How it works

The FL ratio (Food & Labor ratio) is the single most important profitability metric for restaurant operators. It combines your two largest variable costs into one percentage of revenue.

Food Cost % (FC) FC% = Ingredient cost ÷ Selling price × 100
FL Ratio FL% = (Ingredient cost + Labor) ÷ Selling price × 100
Ingredient cost Sum of (unit price × quantity used) for each ingredient in the dish
Labor allocation Portion of prep/cooking labor cost attributed to one serving of this dish

Example: Grilled salmon sells for $22.00. Ingredients (salmon fillet 200 g @ $0.08/g + lemon 0.25 @ $0.50 + oil 15 ml @ $0.01/ml) = $16.50 + $0.13 + $0.15 = $16.78. Labor allocated = $3.00. FC% = 16.78 ÷ 22 × 100 = 76.3% (red) — a premium protein with tight margins. FL = (16.78 + 3) ÷ 22 × 100 = 89.9% (red). Adjust price or portion size accordingly.

Frequently asked questions

What is a good FL ratio for a restaurant?
Industry consensus targets an FL ratio below 55% for full-service restaurants. That leaves roughly 45% of revenue to cover rent, utilities, packaging, insurance, and profit. Quick-service (QSR) operators often target FL below 50% because of lower front-of-house labor. Fine dining can tolerate up to 58–60% if average check size is high enough to generate absolute dollar margin. Anything consistently above 65% signals the business model needs repricing or portion adjustment.
What is a good food cost percentage?
A food cost (FC%) between 28% and 32% is considered ideal for most restaurant concepts. Fast-casual concepts may run 25–30%, while ingredient-heavy dishes (steaks, seafood) can push 35–40% — which is acceptable only if those dishes drive high ticket averages and labor per dish is low. The target isn't universal; it depends on your price point and labor structure.
How do I calculate labor cost per dish?
Take your total kitchen labor cost for a period (e.g., a shift or a week), divide by the number of covers served in that period to get a per-cover average. For a more accurate per-dish figure, track prep time per item and multiply by the cook's hourly rate including taxes and benefits. Example: a dish requiring 4 minutes of skilled labor at $25/hr fully loaded = 4/60 × $25 = $1.67 labor per serving.
Why enter ingredients as unit price × quantity rather than a lump sum?
Entering each ingredient separately lets you spot which components drive cost most. When beef prices rise, you can quickly see how it affects every dish that uses beef. It also makes it easier to evaluate portion adjustments — reduce the salmon from 200 g to 180 g and see the new FC% instantly without re-doing mental math.
