2026 Catalytic Converter Replacement Cost Index

Catalytic converter replacement costs $550 to $3,960 in 2026 depending on vehicle class and part type, using this site's own pricing model: aftermarket converters on standard cars sit at the low end, and OEM converters on luxury or hybrid vehicles sit at the high end. Independent estimators put the national average closer to $2,283 to $2,473 including labor, and parts typically account for 80 to 95 percent of the bill on most vehicles.

Summary: cost by vehicle class and part type

These figures come directly from this site's own calculator model (national-average ZIP adjustment, one converter unless noted). See the methodology section below for how each number was derived.

Ranges include parts and labor, and assume a ZIP code in an average-cost market. High-cost metro ZIP codes (parts of New York, San Francisco, and Los Angeles) run 20 to 35 percent above these figures in the calculator; some rural and Midwest ZIP codes run 8 to 10 percent below.

Parts vs. labor, by vehicle

The split between parts and labor swings hard by vehicle. A dense, precious-metal-heavy converter on an economy car can be nearly all parts cost; a converter that is difficult to access on a performance sedan can flip the split toward labor.

Methodology

The vehicle-class table is derived directly from this site's own calculator pricing model: a base range of $1,000 to $2,200 for one OEM converter on a standard car in an average-cost ZIP code, adjusted by the calculator's own multipliers for part type (aftermarket × 0.55), vehicle class (SUV/truck × 1.3, luxury/hybrid × 1.8), and converter count (two converters × 1.9). Those multipliers are read straight from the calculator's source code, not re-estimated.

The parts-vs-labor and OEM-vs-aftermarket figures are cited from three independent, named primary sources so the site-model numbers can be checked against real-world estimators:

• RepairPal, "Catalytic Converter Replacement Cost Estimate" (repairpal.com/estimator/catalytic-converter-replacement-cost), accessed July 2, 2026.
• ConsumerAffairs, "Cost to Replace a Catalytic Converter" (consumeraffairs.com), updated February 24, 2026, citing a survey of five mechanics and RepairPal's per-vehicle data.
• Kelley Blue Book, "Catalytic Converter Theft: Tips to Keeping Your Car Safe" (kbb.com/car-advice/catalytic-converter-theft/), last modified June 14, 2026.

This index is scheduled for an annual refresh. Figures reflect general U.S. pricing; your actual quote depends on your specific vehicle, converter count, and local labor rates. Get a written quote from a licensed mechanic before approving any work.
