How Much Does It Cost To Own A Pet?

Key Takeaways
Pet Ownership Costs More Than Most People Expect
Dogs can cost $1,500 or more per year. Cats run about $800 annually. Even smaller pets like fish, geckos, and birds carry ongoing expenses for food, supplies, and veterinary care that add up quickly. Before bringing a pet home, understanding the true yearly cost helps you budget responsibly and avoid financial surprises down the road.
The Price Tag Varies Widely by Animal
A hermit crab might cost around $180 a year to maintain, while a horse can run close to $3,800 annually. The article breaks down real costs for eight types of pets, from hamsters and parakeets to cats and dogs, covering food, medical care, grooming, boarding, toys, and supplies. Knowing the numbers for your specific pet helps you plan ahead.
First-Year Costs Hit the Hardest
Beyond the purchase or adoption fee, the initial setup for any pet includes cages, tanks, bedding, food bowls, and a first vet visit. For dogs, that first-year investment can top $1,500. For cats, expect around $1,200 upfront. Even a simple betta fish setup runs about $160 before you buy the first container of food. The ongoing annual costs are lower, but that first year is where most new pet owners get caught off guard.
Adding a pet to the family can be one of the most rewarding experiences—and the most shocking to the wallet. Do you know how much owning a dog, cat, horse or other pet costs per year? Take a look at these annual estimates for common household pets:

Hermit Crabs | ~$80 initially, plus $180+ annually
Perhaps the least expensive pet you can own (other than a pet rock), supplies, food and toys for hermit crabs are cheaper than a fancy crab dinner. Plan to spend at least $40 on cage setup, up to $25 to purchase/adopt, and monthly food and supplies around $15-$20. Veterinary (if needed) care can run you around $50 on average.

Gerbils and Hamsters | ~$180 initially, plus $150+ annually
Plan to spend at least $160 in starting costs for setting up the enclosure, including supplies and toys. Purchasing from a reputable pet store will run you an average of $20-$25. You’ll likely spend an average of $150 per year on litter, bedding and food. Veterinary care (if needed) varies between $70-$300.

Fish | ~$160 initially, plus $520 annually
While needs vary depending on the kind of fish you get, let’s take a common favorite among amateur fish owners: Betta Fish. Sunk costs include an aquarium, filtration equipment, heater, test kits, decorations and lighting (which can run $150 or more). Purchasing your finned friend will generally cost $5-$20, depending on species. Experts recommend a balanced diet of pellets and live/frozen food, which may run you up to $10 per week, or $520 per year.

Leopard Gecko | ~$149+ initially, plus $290+ annually
Purchase cost of your gecko plus aquarium and setup will run you between $149-$565 (including enclosure and accessories, heater, lights, bowls, hides and décor, etc.). Annual veterinary checkups will probably be $50 or more, while food and supplies will cost about $20 per month, or $240 annually.

Birds | ~$295 initially, plus $185+ annually
Despite their relatively small size, pet birds are not cheap. Even for non-exotic small birds like parakeets, expenses like cages ($70), food ($75), toys and treats ($25), medications and vet bills ($85) add up quickly.

Cats | ~$1200 initially, then $800+ per year.
Annual medical costs of $400 or more are just the beginning. Kennel and boarding fees average $337 per year, followed by food ($203), grooming ($20), toys ($23) and other supplies ($92).

Dogs | ~$1,500+ initially, plus $1,500+ annually
On average, owning a dog can cost over $1,500 per year. However, costs can vary widely based on the age, breed and health of your dog. Geography and climate can mean costly flea products. And size matters: to some degree, the bigger the dog, the higher your expenses will be.
Horses | $3,800+++
Whoa, Nelly! It’s not easy to rein in those equine expenses. Depending on whether you’re boarding or not (full-care, pasture, or self-care), total costs to keep your horse housed, fed, groomed, exercised, and regularly cared for by a veterinarian, run an average of nearly $4,000 annually … about the same average cost of a car payment.
