This pet cost calculator adds up what a dog, cat or other pet really costs: food, vet visits, preventive care, insurance, grooming, boarding and one-time costs such as adoption and spaying or neutering. It shows the monthly, first-year and lifetime cost, with room for an emergency fund.
| Item | Cost | Times a year |
|---|---|---|
Costs to plan for
- One-time: adoption or purchase, spay or neuter, microchip, crate, bed, bowls and a carrier.
- Monthly: food, treats, flea, tick and heartworm prevention, and pet insurance.
- Yearly: check-ups, vaccines, dental care, licences and boarding or pet-sitting.
- Unexpected: emergency vet bills can run into the thousands, so keep a fund or insurance.
Worked example
With the example costs in the calculator, ongoing costs are about $2,810 a year ($234 a month). Adding $800 of one-time costs makes the first year about $3,610, and over 12 years, with costs rising 3% a year, the lifetime total is about $40,680.
Ways to save
- Adopt from a shelter, where vaccines and spaying or neutering are often included.
- Keep up with preventive care and dental cleaning to avoid larger bills later.
- Compare pet insurance plans, deductibles and reimbursement rates before your pet is older.
- Buy food in bulk and learn basic grooming at home.
Frequently asked questions
Is a cat cheaper than a dog?
Usually, because cats eat less and rarely need grooming or boarding at the same level, but vet costs can be similar.
Is pet insurance worth it?
It can be if a large unexpected bill would be hard to pay. Compare premiums, deductibles, exclusions and pre-existing condition rules.
What is the biggest pet expense?
For many owners, food and routine vet care each year, but one emergency or illness can cost more than a whole year of routine care.
How much should I keep in a pet emergency fund?
Many owners aim for $1,000 to $3,000, or enough to cover their insurance deductible and co-pay.
