Calculate Cost of Goods Sold
Cost of goods sold, or COGS, represents the direct cost of the food and beverages a restaurant sells. It is one of the most important sections of a restaurant P&L statement because even small increases in ingredient costs can significantly affect profitability.
Restaurant COGS commonly includes items such as -
1. Food ingredients - Meat, produce, dairy, dry goods, sauces, and other ingredients used to prepare menu items.
2. Beverages - Soft drinks, coffee, beer, wine, liquor, and other beverages sold to customers.
3. Other directly consumed products - Depending on the restaurant, this may include certain packaging or consumable items tied directly to sales.
A common way to calculate COGS is -
Beginning Inventory + Purchases - Ending Inventory = Cost of Goods Sold
For example, if a restaurant starts the month with $12,000 in inventory, purchases $28,000 in food and beverages, and ends with $10,000 in inventory, its COGS would be $30,000.
Restaurant owners should also monitor COGS as a percentage of sales -
COGS Percentage = COGS / Net Sales x 100
If COGS rises faster than revenue, it can reduce gross profit. Possible causes include higher supplier prices, food waste, overportioning, theft, inaccurate inventory counts, or poor purchasing practices.
Reviewing COGS regularly helps owners identify cost changes early. Comparing actual food and beverage costs with previous periods, budgets, and menu pricing can also reveal whether adjustments are needed.
Because food and beverage costs are major controllable expenses, understanding COGS helps restaurant owners use their P&L statement to make better purchasing, inventory, portioning, and pricing decisions.
