Yield and Cost of Edible Product

Objective 4

When you complete this objective you will be able to calculate the yield and cost of an Edible Product.

Formula

Yield% = (EP / AP) x 100%

example #1

A striploin weighs 5.2 kg AP and after trimming weights 4.6 kg (EP). Calculate the Yield percentage.

Y% = (EP / AP) x 100%
Y% = (4.6 / 5.2) x 100%
Y% = .885 x 100%
Y% = 88.5%

example #2

The striploin in example #1 costs $11.95 / kg to purchase. What is the cost per kilogram of the trimmed striploin?

There are 2 methods to find this answer:

a) Using the figures for the striploin we have

5.2 kg x $11.95 / kg = $62.14

so the striploin cost us $62.14 to purchase.
The amount of useable striploin is 4.6 kg

$62.14 / 4.6 kg = $13.51 kg EP.

b) We don't want to do a test every time the price changes. Since we know the yield percentage is 88.5%, we can use this.

$11.95 / 88.5% = $13.51 / kg

example #3

We want to serve 85 people steak sandwiches weighing 170 grams each. How much striploin do we need?

a) Calculate the total amount of trimmed striploin (EP weight) required:

85 portions x 170 grams / portion = 14.45 kilograms minimum weight required.

b) the EP weight will be 88.5% of the AP weight (using our yield percentage)

14.45 kg / 88.5% = 16.33 kg
If we have less than 16.33 kg of striploin, we won't have enough
