Pet Cost Calculator
What does a dog or cat really cost? Honest ranges for the first year, every year after, and the whole lifetime — tuned to your food choices, your area, and services like boarding and daycare.

Your budget, decoded
The first-year setup is your main spike – one-time gear and early vet visits, not the recurring costs, are what make year one expensive.

Why year one is not a useful average
The first twelve months are the most expensive and least representative year of an animal’s life. Adoption or purchase, the initial vaccination course, spay or neuter, microchipping, and the entire one-off setup — crate, carrier, bed, bowls, litter tray, leads — all land at once. Every year afterwards is food, preventative medication, one or two routine vet visits, and replacing things as they wear out. That is usually a fraction of year one, which is why the calculator reports the two separately instead of averaging them into a single monthly figure that describes neither.
Where the numbers come from
Food and supply costs are calculated from the same product catalog behind our reviews, priced by weight rather than by bag so that changing pack size changes the answer the way it changes your bill. Veterinary and service costs are entered as ranges rather than single figures, because they vary more by geography than by anything about your pet — the same annual check-up can differ two- or three-fold between a rural practice and a city one. Where a range is wide, that reflects genuine variation rather than uncertainty about the numbers.
The costs that break budgets
This tool estimates routine ownership. It deliberately does not model emergencies, and emergencies are what actually derail pet budgets: a foreign body removal, a fracture, a sudden chronic diagnosis. Any of those can cost more in a weekend than several years of routine care. The two realistic defences are insurance bought before anything is wrong, or a dedicated savings buffer you contribute to monthly and do not touch. Our guides on pet insurance for dogs and what drives an emergency vet bill go through how to size that buffer.
Costs owners routinely forget
Three line items are missed more than any others. The first is cover for the time you are away — boarding, a sitter, or daycare — which for a household that travels can rival the food budget. The second is the housing cost of having a pet at all: pet rent, a higher deposit, or a narrower choice of rental. The third is damage and replacement during the first year with a young animal, which is not a moral failing on anyone’s part but is a real and predictable expense. Include them in your own figure even if you leave the optional fields above blank.
