This car repair calculator estimates what a repair should cost before you call a garage. Pick one of 20 common jobs, from front brake pads to a remanufactured transmission, then your vehicle type, state and where you plan to take it. The result is a low, typical and high price, split into parts and labor, built from the $132 national hourly rate at an independent shop.
Add what the car would sell for, and the tool also shows the bill as a share of its value. A next-step line names the detailed page for options this quick version skips, such as rear brakes or R-1234yf refrigerant.
Car Repair Cost Calculator
Pick the job, your vehicle type, state and kind of shop. You get a low, typical and high price, the split between parts and labor, and the detailed page to open next for that job.
Your Estimate
Estimates only, not a quote. Labor uses the $132 national average posted rate (Tekmetric, June 2026) scaled by state technician pay (BLS, May 2025) and by shop type; collision jobs use the $85 national body rate (NABR, August 2026). Parts bands are shop list prices for a midsize sedan, already including the usual parts markup. Sales tax is not included.
What a Car Repair Calculator Adds Up, and What It Leaves Out
A repair estimate is a written forecast of parts, labor and charges for one job, made before work starts. This one stacks four lines: parts at retail (what the garage charges, not what it pays), labor at your state’s posted rate, flat items such as refrigerant by the pound, and supplies at 5 percent of labor, capped at $35. The book-time math has its own page, the auto repair labor calculator.
Left out on purpose: a diagnostic fee (every job here is already identified; budget $132 at an independent, $165 at a dealer), sales tax, which varies by state, and routine maintenance costs.
The Four Choices That Move the Price
The job sets the base. These inputs shift it without touching the hardware:
| Input | What it scales | Range used |
|---|---|---|
| State | Labor rate | $103 (West Virginia) to $159 (Washington, DC) |
| Dealer or dealership | Labor and parts | +25 percent on each |
| Chain or mobile mechanic | Labor (chains also parts) | Chain 0.95 labor, 1.05 parts; mobile 0.85 labor |
| Vehicle class | Parts only | Compact 0.90 to luxury 1.60; hybrid or electric 1.40 |
The $132 base is Tekmetric’s June 2026 average across more than 10,000 shops, adjusted by state automotive technician pay from the BLS May 2025 wage survey (method on the auto repair labor rates page). The dealer labor gap follows AAA; the other multipliers are planning estimates. Collision rows use the $85 NABR body rate for August 2026 plus $48 per paint hour.

Why Car Repair Calculator Results for One Symptom Look So Different
Check the share column. A head gasket is 70 percent labor, about 15.1 book hours, while a used engine costs more yet takes fewer hours because the block arrives ready to bolt in. Two honest quotes for one overheating car can sit thousands apart. Wear items like pads track driving habits and come back every few years; the costly repairs near the bottom have new and used part options on their detailed pages.
One Brake Job, Two Prices: A California Dealer Example
Take the $480 baseline pad and rotor job and change three inputs: a crossover, a dealer, California’s $153 rate. Parts become $290.50 x 1.10 x 1.25 = $399.44. Labor is 1.38 hours x $191.25 = $263.93, plus $13.20 in supplies. Typical total: $675 (range $610 to $745), about $195 more for identical hardware.
When a Repair Is Not Worth Paying For
A repair under half the vehicle’s value is usually worth doing if nothing else big is due. Past half, weigh it against the trade-in figure, the payment on a replacement and the mileage left. A $4,940 transmission on a car worth $7,000 is 71 percent of its value, the point to run the repair or replace calculator before you purchase anything.
Two costs fall outside any estimate. Work under the manufacturer’s warranty or a recall costs you nothing, so check coverage by VIN first. After an accident, the loss in value is separate: a free diminished value appraisal compares the market value after an accident with the value before it, and insurance companies may owe that gap in a diminished value claim.
More Detailed Cost Tools
For options the quick version skips, open the system page: Brakes, AC, Engine, Transmission or Body work.
Start with the car repair calculator at the top of this page and note the typical figure for your state and garage. Then get a written estimate and review it against the low to high range. One far above the high column deserves a line-by-line breakdown and a second opinion (see how much car repairs should cost). Keep the invoice and other paperwork as documentation in case a warranty or insurance reimbursement comes up.
Questions About the Free Estimate
How is a car repair estimate calculated?
Book hours times the hourly rate, plus parts at retail, fluids or materials, and a supplies charge. This tool starts from $132 an hour nationally and adjusts for state, vehicle class and type of garage.
How much more does a dealer charge than an independent shop?
About 25 percent more per labor hour, $165 against $132, per AAA’s 2026 guide. This tool also adds 25 percent to dealer parts, a planning estimate, which moves front pads and rotors from $480 to $600.
What is the most expensive part of a car to repair?
The transmission and engine. A remanufactured automatic installed runs about $4,940 at baseline, a used 4 cylinder engine about $3,575. A whole-car metallic respray is close, about $3,600.
