What's included in this estimate
Ongoing annual costs cover food, routine vet visits, supplies, and everyday extras. First-year costs add one-time expenses: adoption or purchase fees, spay/neuter surgery, initial vaccines, and starter supplies like a crate, bed, and leash or litter box. Optional add-ons like pet insurance and professional grooming are shown separately so you can toggle them on or off.
Costs vary a lot by location and choices
Vet prices, food quality, and grooming rates vary significantly by region and by the choices you make. Treat this as a starting budget, not a quote — and build in a buffer for unexpected vet visits, which are the most common source of surprise costs in pet ownership.

Quick reference: typical yearly cost
Base figures used by this calculator, before optional insurance or grooming.
| Pet | Ongoing annual cost | First year (incl. one-time costs) |
|---|---|---|
| Small dog (up to 20 lbs) | $1,000 | $2,050 |
| Medium dog (21–50 lbs) | $1,300 | $2,350 |
| Large dog (51–90 lbs) | $1,650 | $2,700 |
| Giant dog (over 90 lbs) | $2,050 | $3,100 |
| Cat | $900 | $1,700 |
Pet insurance adds about $600 a year. Professional grooming adds about $400 a year for a dog, $200 for a cat.
Frequently asked questions
How much does a dog cost per year?
Between roughly $1,000 and $2,050 a year depending on adult size, covering food, routine veterinary care, supplies, and everyday extras. Larger dogs cost more across almost every category, because food, medication doses, and boarding rates all scale with body weight.
Why is the first year so much more expensive?
One-time costs land in year one: adoption or purchase fees, spay or neuter surgery, the initial vaccine series, microchipping, and starter equipment such as a crate, bed, carrier, or litter box. Those add roughly $1,050 for a dog and $800 for a cat on top of the ongoing annual cost.
Are cats cheaper than dogs?
Usually, yes. A cat runs about $900 a year against $1,000 to $2,050 for a dog, and cats avoid several dog-specific costs entirely, including boarding at typical rates, training classes, and most professional grooming. The gap narrows for a small dog and widens sharply for a giant breed.
Is pet insurance worth the cost?
It is a trade, not a saving. At roughly $600 a year it usually costs more than a healthy pet's claims, and its value is in converting a possible $6,000 emergency into a predictable monthly figure. It makes most sense if an unexpected four-figure vet bill would be genuinely difficult to absorb. A dedicated savings account is a reasonable alternative if it would not.
What costs does this calculator leave out?
Emergency and specialist veterinary care, chronic illness management, boarding and pet sitting, training beyond the basics, pet deposits on rentals, and travel costs. Unexpected veterinary bills are the single most common source of surprise expense in pet ownership, so treat the result as a floor and keep a buffer on top of it.
