There is a calculator sitting on a lot of our product pages now, under a heading that reads how much to feed, and what it costs per day. Most people scroll straight past it. It answers the question we get asked more than any other at the counter, so it is worth two minutes of your time.
It has three boxes. Your dog's weight in pounds. The bag size, from a dropdown. And what you paid in dollars.
Fill those in and it gives you back three things: how much to feed per day, how long that bag will last, and what the food costs you per day.
The third box is the one that confuses people, and the page explains why. Some brands have pricing policies that stop us showing a price on the page at all. The note under the calculator says it plainly: add the item to your cart to see the price, then type it in above and the calculator does the rest. It is an extra click and it is not our idea, but the arithmetic still works once you have the number.
Here is why the output matters more than it sounds.
Cost per day is the only number that lets you compare two foods honestly. A bag price tells you almost nothing on its own, because bags are different sizes, foods are different densities, and a dog eats calories rather than ounces. Two bags at the same price can last wildly different amounts of time with the same dog. We have watched people choose the cheaper bag and spend more over a year, and the bag price is what fooled them. If you want to work through it on something you already feed, bring the bag to 1288 Highway 33 and we will run it with you.
A few things worth knowing so the number you get back is actually true.
Use your dog's real weight, not the one from two years ago. The calculator is built off the manufacturer's feeding chart, and those charts are banded by weight, so a guess of sixty on a seventy pound dog throws the whole thing off.
Pick the bag size you actually buy, not the biggest one in the list. The per day cost changes with the size.
And know which way you are feeding. On a topper product like a Meal Mixer, there is a feeding chart for using it as a complete meal and a separate one for using it as a topper, and the two amounts are not close. The calculator reflects the charts on that page. If your real-world use is somewhere between the two, your actual cost sits between the two numbers as well.
One honest limitation. The calculator cannot know that you also give three biscuits a day, or that your dog gets the last spoonful of yogurt. It costs out the food on that page, nothing else. That is still a far better answer than guessing, it just is not your whole pet food budget.
If you want to put two different foods head to head rather than cost out one, we built a second calculator for that. It lives in Cost Per Bag Is the Wrong Number and it will tell you which of two bags is actually cheaper to feed, and by how much over a year.
Our opinion on all this, for what it is worth. We would rather you ran the numbers and chose a cheaper food than bought an expensive one you quietly resent every month. Feeding something good consistently beats feeding something excellent for six weeks and then switching back because the math got uncomfortable.
Go run it on whatever you are feeding right now. Most people are surprised, and roughly half the time they are surprised in the good direction.
