Homemade Dog & Cat Food Calculator

Record ingredients and amounts to estimate food calories and macro grams. Then see what still needs professional verification: the exact recipe and supplement dose, nutrient amounts, and suitability for your pet. This calculator cannot determine whether a diet is complete or balanced.

Examples illustrate food totals; they are not formulated feeding recipes. No supplement dose is suggested. Enter only the amount specified for the exact product in your formulated recipe, and keep the product label for your vet.

Preparation notes to confirm with your vet
  1. Follow the cooking method in your formulated recipe. Raw animal products can carry pathogens even when a product claims complete nutrition.
  2. Never add onion, garlic, chives, leeks, grapes/raisins, or xylitol — they're toxic. Skip added salt and seasoning.
  3. Cook grains and starchy veg fully so they're digestible; steam or lightly cook vegetables.
  4. Use the exact supplement product, amount, and preparation instructions in the formulated recipe. Do not substitute products or adjust doses using this tool.
  5. Confirm portions and storage with your veterinarian and recipe provider. The energy estimate above does not establish a safe daily diet.
  6. Discuss food transitions with your vet, and report changes in appetite, weight, or stool.

How to use it

  1. 1 Enter your pet's weight and life stage for an estimated daily energy comparison.
  2. 2 Add ingredient weights, or load a food example to explore the arithmetic. Examples are not formulated feeding recipes.
  3. 3 Read approximate food calories and macro grams. Supplement composition is not included in these totals.
  4. 4 Bring the exact recipe, supplement labels and amounts, and the unverified questions to your veterinarian or veterinary nutritionist.

Why this matters

Calories and macro grams do not show whether all essential nutrients are present in suitable amounts. This tool has no complete nutrient analysis, product-specific supplement data, or professional formulation validation. Adding an ingredient cannot clear any nutrition question. A daily homemade diet needs an exact formulated recipe, followed with its specified products, amounts, and preparation instructions.

Frequently asked questions

Can this calculator confirm a complete and balanced diet?

No. It estimates food totals only. Calcium/phosphorus, vitamins and minerals, amino acids, fatty acids, supplement dose, and life-stage suitability remain unverified for every recipe.

Does adding a supplement confirm the diet is balanced?

No. A generic supplement entry has no product analysis or validated dose. Use the exact product and amount specified in a professionally formulated recipe; this calculator cannot choose or check the dose.

What does the daily energy comparison mean?

It divides estimated batch food calories by estimated daily energy needs. It does not tell you how long the batch is safe to feed as a complete daily diet. Your veterinarian should confirm the portion and recipe.

What should I bring for a recipe review?

Bring all ingredient weights, cooking instructions, supplement product labels and actual amounts, plus your pet’s age, weight, health history, and other foods or treats. AAHA recommends consultation with a board-certified veterinary nutritionist for home-prepared diets.
