How to Calculate Your Shop's Effective Labor Rate

Effective labor rate is what you actually collected for an hour of billed labor. Your door rate is what you meant to collect. The gap between them is where discounts, write-offs, and unbilled diagnosis hide.

This page is the formula and a worked example. The numbers come from your tickets. GreaseGoose does not ship a separate effective-labor-rate report today. Every labor line on a GreaseGoose repair order carries hours and rate, so the inputs are already in one place. For setting the door rate itself, use the labor rate calculator.

The formula

Effective labor rate = labor sales ÷ billed hours

Use the same period for both numbers: a week, a month, or a quarter. Count labor only. Parts, shop supplies, and tax stay out.

• Labor sales: the labor dollars you invoiced in that period, after discounts that hit labor.
• Billed hours: the labor hours you put on those invoices.

If you billed $18,000 of labor on 150 hours, the effective labor rate is $18,000 ÷ 150 = $120.

Worked example

Sample Auto Repair posts a $140 door rate. Last month the shop invoiced $18,000 of labor on 150 billed hours.

• Effective labor rate = $18,000 ÷ 150 = $120 / hour
• Door rate = $140 / hour
• Realization = $120 ÷ $140 = 85.7%

The shop wrote 150 hours on invoices and collected $120 per hour, not $140. The missing $20 per hour is $3,000 for the month.

Billed hours vs clock hours

Billed hours are what went on the ticket. Clock hours are what the tech was on the clock. Effective labor rate uses billed hours. If you divide labor sales by clock hours you are measuring something else: how much labor you collected per hour you paid for.

A tech can be productive on the clock and still show a low effective rate if the advisor discounted the line or did not bill the diagnosis.

Why ELR is lower than your door rate

Common leaks:

• Discounts on the labor line to "make the number work"
• Write-offs after a comeback or a complaint
• Menu pricing that does not match book time at your door rate
• Unbilled diagnosis that ate an hour you never put on the invoice
• Comebacks you ate to keep a customer

None of those are automatically wrong. They just have to be visible, or the door rate on the wall is a wish.

5 ways to raise it

1. Charge for diagnosis. Put diagnostic time on the estimate and get it approved. See how to set a diagnostic fee.
2. Bill book time. If the book says 1.8 hours, bill 1.8 unless you have a reason not to.
3. Cut casual discounts. A $20 courtesy on labor is a habit that shows up in this formula.
4. Read labor lines by tech and advisor. The hours and rates are on each repair order. Look for who is writing off time.
5. Review declined work. Yellow items that never come back are hours you already spent inspecting. Win back customers who declined work.

FAQ

What is the effective labor rate formula?

Effective labor rate is labor sales divided by billed hours for the same period. Use labor dollars only, after labor discounts, and the hours you put on those invoices.

Why is effective labor rate lower than door rate?

Discounts, write-offs, comebacks, menu prices that do not match book time, and diagnosis you never billed all pull the number down. The door rate is the list price. Effective labor rate is what you collected.

Should I use billed hours or clock hours?

Use billed hours for effective labor rate. Clock hours answer a different question: labor collected per hour you paid a tech.
