The Renewal Math Your Insurer’s Explanation Leaves Out

Your pet insurance premium may have risen partly to cover higher veterinary claims, but the latest public numbers do not support treating every increase as a dollar-for-dollar pass-through. At Trupanion, adjusted operating income rose 24% year over year in the second quarter of 2026 while average monthly revenue per pet rose 9%—profit growth running nearly three times as fast as the per-pet price measure (Trupanion’s Q2 2026 earnings-call transcript). That does not prove your renewal is unjustified, but it does mean “vet costs went up” is the start of the explanation, not the end.

Industry figures point in the same direction. From 2024 to 2025, North American gross written pet-insurance premium grew 19.4% to $6.2 billion while insured pets grew 8.5%, from 7.03 million to 7.6 million. Premium growth therefore ran about 2.3 times as fast as pet-count growth, implying roughly 10% more premium per insured pet before accounting for changes in coverage and customer mix (NAPHIA’s 2026 industry data).

The Vet-Cost Explanation Is Partly Right

Veterinary treatment can become more expensive because of specialist and emergency care, advanced diagnostics, medication, equipment, staffing and longer treatment for chronic conditions. When covered invoices rise, an insurer can reasonably expect future claims to rise as well.

Your own claim-free year does not settle the issue. Insurance pools risk across many customers, and a company may reprice a geographic area, age group, breed category or product even when one pet had no claims. Pets Best, for example, says it does not increase an individual customer’s premium because that customer filed a claim, while still listing age, location and rising veterinary costs among its pricing factors (Pets Best’s explanation of premium factors). Practices vary by insurer, product and jurisdiction.

The limitation is that a valid cost pressure does not establish the size of a justified increase. Trupanion management said its pricing was aligned with double-digit veterinary inflation, yet its average monthly subscription revenue per pet reached $87.44, up 9%, while total adjusted operating income reached $43.3 million, up 24%. Subscription adjusted operating income was $41.4 million, also up 24%.

CEO Margaret Tooth described the result as improving unit economics through “disciplined execution” and pricing better aligned with the value of coverage. Management also said the lifetime value of enrolled pets rose 25% during the quarter. Alongside the results, Trupanion’s regulated insurance entity paid a state-regulator-approved $44 million dividend to its operating company, and the board authorized a new $100 million share-repurchase program (Trupanion’s Q2 2026 transcript).

Those are figures from one public insurer, not a market-wide finding about every company or a diagnosis of your policy. Average revenue per pet also is not the same as an individual renewal increase. The evidence supports a narrower verdict: at least one major insurer’s profit metric expanded substantially faster than the amount collected per pet, so owners should not assume every renewal dollar merely offsets higher claims.

Enter your old premium, renewal increase and paid claims; the result compares your renewal with the latest public pricing and profit benchmarks.

Start With Your Exact Renewal Increase

Compare annual totals rather than monthly installments, which can be affected by billing frequency or fees. The percentage increase equals the new annual premium minus the old annual premium, divided by the old annual premium, multiplied by 100.

If the annual premium increased from $720 to $900, the dollar increase is $180 and the percentage increase is 25%. That calculation measures the change; it does not explain it or determine whether applicable notice, filing or policy requirements were followed.

Use the 9% Trupanion revenue-per-pet increase and the roughly 10% industry premium-per-pet change as scrutiny benchmarks, not universal limits. An increase above them deserves a specific explanation. An increase below them can still be wrong if the insurer used incorrect information, removed a discount or changed coverage without your understanding.

The industry figures also require care:

2024–2025 Measure	Earlier Figure	Later Figure	Growth
Gross written premium	—	$6.2B	19.4%
Insured pets	7.03M	7.6M	8.5%
Implied premium per pet	—	—	~10%

NAPHIA says its data represents approximately 99% of written pet health-insurance premiums in the United States and Canada. Gross premium can change because of prices, enrollment timing, coverage levels and shifts in the mix of products, locations, ages, dogs and cats. It is not proof that an individual renewal should rise 19.4%.

Ask For The Loss-Ratio And Rate-Change Math

Ask the insurer to identify the rating factors that changed and to quantify each one if it can. A useful written request is:

Please identify the rating factors, policy changes, discounts, fees or broader rate adjustment that affected this renewal. Please provide the applicable product or policy-block loss ratio, if available, and explain whether it increased or decreased. If an approved rate filing applies, please provide its reference and effective date. Also confirm whether my pet’s age, claims, medical history, breed information or address affected the price.

The draft evidence does not provide a current industry-wide loss ratio, so there is no responsible universal figure to use as a benchmark. Your paid claims divided by premium are also not the insurer’s formal loss ratio: that personal calculation omits pooled claims, reserves and other policyholders. It remains useful when testing a vague explanation. A claim-free customer facing a 20% increase should receive something more specific than a reference to that pet’s past care.

Collect the prior and renewal declarations pages, renewal notice, policy form, endorsements, billing statements and discount notices. Save copies rather than relying on an account screen that may change.

Then establish whether the increase began at annual renewal or after an address correction, move, benefit change, payment-frequency change, addition or removal of a pet, or correction to the pet’s information. A midterm change should match an account action, endorsement or documented correction.

