Formula & Mathematical Methodology

Standard Mathematical Formula
Daily Food (cups) = Daily MER (kcal) ÷ Food Caloric Density (kcal/cup)

Step-by-Step Calculation Example

Example: 50 lb Dog on Standard Kibble (375 kcal/cup)

A 50 lb active adult dog fed twice daily with a 30 lb bag costing $65.

  1. 50 lbs (22.68 kg) MER = 70 × (22.68)^0.75 × 1.6 = ~792 kcal/day
  2. Daily Cups = 792 ÷ 375 kcal/cup = 2.11 cups/day
  3. Per meal (2 feedings) = 1.05 cups/meal (~110 grams/meal)
  4. Monthly consumption = ~20 lbs/month = ~$43.30/month
Final Output: 2.1 Cups/Day (~1.05 cups per meal) — ~$43/Month

Key Assumptions

  • Standard dry kibble density averages approximately 100 to 110 grams per measuring cup.
