How the Calculator Works

  1. Convert Weight – Pounds are converted to kilograms for calculations.
  2. RER Calculation – RER = 70 × (Weight in kg)^0.75
  3. Activity Multiplier – Adjusts calories based on activity:
    • Sedentary: 1.2
    • Normal: 1.4
    • Active: 1.6
    • Very Active: 2.0
  4. Life Stage Multiplier – Adjusts for age and growth needs:
    • Puppy/Kitten: Dogs 2.0, Cats 2.5
    • Adult: 1.0
    • Senior: 0.8
    • Pregnant/Nursing: 2.5
  5. Body Condition Multiplier – Adjusts for weight management:
    • Underweight: 1.2
    • Ideal: 1.0
    • Overweight: 0.8
  6. Neutered Multiplier – Spayed/neutered pets: 0.95, intact pets: 1.0
  7. DER Calculation – DER = RER × Activity × Life Stage × Body Condition × Neutered
  8. Food Recommendation – Converts calories to cups and grams using average calories per cup (Dog: 350 kcal, Cat: 300 kcal; 1 cup = 120 g).

Example 1: Adult Dog, Normal Activity

  • Weight: 30 lbs
  • Activity: Normal
  • Life Stage: Adult
  • Body Condition: Ideal
  • Neutered: Yes

Calculation:

  • Weight in kg: 30 × 0.453592 = 13.61 kg
  • RER = 70 × (13.61)^0.75 ≈ 393 kcal/day
  • DER = 393 × 1.4 × 1.0 × 1.0 × 0.95 ≈ 522 kcal/day
  • Food Cups = 522 / 350 ≈ 1.49 cups/day
  • Food Weight = 1.49 × 120 ≈ 179 g/day

Recommendation: Feed 2 meals daily and adjust as needed.

Example 2: Senior Cat, Sedentary

  • Weight: 10 lbs
  • Activity: Sedentary
  • Life Stage: Senior
  • Body Condition: Overweight
  • Neutered: Yes

Calculation:

  • Weight in kg: 10 × 0.453592 = 4.54 kg
  • RER = 70 × (4.54)^0.75 ≈ 146 kcal/day
  • DER = 146 × 1.2 × 0.8 × 0.8 × 0.95 ≈ 106 kcal/day
  • Food Cups = 106 / 300 ≈ 0.35 cups/day
  • Food Weight = 0.35 × 120 ≈ 42 g/day

Recommendation: Feed less and increase exercise to lose weight.

Benefits of Using the Pet Food Calculator
