Free food cost calculator for restaurants (2026)

Short answer: food cost percentage = ingredient cost ÷ menu price × 100, most venues target 28–35% per dish, and the target-price version (ingredient cost ÷ target %) is how you price new dishes instead of guessing. The calculators below do both, plus the batch-to-portion conversion that trips up soups, sauces and bakes. Underneath them: the benchmarks by category, the dollars-versus-percentage rule that stops good dishes being cut, and the re-costing rhythm that keeps January’s numbers true in July. For the full method with worked recipe cards, see how to calculate food cost; this page is the tool.

The rule that stops bad menu decisions: percentages diagnose, dollars decide. A steak at 38% contributing $14 a plate out-earns a salad at 24% contributing $7, so the steak stays and gets promoted while the percentage purist would have cut it. This is the heart of menu engineering: promote high-DOLLAR dishes, fix or hide high-percentage-low-dollar ones.

Keeping the numbers true

A costing is a photograph, and supplier prices keep moving after the shutter. The rhythm that works: touch-price your five biggest sellers monthly (five minutes with the latest invoices), full re-cost quarterly, and an immediate re-cost when any key ingredient moves more than a few percent. Then close the loop with reality: the stocktake tells you actual usage versus what the recipe cards promise, and the gap between theoretical and actual food cost is where portioning drift, waste and shrinkage hide. A dish can be priced perfectly on paper and still bleed in the pan.

Mistakes the calculator cannot fix

  • Costing the protein and forgetting the oil, garnish, bread and butter, small lines add whole points.
  • Using January’s supplier prices in July.
  • Cutting a 38% dish that contributes $14 a plate because the percentage looked scary.
  • Pricing takeaway without the packaging line.
  • Perfect recipe cards, no stocktake, so theoretical and actual food cost drift apart unseen.

Frequently asked questions

How do I calculate food cost percentage?
Ingredient cost of the dish divided by its menu price, times 100. A plate costing $4.20 in ingredients sold at $14 runs 30% food cost. Cost EVERY component from recipe cards (including oil, garnish and the roll you forget), use current supplier prices, and recalculate when prices move. The calculator on this page does the arithmetic and the target-price version in one step.

What is a good food cost percentage?
Most venues target 28–35% per dish, with a blended venue-wide target near 30%. Context matters: beverages often run 15–25%, proteins 35%+, and a high-cost dish can still be your best earner because margins bank dollars, not percentages. A $22 dish at 36% contributes $14.08; a $9 dish at 25% contributes $6.75. Use the percentage to spot outliers, and dollars to choose what to promote.

How do I price a dish from a target food cost?
Divide the ingredient cost by the target percentage: a $4.60 plate at a 30% target prices at $15.33, which you would round to menu-friendly $15.50 or $15.90. The calculator shows 28/30/32/35% targets side by side so you can see the range, then apply judgement: what the neighbourhood pays, what the dish looks like, and where it sits in the menu’s story.

Should food cost include packaging and card fees?
For delivery and takeaway pricing, yes, add packaging as a per-dish cost line (often $0.80–1.50) before applying the target, or your takeaway margin quietly runs points below the dine-in number. Card fees and commissions are channel costs rather than dish costs; price the CHANNEL (marketplace markups, delivery fees) rather than loading them into every dish.

How often should I re-cost dishes?
Touch-price the five biggest sellers monthly and run a full re-cost quarterly, plus immediately when a key ingredient moves more than a few percent. Supplier price creep is the silent killer: a dish costed at 30% in January is often 34% by winter without a single decision being made. Recipe cards in a system (rather than a chef’s head) make the re-cost a ten-minute job.

What if my food cost is fine but profit is not?
Then the leak is elsewhere in prime cost or the channel mix: labour hours drifting up, portioning inconsistency between cooks, waste and shrinkage between invoice and plate, or a growing share of sales paying 30% marketplace commissions. Food cost percentage is one gauge on the dashboard: pair it with the prime cost and channel numbers before concluding the menu is the problem.
