Food Cost Percentage: Formula and What's Good
Food cost percentage is what your ingredients cost as a share of the revenue they generate: food cost ÷ food sales × 100. A dish costing $4.20 sold at $14 has a 30% food cost. Most full-service restaurants aim for roughly 28-35% as a rule of thumb, but the right target depends on your concept.

The formula
There are two versions of the same idea. For a single item: ingredient cost ÷ menu price × 100. A $4.20 plate sold at $14 is 30%.
For a whole period (a week or month), use inventory: (beginning inventory + purchases − ending inventory) ÷ food sales × 100. The top of that fraction is the food you actually used; the bottom is what you sold it for. If you started with $8,000 of stock, bought $12,000, and ended with $7,500, you used $12,500. Against $40,000 of food sales that's 31.25%.
The item version tells you whether a dish is priced right; the period version tells you what's really happening across the kitchen, including waste and portioning. Use both - the calculator does each.
Actual vs ideal food cost
Your ideal (or theoretical) food cost is what your recipes say you should spend: cost every dish, multiply by how many you sold, and compare with sales. Your actual food cost comes from inventory - what you really used.
The gap between them is the story. If your ideal is 29% but your actual is 34%, that five-point difference is leaking somewhere: over-portioning, waste, spoilage, comps, or theft. A dish-by-dish ideal cost is what makes the actual number diagnosable rather than just alarming.
Track both regularly. A small, stable gap is normal; a widening one is a signal to check portioning and ordering before it eats your profit. Costing recipes and plates is how you build the ideal figure to measure against.
What is a good food cost percentage (by concept)
There's no single "good" number - it depends on your format and your other costs. As rules of thumb, not rules:
- Fine dining: often 28-35%; high ingredient quality offset by higher prices.
- Casual full-service: commonly ~28-32%.
- Pizza / pasta concepts: can run lower, sometimes 25-30%, on cheap-to-plate staples.
- Steakhouses / seafood: often higher, as premium proteins push cost up.
What matters is that food, labour and occupancy together leave room for profit. A 33% food cost is fine if your labour and rent are controlled; the same number can be a problem if they aren't.
The 30/30/10-style rules and their limits
You'll often hear a "30/30/10" guide: roughly 30% of revenue to food, 30% to labour, 10% to occupancy, with the rest covering other costs and profit. It's a useful sanity check for a new concept.
But it's a starting benchmark, not a law. A quick-service spot might run food higher and labour lower; a bar-led venue leans on drink margins so food can run higher; a rural location may have low rent but higher delivery costs. Chasing a textbook 30% food cost while ignoring labour or rent can lead you to the wrong decisions.
Use the ratios to spot something obviously out of line, then manage the actual dollars. Your own P&L, not a memorised rule, is the real target.
7 ways to lower food cost
- Re-cost regularly so price rises don't quietly erode margins.
- Portion with tools - scales, scoops, spec sheets - to stop portion creep.
- Track and cut waste with prep-to-par ordering and first-in-first-out rotation.
- Use trim and offcuts in specials, stocks and staff meals instead of the bin.
- Negotiate and compare suppliers on your highest-spend items.
- Engineer the menu - promote high-margin dishes, fix or drop low-margin ones.
- Reprice or re-spec dishes whose food cost has drifted above target.
Small gains stack: a couple of points off food cost often falls straight to the bottom line.
Frequently asked questions
Is the 32.8% food cost acceptable?
For many full-service restaurants, 32.8% sits inside the common 28-35% rule-of-thumb range, so it's often acceptable. Whether it's right for you depends on your concept, labour and rent - a high-volume quick-service model may target lower. Watch the trend rather than a single figure, and compare it against your own P&L targets.
Is 30% a typical food cost?
Yes - 30% is a widely used benchmark for full-service restaurants, and many operators price dishes to a 30% target. It's a rule of thumb, not a requirement: quick-service can run lower and premium-protein concepts higher. What matters is that food, labour and occupancy together leave room for profit.
How do you calculate cost percentage?
Divide the cost by the revenue it produces and multiply by 100. For food, that's food cost ÷ food sales × 100. For one dish it's ingredient cost ÷ menu price × 100. A $4.20 plate at $14 is 30%. The calculator does both the item and the period versions.
How do you calculate the cost of food?
For a period, use inventory: beginning inventory + purchases − ending inventory = the food you used. For a dish, add up the cost of every ingredient in one serving. Both give you the "cost" figure you then compare against sales or menu price to get a percentage.
What is a normal food cost percentage?
Most full-service restaurants land somewhere around 28-35%, but "normal" varies by concept - quick service can be lower, premium-protein venues higher. Rather than aim for a universal number, set a target that leaves enough after food, labour and rent for profit, and track your actual figure against it.
Is 20% food cost good?
A 20% food cost is very low and means high gross margin on food - common for drinks, coffee or dough-based items, less so for full plates. It's "good" for profit but can signal small portions or premium pricing that may affect value perception. Balance margin against what guests feel they're getting.
What does a 33% food cost percentage imply?
It means a third of your food revenue goes to buying the food, leaving two-thirds as gross profit to cover labour, rent, other costs and profit. It's within the typical range for full-service dining. Whether it's healthy depends on your other costs - 33% works if labour and occupancy are controlled.
How to calculate the percentage of food?
Take the food cost, divide it by food sales (or, for one dish, by the menu price), and multiply by 100. That's your food cost percentage. Enter your figures into the calculator and it returns the percentage instantly for either a single item or a whole period.
