Dog Food Portion & Cost Calculator
Calculate your dog's daily calorie needs, food portions, and monthly feeding costs by weight, activity level, and food type. Free and science-based.
Dog Food Portion Formula (RER-Based)
Uses the Resting Energy Requirement (RER) formula from veterinary nutrition science, adjusted for activity level and life stage.
Activity multipliers range from 1.2 (sedentary) to 2.5 (working/athletic dogs). Puppies need approximately 2× adult calories per unit of body weight.
