Wondering how much does it cost to feed my dog per day? The answer depends on more than just the sticker price on a bag — it comes down to cost per gram and how much your dog actually eats each day.
Most pet owners compare dog food brands by bag price alone, which is misleading. A larger, cheaper bag can actually cost more per day than a premium formula if your dog needs a bigger daily serving size.
Our Pet Food Cost Per Day Calculator does the math for you. Enter your bag weight, price, and daily serving size for up to three brands, and instantly see your true daily, weekly, and monthly feeding costs side by side.
Whether you’re budgeting for one pet or several, this tool gives you a clear, accurate breakdown — so you can make smarter, cost-conscious decisions about your pet’s nutrition without any guesswork.
How It Works
Enter the brand name, bag weight (kg or lbs), bag price, and daily serving size (grams or oz) for up to three dog or cat food brands. Select your currency and number of pets being fed.
The calculator instantly converts all weights to grams and computes the cost per gram for each brand by dividing the bag price by the total weight in grams.
Your daily feeding cost per pet is calculated by multiplying cost per gram by the daily serving size, then scaling by the number of pets in your household. Weekly, monthly, and annual costs are derived automatically.
Results appear in a side-by-side comparison table with a colour-coded Best Value badge on the most affordable brand, a bar chart of monthly costs, and a savings callout showing exactly how much you save per year by choosing the cheapest option.
