Baby Formula Cost Calculator

What formula produces the monthly cost?

The tool multiplies feeds per day by an age-based volume per feed to get daily millilitres, then × 30 for a month. It divides that by the prepared volume of the chosen unit to get units per month, and multiplies by your price per unit. With the defaults (2 months, 8 feeds, 900 g can at $25) that is 8 × 105 = 840 ml a day, 25,200 ml a month, 4.0 cans and $100.00. Annual cost is the monthly cost × 12.

Where does the volume per feed come from?

It comes from a fixed table inside the tool: 75 ml for babies up to 1 month, 105 ml up to 3 months, 135 ml up to 6 months and 210 ml for 7 months and older. These are the tool’s built-in planning values for pricing, not feeding recommendations. Your baby’s actual intake can differ, so follow your pediatrician’s guidance on how much to feed.

Does the Formula Type setting change the result?

No. The formula type selector is not used in the calculation. The unit size selector is what sets the prepared yield: 2,800 ml for the 400 g can, 6,300 ml for the 900 g can, 946 ml for the ready-to-feed carton and 770 ml for the 385 ml concentrate (the tool doubles concentrate when mixed). Pick the unit size that matches the product you buy.

What if my product makes a different amount than the tool assumes?

The yields are fixed numbers, so the tool cannot read your label. A workable adjustment is to scale the price you enter by the tool’s yield divided by your product’s real yield. If your 900 g can makes less than 6,300 ml, enter a proportionally higher price. Check the preparation instructions on the container for the true yield.

How are feeds per day treated?

You choose the number. An entry of 0, which is also what a cleared box becomes, falls back to 8, and anything else below 1 is raised to 1. The tool does not lower the count as the baby ages, but the volume per feed jumps to 210 ml from month 7, so with the default 8 feeds a 7-month-old comes out at 1,680 ml a day. Enter the number of formula feeds you actually give.

Why is the annual cost exactly 12 times the monthly cost?

Months are modelled as 30 days, so a year is 360 days of formula. Price changes, growth in volume as the baby gets older, and a switch of formula type partway through the year are not modelled. For a more realistic year, run the calculator once per age stage and add the results.

Does it account for breastfeeding or mixed feeding?

No. The calculator prices only the formula feeds you tell it about. To model mixed feeding, reduce feeds per day to the number of formula feeds. It does not estimate any savings from breastfeeding.

How are fractional or unusual ages handled?

Age is read in months and any value of 1 or less uses the 75 ml band; a cleared box or a negative entry counts as 0. Fractional months are allowed, so 3.5 months falls into the 135 ml band. There is no upper limit on age, and every age from 7 months onward uses 210 ml.
