Pet Cost Calculator
Estimate the monthly, yearly and lifetime cost of a pet, including food, vet care, insurance, supplies and a reserve for emergencies.
What a pet costs
A pet costs more than the purchase price. The first year includes the adoption fee, vaccines and supplies. After that come food, routine vet visits, insurance, grooming and boarding, and a yearly reserve for emergencies. Add these and multiply by the number of years to get the lifetime cost.
Costs vary a lot by animal and place. Large dogs eat and cost more at the vet than cats or small pets, and older pets cost more to treat.
