Total cups = 30 × 4 = 120 cups. Daily need = 2 cups. Days per bag = 120 / 2 = 60. Daily cost = $50 / 60 = $0.83. Monthly = $0.83 × 30 = $25.00.

Total cups = 12 × 4 = 48 cups. Daily need = 0.5 cups. Days per bag = 48 / 0.5 = 96 days. Daily cost = $35 / 96 = $0.36. Monthly = $0.36 × 30 = $10.94.
Monthly dog food costs vary by dog size and food quality. Small dogs (under 20 lbs) average $25-40/month, medium dogs (20-60 lbs) average $40-70/month, and large dogs (60+ lbs) average $60-100/month. Premium and prescription foods can cost significantly more.
Daily feeding amounts depend on dog size: small dogs (up to 20 lbs) need about 1 cup/day, medium dogs (20-60 lbs) need about 2 cups/day, and large dogs (60+ lbs) need about 3-4 cups/day. Always check the feeding guide on your specific food bag as calorie density varies.
Premium dog food often contains higher quality proteins, fewer fillers, and more nutrients per cup. While the per-bag cost is higher, the cost per serving may be similar because dogs often eat less of calorie-dense premium food. Quality food can also reduce veterinary costs long-term.
Divide the bag price by total cups in the bag. Total cups = bag weight (lbs) × cups per pound (usually 3.5-4.5, check the bag). For example, a 30-lb bag at $50 with 4 cups/lb = 120 total cups = $0.42 per cup.
Annual cat food costs typically range from $200-500 for dry food. Cats eat about 1/3 to 1/2 cup of dry food per day. Wet food is more expensive, averaging $1-3 per can. A combination of wet and dry food might cost $500-800 per year.
