What is a Pet Food & Calorie Calculator?

A pet food calculator uses your dog or cat's weight, life stage, and activity level to scientifically calculate their Resting Energy Requirement (RER) and Daily Energy Requirement (DER), then converts that into the exact grams of food to serve each day based on your food's calorie density. Built on the internationally recognized veterinary formula (RER = 70 ร— weight^0.75), it helps you maintain your pet's healthy weight and prevent obesity.

Common Use Cases

๐Ÿถ
Dog Weight Management
Calculate an overweight dog's daily calorie target and determine how much to reduce portions for a safe, effective weight-loss plan.
๐Ÿฑ
Kitten Nutritional Support
Kittens need significantly more calories than adult cats. Get the right portion size for each growth stage to support healthy development.
๐Ÿฅ
Pre-Vet Visit Prep
Calculate your pet's daily calorie intake before a vet appointment to make nutritional consultations more productive.
๐Ÿ›’
Monthly Food Budget Planning
Use the daily portion recommendation to forecast monthly food consumption and buy the right amount economically.

    Select species (dog/cat), enter weight (kg), choose life stage (puppy to senior), and select activity level (low/normal/high).
  2. 2
    Enter food calorie density
    Input the calorie content (kcal/kg) of the food you currently serve. Find this on the bag's label or the manufacturer's website.
  3. 3
    View recommended portion
    RER, DER, and daily food amount (g) are calculated. Split the total evenly between morning and evening meals.
