What Is the Formula to Calculate Your Food Cost Percentage?
Understanding the formula to calculate your food cost percentage is fundamental for any successful restaurant operation. At its core, the food cost percentage represents the portion of your total sales revenue that is spent on food ingredients. The standard formula used by industry professionals is: Food Cost Percentage = (Cost of Goods Sold / Total Food Sales) x 100. To find your Cost of Goods Sold (COGS), you must track your inventory levels meticulously using the formula: (Beginning Inventory + New Purchases – Ending Inventory). This metric serves as a vital sign for your business health. A high percentage suggests you might be overpaying for supplies, experiencing high levels of waste, or pricing your menu items too low. Conversely, a percentage that is too low might indicate you are compromising on quality or portion sizes, which could alienate your customer base in the long run. By mastering this calculation, restaurant owners can make data-driven decisions that directly impact their bottom line and operational efficiency.
How the Calculator Works
This calculator simplifies a complex accounting process into four easy steps. First, it takes your Beginning Inventory, which is the dollar value of the stock you had on hand at the start of a specific period (usually a week or a month). Second, it adds your Purchases, which includes all the food and beverage stock you bought during that same period. Third, it subtracts your Ending Inventory, the value of the items left on your shelves at the end of the period. This calculation gives us the Cost of Goods Sold (COGS). Finally, the calculator divides that COGS by your Total Food Sales for that period and multiplies by 100 to yield a percentage. This process allows you to see exactly how much of every dollar earned is being reinvested back into raw product.

Example Calculations
Example 1: The Small Bistro
A local bistro starts the week with $2,000 in inventory. They buy $800 more in fresh produce and meat. By Sunday night, they have $1,800 left. Their total food sales were $4,000. COGS = ($2,000 + $800 – $1,800) = $1,000. Food Cost % = ($1,000 / $4,000) = 25%. This is an excellent, highly profitable margin.
Example 2: The Large Steakhouse
A steakhouse has a beginning inventory of $15,000. They purchase $10,000 in high-end cuts of beef. They end the month with $12,000 in stock. Their sales were $25,000. COGS = ($15,000 + $10,000 – $12,000) = $13,000. Food Cost % = ($13,000 / $25,000) = 52%. This is very high and indicates the need for a price increase or a change in portion sizes.
Common Use Cases
This calculator is essential for weekly financial audits, monthly P&L reviews, and menu redesigns. It is also used by consultants when evaluating a business for sale and by lenders like the U.S. Small Business Administration to assess loan eligibility. Franchisors use it to ensure their franchisees are maintaining corporate standards for efficiency and profitability.

Q: Why is my percentage higher than my target?
A: Common reasons include rising supplier prices, unrecorded waste, theft, or inconsistent portion sizes by kitchen staff.
Q: Does "Beginning Inventory" include paper goods?
A: Usually, food cost is separated from "Supplies." However, some restaurants include disposables if they are a significant expense. For accuracy, it is best to keep them separate.
