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, and the state-level spread around those averages stretches from roughly 60% of the national figure in the cheapest states to about 150% in the most expensive ones [NAPHIA: Section 3, Average Premiums, 2024].
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: Section 3, Average Premiums, 2024]. The state-level distribution around that average runs in three broad bands on the published carrier filings and consumer-finance press tracking the same data:
The high band (roughly $1,000 a year and above for the same coverage shape) 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; a Bay Area specialty cruciate repair lands toward the $6,417 ceiling of CareCredit's $2,793-to-$6,417 cited range, while a comparable Iowa case lands toward the floor [CareCredit: How Much Does CCL (ACL) Surgery for Dogs Cost?, 2025].
The middle band (roughly $600 to $900 a year) 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 reviewed-set average premium lands inside this band in most state filings.
The low band (roughly $450 to $600 a year) 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 tracks the same shape on the same NAPHIA data, scaled down to the cat $386.47 average [NAPHIA: Section 3, Average Premiums, 2024].
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 20-40% more than the national average prices the corresponding policy 20-40% higher. CareCredit's 2025 cost research, conducted by ASQ360 across all 50 states and DC for the published surgical procedures, shows comparable per-procedure spread that maps almost cleanly onto the premium spread [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), the state-level spread runs roughly $450 to $1,100 for dogs and proportionally for cats [NAPHIA: Section 3, Average Premiums, 2024]. A buyer comparing two carriers in the same state is comparing variations of a few percent. A buyer comparing the same carrier across two states can see a 2x premium difference. 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: Section 3, Average Premiums, 2024].
