How to Use This Calculator
- Enter the infant's current Age in months (0–24) and Weight in kg from the most recent clinical measurement.
- Enter the number of Feedings per Day — newborns typically feed 8–12 times per 24 hours; older infants feed 4–6 times.
- Review the Daily Volume in mL and Per Feeding amount in mL to guide formula preparation.
- Check the Calories per Day output against age-appropriate targets (typically 100–120 kcal/kg/day for infants).
- Note the Recommended Formula type — standard 20 kcal/oz for healthy term infants; specialty formulas may be needed for specific conditions.
How the result changes with Weight
| Weight | Daily Volume | Per Feeding |

| 8.3 | 1,178 mL | 196 mL |
| 14 | 1,985 mL | 331 mL |
| 18 | 2,552 mL | 425 mL |
