About RepairMath

What this site is

RepairMath publishes fair-price ranges for common car repairs, computed from a transparent model — labor hours × your state's shop rate + realistic parts bands — instead of the "call for a quote" opacity that dominates the industry. Every estimate shows its inputs, every guide lists the add-on lines shops append to quotes and the legitimate trigger for each, and the whole model is documented on the methodology page, including its limits.

What this site is not

We are not a shop-referral service. Sites that hand your phone number to repair shops get paid by those shops, and that incentive quietly shapes their numbers. RepairMath doesn't collect leads, doesn't sell contact information, and doesn't take referral fees — which is precisely why we can publish ranges without flattering anyone.

How the site is made

Content is researched and drafted with the help of AI tooling, working from published labor-time guides, shop-rate surveys, and parts-market data, and is reviewed for technical accuracy before publication. Estimates are labeled with the model date they were built from and are recalibrated as readers submit real-world quotes. When something is an estimate rather than a fact, the page says so. Corrections are published in place — if you find an error, use the contact page and we'll fix it publicly.

Who it's for

Anyone holding a repair quote and a feeling. The feeling is usually right — but it needs numbers to become a negotiation. Our job is the numbers.
