Dog Food Cost Calculator

The price on the bag tells you almost nothing about what a food actually costs to feed. Enter your dog’s daily calories, the food’s calories per cup, and the bag price and size — this works out your real cost per day, month, and year, and how long each bag lasts.

Quick answer: compare cost per day, not price per bag. A pricier, calorie-dense food can cost less per day because you feed fewer cups. Cost per day = (daily calories ÷ kcal per cup) × (bag price ÷ cups per bag).

1. Daily calories your dog eats (kcal/day)

2. Food’s calories per cup (on the bag)
Labeled “Calorie Content (kcal ME/cup)”
3. Bag price ($)
4. Bag size (lb)

Fill in all four fields to see your daily, monthly, and yearly feeding cost.

How the calculation works

The math is simple once you have four numbers:

  • Daily calories— how much your dog actually eats per day. If you don’t know it, the calorie calculator gives a vet-grade figure from weight, life stage, and activity.
  • Calories per cup— printed on every US dog food bag as “Calorie Content (kcal ME/cup),” a labeling requirement overseen by AAFCO. Most dry foods are 350–400; premium calorie-dense formulas reach 450+; weight-management foods drop to ~300.
  • Bag price and size — to get the price per cup. A pound of dry kibble is about 4 cups, so a 30 lb bag holds roughly 120 cups. Density varies, so weigh a cup of your specific food if you want a precise number.

cost/day = (daily kcal ÷ kcal per cup) × (bag price ÷ (bag lb × 4))

Then monthly is cost/day × 30.4 and yearly is cost/day × 365.

Why “cost per day” beats “price per bag”

A $70 bag of premium food can be cheaper to feed than a $40 bag of budget food. Premium formulas are often more calorie-dense, so a 50 lb dog might eat 2 cups a day instead of 3. Fewer cups means the expensive bag lasts longer, which closes most of the price gap. Per AKC nutrition guidance, any food meeting AAFCO’s “complete and balanced” standard is nutritionally adequate — so judge value by daily cost, not the sticker.

What this doesn’t include

This is dry-food cost only. Treats, dental chews, supplements, fresh or toppers, and the occasional prescription diet all add up — treats alone should stay under about 10% of daily calories. Wet food and fresh-cooked subscriptions cost several times more per calorie than kibble, so price those separately.
