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 rather than 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.
