Pet Calorie Calculator

Daily calorie needs and safe treat limits for dogs and cats.

This free pet calorie calculator works for both dogs and cats — estimating daily calorie needs and a safe daily treat amount in one step.

Dogs and cats should only get about 10% of their daily calories from treats. This calculator helps you estimate a safe amount based on your pet's weight, activity level, and goals.

  • Prevent overfeeding
  • Maintain healthy weight
  • Understand daily calorie needs

Pet Calorie Calculator

Our pet calorie calculator works for both dogs and cats. It uses the veterinary Resting Energy Requirement formula — RER = 70 × (weight in kg)^0.75 — then multiplies by an activity factor and adjusts for your pet's weight goal.

Treats should always stay under 10% of daily calories. Use this calculator to see both your pet's daily calorie target and a safe treat budget.

Dog vs Cat Calorie Needs

Dogs use activity multipliers from 1.2 (low) to 2.0 (active), while cats use 1.0 to 1.4. That's why a 50 lb dog can need 1,100+ kcal while a 10 lb cat needs only ~240 kcal/day.

Safe Treat Guidelines

Convert daily calories to a safe treat number with the dog treat calculator or the cat treat calculator.

How the Calculator Works

  1. You enter your pet's weight in either lbs or kg — for example, a 25 lb dog (≈ 11.3 kg) or a 10 lb cat (≈ 4.5 kg). If you enter lbs, we convert to kilograms using kg = lbs ÷ 2.20462.
  2. We calculate Resting Energy Requirement (RER) using the standard veterinary formula: 70 × (kg)0.75. Example: a 25 lb (11.3 kg) dog → 70 × 11.30.75 ≈ 432 kcal.
  3. We multiply RER by an activity factor (1.2–2.0 for dogs, 1.0–1.4 for cats) and adjust for weight goal (×0.8 to lose, ×1.2 to gain).
  4. 10% of that total gives you a safe daily treat calorie limit.

Frequently Asked Questions

How many treats can I give my dog per day?

Treats should make up no more than 10% of your dog's daily calorie intake. The exact number depends on weight, activity level, and the calories per treat. Use the calculator above for a personalized daily limit.

How many treats can I give my cat per day?

The 10% rule applies to cats too. Most adult cats need 200–300 kcal per day, so only 20–30 kcal should come from treats — typically just a few small pieces.

What is the 10% rule for pet treats?

Veterinarians recommend that treats make up no more than 10% of a pet's daily calories so the rest of the diet stays nutritionally balanced.

How are daily calories for dogs and cats calculated?

You can enter your pet's weight in either lbs or kg. We convert lbs to kilograms (kg = lbs ÷ 2.20462), then calculate Resting Energy Requirement as 70 × (kg)0.75. Example: a 25 lb (≈ 11.3 kg) dog → about 432 kcal RER. We then multiply by an activity factor and adjust for your pet's weight goal.
