About this tool

Bringing home a pet is a long commitment, and the price of the pet itself is only the start. Food, routine vet care, vaccines, flea and tick prevention, grooming, toys, insurance, boarding and emergencies add up. This calculator uses typical starting figures that you can change to match your local prices, then shows monthly, yearly and lifetime totals.

Costs vary a lot by country, city, breed and size. Large dogs eat more and need larger doses of medication, while some breeds are prone to expensive health problems. Many owners set aside an emergency fund or buy pet insurance to avoid difficult decisions if something unexpected happens.

Use the result for budgeting and to compare adopting a dog, a cat, or waiting until you are ready. All figures are estimates.
