How this works
Cost per gram = bag price ÷ bag weight in grams. Daily cost = grams fed × cost per gram.
Cups are approximated at 110 g per cup, the average for premium kibble. Density varies by brand; weighing portions in grams is the most accurate method.

How to lower your dog food cost without losing quality
- Feed by calorie target, not bag chart. Most pet dogs are overfed by 20–40%. Calorie-correct portions save money and extend lifespan via lean body condition.
- Use autoship discounts. Chewy and Amazon both offer 5–10% off recurring orders. Stacked with first-order promos, monthly cost drops 10–30%.
- Size up if you can store it. The same brand at 30 lb is often 15–25% cheaper per pound than the 4 lb size. Just keep kibble in an airtight container and use within 6 weeks of opening.
- Don't trade down to a brand without AAFCO feeding trial substantiation. A short-term saving on a poorly QA'd brand can cost thousands in vet bills.
Frequently asked
How much does dog food cost per month?

How long does a 30 lb bag of dog food last a 50 lb dog?
A 30 lb bag of premium kibble fed at about 2.5 cups per day (~275 grams) to a 50 lb adult dog lasts roughly 49 days, or about 1.6 months. Smaller dogs make a bag last longer; larger or more active dogs go through it faster.
How much should I budget for a dog food per year?
Annual dog food cost for a typical 50 lb adult dog is $480–1,080 for dry kibble (mass-market to premium), $1,800–3,000+ for fresh or freeze-dried subscriptions, and $960–1,800 for prescription therapeutic diets. Treats, supplements, and dental chews typically add $200–400 per year.
Is more expensive dog food actually better?
Not automatically. Price reflects ingredient sourcing, manufacturing, and marketing — not always nutrient delivery. Veterinary nutrition guidance prioritizes AAFCO feeding trial substantiation, WSAVA manufacturer-quality criteria (full-time nutritionist, owned plants, batch QA), and life-stage adequacy over premium-tier pricing.
How can I lower my dog food cost without compromising quality?
Three highest-impact tactics: (1) feed by calorie count, not bag charts — most pet dogs are overfed by 20–40%, (2) use Chewy/Amazon autoship discounts (5–10% off), (3) consider larger bag sizes if storage and freshness allow (the per-pound cost drops 15–25%). Avoid trading down to a brand without AAFCO feeding trial substantiation.
Note: Calculations assume kibble at ~110 g per cup, an average for premium dry food. Density varies by brand and shape; for the most accurate budget, weigh your portions in grams. Price ranges reflect typical US 2026 retail and exclude treats, supplements, or veterinary diets.
