The only way I can see to do a comparison of cost per 100 calories would be to first know how many cups are in X lbs of food. I know that JD eats about 5 lbs of food per week because that's how long a bag lasts. So I could figure it out based on 3 cups per day times 7 days equals about 21 cups per bag. Then I could multiply the calories per cup by 21 to get the total calories in the bag. Then I could divide the total calories by the price of the bag. I would actually be willing to do that with the orijen formulas that JD eats.
But I'm not willing to buy a bag of every food out there (or even any food out there, lol) and measure them out cup by cup to find out how many cups each one contains. And you'd need that number to determine the cost per 100 calories, I think.
Or am I not doing the right calculations? can you think of an easier way to do it?
So I did the math. Calculus wasn't my strong suit but I did well enough in basic arithmetic but still please check this out. A mistake is easy enough to make. But I think this is about right since one bag does last about a month,etc.
A bag of Acana Wild Prairie is currently $59.99 at doggie food.com. I get 2 at a time so there is free shipping.
Each bag contains 13.5 kg =13,500 grams.
Every 115 grams (a 250ml cup) contains 425 calories. Divide that by 4.25=27 gms. So every 27 grams contains 100 calories.
Every bag contains 500 of these 100 calorie portions ( 3500/27).
So each 100 calories costs 12 cents. ($59.99/500) That is the only true comparison. Not pounds or gms.
That said my doodles consume 4 cups per day total. That said the food costs about $2.04 for the kibble alone.
Even if the cheapest kibble cost half as much, and had the same number of calories per cup, which it doesn't,I'd only save $1.00 a day. Generally cheaper kibble has fewer calories per cup and you need to feed more.
I don't know where to find out how many kgs are in a bag of Orijen. Is it on the website?
Then I guess I have to figure out how to convert kgs to grams, because there are 120 gms in a cup of Orijen, according to the bag.
I also don't buy the larger bags, so I will also have to research the cheapest price for the largest bag (29.7 lbs.)
