How much does pet insurance cost per month?
This tool starts from a typical base premium for dogs or cats, then adjusts for your pet's age, coverage type (comprehensive vs accident-only) and annual payout limit.
How Is Monthly Premium Calculated
The estimate above runs a simple multiplication: a base premium for the species, times an age factor, times a coverage factor, times an annual-limit factor.
Monthly premium = base premium × age factor × coverage factor × annual-limit factor.
The base premiums
This calculator starts dogs at $38 a month and cats at $24 a month before any adjustment. Dogs cost more on average because they tend to run larger claims for orthopedic issues, foreign-object surgery and cancer treatment.
Worked example: a young dog, comprehensive, $5,000 limit
A dog under 2 with comprehensive coverage and a $5,000 annual limit uses the lowest age factor and the baseline coverage and limit factors: $38 × 0.85 × 1.00 × 1.00 = about $32 a month, or roughly $384 a year.
Worked example: an older cat, accident-only, $10,000 limit
A cat age 10 or older with accident-only coverage and a $10,000 limit uses the highest age factor, the lower coverage factor and a raised limit factor: $24 × 2.00 × 0.55 × 1.25 = about $33 a month, or roughly $396 a year. Notice that even with a cheaper accident-only tier, age and a higher limit can land you close to what a younger pet pays for full comprehensive coverage.
Multiplier reference
| Life stage | Age factor |
|---|---|
| Under 2 | 0.85 |
| 2 to 5 | 1.00 |
| 6 to 9 | 1.40 |
| 10 and older | 2.00 |
| Coverage tier | Factor |
|---|---|
| Comprehensive (accident + illness) | 1.00 |
| Accident-only | 0.55 |
| Annual limit | Factor |
|---|---|
| $5,000 | 1.00 |
| $10,000 | 1.25 |
| Unlimited | 1.45 |
These are the exact multipliers used by the calculator above, not a separate industry average.
Things To Know Before You Buy
Breed and ZIP code push real quotes up or down more than this model can capture; large or brachycephalic breeds and high-cost-of-living areas typically cost more than these estimates. Deductible choice also matters: a higher deductible lowers your premium but raises what you pay before reimbursement kicks in.
The cheapest time to insure a pet is while it is young and healthy, before any condition becomes a pre-existing exclusion. Premiums still rise with age, but starting early keeps more conditions covered from day one.
