Show the math
Once you know the daily calorie target, divide it by the food's energy density to get how much to serve, then split across meals:
cups/day = daily kcal ÷ kcal per cup
grams/day = daily kcal ÷ (kcal per kg ÷ 1000)
The energy figures (kcal/cup and kcal/kg) are printed on the food's packaging. Use the daily calorie need from a calorie calculator or your vet.
Treats count toward the daily total. Everything is calculated in your browser.
What this does
A pet food portion calculator turns a daily calorie target into cups and grams of food per day and per meal, using the energy figures on the bag.
How to use it
- Enter the daily calorie target.
- Enter the food’s kcal per cup or kg.
- Set meals per day.
- Read the amount per meal.
How it works
Divide the daily calorie need by the food’s kcal per cup or per kg, then split across meals. Treats count toward the daily total.
daily amount = calorie need ÷ food energy density
Understanding your result
The portion is only as accurate as the energy figure on the bag, so check the kcal per cup or kilogram for your exact food. Remember treats count toward the daily total, and split the amount across meals. Adjust over a few weeks based on your pets body condition, not the chart alone.
Example
500 kcal/day on 350 kcal/cup food is about 1.4 cups.
