If you’ve ever looked at your profit and loss statement and wondered why your food cost looks off, you’re not alone. For many restaurant owners, the numbers that go into a P&L can feel confusing, especially when you see things like Cost of Goods Sold and Cost Of Goods Produced.
Both have to do with what you spend on food and supplies, but understanding a key difference will make your finances a lot clearer. It’s also one of the easiest ways to spot waste, track margins, and take advantage of tax deductions for your restaurant.
How To Calculate Cost Of Goods Sold for Restaurants?
Cost of Goods Sold (COGS) refers to what it costs you to make what you sold. If you sell a burger, COGS is the bun, the beef, the cheese, the lettuce, the fries that come with it, basically everything that went into that order. It’s not about what you bought that week; it’s about what was actually used to make the food your customers ordered.
Here’s how to calculate it:
COGS = Beginning Inventory + Purchases – Ending Inventory
Here’s how it works in practice. Let’s say you started with $10,000 worth of food and supplies, bought $25,000 more, and ended the month with $8,000 still in inventory.
Your COGS calculation would look like this:
10,000 + 25,000 – 8,000 = $27,000
This tells you how much food you actually used to generate sales. Most restaurants aim to keep COGS between 28% and 35% of sales, but it depends on your concept and pricing.
Cost of Goods Sold is what helps you understand whether your menu is priced right, if portions are consistent, and if there’s any waste or theft happening behind the scenes.
What Is the Cost Of Goods Purchased for Restaurants?
Cost of Goods Purchased (COGP) is where a lot of restaurant owners get tripped up.
COGP looks only at what you bought, not what you actually used. If you stocked up on extra wine before a busy season or over-ordered produce that’s still sitting in the cooler, those purchases inflate your costs for the month, even though they haven’t turned into sales yet.
In other words, COGP is just your total purchases. It doesn’t account for the food still on the shelf at the end of the period. That’s why using COGP instead of COGS can make your margins look worse than they really are.
COGS vs COGP: Which Should You Use
You might be wondering if it really matters which one you use. It absolutely does, especially if you want to understand your real profitability.
When you treat everything you buy as an expense right away, your food costs jump all over the place. One month, you might stock up and show a huge loss on paper, and the next month, it might look like you’re making record profits just because you didn’t order much.
Using Cost of Goods Sold smooths that out. It shows the true cost of what you used to generate your sales. That helps you see patterns, manage waste, and plan for seasonal changes.
It also matters for taxes. The IRS expects restaurants to track inventory and report the actual cost of goods sold, not just what you purchased. If you expense all your purchases without accounting for inventory, you could run into compliance issues or miss out on deductions you’re entitled to.
Let’s Look at a Simple Example
Using our earlier example, where you started with $10,000 worth of food and supplies, bought $25,000 more, and ended the month with $8,000 still in inventory. And your restaurant brought in $100,000 in sales this month.
COGS = 10,000 + 25,000 – 8,000 = $27,000
COGS percentage = 27,000 (COGS) ÷ $100,000 (Sales) = 27%
That means it cost you $27,000 to make the food and drinks you sold. Your COGS percentage would be 27%.
If you only looked at your purchases of $25,000, you’d think your costs were lower than they really were, and you’d be making decisions based on the wrong number.

Restaurant COGS in 2026: What Operators Are Actually Seeing
Restaurant cost of goods sold (COGS) has settled into a different baseline in 2026 than the volatile 2022 to 2024 stretch. Center-of-plate proteins remain elevated against pre-2022 norms but have stopped rising at the pace operators got used to. Produce has come down; specialty ingredients are mixed. The result is that 2026 food cost percentages are running 1 to 2 points higher than 2019 for most full-service concepts, and the operators winning are the ones who rebuilt their menu engineering and supply chain discipline rather than waiting for prices to roll back.
How to Calculate Restaurant COGS Correctly
The COGS formula is simple: beginning inventory plus purchases minus ending inventory equals cost of goods sold. The hard part is the inventory count. Most restaurants calculate COGS weekly because food and beverage cost drifts fast enough that monthly reporting catches problems after they’ve cost real money.
The accurate version of the calculation tracks COGS by category, not as one number. Food cost, beer cost, wine cost, liquor cost, and NA beverage cost each behave differently. A single COGS line that combines them hides the actual operating story.
What Restaurant COGS Percentage Should an Operator Target?
The benchmarks below assume each category is calculated against its own category revenue, not against total sales.
- Food cost: 28 to 35 percent of food sales for full-service; 25 to 30 percent for fast-casual; 35 percent and above for steakhouses, sushi, and other protein-heavy concepts
- Beer cost: 18 to 25 percent of beer sales (lower for high-margin craft programs with strong pricing)
- Wine cost: 30 to 38 percent of wine sales; varies meaningfully with wine list strategy
- Liquor cost: 15 to 22 percent of liquor sales; cocktail-program concepts target lower
- NA beverage cost: 8 to 15 percent of NA beverage sales
Operators running outside these ranges should investigate before assuming a problem. A scratch-kitchen concept will have higher food cost than a frozen-product concept and that’s expected. The benchmark is a starting point, not a verdict.
Why Most Restaurants Calculate COGS Wrong
The most common 2026 restaurant COGS mistake is using the invoice-only method (also called “cost of food sold” or “purchases percentage”). That method divides total food purchases by total food sales and calls it food cost. It ignores inventory swings entirely. In a week where the kitchen brings inventory levels down to absorb a big event, invoice-only COGS looks artificially low. In a week where the kitchen builds inventory for a holiday, it looks artificially high.
The accurate method requires an actual inventory count, ideally weekly. The first month of accurate weekly COGS reporting is uncomfortable for most operators because the numbers stop matching what they thought they were. That discomfort is the point.
How to Reduce Restaurant Food Cost Without Losing Quality
Food cost reduction work in 2026 generally falls into four buckets. Menu engineering: looking at the contribution margin of every menu item and re-ordering the menu so high-margin items get more prominence. Portion standardization: re-training the line on plate weights and tightening the smallwares used for portioning. Vendor management: re-bidding key categories annually and consolidating to fewer vendors for volume pricing. And waste tracking: counting what gets thrown out, both prep waste and post-service waste, and using the data to inform purchasing.
None of these are dramatic. Done consistently, they typically pull 100 to 200 basis points of food cost out of a concept over a six- to twelve-month period.
