What you walk away with

Outcome
Efficiency, productivity and proficiency for one technician, and the dollar value of a single point of efficiency.
Time
About 6 minutes

Technician efficiency is billed hours divided by clocked hours. Productivity is clocked hours divided by available hours. Those are different measurements of different failures, and quoting one while meaning the other is how shops end up arguing past each other in a pay-plan meeting. The calculator returns both, plus what a point is worth in dollars.

Key takeaways

  • Efficiency is billed over clocked. It says how the work went once it started.
  • Productivity is clocked over available. It says how much of the day reached a job.
  • Proficiency is the two multiplied, and it is the one that tracks shop sales.
  • A point of efficiency is worth clocked hours times 1% times your effective rate.

hrs

hrs

Time punched onto jobs.

hrs

Hours the technician was scheduled to be here.

$/hr

What a billed hour is worth to you after discounts and comebacks.

The arithmetic

Efficiency
172 billed ÷ 164 clocked = 104.9%
Productivity
164 clocked ÷ 184 available = 89.1%
Proficiency
172 billed ÷ 184 available = 93.5%
Value of a point
164 × 0.01 × $161.00 = $264.04

Efficiency and productivity measure different failures. A technician at 110% efficiency and 60% productivity is quick on the job and sitting for half the day, which is a dispatch problem. Reverse the two numbers and it is a training or a labor-time problem. Multiply them and you get proficiency, which is the only one that tracks what the shop sold.

What counts as a billed hour?

What the labor line said the job was worth. On most tickets that comes from book time or from a canned job the shop wrote itself, so the billed hour is a published or agreed figure rather than a stopwatch reading.

It gets fixed in advance because a customer has to approve a price before anybody starts. California requires a shop to hand over "a written estimated price for labor and parts necessary for a specific job" and bars charging above it without consent. Once the customer says yes, the hours on that line stop moving, and every minute after that lands in the clocked column.

Clocked hours are what the technician punched onto jobs. Available hours are what they were scheduled to be at the shop. Keeping those two separate is most of the work here, because a shop that treats them as one number loses the ability to tell a dispatch problem from a training problem.

Some clocked time could never have been flagged at all. The federal regulation covering the dealership overtime exemption defines a mechanic as "any employee primarily engaged in doing mechanical work" and names "washing, cleaning, painting, polishing, tire changing" as work that sits outside it. That exemption is a dealership rule and an independent shop should take its own advice on it. The line is still the right one for a time clock. An hour spent moving cars around the lot is not an hour anybody could have billed.

Why do the three numbers disagree?

Because each divides by something different, and the denominators tell you where the loss is.

MeasureFormulaWhat a low number means
EfficiencyBilled ÷ clockedThe work took longer than it sold for
ProductivityClocked ÷ availableThe technician was there and not on a job
ProficiencyBilled ÷ availableEither of the above, or both

Take the two failures apart. A technician at 110% efficiency and 54% productivity is quick on every job and sitting for half the day, which is a dispatch and workflow problem that no amount of training will touch. Reverse it, at 73% efficiency and 98% productivity, and you have somebody on a job all day who cannot make the times. The answer there is training, better tooling or a labor guide time that is wrong for the work.

A month for one technician, worked through

The calculator loads with 172 billed hours, 164 clocked hours and 184 available hours, at an effective labor rate of $161.

Efficiency is 172 over 164, or 104.9%. Productivity is 164 over 184, or 89.1%. Proficiency is 172 over 184, which is 93.5%, and it equals the first two multiplied together. Labor sold is 172 hours at $161, which is $27,692 for the month from one technician.

Twenty hours of the scheduled month never reached a job. At this technician's efficiency those twenty hours would have flagged 20.98 billed hours, which is $3,377 of labor at the same effective rate. That is what the productivity gap cost, from one technician, in one month.

What is a point of efficiency worth?

Clocked hours multiplied by one percent, multiplied by the effective rate. Here that is 164 × 0.01 × $161, which is $264.04 a month.

Use your effective labor rate in that calculation rather than the door rate. A point of efficiency produces billed hours, and billed hours are worth what your shop keeps per hour after discounting, not what the sign says.

Why does efficiency pass 100%?

Because the two hours in the formula are measured by different instruments. A billed hour is a published or agreed figure that was fixed before the work started. A clocked hour is a punch clock. Finish a two-hour job in ninety minutes and the ticket still bills two, so the ratio goes over one. On flat rate pay that gap is the whole arrangement.

Payroll still runs on the clock side of it. Federal wage rules reach a technician "paid a flat sum for a day's work or for doing a particular job, without regard to the number of hours worked", and they set the regular rate by "totaling all the sums received at such day rates or job rates in the workweek" and then dividing by every hour the technician worked. Overtime comes off that figure. So a flat-rate shop is already collecting clocked hours for a reason that has nothing to do with this calculation, which means the denominator is sitting in payroll waiting for you.

A figure far above 100% on one job family deserves a second look though. It can mean the technician is quick on that work. The other reading is that the time being sold for that job is generous, which shows up later as a customer comparing your invoice with somebody else's. The comparison of book time and actual time covers where the gap is ordinary and where it is a signal.

What do you do with a low number?

Read which denominator moved. Low productivity is a scheduling or a bay problem and it belongs to the shop. Low efficiency belongs to training and tooling, and to the accuracy of the times being sold.

Then price it. Multiply the gap in points by the dollar figure the calculator returns, and the conversation stops being about attitude. Definitions sit in technician efficiency and technician productivity, the hours these numbers feed are in the break-even calculator, and the rest is on the tools hub.

Questions shops ask

What is the technician efficiency formula?
Billed hours divided by clocked hours. Billed hours are what the labor lines said the work was worth, and clocked hours are the time punched onto those jobs. A technician who flags 8 hours in a 7 hour stretch of clock time is running at 114%.
How is productivity different from efficiency?
Productivity is clocked hours divided by available hours, so it measures how much of the scheduled day reached a job at all. Efficiency measures how the work went once it started. A technician can be excellent at one and poor at the other, and the two failures need opposite fixes.
Can efficiency be over 100%?
Yes. A billed hour is a published or agreed labor time fixed before the work started, and a clocked hour is a punch clock, so a technician who finishes a 2 hour job in 90 minutes still bills 2 and the ratio goes over one. On flat rate pay that gap is the point of the whole arrangement. A figure far above 100% on one job type is worth a look, because it can also mean the labor time being sold for that job is generous.
What is proficiency?
Billed hours divided by available hours, which is efficiency multiplied by productivity. It is the only one of the three that tracks what the shop sold, because it counts the hours the technician was scheduled to be there rather than the hours they happened to punch onto a ticket.
What does one point of efficiency earn?
Clocked hours multiplied by one percent, multiplied by your effective labor rate. Over 164 clocked hours at a $161 effective rate, a single point is $264 a month for one technician. Across four technicians and a year, that is real money and it explains why pay plans are argued about.
Should efficiency drive a pay plan on its own?
No, because a technician does not control dispatch. Paying on efficiency alone rewards somebody who cherry-picks familiar work and punishes the one who takes the electrical diagnosis nobody wants. Put proficiency next to it, since proficiency counts the hours the shop scheduled, and keep the comeback rate in the same conversation.
