A free pet food portion calculator to help you feed your dog or cat the right daily amount.
Not sure how much to feed your dog or cat each day? Our free pet food portion calculator uses veterinary RER and MER formulas to give you a personalized daily feeding amount based on your pet’s weight, age, and activity level.
Whether you have a playful puppy, a senior cat, or anything in between, this pet food portion calculator adjusts for species-specific needs so you’re not relying on generic feeding chart guesswork.
Portion sizes aren’t one-size-fits-all. Spayed or neutered pets, senior animals, and less active breeds often need fewer daily calories than the standard feeding guidelines on packaging suggest, which is why a personalized calculation matters.
If your pet has specific medical needs, allergies, or is on a prescription diet, always check with your veterinarian before making changes to their feeding routine. Results are meant as a helpful starting point and work best alongside guidance from your veterinarian.
