How to calculate food cost percentage
Food cost percentage tells you how much of every sales dollar is being spent on the food itself. It's one of the first numbers any restaurant operator checks, because it moves fast when portions, waste, or supplier prices shift.
What counts as COGS?
Cost of goods sold is the cost of the food and beverage inventory actually used during the period — opening inventory plus purchases, minus closing inventory. It excludes labor, rent, and other overhead.
What's a healthy food cost percentage?
Most full-service restaurants target 28-35%. Fine dining can run higher due to premium ingredients and lower volume, while quick-service and pizza concepts often sit lower, around 25-30%, because of simpler menus and higher throughput. The right target depends on your concept, portion sizes, and menu pricing.
Why your food cost % might be off
- Portion sizes drifting from the recipe spec
- Waste and spoilage not being tracked
- Supplier price increases not reflected in menu prices
- Comps, staff meals, or promotions not excluded from sales
Food cost benchmarks by restaurant type
| Concept | Typical Food Cost % |
|---|---|
| Pizza / bakery | 24–28% |
| Quick-service / fast casual | 25–30% |
| Full-service / casual dining | 28–35% |
| Steakhouse / seafood | 32–38% |
| Fine dining | 33–40% |
Remember: a higher food cost isn't automatically bad. A steakhouse at 36% food cost with a high average check can be far more profitable per cover than a cafe at 26%. What matters is whether the number fits your concept and is stable over time.
How to interpret your result
Below your concept's range: Great margin — but check you're not under-portioning or over-pricing relative to competitors, both of which quietly cost you repeat business.
Within range: Healthy. Focus on keeping it stable — set up a weekly tracking rhythm and watch the trend, not the individual data point.
1–3 points above range: Usually operational — portion drift, waste, or a missed supplier increase. Audit your top 10 items by purchase value first; they typically account for most of the drift.
More than 3 points above range: Structural — your menu pricing hasn't kept up with ingredient costs, or there's significant untracked loss. Re-cost your best-selling recipes and compare theoretical vs actual food cost to find the gap.
Theoretical vs actual food cost: finding the gap
The food cost percentage this calculator gives you is your actual food cost — what your inventory movement says really happened. On its own it tells you there is a problem but not where it is. To locate the problem you need the other number.
Theoretical food cost is what your food cost should have been if every plate had gone out exactly to specification. Calculate it by multiplying each dish's plate cost by the number of units sold, then dividing the total by sales.
That variance is your waste, over-portioning, spoilage, comps, and theft, expressed as a single number. Well-run kitchens keep it under two percentage points. At five points or more, something systematic is happening and no amount of menu re-pricing will fix it — you have an operational problem, not a pricing problem.
Build accurate plate costs first with the recipe costing calculator, since the whole comparison depends on those figures being right.
Diagnosing a high food cost, in order
When the number comes back high, work through the causes in this sequence. It runs cheapest-to-check first, and in most kitchens the answer appears in the first three.
1. Check the maths before the kitchen
Confirm your COGS and sales cover exactly the same dates, that beverage cost has not crept into food COGS, and that your closing inventory count was complete. A surprisingly large share of alarming food cost numbers turn out to be a counting or period-alignment error rather than a real problem.
2. Portion drift
The most common genuine cause, and the easiest to fix. Portions expand quietly over months as new staff learn by watching rather than by specification. Weigh ten plates of your top three sellers against the recipe card — if they are consistently over, you have found several points of food cost without looking any further.
3. Untracked waste and spoilage
If waste is not being recorded, it is invisible in every report you have while still being fully present in your COGS. A waste log kept for two weeks — even a clipboard by the bin — usually reveals more than any spreadsheet analysis. Over-ordering is a frequent underlying cause, which is what par levels exist to control.
4. Supplier price increases
Prices move constantly and rarely with notice. Pull the last three months of invoices for your ten highest-spend ingredients and compare unit prices. A 12% rise on a major protein moves your whole food cost noticeably, and if menu prices have not moved with it, the gap is structural.
5. Unrecorded consumption
Staff meals, comps, tastings, manager meals, and losses all consume inventory without generating recorded sales. Each is legitimate, but each must be recorded and ideally valued separately. Untracked, they inflate food cost while looking like a mystery.
6. Menu mix shift
Your food cost can rise without a single thing going wrong operationally, simply because guests moved toward higher-cost dishes. Compare the sales mix across periods before concluding the kitchen is at fault — if a 38% food cost special became your best seller, the number is behaving exactly as it should.
Weekly tracking beats monthly
A monthly food cost figure is a post-mortem. By the time you see it, four weeks of overspending have already happened and the staff involved have forgotten the details. Weekly tracking turns the same number into something you can act on inside the period.
A workable weekly routine:
- Count on the same day each week, before service, ideally on your quietest morning. Consistency matters more than perfection.
- Count the same way every time — same units, same locations, same person where possible.
- Include everything: walk-in, freezer, dry store, and line stock. Line stock is the most commonly missed.
- Pull sales for exactly the period the count covers.
- Record the result and investigate any two-point move the same week.
Four data points a month reveal a trend that a single monthly figure cannot. Because food cost is half of prime cost, most operators count for both at the same time and get two metrics from one exercise.
What to do once you know the number
A high food cost has only three real responses, and most situations need a combination:
- Reduce cost — tighten portions, cut waste, renegotiate with suppliers, or re-engineer expensive dishes to use less costly components without changing what the guest experiences.
- Raise prices — if costings show prices have fallen behind ingredient inflation, this is the fastest correction available. Use the menu price calculator rather than applying a flat percentage across the menu.
- Change the mix — promote high-margin dishes through menu design, positioning, and staff recommendations. This lifts contribution without changing a single price or cost.
One warning: cutting quality is not on that list. Reducing portion sizes below what guests expect, or switching to visibly cheaper ingredients, improves food cost in the short term and reduces the covers those savings are calculated against in the longer one.
Frequently asked questions
Why is my food cost percentage so high?
The five usual suspects: portion drift, untracked waste, supplier price increases that never reached your menu prices, unrecorded consumption (staff meals, comps, theft), and menu mix shifting toward high-cost dishes. Our food cost guide covers how to diagnose each one.
Should beverage sales be included?
No — beverages run a much lower cost percentage, so blending them in makes food cost look artificially healthy. Track food against food sales and beverage against beverage sales separately.
How often should I calculate it?
Weekly is the standard for well-run operations; monthly is the minimum. The key is a consistent method — same inventory counting approach, same sales source — so the trend is trustworthy.
What's the difference between theoretical and actual food cost?
Theoretical food cost is what your food cost should be based on recipes and sales mix. Actual is what your inventory movement says really happened. The gap between them is your waste, portioning, and loss problem quantified — most operators aim to keep it under 2 points.
