Cost What You Serve: Mastering Edible Portion Costing
When you buy a 10 lb raw brisket, you aren't actually serving 10 lbs of meat to your guests. This is the critical distinction between As Purchased (AP) cost, the price you pay for the raw ingredient, and Edible Portion (EP) cost, the price of what is actually served after trimming and cooking
For caterers, mistaking these two is a primary reason why "profitable-looking" menus often quietly underperform; the quantity you purchase is almost never the quantity that goes into the final dish.
The "quiet inflation" of your costs happens through Percent Yield, which is the usable weight of an ingredient divided by its raw weight
Large proteins like brisket experience significant weight loss from fat trimming and cooking shrinkage
If your 10 lb brisket has a 60% yield, you are left with only 6 lbs of servable meat
To find your true cost, you must use the formula: EP Cost = AP Cost / Yield %.
If you paid $5.00/lb for that raw brisket (AP), your real cost is actually $8.33 per served pound ($5.00 / 0.60)—a massive increase that will sink your margins if you price based on the raw weight.
Ignoring these yield losses makes your ingredients look cheaper than they are, leading to a "theoretical cost" that doesn't match reality.
To fully protect your profit, you must also account for the "Q Factor," an additional 5-10% buffer for hidden costs like salt, oil, and overproduction waste.
Mastering these calculations is essential for caterers to bridge the gap between estimated and actual food costs, ensuring every event generates a clear margin after all preparation and cooking losses are accounted for.
