What does a dog or cat really cost per month?
Food is the number everyone guesses. Vet care, insurance, grooming, and the first-year setup are the numbers that surprise people. This adds them up honestly, with a range.

The number that gets people is the vet
Routine care (annual exam, vaccines, flea, tick, and heartworm prevention, a dental cleaning every year or two) runs $400 to $900 a year for a dog and a bit less for a cat, before anything goes wrong. When something does go wrong, a single emergency visit is commonly $1,500 to $5,000. That is the case for insurance or a dedicated pet savings account; the tool assumes one or the other, and the insurance line is where it lands if you tick the box.
Food scales with weight, not with love
A 70-pound dog eats roughly three times what a 20-pound dog eats. Fresh or premium food multiplies that again. The Dog Food Portions tool on this site does the cups-per-day math for your specific food.
First-year setup
Adoption or purchase, spay or neuter, microchip, initial vaccine series, crate, bed, leash, bowls, litter box, and the toys they will destroy. $600 to $2,000 is typical, front-loaded into the first three months, which is why the setup toggle spreads it over year one.
What is not in here
Boarding for vacations ($40 to $90 a night), training classes, pet deposits and monthly pet rent in apartments, and the big-ticket surgeries. Add a line in your budget for at least one of those a year.