Separate Rate Changes From Coverage And Billing Changes

Compare the old and new policy line by line. Record:

• Annual base premium and total billed amount
• Deductible amount and whether it is annual, per condition or per incident
• Reimbursement percentage and calculation method
• Annual, lifetime and per-condition limits
• Exam-fee, prescription and diagnostic coverage
• Hereditary, congenital and chronic-condition terms
• Wellness riders and other optional benefits
• Discounts, installment charges, fees, taxes and assessments
• Payment frequency
• Pet age, breed, species and other recorded details
• Residential address and ZIP code

A benefit summary can appear unchanged while an endorsement alters a definition or exclusion. Conversely, the underlying insurance rate may be unchanged while an expired discount, installment fee or optional rider raises the bill.

Verify the reimbursement method rather than relying on a headline percentage. A policy advertising 80% reimbursement may not pay 80% of the total invoice if exam fees, noncovered services or amounts above an applicable schedule are excluded.

Check the deductible structure too. A $500 annual deductible and a $500 per-condition deductible create different exposure. Ask whether deductible progress resets at renewal and whether any midyear policy modification affects it.

Claims May Matter Differently Across Insurers

A healthy pet and claim-free year do not guarantee a stable premium. The insurer may have repriced a broader age, breed, location or product group, or changed assumptions about future treatment costs.

Whether an individual pet’s claims can affect renewal pricing is a separate question. Pets Best says an individual claim does not cause that customer’s premium to increase. British Pet Insurance says previous or expected claims may affect renewal pricing in some circumstances (the UK insurer’s claims explanation). The latter is a UK example and should not be assumed to describe a US policy.

Ask these questions in writing:

• Does this policy permit individual claims history to affect renewal pricing?
• Did any claim or medical condition affect this specific renewal?
• Did broader claims experience affect the rate?
• Which policy term, rating rule or filing permits the factor?
• What loss ratio or claims-cost change supported the increase?

Do not infer that a diagnosis caused the increase unless the insurer and governing documents establish that connection.

Price Each Coverage Concession Separately

Ask the current insurer for separate quotes before canceling. A higher deductible, lower reimbursement percentage, lower annual limit, removed wellness rider or accident-only policy may reduce the premium, but each shifts cost or risk back to you.

Change	Likely Trade-Off	Number To Compare
Higher deductible	More paid before reimbursement	Saving versus added deductible
Lower reimbursement	Larger share of eligible bills	Saving versus added coinsurance
Lower annual limit	Coverage stops sooner	Saving versus large-claim exposure
Remove wellness rider	Routine allowances disappear	Rider cost versus expected benefits
Accident-only cover	Illness coverage disappears	Saving versus illness exposure

Obtain an actual quote because the draft sources provide no universal saving for any of these changes. If raising the deductible saves $120 a year but adds $500 to the amount you must pay before reimbursement, the saving is smaller than the additional exposure in a claim year. Insurer guidance confirms that higher deductibles and lower limits can reduce premiums by transferring more cost to the owner (Embrace’s coverage trade-off explanation).

Run each proposal against both a moderate eligible claim and a specified large eligible claim. Apply the contract’s actual deductible sequence, reimbursement method, exclusions and limits. Do not assume a simplified percentage if the policy uses a benefit schedule, usual-and-customary amount or per-condition cap.

Switching Can Sacrifice Existing Coverage

A cheaper quote is not necessarily equivalent. Compare deductibles, reimbursement methods, limits, fees, exam and medication coverage, hereditary and congenital-condition language, chronic and bilateral-condition rules, waiting periods and exclusions.

Medical history is the central switching risk. Symptoms, diagnoses, examinations, medication or treatment covered under the present policy may be classified as pre-existing under a replacement policy. Switching can also restart waiting periods and deductible progress (Pawlicy Advisor’s switching overview).

Give the prospective insurer complete information and request written clarification about known conditions. A quote, sales conversation or issued policy is not by itself a promise that a particular condition will be covered.

Keep the current policy active until the new policy has been issued, you know its effective date, you understand every waiting period and you know how the new insurer evaluated medical history. Ask both insurers how temporary overlap and other coverage affect claims; do not assume the same expense can be reimbursed twice.

Self-funding removes the premium but leaves you responsible for the full unpredictable bill. Compare the annual premium with emergency cash already available, the ability to replenish it and the consequences of repeated expensive events. A savings account that does not yet contain the needed amount is not equivalent protection.

Escalate Errors And Unclear Explanations

Save renewal notices, declarations pages, endorsements, revised quotes, emails, chat transcripts, representative names and call-reference numbers. If recorded information is wrong, request a correction and a recalculated quote rather than assuming the correction will reduce the price.

If the insurer will not explain the change, appears to have used incorrect information or may have missed a required notice, contact the insurance regulator for the policy’s jurisdiction. Rules differ by location. California, for example, introduced state-specific transparency and rate-oversight requirements taking effect in 2025, but those provisions should not be assumed to apply nationwide (NBC 7 San Diego’s report on California oversight). Consult the relevant regulator for current requirements.

A steep renewal is not automatic proof of an error or excess profit. It is evidence that the insurer should show its work. Compare your increase with the 9% per-pet revenue benchmark, examine your own paid claims without mistaking them for a formal loss ratio, verify every policy and billing field, and ask what happened to the applicable loss ratio. Higher veterinary costs may be real while profit grows faster still.
