What is the cooked yield on a 20
lb inside round?
Finding the portion cost of roast beef.
If we start with an inside round that weighs 20 lbs
and trim off 4 lbs of fat and have a cooking loss of 4 lbs the net
weight will be 12 lbs. By dividing the gross weight by the net weight,
we will have the percent of yield, which is 60%. If the inside rounds
cost is $2.50 lb and we add the $1 labor, the total is $3.50. We then
divide $3.50 by the 60% yield and we will have a finished cost of $5.83
lb. To figure the portion cost we find the price per ounce and multiply
it by the portion size. This would also be a good test to see if it is
more cost efficient to buy a precooked inside round.
