How the Pet Food Cost Calculator works
Days per bag = bag weight in grams ÷ (daily portion × number of pets). Cost per day = bag price ÷ days per bag, then it is scaled to 30 days and 365 days. Use the portion from your daily calorie estimate or the feeding chart on the bag, and remember that treats and toppers add to the real bill. Example: A $45 bag of 15 kg fed at 300 g a day to one pet lasts 50 days and costs $0.90 a day, about $27.00 a month.
