Food Cost Calculator
A food cost calculator shows what your ingredients cost as a percentage of the price you charge. Enter an item's ingredient cost and menu price for a single dish, or your beginning inventory, purchases, ending inventory and sales for a whole period - and it returns your food cost percentage instantly.

Food cost formula (item and period)
There are two ways to measure food cost, and the calculator does both. For a single item, divide the ingredient cost by the menu price. For a whole period (a week or month), use your inventory movement and sales. Try each formula live below - change any number and the percentage updates.
Food cost % = ingredient cost ÷ menu price × 100
Food cost % = (beginning + purchases − ending) ÷ sales × 100
Worked example: weekly inventory
Say you start the week with $8,000 of stock, buy $12,000 more, and count $7,500 left at the end - so you used $12,500 of food. Against $40,000 of food sales that's a 31.3% food cost. Edit the numbers below and watch the percentage and the bar move against the common 28-35% rule-of-thumb range.
What drives food cost up
When your percentage climbs, it's usually one of a handful of causes. Tap each to see what to check.
Supplier price rises
Ingredient prices move constantly. If a key item jumps, your food cost rises even though nothing in your kitchen changed. Re-cost your top-selling dishes whenever a major ingredient's price shifts, and compare suppliers.
Portion creep
Servings quietly grow over time when portions aren't controlled. An extra ounce of protein on every plate multiplies across hundreds of covers. Use scales, portion scoops and spec sheets so every plate matches the cost you calculated.
Waste, trim and spoilage
Over-prep, poor rotation and spoiled stock all become food you paid for but never sold. Track waste, order to par levels, and rotate first-in-first-out to keep it down.
Yield loss
Raw ingredients shrink through trimming and cooking. If you cost a dish on raw weight but serve less, your real cost is higher. Factor yield percentage into your recipe costing.
Theft and unrecorded comps
Staff meals, comps and shrinkage that aren't recorded show up as a higher food cost with no matching sales. Log comps and staff meals so your numbers reconcile.
Next step: price the menu
Knowing your food cost is only half the job - the other half is pricing so it lands in your target range. Once you know a dish's plate cost, work backwards from a target food cost percentage to a menu price. For example, a $4.20 plate at a 30% target should sell for $14.00 ($4.20 ÷ 0.30). The menu price calculator does this for you, including .99 and 50¢ rounding.

Frequently asked questions
How can I calculate the cost of food online?
Use the calculator at the top of this page. For a single dish, enter the ingredient cost and the menu price; for a period, enter your beginning inventory, purchases, ending inventory and food sales. It returns your food cost percentage instantly, with no sign-up. You can also try the live formula tools in the sections above.
Is there a free food cost calculator for Excel?
You can build one in Excel with the same formulas: for an item, ingredient cost ÷ menu price; for a period, (beginning + purchases − ending) ÷ sales. This page does it without a spreadsheet, updates live as you type, and gives you a shareable result link, which is quicker for day-to-day checks.
How do I calculate the price per meal?
Add up the cost of every ingredient in one serving - protein, sides, sauce, garnish and any packaging - to get the plate cost. To turn that into a price, divide by your target food cost percentage: a $5 plate at 30% is $16.67. The recipe cost and menu price calculators handle both steps.
How can I calculate my food cost?
Pick a period, count your stock at the start and end, and note what you bought and what you sold. Food cost % = (beginning + purchases − ending) ÷ sales × 100. The worked-example tool above lets you plug in your own "food used" and sales to see the result immediately.
Is a 32.8% food cost acceptable?
For many full-service restaurants, 32.8% sits comfortably inside the common 28-35% rule-of-thumb range, so it's often fine. But "acceptable" depends on your concept, labour costs and menu - a high-volume quick-service model may target lower. Track the trend rather than a single number, and compare it with your own targets.
How to calculate the cost of a food item?
List every ingredient in the item and multiply each by the amount used at its unit price, then add them up. Factor in yield loss from trimming and cooking. That total is your plate cost. Divide it by the menu price to get the item's food cost percentage.
What is the best app for calculating food costs?
The best tool is the one you'll actually use consistently. A free, no-login web calculator like this one is enough for costing dishes and checking your weekly percentage. Larger operations may add inventory software that syncs with suppliers and POS, but the underlying formula is identical.
What is the best free food cost calculator app?
A good free option runs in your browser, needs no account, and shows both the item and period methods with the formula visible so you can trust the result. This calculator does all of that, works on a phone in the kitchen, and lets you share a result link with a partner or manager.
