How do I calculate my shop's effective labor rate?
Short answer
Total labor dollars collected divided by total hours actually worked by techs. If it's below your posted door rate by more than 20 percent, you're bleeding time somewhere.
Door rate is not what you're actually collecting
Your posted rate is what you charge on the book. Your effective labor rate is what you actually collect divided by hours your techs clocked or booked. Discounts, comebacks, warranty work, and flat-rate jobs that ran long all drag it down.
Run it monthly, not once a year
Pull total labor revenue for the month and total tech hours for the month, including comebacks and warranty time that generated zero labor dollars. Divide. That's your real number, and it's the one that pays your bills.
If your effective rate is 20 to 30 percent below your posted rate, look at how many jobs are quoted flat rate but taking hourly time, how many comebacks you're eating, and how much shop time is unbilled cleanup and moving cars.
Use it to price and to manage techs
This number tells you the truth about both your pricing and your shop floor. A tech who books high flat-rate hours but whose actual jobs run long everywhere is either undertrained or fudging the clock.
Compare effective rate by tech, not just shop-wide. It tells you who to put on the harder diagnostic work and who needs more oversight on quoting.
Effective labor rate worked example
| Posted door rate | $130/hr |
|---|---|
| Total labor revenue this month | $41,600 |
| Total tech hours clocked (all jobs) | 400 hrs |
| Effective labor rate$41,600 / 400 hrs | $104/hr |
| Gap vs door rate | 20% below |
The math: Effective labor rate = total labor dollars collected for the period divided by total tech hours worked in that same period, including unbilled and warranty time.
Where the gap usually hides
- 1.Comeback hours that generated zero new labor revenue
- 2.Warranty labor paid at a discounted rate by the parts supplier
- 3.Flat-rate jobs quoted low that ran two or three hours over
- 4.Techs clocked in but not on a billed job (cleanup, parts runs, training)
- 5.Discounts given at the counter that never get tracked against the job
Where owners get this wrong
- Only tracking door rate and assuming that's what you're collecting.
- Not separating comeback and warranty hours from billed hours in your reporting.
