Use the DER calculator for daily calories

Last updated : 11 juin 2026 ID: HT10027

Estimate energy requirements based on weight, age, activity level, and neutering status.

Note: Calculations follow standard clinical formulas defined by veterinary nutrition boards (NRC/FEDIAF).

Steps to follow:

  1. Open the **Tools** tab and tap **DER Calculator**.
  2. Pick the pet you want to calculate for. The app pulls their latest logged weight.
  3. Specify their physiological status (Intact, Neutered, Puppy, Active Working Dog, etc.) and daily activity level.
  4. The engine outputs the recommended daily kilocalories (kcal) and provides approximate feed weight translations.
Tip: For mixed feeding plans (dry kibble + wet cans), divide the kcal outputs according to your preferred ratio.
