Is Pet Insurance Worth It?

Scenario Math
If major surgery needed $4,000 surgery - $500 deductible - (80% coverage) = You pay $1,300 vs. $4,000
Lifetime premiums (dog) ~$6,000-$12,000 over 12 years
Break-even 1-2 major emergencies usually covers lifetime premiums

Lifetime Pet Costs

Pet Lifespan Total Lifetime Cost
Small dog 12-16 years $15,000-$25,000
Medium dog 10-14 years $20,000-$35,000
Large dog 8-12 years $25,000-$40,000
Giant dog 6-10 years $30,000-$55,000
Indoor cat 15-20 years $12,000-$25,000
