Is Pet Insurance Worth It? The Break-Even Math
Pet insurance costs less than paying the vet directly only in a year when covered bills pass the break-even point: the deductible plus twelve months of premiums divided by the reimbursement share. At NAPHIA's 2025 average dog premium ($69.67 a month) with a $250 deductible and 80% reimbursement, that is $1,295 of covered bills in a year; for the average cat ($36.25) it is $794. In a year below that, the premiums cost more than the policy pays back. This is arithmetic, not advice: the value of cover against a rare large bill is a judgement for the owner.
The formula
Insured year = 12 × premium + (bill − payout), where payout = (bill − deductible) × share. Setting that equal to the bill gives break-even bill = deductible + 12 × premium ÷ share. Check at $1,295: the policy pays ($1,295 − $250) × 80% = $836, exactly the $836 of premiums.
Against published bills
| Published figure | Amount | Insured year at the dog average | Uninsured |
|---|---|---|---|
| Healthy Paws average reimbursement per claim, 2025 | $392.04 | $1,114 | $392 |
| Trupanion: seizures | $1,984 | $1,433 | $1,984 |
| Trupanion: foreign body ingestion | $2,964 | $1,629 | $2,964 |
| Trupanion: cruciate ligament tear | $5,439 | $2,124 | $5,439 |
| Trupanion: diabetes | $10,496 | $3,135 | $10,496 |
The Healthy Paws figure is a reimbursement already paid, not a bill, so it understates the bill behind it; it shows that a typical single claim is far below break-even, while the condition averages Trupanion publishes are well above it.
Saving instead
Putting the same $69.67 a month aside builds $836 a year. Trupanion's average cruciate ligament claim of $5,439 is 78.1 months of that saving. Insurance spreads the risk of that bill arriving in the first year; saving keeps the money if it never arrives. Breeds the American College of Veterinary Surgeons links to costly conditions are listed under health problems by breed, and every published breed premium is under cost by breed.
