What Is the Dog Food Cost Calculator?
Calculate your monthly and annual dog food cost — and compare the true cost per calorie of different foods.
Premium dog foods often appear expensive — but when you calculate cost per calorie or per kilogram of dry matter, they can be more economical than budget brands because your dog needs less of them. This calculator works out the real monthly cost of feeding your dog and lets you compare foods on a true cost-per-serving basis.
Every result is based on published veterinary research and breed-size-specific growth data — not generic averages. This tool is completely free, works instantly in your browser, and requires no account or sign-up.

How It Works
Cost comparison between dog foods is misleading without normalisation. A budget food at £1/kg may require 300g per day to meet a dog's needs, while a premium food at £3/kg may only require 150g per day due to higher caloric density. The premium food costs more per kg but the same or less per day. This calculator computes cost per day, per month, per year, and per 100 kcal to allow fair comparison.
Veterinary Research
Every formula is derived from peer-reviewed veterinary studies and clinical guidelines, not guesswork or generic rules.
