Use these simple calculators and tables to find your restaurant's food cost percentage, per-dish cost, and ideal menu price in seconds.
Calculating food cost percentage doesn't require fancy software or an accounting background. You need three numbers and about 60 seconds. This page gives you everything you need to calculate your restaurant's food cost percentage — overall, per dish, and per menu item — with worked examples and reference tables.
| Input | Where to Find It |
|---|---|
| Beginning Inventory | Physical count at the start of the period (dollar value) |
| Total Purchases | Sum of all food vendor invoices for the period |
| Ending Inventory | Physical count at the end of the period (dollar value) |
| Total Food Revenue | POS report: food sales only (exclude beverage) |
Step 1: COGS = Beginning Inventory + Purchases − Ending Inventory
Step 2: Food Cost % = (COGS ÷ Food Revenue) × 100
| Input | Your Numbers | Example |
|---|---|---|
| Beginning Inventory | _________ | $15,000 |
| + Purchases | _________ | $27,500 |
| − Ending Inventory | _________ | $14,200 |
| = COGS | _________ | $28,300 |
| Food Revenue | _________ | $85,000 |
| Food Cost % | _________ | 33.3% |
If you want a quick sanity check without doing a full inventory count, you can use the simplified version:
Quick Food Cost % = (Total Food Purchases ÷ Total Food Revenue) × 100
This isn't as accurate because it doesn't account for inventory changes, but it'll get you within a few percentage points for a rough check.
For each dish, you need the cost of every ingredient that goes on the plate — including cooking oil, garnishes, sauces, bread, butter, and anything else the customer receives.
| Ingredient | Qty | Unit Price | Line Total |
|---|---|---|---|
| Ground beef patty | 8 oz | $0.62/oz | $4.96 |
| Brioche bun | 1 | $0.65 | $0.65 |
| Lettuce | 1 oz | $0.08/oz | $0.08 |
| Tomato slice | 2 slices | $0.10 each | $0.20 |
| Onion | 1 oz | $0.06/oz | $0.06 |
| Pickles | 3 slices | $0.03 each | $0.09 |
| American cheese | 1 slice | $0.18 | $0.18 |
| Fries (side) | 5 oz | $0.12/oz | $0.60 |
| Cooking oil | — | — | $0.15 |
| Ketchup/mustard | — | — | $0.10 |
| Total Plate Cost | $7.07 |
Menu Price: $18.00
Food Cost % = ($7.07 ÷ $18.00) × 100 = 39.3%
That's high. Options to bring it down: reduce the patty to 6 oz (saves $1.24, brings cost to 32.4%), raise the price to $20 (brings cost to 35.4%), or switch to a less expensive bun.
If you know your plate cost and your target food cost percentage, calculate the minimum menu price:
Menu Price = Plate Cost ÷ Target Food Cost %
| Plate Cost | 25% Target | 28% Target | 30% Target | 33% Target | 35% Target |
|---|---|---|---|---|---|
| $3.00 | $12.00 | $10.71 | $10.00 | $9.09 | $8.57 |
| $4.00 | $16.00 | $14.29 | $13.33 | $12.12 | $11.43 |
| $5.00 | $20.00 | $17.86 | $16.67 | $15.15 | $14.29 |
| $6.00 | $24.00 | $21.43 | $20.00 | $18.18 | $17.14 |
| $7.00 | $28.00 | $25.00 | $23.33 | $21.21 | $20.00 |
| $8.00 | $32.00 | $28.57 | $26.67 | $24.24 | $22.86 |
| $9.00 | $36.00 | $32.14 | $30.00 | $27.27 | $25.71 |
| $10.00 | $40.00 | $35.71 | $33.33 | $30.30 | $28.57 |
| $12.00 | $48.00 | $42.86 | $40.00 | $36.36 | $34.29 |
| $15.00 | $60.00 | $53.57 | $50.00 | $45.45 | $42.86 |

If your number is above the high end for your type, it's time to investigate.
Knowing the formula is the easy part. Here's what to actually do with the numbers:
Calculate overall food cost weekly. Monthly is the minimum, but by the time you catch a problem at month's end, you've already lost 3–4 weeks of margin. Weekly catches problems faster.
Cost every dish on your menu. Most restaurant owners have a rough idea of their dish costs but haven't calculated them precisely. You'll almost always find surprises — dishes you thought were profitable that aren't, and dishes you underestimated that are actually stars.
Recalculate after every price change. When a vendor raises prices, immediately recalculate the affected dishes. A $0.50/lb increase on chicken doesn't sound like much, but if you sell 300 chicken dishes a week at 8 oz each, that's $75/week or nearly $4,000/year.
Compare actual to theoretical monthly. Calculate what your food cost should have been based on what was sold (theoretical), and compare it to what actually happened (actual). The gap is your waste, theft, and portioning variance.
If you're tracking all of this manually — counting inventory by hand, entering invoice data into spreadsheets, looking up prices for each ingredient — it eats hours every week. That's time you could spend on the floor, developing recipes, or actually running your business.
Vellin automates most of this process. You photograph your invoices with your phone, and the app reads every line — vendor, items, prices, quantities. Your food cost percentage updates in real time without manual data entry. The core features are free, so there's no cost to try it.
Don't forget hidden ingredients. Cooking oil, seasonings, bread service, and garnishes often get left out of plate cost calculations. They typically add 2–5% to the actual cost per plate.
Don't mix food and beverage. Always calculate food cost and beverage cost separately. Blending them hides problems in both categories.
Don't use catalog prices. Use your actual invoice prices, not the vendor catalog. Prices change weekly, and your actual delivered cost may differ from the list price.
Don't skip the inventory count. Without beginning and ending inventory, you're just looking at purchases — which doesn't tell you what you actually used. A 5-minute walk-through count each week gives you dramatically more accurate numbers.
Every restaurant owner should be able to calculate three things without thinking:
Overall food cost percentage — are you in range for your restaurant type?
Per-dish food cost percentage — which items are profitable and which aren't?
Ideal menu price — are your prices high enough to hit your target margins?
The math takes minutes. Building the habit of doing it regularly is what separates profitable restaurants from the ones that close.
