What is Restaurant Cost of Goods Sold?

Restaurant COGS is the direct cost of ingredients. It includes all items sold. This metric excludes overhead. Rent or labor are not included. It focuses solely on menu item creation costs.
Know your COGS. This helps price dishes correctly. It highlights ways to reduce food waste. A typical restaurant food cost percentage is 25-35%. High COGS shrinks profit margins fast.

The Essential COGS Formula

Calculate COGS with a simple formula. It accounts for starting inventory, new purchases, and ending inventory. The formula is: Beginning Inventory + Purchases – Ending Inventory = COGS.
Apply this formula over a specific accounting period. This could be a week, month, or quarter. Consistent reporting periods ensure accurate comparisons.

Calculating Your Beginning Inventory

Beginning inventory is the total value of sellable ingredients at the period’s start. Conduct a physical inventory count. List every item and its current cost. Sum these values for your total beginning inventory.
For example, if your period starts January 1st, your beginning inventory is the value of all food and beverage items on hand then. A POS system like Lavu tracks inventory movements. It provides a strong starting point for accurate counts.

Tracking All Purchases

This component includes all food and beverage items bought during the period. Keep detailed records of all invoices. Sum these costs for your total purchases.
Include delivery fees or other direct ingredient acquisition costs. If you buy $5,000 in produce, meat, and dairy in a month, that is your total purchases for that period.

Determining Your Ending Inventory

Ending inventory is the total value of sellable ingredients remaining at the period’s end. Perform another physical count. This process mirrors your beginning inventory count. One period’s ending inventory becomes the next period’s beginning inventory.
Accurate ending inventory directly impacts your COGS. Overcounted ending inventory artificially lowers COGS. Undercounted ending inventory inflates it.

Understanding Inventory Variance and Spoilage

Real inventory rarely matches calculations. Variance comes from spoilage, waste, theft, and portion control. Track these losses carefully. Do not include spoiled items in ending inventory value.
Marty, Lavu’s AI analytics, flags unusual inventory discrepancies. It identifies issues before they drain profit. Reducing waste directly improves COGS.

Analyzing COGS for Profitability

Once you have COGS, divide it by total sales revenue for the same period. This provides your food cost percentage. Aim for 25-35%. If higher, examine purchasing, portioning, and waste.
For instance, if your monthly sales are $50,000 and your COGS is $15,000, your food cost percentage is 30%. Review this percentage regularly. Adjust menu prices or seek better supplier deals. Lavu provides sales data to pair with your COGS for easy analysis.
