Understanding auto parts markup from a shop
Understanding Auto Parts Markup Percentages at Auto Repair Shops
Auto repair shops often mark up the prices of parts they use in repairs to cover their overhead costs and make a profit. Understanding these markups can help consumers make informed decisions about vehicle repairs. This article explores the most common markup percentages on auto parts at repair shops and the factors influencing these rates.
Auto repair shop markup is comparable to other retail service businesses
Auto parts markup is usually 66% to 100%. That is no different than any other retail services business like plumbers, electricians, HVAC companies, or construction contractors. They all add a markup to the parts prices in addition to their labor rates. So, you’re not getting ripped off because the shop doesn’t sell parts to you at their cost.
You can buy a sump pump at a home center and install it yourself. But if you hire a contractor to install the same sump pump, they will buy it from a local supplier, mark it up by 2/3 or 100%, and bill you the marked-up price. Does that mean they’re screwing you? No. They’re a retail service, and they bill for labor and parts, just like every other retail service business
You think you’re getting screwed because you found the part cheaper online. So what?
Every day in every automotive forum, somebody claims their mechanic is ripping them off because the shop is charging more than what the part sells for online. But comparing online parts prices to the shop’s price is like comparing apples to giraffes. Here’s why it’s not a valid comparison
1) Shops don’t buy their parts online, so the price you found is irrelevant. Lots of companies sell items cheaper online, but that has no bearing on what the parts sell for at your local brick-and-mortar stores. Auto repair shops never buy their parts online. They buy parts locally from a reputable auto parts store. The shop gets a discount from the list price, but the list price is much higher at local auto parts stores than the online price you found.
Lets compare the price of an NGK 93501 spark plug for a 2015 Subaru Forrester
Here’s the price from AutoZone $11.99. Most repair shops get a 30% discount from the retail price, so their cost is $8.39 each. If they use a 100% markup, you’ll pay $16.78 each.
Here’s the price from Rockauto.com $5.93 plugs shipping
What did that prove?
It just proves that you can buy auto parts online for less than the shop pays to buy them locally. You’re not getting screwed because the shop is charging you $16.78 for a spark plug you can buy online for $5.93.
2) The shop needs to add a markup, just like every other retail service business. It’s called a profit. Businesses can’t stay in business without making a profit.
Why shops mark up the parts price
After your car has been diagnosed, here’s what happens:
• Somebody has to order the part. That labor isn’t free
• Your vehicle sits in the stall until the part arrives. Somebody has to pay for the lost productivity for that stall and that somebody is YOU.
• Somebody has to assign the part price to the invoice and pay the part suppliers at the end of the month. That labor isn’t free.
• The shop has to offer a warranty. If the part fails within the warranty period, the shop will get a free replacement, but the labor comes out of their pocket. That labor isn’t free.
• It’s a business and they make their profit on labor and parts, just like every other retail service business.
What is the average auto shop parts markup?
Up until around 2010, auto repair shops averaged about a 28% gross profit margin on parts. In the retail business, that’s considered a very low profit margin, and it’s no longer high enough for an independent shop to stay in business.
For an independent auto shop to survive, it must either raise its hourly labor rates or its parts markup or both.
Today, busy shops average a gross parts profit margin of about 45% (gross profit margin differs from markup).
If the shop buys a part for $50 and sells it for $100, they’ve doubled the cost price. They marked it up 100% but achieved a 50% gross profit margin (5% more than the minimum required to stay in business). That’s common in today’s auto repair business.
How does auto parts markup compare to other industries?
Let’s look at the profit margins of two comparable service businesses: HVAC repair/installation and electricians.
Furnace repair and installation average profit
In 2022, the typical installed price for a baseline 60,000 Btu furnace and 2-ton AC unit is around $8,900. The company’s cost for the furnace, evaporator coil, condensing unit, refrigerant, tubing, sheet metal, piping, and city permit averages about $3,300. It takes two workers about 12 man-hours to remove the old furnace and install the new setup.
