When a vendor product is selected for a food item, the food item will be assigned a cost per serving (which can be viewed on the Vendor Product Selection screen). This article explains how the cost per serving is calculated for a food item with a density value.
- If Food Item with a Density Value Has a Defined Portion Size
- If Food Item with a Density Value Has No Defined Portion Size
If Food Item with a Density Value Has a Defined Portion Size
A food item with a density value is typically measured by volume. If a food item with a density value has a defined portion size, then the calculation is as follows:
- The first calculation is to determine the price per millilitre by dividing the pack price by the total millilitres of the assigned pack size (total millilitres = stock units multiplied by stock unit measure in millilitres).
- The second calculation is to multiply the price per millilitre by the portion size measure of the food item to determine the cost per serving, but without the density applied.
- The third calculation is to apply the density by dividing the cost per serving by the density of the food item.
Pack Price / (Stock Units in the Assigned Pack Size x Stock Unit Measure in Millilitres) = Price per Millilitre | Multiply by Portion Size Measure of the Food Item (second screenshot below). | Divide by Density of Food Item (third screenshot below) | Cost per Serving with Density Applied | ||
$10.51 / (30 x 200 ml = 6000 total ml) = 0.0017516666666667 | 0.00175166666666672 x 125 grams = 0.2189583333333333 | 0.2189583333333333 / 1.048218 = 0.2088862558488151 | $0.21 for 1 Each (125 grams) | ||

If Food Item with a Density Value Has No Defined Portion Size
A food item with a density value it typically measured by volume. If a food item with a density value has no defined portion size. then the system uses a default portion size of 100 grams. As such, the calculations are as follows:
- The first calculation is to determine the price per millilitre by dividing the pack price by the total millilitres of the assigned pack size (total millilitres = stock units multiplied by stock unit measure in millilitres).
- The second calculation is to multiply the price per millilitres by 100 grams to determine the cost per serving, but without the density applied.
- The third calculation is to apply the density by dividing the cost per serving by the density of the food item.
Pack Price / (Stock Units in the Assigned Pack Size x Stock Unit Measure in Millilitres) = Price per Millilitre | Multiply by 100 grams | Divide by Density of Food (second screenshot below) | Cost per Serving with Density Applied | ||
$40.49 / (6 x 2840 ml = 17040 total ml) = 0.0023761737089202 | 0.0023761737089202 x 100 grams = 0.2376173708920188 | 0.2376173708920188 / 1.054981 = 0.2252337917858415 | $0.23 for 100 grams | ||
