Baby Formula Cost Calculator
Work out how much infant formula your baby drinks and what it costs per day, per month and per can.
How it works
oz/day ≈ min(weight × 2.5, 32) · scoops/day = oz/day ÷ oz-per-scoop · cans/month = scoops/day × 30.4 ÷ scoops-per-can
Infant formula intake tracks body weight — a common rule of thumb is about 2.5 oz of prepared formula per pound per day, leveling off near 32 oz as solids begin. Converting ounces to scoops (via the label ratio) and then to cans is what turns intake into a real grocery number. Because each can is a fixed number of scoops, a heavier baby empties a can faster, so cost per month climbs even at the same can price.
Worked example
A 12 lb baby needs about 30 oz a day. At 2 oz per scoop that is 15 scoops; a 90-scoop can lasts 6 days. A $30 can then costs $5 a day and about $152 a month.

Frequently asked questions
How much formula does a baby drink per day?
A widely used guideline is 2.5 oz of prepared formula per pound of body weight per day, up to roughly 32 oz total. A 10 lb baby is around 25 oz; intake plateaus once solids start near 6 months.
How do I find scoops per can?
The can states the total number of scoops (often 80–100) and the mixing ratio, usually one level scoop per 2 oz of water. Divide the can’s net weight guidance or read the "makes X oz" line to confirm.
Is store-brand formula safe?
In the US all infant formula must meet the same FDA nutrient standards, so store brands are nutritionally comparable to name brands and usually much cheaper per ounce. Always match your baby’s type (standard, sensitive, etc.).
