How It Works
Calculation Principle
Different dog foods have wildly different calorie densities — from 250 kcal/cup for some weight-management formulas to 500+ kcal/cup for high-performance foods. This tool calculates how many cups of each food your dog needs to meet their daily calorie requirement. It also estimates daily cost based on bag price, helping you compare true feeding costs, not just bag prices.
How to Use
Enter your dog's daily calorie needs (from the Calorie Calculator). Add foods by brand name, kcal per cup, protein percentage, and bag price. Click Compare Foods to see cups-per-day, cost-per-day, and how each food compares to your target portion. Save comparisons to review later.
Practical Tips
Do not trust the feeding guide on the bag — it is designed to sell more food, not keep your dog lean. A food with higher protein and fewer fillers often requires smaller portions, making expensive bags last longer. Check the guaranteed analysis for crude protein and fat percentages. If a food costs $90 but lasts 2 months, it may be cheaper per day than a $45 bag that lasts 3 weeks.
