How do I calculate food cost percentage for my restaurant?
Food cost percentage measures how much of your food sales revenue goes toward ingredients. It’s one of the most important numbers for restaurant profitability because it directly impacts your margins.
The formula is straightforward: divide your food costs by your food sales and multiply by 100.
For overall restaurant food cost, you first need to calculate your cost of goods sold for a specific period. Take your beginning inventory value, add all food purchases during that period, then subtract your ending inventory value. That gives you the actual cost of food used.
Here’s an example. You start the month with $8,000 in food inventory. During the month you purchase $15,000 in food. At month end, your inventory counts to $7,500. Your cost of goods sold is $8,000 + $15,000 - $7,500 = $15,500. If your food sales for the month were $48,000, your food cost percentage is 32.3%.
For individual menu items, the calculation is simpler. Add up the cost of every ingredient that goes into one serving, then divide by the menu price. A dish with $4.25 in ingredients priced at $16 has a 26.6% food cost.
Most restaurants aim for food cost between 28% and 35%, though this varies by concept. Fast casual typically runs lower while fine dining can run higher since labor costs are proportionally different. Restaurants with significant bar programs often have lower overall food cost because beverage margins offset food costs.
Calculate this metric at least monthly. Weekly is better if you want to catch problems before they become expensive. A sudden jump in food cost percentage usually means one of a few things: waste increased, portion sizes crept up, vendors raised prices, or theft is happening.
Inventory counts need to happen consistently for the numbers to mean anything. If you count inventory on different days or at different times relative to deliveries, your month-over-month comparisons won’t be accurate. Pick a system and stick with it.
If your food cost percentage is too high, start with portion control. Recipes should specify exact measurements and your kitchen staff should follow them. Check vendor invoices against contracted prices. Review your menu to see if certain dishes are simply not profitable at their current price point.
