How Mercury scores
Each category is scored against a published figure, then weighted into the overall score. Where a figure is not published, we say so rather than estimate one.

The full review
Mercury General writes in 11 states with its business heavily concentrated in California, and holds 0.94% of the national private passenger auto market on 2024 premiums. Reading its national average premium as a verdict on the company misses the point: Mercury exists to compete in a handful of markets, and California is the one that matters.
Why California changes the comparison
California's regulatory regime strips out much of what national carriers compete on. Progressive's Snapshot, its paperless, pay-in-full, autopay, continuous-insurance, teen-driver, good-student and sign-online discounts are all unavailable there. Nine of Travelers' eleven discounts do not apply. Geico's DriveEasy and Claim Forgiveness are excluded, as are Allstate's Drivewise savings. Against that backdrop a California-focused carrier competes on very different terms than the national averages suggest.
The national number
$3,472 a year for full coverage on our benchmark profile, 47% above the $2,356 national average — the second-highest figure in this review. Outside California that is difficult to justify against Geico, Travelers or State Farm.
Two telematics programs, not one
Mercury runs RealDrive, a mileage-based program tied to odometer readings and published at up to 20% additional savings, and MercuryGO, an app-based behavior program available in Arizona, Florida, Georgia, Illinois, Nevada, New Jersey, Oklahoma, Texas and Virginia. MercuryGO offers both a driving discount and a participation discount, though Mercury publishes no percentage for either.
AM Best affirmed Mercury's A (Excellent) rating in February 2026 and revised the outlook from negative back to stable, citing policyholder surplus up $362 million to $2.4 billion and a 96.3% combined ratio for 2025 — achieved despite the wildfires.
Mercury also expanded its catastrophe reinsurance tower from $1.29 billion to $2.14 billion in July 2025. For a carrier this concentrated in California, that is the number worth watching.
How claims go
701 out of 1,000 in the J.D. Power 2025 study, one point above the segment average — average by any reasonable reading. Its complaint record is worse: more complaints than expected for its size, on 2021–2023 data. That window predates the wildfire claims surge, so the current picture may differ in either direction.
Mercury is a regional carrier whose national average premium does not represent what it is for. In California — where it writes most of its business and where many national carriers strip out their best discounts — it is a genuine contender. Outside California the case is much weaker: 47% above average, an average claims score, and a complaint record pointing the wrong way.

Mercury questions, answered
The things people actually ask before switching.
Where Mercury sits in the market
No published rate data, so no honest position on the horizontal axis: Liberty Mutual, NJM, Clearcover, Elephant, Lemonade, Root, Texas Farm Bureau. Below the J.D. Power study’s size threshold, so no position on the vertical axis: Kemper, Shelter, Chubb, COUNTRY Financial, MAPFRE, Plymouth Rock, The Hanover. That study samples only the largest insurers, so these carriers will not appear in a future wave either. Premiums from NerdWallet’s August 2026 analysis; claims scores from the J.D. Power 2025 U.S. Auto Claims Satisfaction Study. USAA is scored but not ranked in that study because it serves the military community only.
Not plotted, because no public rate data exists for them: Liberty Mutual, NJM, Clearcover, Elephant, Lemonade, Root, Texas Farm Bureau. Complaint bands from NerdWallet’s analysis of NAIC complaint data, 2022–2024 (2021–2023 for Liberty Mutual and Mercury). We show the band rather than a numeric complaint index on purpose — the per-carrier indexes published by different compilers contradict each other badly enough to be unusable, because the index is reported per underwriting subsidiary and most sources do not say which one they used.
