Founder, CalcScrape · LinkedIn

I build and maintain every calculator on this site. I am not a mechanic: the pages are built on public government records (NHTSA owner complaints, recalls, service bulletins and warranty extensions) that I download and process myself. The written sections are drafted with AI from that data only, fact-checked against it by a second AI model, and then checked by automated gates that remove any number not found in the data or the calculator. The calculators themselves are hand-built formulas, not AI output.

I have no affiliate relationships with repair shops, parts sellers, or warranty companies. The site is supported by display ads; ads never change a number on a page.

What We Cover

Automotive repair and ownership costs: brakes, tires, engine, transmission, suspension, electrical, and car financing — with inputs for vehicle type, shop type, and parts grade so the estimate reflects your situation.

Where the Numbers Come From

Mechanic wages come from the BLS Occupational Employment and Wage Statistics survey. The state adjustment uses BEA Regional Price Parities. Recall and complaint data on the research pages come from NHTSA. Shop labor rates and parts prices have no government source, so they are market estimates and are labeled that way on each page. Every page lists its sources at the bottom. The methodology page explains each source and how the estimates are built.

Limitations

These are estimates. National averages don't capture your exact vehicle, your shop's labor rate, or what a technician finds once the car is on the lift. Use the estimate to check a quote, then get a written quote from a local shop before you authorize work. Nothing on this site is professional mechanical or financial advice.
