Homemade dog food: how to estimate calories without guessing
Counting calories in homemade food is the easy part — the same math any feeding chart uses. The hard part is making sure the recipe is actually balanced. That second part needs a vet nutritionist, not a calculator.
What this page is
A calorie estimator for dogs eating homemade meals — daily kcal target, ingredient kcal-per-100g for portioning. Not a complete-diet calculator. Not a recipe. Not a substitute for a Board Certified Veterinary Nutritionist (DACVIM-Nutrition) when you're feeding homemade as a complete daily diet. Find a board-certified veterinary nutritionist via ACVIM.
A homemade dog meal's calorie math runs the exact same way kibble math does — the dog's daily kcal target is set by body weight and life stage, not by what's on the plate. The work is translating that target into a portion size when each ingredient has its own kcal-per-100g and the recipe varies week to week. The math is below; what no calculator can do is turn a calorie-correct meal into a nutrient-complete one.

Hi, I'm the PawsCalculator assistant. I answer questions about pet calorie, weight, age, and feeding math — and how the calculators on this site work. I'm not a veterinarian and I can't give personal veterinary advice. For weight-loss programs, prescription diets, or age-related illness, talk to a licensed veterinarian.
The daily target — same math as kibble
The formula veterinary nutrition references publish: resting energy requirement is 70 × (body weight in kg)0.75, and you multiply that by a life-stage factor for the daily target. Neutered adult, 1.6×; intact adult, 1.8×; weight loss, 1.0×; growth, 2-3×. A 25-pound (11.3 kg) neutered adult lands at roughly 685 kcal/day. The target doesn't care whether the calories come from chicken-and-rice or a cup of kibble — it cares about total kcal in.
Pull the daily kcal target from the dog calorie calculator on this site or from any veterinary-grade calculator (the Pet Nutrition Alliance one is the institutional reference). Then portion the homemade meal to that target. The portion math is what the rest of this guide is.
Ingredient kcal-per-100g — the rough table
Public-domain numbers from USDA FoodData Central, given for typical cuts. Ranges reflect natural variation between cuts, fat trim, and skin-on/skin-off. Use the midpoint as a starting estimate; if you're cooking the same recipe weekly, weigh the cooked batch once and divide by daily target to lock in the actual portion for your specific ingredients.
- Chicken breast (cooked, no skin): ~165 kcal/100g
- Chicken thigh (cooked, no skin): ~210 kcal/100g
- Ground beef, 90/10 lean (cooked): ~215 kcal/100g
- Ground beef, 70/30 (cooked): ~285 kcal/100g
- Turkey breast (cooked, no skin): ~155 kcal/100g
- White rice (cooked): ~130 kcal/100g
- Brown rice (cooked): ~125 kcal/100g
- Sweet potato (baked, no skin): ~90 kcal/100g
- Pumpkin (canned, plain): ~30 kcal/100g
- Green beans (cooked): ~35 kcal/100g
- Carrot (cooked): ~35 kcal/100g
- Egg (cooked, whole): ~155 kcal/100g (about 70 kcal each large egg)
One opinion worth holding: don't trust per-cup or per-piece estimates from blog posts. Weigh ingredients in grams. A cup of cooked rice from one batch can be 40 percent denser than a cup from another (water content varies wildly), and the difference is invisible to the eye. A kitchen scale is twelve dollars and pays back daily.
When to stop calculating and call a board-certified nutritionist
The calorie calculator does its job and stops at total daily kcal. What it can't answer: is the meal complete? Is the calcium-to-phosphorus ratio right? Is there enough taurine for the breed? Is the omega-3 to omega-6 ratio sustainable? Are micronutrient levels adequate at the calorie level the dog actually needs? These are the questions a Board Certified Veterinary Nutritionist answers — and they're the questions an unguided homemade diet most often gets wrong.
Tufts University's clinical nutrition service puts the cleanest framing on it: if your dog has multiple medical issues, complicated conditions, has trouble maintaining ideal weight, or you're feeding a non-traditional diet, ask your primary-care vet whether a consult with a Board Certified Veterinary Nutritionist would help. That's the decision rule. Calorie calculators are valuable for portioning a formulated recipe; they're the wrong tool for building one.
Where to start the search: the ACVIM Diplomate directory (American College of Veterinary Internal Medicine, Nutrition specialty) and Balance IT, the homemade-recipe formulation tool developed by a Board Certified Veterinary Nutritionist that pairs with vet consultation. Both are appropriate next steps when the homemade meal is the dog's primary diet.
Questions worth asking
Is a homemade calorie calculator enough to feed my dog safely?
For calories, yes — the math is the same as the kibble math. For nutrients (essential amino acids, fatty acids, calcium-to-phosphorus ratio, trace minerals, vitamins), no. A calorie calculator can tell you the dog ate 800 kcal yesterday and that's the right amount; it can't tell you the meal had a calcium deficiency or was protein-light on methionine. Adult dogs on homemade diets without nutrition oversight commonly drift into one or two specific deficiencies within a few months. Calorie tracking is the easy half; complete-diet formulation is the residency-trained half.
Where do the kcal-per-100g numbers come from?
USDA FoodData Central is the public-domain reference for raw and cooked ingredient calories. The numbers in this guide are USDA values for typical cuts. Your specific ingredient will vary — a trimmed lean chicken breast runs lower than a skin-on thigh, and a 90/10 ground beef runs lower than 70/30. Use the published numbers as starting points; if you're cooking the same recipe weekly, weigh the finished meal once and divide by your dog's daily target to lock in the actual portion size for your batch.
Should I include the cooking weight or the raw weight?
Whichever you're tracking consistently. Most owners weigh meat raw and add cooked vegetables and rice; that's fine if the recipe is consistent. Raw meat loses water during cooking and becomes more calorie-dense per gram cooked, but the total calories of the cut don't change much — water leaves, kcal stays. The kitchen-scale routine that's easiest to repeat (raw or cooked, just one) gets you closer to the right answer than the conceptually cleanest one you skip half the time.
Can I substitute ingredients freely if the calories match?
On the calorie side, yes. On the nutrient side, no — and that's the danger of homemade. Swapping chicken breast for the same calories of beef changes amino-acid balance, fatty-acid profile, mineral density, and vitamin content. A complete homemade recipe formulated by a board-certified nutritionist specifies ingredients and proportions for nutrient reasons, not just calorie reasons. If you're using this calculator to portion-control a recipe a Board Certified Veterinary Nutritionist already formulated, substitutions are off-recipe. If you're free-styling without a formulation, that's the conversation to have before this calculator becomes useful.
Why doesn't this site publish homemade dog food recipes?
Because publishing a recipe without it being formulated by a Board Certified Veterinary Nutritionist for a specific dog's medical context would create a complete-diet claim this site can't honestly back. Calorie estimation is calculator-shaped math. Recipe formulation is medical work — it factors in the dog's age, body shape, kidney function, allergies, joint status, and the proportions and supplements that turn a meal into a complete diet. The site's lane is the math; the recipes belong with the people who can be held accountable for them.