• 12 hours @ $125/hr =$1,500 – actual fully loaded hourly cost of $55/hr ($660) for a labor profit of $840 (97% markup on labor).
• Salesperson’s commission @ 10%= $890
$8,900 selling price minus $3,300 parts cost = $5,600. Subtract the $890 sales commission and you get $4,710.00. Then subtract the actual cost of the labor $660.00 and the job winds up at $4,050 gross profit or a gross profit margin of 45.5%.
However, since everybody gets bent out of shape over parts markup percentage, let’s look at that by itself.
The HVAC dealer charged $8,900. The parts cost $3,300 for parts cost. When you subtract the other costs, you find that the HVAC company marked up the parts cost by almost double 97.27%.
So the dealer marked up labor by 97% and marked up the parts by 97.27%. Yet, the total gross profit margin on the total job comes out to 45.5% putting it in the ballpark of profit margins from other retail businesses.
Plumber average profit
You hire a plumber to a new 50-gallon atmospheric water heater. The going rate for a water heater installation in 2022 is around $1,800. The plumber’s cost on the water heater and supplies and permit is about $700. It takes about 1.5 hrs to install. The plumber marks up the water heater cost by 100%.
What are the normal gross profit margins for different retail businesses?
Let’s take a look at gross profit margins of different retail businesses.
Women’s clothing 46%
Furniture 44%
Optical 57%
Sporting goods 38%
Home furnishing 47%
auto parts store 37%
Tires 36%
Restaurants 61%
The average well-run auto repair shop has a gross profit margin of around 37%. That’s 37% profit margin is one of the lowest of all retail business listed above.
If you bring parts to your mechanic and you’re asking them to give away profit
Now let’s get down to the real issue. You want to save money on parts. So you buy it online and ask the shop to install it for you for just the cost of labor. In other words, you’re asking them to forfeit the profit they would have made on the part had they bought it and sold it to you at a markup. Why would they do that?
If you’re a regular customer and this is a one-time thing, they might do it as a good-will gesture. But if you’re just looking to save money at the shop’s expense, who needs a customer like you? Nobody. You’re simply trying to game the system.
Some shops won’t install customer parts
A busy shop will tell you to shove your parts where the sun doesn’t shine. And they’d be within their rights. However, if you’re a really good customer, they might make a one time exception to keep you as a customer.
Other auto repair shops increase their labor charge if you bring your own parts
A hungry shop may gladly accept your part because business is slow and they need the billing for the labor to keep the doors open. But if they’re that hungry for business, you should wonder why.
Then there are good shops that will accept customer parts, but they’ll accept the job with two caveats; First, they won’t warrant the part. Even some good parts are defective right out of the box. So if you bring parts to your mechanic and it fails fails or doesn’t fit, they won’t give you your money back and they won’t install the replacement part for free. Second, they’ll most likely charge you a higher hourly rate or a higher flat rate to compensate for the profit they lost by not selling you the part.
The truth is, you really don’t save money by providing your own parts, and you create far more problems for yourself if you bring the wrong part or the part fails.
You’re asking for trouble if you bring in an economy part
Finally, there are parts, and then there are GOOD parts. You can go online and find a part that’s much cheaper than the one the shop quoted. You think the shop is ripping you off. Nope. The part you found is most likely a Chinese made knock off, or it’s the same brand but “service grade” rather than “professional grade.” Most parts manufacturers offer two grades; an economy part for price shoppers and a professional grade for shops that value their reputation. Guess which part is junk? Do you know the difference? Because if you buy an economy part (which is what most of you penny pinchers buy) and then end up paying the shop the same price to install it, you’ll actually come out behind because the part will fail sooner.
Bottom line—every business has to make a profit
Everybody thinks the shop is ripping them off. But how many multimillionaire shop owners do YOU know? Probably none. Sure, they make a decent living. If they didn’t they’d close up shop and work for someone else. But getting rich? Nope.
So think twice about asking a shop to lose money on your next repair job because you want to bring your own parts.
