Deductible vs Reimbursement: How Pet Policy Terms Trade Off
The deductible is a fixed amount the owner pays each policy year before the insurer pays anything; the reimbursement share is the percentage of the rest the insurer pays back. A higher deductible costs most on small bills, a lower reimbursement share costs most on large ones. The annual limit only matters in a year with very large bills, and it is the term with the clearest published price difference.
The arithmetic
Payout = (covered bills − deductible) × reimbursement share, up to the annual limit. On Trupanion's published average claim for a cruciate ligament tear, $5,439:
| Deductible | Reimbursement | Policy pays | Owner pays |
|---|---|---|---|
| $250 | 90% | $4,670 | $769 |
| $250 | 80% | $4,151 | $1,288 |
| $250 | 70% | $3,632 | $1,807 |
| $500 | 80% | $3,951 | $1,488 |
| $1,000 | 80% | $3,551 | $1,888 |
On a small bill the deductible dominates. Fetch's published oral surgery claim was $620: with a $500 deductible the policy pays $108 at 90%, and with a $250 deductible $333.
What the annual limit costs
Forbes Advisor priced the same 3-year-old pet ($250 deductible, 80% reimbursement) at a $5,000 limit and with no limit. For a Labrador Retriever the averages are $56 and $76 a month, 36% more for unlimited. Across the 4 dog ages it published, the gap runs from $41 versus $64 at 3 years to $74 versus $114 at 7 years.
A $5,000 limit is reached at a covered bill of $250 + $5,000 ÷ 80% = $6,500; Trupanion's published averages for diabetes ($10,496) and hip dysplasia ($7,815) are both above it.
Break-even moves with the terms
The covered bill at which a year of premiums plus the owner's share equals the bill is deductible + 12 × premium ÷ reimbursement. At NAPHIA's 2025 dog average of $69.67 a month: $1,179 at $250 and 90%, $1,295 at $250 and 80%, $1,694 at $500 and 70%. A higher deductible usually comes with a lower premium, which this table holds fixed; the calculator lets both move. Breed figures are on cost by breed and state figures on cost by state.

Questions
Is a higher deductible or a lower reimbursement better?
Neither is better in general. A higher deductible cuts every year's payout by a fixed amount; a lower reimbursement share cuts every dollar above the deductible. Which costs more depends on the size of the bills.
How much more does unlimited pet insurance cost?
In Forbes Advisor's published averages for a 3-year-old dog with a $250 deductible and 80% reimbursement, the unlimited limit cost more than the $5,000 limit in every breed it lists, for example $56 against $76 a month for a Labrador Retriever.
