Food Cost Calculator and How to Calculate Food Cost Percentage

Short answer: food cost percentage = (beginning inventory + purchases − ending inventory) ÷ food sales × 100. If you started the month with $8,200 of food, bought $26,400, ended with $7,900 and sold $84,000 of food, your food cost is 31.8%. Most US restaurants land near 30%: the National Restaurant Association’s fiscal 2024 medians were 30.0% for full-service and 31.3% for limited-service.

The calculator below does three jobs: your food cost percentage for a week or month, the plate cost of a single dish (with trim and yield built in), and the menu price you need to hit a target. The example numbers are filled in so you can see how it works. Swap in your own.

How to calculate food cost percentage

To calculate food cost percentage, work out the cost of the food you actually used, then divide it by food sales for the same period. Food used is beginning inventory plus purchases minus ending inventory. Multiply by 100 to get a percentage.

Here’s the process step by step:

1. Count your beginning inventory. This is the dollar value of all food on hand at the start of the period. Usually it’s last period’s ending count, so you only count once per period.
2. Add every food purchase in the period. Use invoices, not payments. Subtract credits for returns and shorts.
3. Count your ending inventory on the last day, at the same time of day as last time. Value it at what you paid.
4. Calculate food used: $8,200 + $26,400 − $7,900 = $26,700.
5. Divide by food sales: $26,700 ÷ $84,000 = 0.318, or 31.8%.

On $84,000 of monthly food sales, every point of food cost is worth $840 a month, or about $10,000 a year. That’s why it’s worth counting carefully.

Weekly counts catch problems while you can still fix them. Monthly counts are fine for a stable menu. Whatever you pick, keep the same day and time so the numbers are comparable.

How to calculate plate cost for one dish

Plate cost is the cost of every ingredient on one plate. For each ingredient, divide the case price by the case size to get a unit cost, multiply by the amount you use, then divide by the yield percentage. Add up the ingredients. The food cost percentage for that dish is plate cost ÷ menu price × 100.

Here’s the grilled chicken sandwich from the calculator, using example case prices:

Ingredient	Case price	Case size	Used per plate	Yield	Cost
Chicken breast	$52.00	160 oz	6 oz	100%	$1.95
Brioche bun	$9.60	24 count	1	100%	$0.40
Romaine	$28.00	384 oz	1 oz	67%	$0.11
Tomato	$24.00	400 oz	1.5 oz	90%	$0.10
Cheddar slice	$22.00	160 slices	1	100%	$0.14
Aioli	$14.00	128 oz	1 oz	100%	$0.11
Fries	$36.00	480 oz	5 oz	100%	$0.38
Plate cost					$3.18

Example prices for illustration. Use your own invoices; prices vary by region, supplier and week.

At a $12 menu price, the sandwich runs a 26.5% food cost and leaves $8.82 of contribution, meaning the money left after the ingredients to pay for labor, rent and profit.

Two things are easy to miss:

• The small stuff adds up. Sauce, garnish, the pickle, the fry oil, the to-go container. Put them in the recipe card or your plate cost will read 2 or 3 points low.
• Portions drift. A 6-ounce breast that’s really 7 ounces adds $0.33 a plate. At 60 sandwiches a day, that’s about $7,100 a year on one item.

Food cost percentage per dish is useful, but contribution in dollars pays the bills. A $28 steak at a 38% food cost leaves $17.36. A $14 pasta at a 22% food cost leaves $10.92. The steak looks worse as a percentage and earns more per plate. Our guide to restaurant profit margins shows how that contribution turns into profit after labor and rent.

Why yield changes your real food cost

Yield percentage is the share of what you buy that ends up usable after trimming, peeling or cooking. To get the true cost per usable pound, divide the as-purchased price by the yield. Broccoli bought at $2.00 a pound with a 47% florets-only yield really costs $4.26 per usable pound.

The yields above come from the US Foods produce yield guide, which is based on USDA Agriculture Handbook 102. Your own yields will differ with grade, size, season and how your cooks trim. The fastest way to know is to test: weigh a case before and after prep a few times and use your average.

Yield matters most on proteins and on produce with big trim losses. If your recipe cards assume 100% yield on broccoli, your plate cost for that side is about half of the real number.

What should a restaurant’s food cost be?

Most US restaurants should aim for a food cost of roughly 28% to 32% of sales. The National Restaurant Association’s fiscal 2024 medians were 30.0% for full-service and 31.3% for limited-service. Concepts built on expensive proteins run higher: Texas Roadhouse’s food and beverage costs came to 35.1% of sales in 2025.

There’s no single right number, because food cost trades off against labor. A steakhouse can carry a 35% food cost because a steak needs less kitchen labor than a scratch-made pasta. A from-scratch concept with cheap ingredients might run 26% food cost and a heavy labor line.

The better target is prime cost: food and beverage cost plus labor. At the NRA medians, full-service prime cost was 66.5% of sales (30.0% food and beverage plus 36.5% labor). If you keep prime cost in the low 60s, a food cost a couple of points above average can work fine.

To set your own food cost target:

1. Start from your pre-tax profit goal, say 6%.
2. Subtract your fixed and semi-fixed costs (occupancy, operating costs, overhead) from what’s left.
3. Split the remainder between food and labor based on how your kitchen runs.

If you’re still planning the restaurant, put this math into your restaurant business plan before you sign a lease.

