Food Cost Percentage Calculator

Food cost percentage is one of three numbers that determines whether a restaurant survives. The other two are labor cost and prime cost. This calculator handles the first one.

The formula is straightforward: beginning inventory plus purchases minus ending inventory equals your Cost of Goods Sold (COGS). Divide COGS by total food sales and multiply by 100. The hard part is knowing what that number should be for your type of restaurant, and what it costs you when you are off target.

What Your Food Cost Percentage Should Be

Industry benchmarks vary by restaurant format. A quick-service operator running 33% food cost has a problem. A fine dining chef running 38% may be right on target. Use the table below to calibrate your number against the correct peer group.

The COGS Formula Explained

Many operators track food cost by dividing this week's purchases by this week's sales. That method produces a number, but it is not accurate. The correct formula accounts for inventory movement:

COGS = Beginning Inventory + Purchases - Ending Inventory

Here is why the inventory adjustment matters. If you ordered $50,000 in food this month but your ending inventory is $8,000 higher than your beginning inventory, you only consumed $42,000 worth of food. Dividing $50,000 by your sales overstates your food cost by the full $8,000 swing. Over a busy holiday month when you stock up, that error can make your food cost look 3-5% higher than it really is.

The reverse is also true. If you ran down inventory aggressively before a slow week, your COGS using purchases alone understates the cost of what you actually served.

What Happens When You Are Above Target

High food cost percentage typically traces to one or more of four causes:

1. Over-portioning. Staff is plating more than the recipe specifies. Each dish costs more than the menu price was designed to cover.
2. Spoilage and waste. Product is ordered or prepped in quantities that exceed what sells before expiration. This is often a forecasting and prep discipline problem.
3. Theft. Internal shrinkage is a real cost center in kitchens and bars. It is typically caught by comparing theoretical food cost (based on recipes and sales mix) against actual food cost (based on inventory).
4. Supplier pricing and commodity inflation. PPI for All Foods stood 35% above its February 2020 reading as of April 2026, per NRA economic indicators. Many operators are running higher food cost percentages than their pre-pandemic baseline with no change in operational discipline. If your cost has risen, the question is whether your menu prices kept pace.

The Prime Cost Connection

Food cost tells you whether your kitchen is controlling ingredient spend. Prime cost tells you whether the whole operation is viable. Prime Cost = COGS + Total Labor Cost. Industry target is 55-65% of total revenue. If your food cost is 32% and your labor cost is 35%, your prime cost is 67%: above the healthy zone. You may need to look at scheduling efficiency, not just the walk-in.
