Pet Calorie Needs Calculator

How to calculate pet calorie needs?

Calculation begins with the Resting Energy Requirement (RER), which is then adjusted by a multiplier based on life stage and activity level.

Formula: RER = 70 × (weight in kg)^0.75

Using the Pet Calorie calculator: an example

Example: A neutered adult dog weighing 10kg with a typical activity level.

Step-by-step calculation:

• Calculate RER: 70 × (10)^0.75 = 394 kcal
• Apply maintenance multiplier (1.6 for neutered adult)
• Total Daily Calories: 394 × 1.6 = 630 kcal

Yes, the total daily calories include everything your pet eats. Treats should make up no more than 10% of total intake.