Ideal vs actual food cost: finding the gap

Ideal food cost (also called theoretical food cost) is what your food cost should be if every plate matched its recipe card and nothing was wasted. Actual food cost is what the inventory count says you really used. The gap between them is your variance, and it’s where waste, over-portioning, theft and invoice errors hide.

To find your ideal food cost:

1. Pull item sales for the period from your POS.
2. Multiply each item’s quantity sold by its plate cost.
3. Add it up and divide by food sales.

Say your ideal food cost is 28.5% and your actual is 31.8%. That 3.3-point variance on $84,000 of food sales is $2,772 of food a month that left the building without being sold at full price.

A common rule of thumb is to dig in once the gap goes over 1 to 2 points. When it does, check in this order:

• Portioning on your top 10 sellers. Weigh them for a week.
• Waste. Log what goes in the trash, with a reason.
• Comps and staff meals. Ring them in so they show up in the POS.
• Invoices. Check delivered weights against invoiced weights and look for price creep.
• Theft. Usually the last explanation, and the hardest to prove.

What 2026 food prices mean for your food cost

USDA’s October 2026 forecast has retail beef and veal prices rising 8.7% in 2026 and fresh vegetables 5.8%, while eggs fall 29.3% and dairy is roughly flat. Restaurant menu prices are forecast to rise 3.5%, faster than grocery prices at 2.3%. If beef drives your menu, your food cost is probably climbing even if nothing else changed.

These are retail price forecasts, not your supplier’s prices, but they point the same way. What to do with them:

• Beef-heavy menus: re-cost burgers and steaks now, not at your next menu reprint. Consider blended burgers, a smaller steak cut, or moving a beef dish down the menu.
• Produce-heavy menus: check yields and waste first. A 5.8% price rise on produce you throw a third of away hurts more than it looks.
• Brunch and baking: falling egg prices give you some relief. Use it to hold prices instead of passing the savings back.
• Pricing: with menu prices already rising faster than grocery prices, guests notice. Small, targeted increases on high-contribution items land better than across-the-board jumps.

How to lower food cost without cutting quality

The fastest way to lower food cost is to stop the loss you’re already paying for: over-portioning, waste and invoice errors. Those fixes don’t touch the guest experience. Price increases and recipe changes come after.

1. Standardize portions. Scales on the line, portion scoops, pre-portioned proteins. Start with your five highest-volume items.
2. Cost every recipe, including the extras. Update plate costs when supplier prices change, not once a year.
3. Check every delivery. Weigh proteins, count cases, reject short or damaged product, and get the credit on the invoice.
4. Order from par levels, not habit. Over-ordering turns into spoilage. Set par levels by day of week.
5. Rotate stock first in, first out. Label and date everything.
6. Track waste. A simple waste log on a clipboard often shows that most of the waste comes from two or three items.
7. Cross-use ingredients. Fewer unique SKUs means less spoilage and better buying power.
8. Reprice by contribution. Raise prices on popular, high-contribution items first, in small steps.

Someone has to own this weekly. In most restaurants that’s the kitchen manager or the GM; our guide to restaurant manager duties covers how to build it into the role. If food cost is rising while sales are falling, fix waste first: lower sales mean more product ages out on the shelf.

Food cost mistakes that skew the number

Most “bad” restaurant food cost numbers are measurement problems before they’re kitchen problems. Check these before you change a single recipe:

• Dividing by total sales instead of food sales. If your bar sales go in the denominator, your food cost looks better than it is. Track beverage cost separately.
• Counting at different times. Counting Monday morning one month and Sunday night the next can swing the number by a point or more.
• Missing invoices. One late invoice makes this period look great and next period look terrible.
• Ignoring credits. Returns and shorts that never get credited are money you paid for nothing.
• Not ringing in comps and staff meals. The food leaves inventory but never shows up as a sale.
• Valuing inventory at old prices. Use current costs, or your ending inventory will be off.
• Forgetting transfers. Food moved to the bar for garnishes, or between locations, needs to move on paper too.

FAQ

What is the formula for food cost percentage?

Food cost percentage = (beginning inventory + purchases − ending inventory) ÷ food sales × 100. For example, ($8,200 + $26,400 − $7,900) ÷ $84,000 × 100 = 31.8%.

What is a good food cost percentage for a restaurant?

A good food cost percentage for most US restaurants is about 28% to 32% of sales. The NRA’s fiscal 2024 medians were 30.0% for full-service and 31.3% for limited-service. Steakhouses and seafood concepts often run higher and make up for it with lower labor or higher dollar contribution.

How do you calculate food cost per plate?

For each ingredient, divide the case price by the case size, multiply by the amount used, and divide by the yield percentage. Add up every ingredient, including sauces and garnish. Divide the total by the menu price to get that dish’s food cost percentage.

How do you set a menu price from food cost?

Divide the plate cost by your target food cost percentage. A $4.25 plate at a 30% target needs a price of $14.17, which you might round to $14.99. Then check the dollar contribution as well as the percentage.

Should food cost include beverages?

No. Track food cost and beverage cost separately, each against its own sales. Drinks usually carry a much lower cost percentage than food, so mixing them hides problems in the kitchen.

How often should I calculate food cost?

Weekly if you can, monthly at minimum. Weekly counts catch waste, portioning and invoice problems while you can still fix them. Always count on the same day and at the same time.

What is the difference between food cost and prime cost?

Food cost is what you spend on ingredients. Prime cost is food and beverage cost plus labor. At the NRA’s fiscal 2024 medians, full-service prime cost was about 66.5% of sales, so labor is usually the bigger half.
