How to Find Food Cost Percentage

The formula itself is short divide the cost of ingredients by the selling price, then multiply by 100.

Take a chicken sandwich. Chicken, bun, sauce, lettuce, pickles altogether $3.50. It sells for $14. Divide 3.50 by 14. Multiply by 100. The answer is 25%.

That percentage is really just a snapshot. It shows how much of every dollar from that sale goes straight back out to cover ingredients. A dish sitting at 20% leaves far more room for profit than one sitting at 40%, even if both sell for the same price.

Getting an accurate number takes some upkeep, though. Supplier prices shift sometimes more than owners expect, so pulling costs from a few months back tends to throw the whole calculation off. Recipes need actual measurements too. A "handful of cheese" means something different depending on who's working that shift, and that inconsistency shows up directly in the math.

Restaurants serious about controlling costs don't calculate this once and move on. They run the numbers across the full menu and check back periodically, since both prices and popularity change with the seasons. That habit is usually what separates a restaurant that catches a slow price creep early from one that only notices after several months of shrinking margins.
