Profit Margin Calculator for Restaurants
Restaurants are the clearest example of a business where gross margin looks healthy and the bottom line does not. A dish with a 70% gross margin sounds excellent until labour, rent, utilities and waste are taken out — which is why the industry works to a different set of numbers than most retailers.
Enter your plate cost and menu price to get the margin and the food cost percentage that operators actually manage to. Then use the benchmarks below to sanity-check both, and read the prime cost section — it is the figure that determines whether a restaurant survives, and it is not gross margin.
Direct cost only — materials, goods, delivery.
Add volume to see total profit rather than per-unit.
Gross profit margin
73.75%
$11.80 profit on each unit sold.
- Profit per unit
- $11.80
- Selling price
- $16.00
- Equivalent markup
- 280.95%
Markup divides profit by cost, so it always reads higher than margin.
This is gross margin — it excludes rent, salaries, marketing and tax. A healthy gross margin can still leave a net loss if overheads are high.

Food cost percentage is gross margin inverted
Restaurant operators talk in food cost percentage rather than margin, but they are two views of the same number: food cost % = 100 − gross margin %. A dish costing $4.20 sold at $16 has a 26% food cost and a 74% gross margin.
Targets vary by service style and by category within the same menu. The figures below are the bands most operators work within.
| Category | Target cost % | Implied gross margin |
|---|---|---|
| Food, full service | 28% to 35% | 65% to 72% |
| Food, quick service | 25% to 32% | 68% to 75% |
| Beer, draft | 18% to 24% | 76% to 82% |
| Spirits / cocktails | 18% to 24% | 76% to 82% |
| Wine by the glass | 28% to 35% | 65% to 72% |
| Non-alcoholic drinks | 10% to 18% | 82% to 90% |
Prime cost is the number that matters
Prime cost is cost of goods plus total labour, expressed as a share of revenue. It captures the two largest and most controllable costs in one figure, and it is the standard operators are judged by.
The widely used benchmark is prime cost at or below 60% for full service and 65% for quick service. Above that, the remaining 35% to 40% has to cover rent, utilities, insurance, marketing, repairs, debt service and profit — and it usually cannot.
| Prime cost | What it means |
|---|---|
| Under 55% | Strong. Investigate whether quality or portions are being cut |
| 55% to 60% | Healthy for full service |
| 60% to 65% | Tight; workable for quick service, marginal for full service |
| 65% to 70% | Losing money in most rent structures |
| Over 70% | Structurally unprofitable — pricing or staffing must change |
Where restaurant margin actually leaks
- Waste and spoilage. A 3% food-waste rate on a 30% food cost adds roughly a point of cost straight off the bottom line.
- Portion drift. Recipes costed at 4 oz and plated at 5 oz raise your food cost by 25% on that item, invisibly.
- Comps and staff meals not tracked. These belong in your cost of goods, not written off as marketing.
- Menu mix. Your margin is the weighted average of what people actually order, not the average of what is on the menu. A high-margin dish nobody chooses does not help.
- Supplier price drift. Costing a menu once a year in an inflationary market means running the second half of that year on numbers that are no longer true. Recost quarterly.
- Delivery platform commission. Orders at 20% to 30% commission need separate pricing — the same menu price produces a completely different margin through a marketplace.
Frequently asked questions
- What is a good profit margin for a restaurant?
- Gross margin on food is typically 65% to 72%, but net margin — after labour, rent and everything else — averages only about 3% to 9%. A restaurant clearing 10% net is doing well. Judge yourself on prime cost and net margin rather than gross margin, because gross margin alone hides the two biggest costs.
- How do I calculate food cost percentage?
- Divide the cost of the ingredients by the menu price and multiply by 100. A plate costing $4.20 sold at $16 is a 26% food cost. For a period rather than a dish, use (opening inventory + purchases − closing inventory) ÷ food sales, which captures waste and theft that per-plate costing misses.
- How should I price a new menu item?
- Start from your target food cost: divide the plate cost by your target as a decimal. A $4.20 plate at a 28% target gives $15. Then adjust for the menu context — what similar dishes cost, what the item does for perceived value, and whether it can carry a premium. Never price purely on a multiplier without checking it against the market.
- What is prime cost and why does it matter more than margin?
- Prime cost is cost of goods plus total labour as a share of revenue. It matters more because food cost and labour trade off against each other — buying prepared items lowers labour and raises food cost, and prepping in house does the reverse. Prime cost is the figure that cannot be gamed by shifting cost between the two.
- Should delivery orders be priced differently?
- Yes. A 25% platform commission on a dish with a 28% food cost leaves very little, and packaging adds more. Many operators run higher menu prices on delivery platforms to preserve margin. Model each channel separately rather than assuming one price works everywhere.
