How to tell if a repair quote is fair

Step 1: split the quote into three lines

Every repair quote is parts, labor and fees added together. If yours is one number, ask the shop to list the three lines. A shop that cannot or will not do that is a reason to get another quote.

Our example job is a front brake pad replacement. Its typical US range is $190 to $400: parts of $60 to $130, 1.2 to 1.6 hours of labor, and small fees. See the example box above, then check your own number on the quote checker.

Step 2: compare the hourly labor rate

Labor is the part of a quote that changes most from city to city. The table below the steps shows the shop rate we use for 10 big metro areas, and the state table under it shows all 50 states and DC. We take the average pay for auto technicians from the US Bureau of Labor Statistics (May 2025) and multiply it by 4.0 to 5.5, because a shop's posted rate also pays for the building, tools, insurance and profit. The multiplier is our assumption, so a single shop can sit outside it.

The lowest rate range in the 10 big areas is $105 to $145 an hour (Houston and Dallas). The highest is $125 to $175 an hour (Boston). Dealers usually charge more than independent shops. If your rate is well above the top of the range for your area, ask why. See why shop labor rates differ by city.

Step 3: ask how the labor hours were set

Most shops bill flat-rate hours, also called book hours. A labor guide lists a standard time for each job on each car, and the shop bills that time no matter how long the work really takes. If the technician is fast, you still pay book time. If the job runs long, you still pay book time. That is normal.

What you can check is whether the hours are close to the usual hours for the job. Our ranges use 1.2 to 1.6 hours for a front brake pad job, 1.3 to 2.5 hours for an alternator and 0.3 to 0.8 hours for a battery. If a quote shows far more hours than that, ask which labor guide the shop used and how many hours it lists. Also ask whether two jobs that share steps, like a water pump and a timing belt, are billed with the overlap taken out.

Step 4: look at the parts line

A shop buys a part at a trade price and sells it to you for more. That markup pays for finding the part, handling returns and standing behind a warranty. Shops set it differently and we do not have a measured number for it, so we do not give a percentage. What you can compare is the part price against the parts range for the job: for front brake pads our range is $60 to $130, for a battery $120 to $320, and for an alternator $220 to $520.

Ask whether the part is new, rebuilt or used, and whether it is OEM (from the car maker) or aftermarket. A catalytic converter shows how much that choice matters: our aftermarket and dealer part bands put the total at $430 to $1,525 and $1,025 to $2,325. See catalytic converter replacement cost.

Step 5: ask about fees and the diagnostic charge

Fees are shop supplies, disposal of old parts and fluids, and diagnosis. In our ranges the fee line tops out at $25 for front brake pads, $25 for a battery and $30 for an alternator. A much larger unexplained fee is worth a question.

A diagnosis is the time the shop spends finding the cause. Our diagnostic scan range is $55 to $250 for 0.5 to 1.5 hours of work. Ask what the diagnosis covers and whether the fee is taken off the repair if you go ahead. Many auto parts stores read a check-engine code for free, so you can know the code before you talk to a shop. Our check-engine code pages show what each code can cost.

Questions to ask the shop

1. Can you list the parts, the labor hours, the hourly rate and the fees on separate lines?

2. Is the part new, rebuilt or used, and is it OEM or aftermarket?

3. How many hours is the labor, and which labor guide is that from?

4. What does the diagnostic fee cover, and does it come off the repair?

5. What is the warranty on the parts and on the labor?

6. What happens if you find something else once the car is apart? Will you call me before doing extra work?

7. Can I see the old part, or the reading that shows it failed?

Red flags

A single lump-sum price with no breakdown.

Pressure to decide now, or a warning that the price is only good today.

Work started before you approved a price. Many states require written authorization before repairs; check the rule where you live.

Labor hours far above the usual hours for the job, or two charges for the same labor.

A fee with a vague name and a large amount, such as "shop charges".

A shop that will not show you the old part or the reading that shows the repair is needed.

When to get a second quote

Get a second written quote for the same job when any of these is true.

Your price is above the top of the typical range. Our checker calls a price "a bit high" up to 20 percent over the top of the range and "way high" beyond that.

The quote is a lump sum and the shop will not itemize it.

The repair is a large one. For a front brake pad job the fair zone is about $230 to $330, but on a repair like a catalytic converter ($430 to $2,325) the range is wide and one more quote costs little compared with the difference.

The shop wants to replace a part to see if it fixes the problem, and has not tested the part first. A code like P0420 can come from a sensor or an exhaust leak, not only the converter, so ask what test points to the part.

Put the same questions to the second shop and compare the three lines, not only the total. Then run both numbers through the quote checker.
