked Questions

What counts as a billable hour?

Time a technician spends on work you can charge a customer for. Drive time, shop time, training, and waiting on parts are paid but not billable, and they pull utilization down. If a visit does not result in an invoiceable line, it is not billable, no matter how necessary it was.

Why does low utilization raise my labor cost?

Because unbillable hours still get paid, and that cost has to be recovered from billable hours. Fewer billable hours means each one carries more cost, which is why loaded labor cost divides by utilization.

Is 75 percent utilization realistic?

Yes, with tight dispatching and routing. Most well-run shops live in the 60 to 75 percent band. Consistently above 75 percent is strong; below 60 percent signals scheduling or drive-time problems worth digging into before they show up as a margin problem.

Should utilization targets be the same for every technician?

No. A new hire or apprentice riding with a lead will run lower utilization than a tenured tech on a tight route, and that is expected. Track each tech's trend over time against the 60 to 75 percent band rather than holding every truck to an identical number regardless of tenure or territory.

How often should I review utilization?

Weekly, per technician, not just monthly at the shop level. A monthly shop-wide average can hide one truck sliding toward 50 percent behind another truck running above 75 percent. Weekly per-tech review is what actually catches the drift while it is still cheap to fix.
