Daily oz = 10 lbs × 2.5 = 25 oz. Scoops = 25 / 2 = 12.5. Powder used = 12.5 × 0.31 = 3.88 oz/day. Days per can = 12.5 / 3.88 = 3.22. Monthly cost = ($30 / 3.22) × 30 = $279.50.

Daily oz = 16 × 2.5 = 40 oz. At 5 feeds/day = 8 oz per feed. Scoops = 40 / 2 = 20. Powder = 20 × 0.31 = 6.2 oz/day. Days per can = 12.5 / 6.2 = 2.02. Cost = ($30 / 2.02) × 30 = $445.54.
The standard guideline is 2.5 oz of formula per pound of body weight per day. A 10 lb baby needs about 25 oz daily divided into 6-8 feedings. Newborns start with 1-2 oz per feed and gradually increase to 6-8 oz by 6 months.
| Age | Oz per Feed | Feeds/Day | Daily Total |
|---|---|---|---|
| Newborn | 1-2 oz | 8 | 8-16 oz |
| 1 month | 3-4 oz | 7 | 21-28 oz |
| 2-3 months | 4-5 oz | 6 | 24-30 oz |
| 4-5 months | 5-6 oz | 5 | 25-30 oz |
| 6-12 months | 6-8 oz | 4 | 24-32 oz |
Baby formula costs $100-$300 per month depending on the brand. Standard powdered formula averages $1,200-$1,800 per year. Generic brands cost 30-50% less than name brands with virtually identical nutrition and FDA-regulated ingredients.
| Type | Monthly Cost | Annual Cost | Cost per Oz |
|---|---|---|---|
| Generic Powder | $80-$120 | $960-$1,440 | $0.08-$0.12 |
| Name Brand | $120-$200 | $1,440-$2,400 | $0.12-$0.20 |
| Organic | $150-$250 | $1,800-$3,000 | $0.15-$0.25 |
| Ready-to-Feed | $200-$400 | $2,400-$4,800 | $0.25-$0.40 |
Most formula brands use 1 scoop per 2 oz of water. One scoop is typically 8.7-8.8 grams (about 0.31 oz). Always follow the specific instructions on your formula container, as ratios vary by brand. Never add extra water to stretch formula.
A standard 12.5 oz can of powdered formula makes approximately 90 oz of prepared formula and lasts 3-5 days for an average baby. A newborn uses about one can per week, while a 6-month-old may go through one can every 3 days.
Increase formula by 1 oz per feeding when your baby consistently finishes every bottle and seems hungry afterward. Watch for hunger cues like rooting, fist sucking, and fussiness after feeding. Most babies naturally increase intake until about 32 oz/day maximum.
