How this feeding calculator works
We estimate Resting Energy Requirement (RER = 70 x weight in kg^0.75), adjust for life stage and activity, then divide by the calories per cup printed on your food bag to get cup-based portions.
Dog Feeding Calculator
Estimate daily portions in cups by combining your dog's calorie needs with the calories per cup listed on your food label.

Why calories per cup matter
Two cups from different brands can contain wildly different calories. Always read the Guaranteed Analysis or nutritional label so the calculator has an accurate kcal-per-cup value.
How many meals per day?
Most adult dogs thrive on two meals per day, while puppies often do better with three to four smaller servings. Choose the meal count that matches your vet's guidance.
When to adjust portions
Track body condition, appetite, stool quality, and activity. If weight trends up or down, adjust servings gradually and check with your veterinarian before making big changes.
Sample dog feeding chart
Assumes 360 kcal per cup and a normal-activity adult. Adjust cups for higher or lower calorie foods.
| Weight range | Estimated calories | Cups per day |
|---|---|---|
| 5-10 lbs | 220-360 kcal | 0.6-1.0 cups/day |
| 15-25 lbs | 420-650 kcal | 1.2-1.8 cups/day |
| 30-45 lbs | 700-950 kcal | 2.0-2.7 cups/day |
| 50-70 lbs | 1,000-1,300 kcal | 2.8-3.6 cups/day |
| 80-100 lbs | 1,380-1,700 kcal | 3.8-4.7 cups/day |
FAQ
How much should I feed my dog per day?
Start with a calorie estimate based on weight, life stage, and activity, then divide by the calories per cup listed on your food label. Adjust every few weeks based on body condition and vet feedback.
How many cups of dog food should I feed my dog?
Use this calculator to turn calories into cups by entering the kcal per cup from your bag. Higher-calorie foods need fewer cups than lower-calorie diets.
Does activity level affect feeding amount?
Yes. Working and sporting dogs often need 10-20% more calories (and cups) than couch-friendly companions. Choose the activity level that matches your dog's daily output.
How many times a day should a dog eat?
Most adult dogs eat twice daily, puppies may need three to four meals, and seniors sometimes prefer smaller, more frequent portions. Follow your vet's plan and your dog's digestion cues.
Why does dog food calorie density matter?
Calorie density tells you how much energy is packed into a cup. Without it, it's impossible to compare brands or know whether two cups are too much or too little.
Is this better than a dog calorie calculator?
They work together. Use the Dog Calorie Calculator to estimate daily energy needs, then plug that information here to translate calories into cups per meal.
