State-level pet insurance pricing is published less consistently than the headline national average, but the variation is wide enough that the buyer in California, New York, or Massachusetts is paying a substantially different premium than the buyer in Mississippi, Iowa, or West Virginia for the same coverage shape. On the cited NAPHIA industry data, the US dog accident-and-illness average sat at $749.29 a year in 2024 and the cat average at $386.47 [NAPHIA: North American Pet Health Insurance Industry Market Reaches $5.2B in Written Premium, 2025-04]. NAPHIA does not publish per-state averages, so the state spread on this page is described by cost of care, not by a published table.
That spread is structural. Pet insurance is priced state by state because vet costs are priced state by state, and a policy is priced to the cost of the claims it will pay.
The state-level spread
The cited NAPHIA average for dog accident-and-illness coverage in 2024 was $749.29 a year nationally [NAPHIA: North American Pet Health Insurance Industry Market Reaches $5.2B in Written Premium, 2025-04]. Without a published state table, the distribution around that average is best described in three broad bands by cost of care:
The high band clusters in the high-cost-of-care markets: California (especially the Bay Area and Los Angeles metro), New York (especially Manhattan and surrounding boroughs), Massachusetts, Washington (Puget Sound), New Jersey, and Connecticut. Specialty-hospital density and labor cost are the dominant drivers in these markets; CareCredit's cited range for a dog cruciate repair runs $2,793 to $6,417 depending on location [CareCredit: How Much Does CCL (ACL) Surgery for Dogs Cost?, 2025].
The middle band covers most of the country: the bulk of the Midwest, the inland West, the Mid-Atlantic, and the lower-cost coastal metros (Tampa, Charlotte, Raleigh, Phoenix outside metro Phoenix proper).
The low band clusters in the lower-cost-of-care states: Mississippi, Alabama, Arkansas, Iowa, West Virginia, Kentucky, much of the rural Midwest. Vet labor and overhead are lower; specialty-hospital density is lower; the policy is priced to a cheaper expected claim. The cat-policy spread follows the same cost-of-care logic around a lower national average of $386.47 [NAPHIA: North American Pet Health Insurance Industry Market Reaches $5.2B in Written Premium, 2025-04].
The state spread is the single largest source of variation in a pet insurance quote at a given coverage shape, larger than the difference between two carriers at the same coverage shape in the same state.
What drives the geography
Three factors drive the state-level spread, and they are the same factors that drive geographic variation in human medical pricing.
The first and largest is veterinary cost-of-care density. A premium is priced to the claims the policy expects to pay, and a state where the average specialty cruciate repair, cancer protocol, or GDV surgery costs more than the national average prices the corresponding policy higher. CareCredit's 2025 cost research, conducted by ASQ360 across all 50 states and DC for the published surgical procedures, shows a wide per-procedure spread by location [CareCredit: How Much Does CCL (ACL) Surgery for Dogs Cost?, 2025].
The second is specialty-hospital density and the policyholder mix. States with dense specialty-care networks see a higher fraction of claims routed to specialty hospitals, which price above general practices. A state with little specialty-care density has a policyholder mix that primarily files general-practice claims, and the premium reflects that. This is the structural reason the same coverage costs less in rural states even after vet cost-of-care normalizes.
The third is regulatory and competitive mix. State insurance regulators set the rate-filing process and the disclosures carriers must publish; the most active state filings (California, New York, Florida, Texas) generate the most-public data and the most competitive carrier mixes. States with thinner regulatory data and fewer competing filings can run pricier in absolute terms because carriers face less rate pressure, although the variation here is smaller than the cost-of-care effect.
Against the cited NAPHIA 2024 national averages ($749.29 a year for dog accident-and-illness, $386.47 a year for cat), a state's premiums run above or below the national figure with local cost of care [NAPHIA: North American Pet Health Insurance Industry Market Reaches $5.2B in Written Premium, 2025-04]. NAPHIA publishes no state-level spread to size that gap. The geography is the term that dominates.
The cat policy spread tracks the same geography, scaled down, with one caveat: indoor-cat policies are priced largely off general-practice cost rather than specialty cost (cats see fewer surgical claims), so the cat spread is somewhat narrower in absolute dollar terms than the dog spread.
Where to look up your state
State-level premium averages are not published as a clean public table by NAPHIA at the per-state level. The defensible path for a buyer is to run a quote at the exact ZIP code and pet age at two or three reviewed carriers, then compare against the national average to see which band the state lands in. A quote materially above the $749.29 dog or $386.47 cat NAPHIA national average is the state, not the carrier [NAPHIA: North American Pet Health Insurance Industry Market Reaches $5.2B in Written Premium, 2025-04].
