Ask a struggling restaurant owner their food cost and you'll hear a guess; ask a profitable one and you'll see a spreadsheet. Food costing — knowing exactly what every dish costs and pricing it deliberately — is the least glamorous skill in the food business and the most decisive: three points of food-cost drift is often the entire difference between profit and loss. Here is the complete method, from recipe cards to menu engineering.
Step 1: Recipe costing done honestly
- Every dish gets a recipe card: ingredients in grams/ml, current purchase rates, and — the step amateurs skip — yields: raw-to-usable conversion (onions peel to ~85%, chicken curry-cut yields ~70% from whole, paneer shrinks in cutting)
- Cost at usable rates: ₹200/kg raw chicken at 70% yield is ₹285/kg in the pan — recipes costed at invoice rates understate reality 15–30%
- Add the forgotten lines: oil absorbed in frying, garnish, accompaniments (the free salad isn't free), packaging for delivery formats
- Result: plate cost per dish — the number every other decision stands on
Step 2: Target percentages by format
Food cost percentage = plate cost ÷ selling price. Working bands: fine dining 28–35%, casual dining 30–35%, QSR 28–32%, cloud kitchens 25–30% (the aggregator commission forces it), cafés/bakeries 25–30%, bars 18–25% on beverages. These are targets, not laws — the real law is the rupee contribution: a 40% food-cost biryani leaving ₹180 on the table beats a 25% food-cost starter leaving ₹60. Chase contribution margin per plate alongside percentage; percentage discipline plus rupee awareness is the complete view.
Step 3: Price with method, not mimicry
- Baseline: plate cost ÷ target food-cost % gives the floor price (₹85 plate cost at 30% target → ₹283 → ₹285 menu price)
- Then adjust for position: signature dishes carry premiums (they're why customers came), commodity items track the market (your dal makhani lives in a comparison set), delivery menus price channel costs in
- Psychology: ₹295 vs ₹300 matters at casual price points; clean round numbers signal premium above ₹500; remove ₹ signs and grid-like price columns that invite comparison shopping
- Never price by copying the neighbour — their plate costs, rents and wastage aren't yours
Plot every item on two axes — popularity vs contribution margin: Stars (popular + profitable): feature, protect, never discount. Plowhorses (popular + low margin): re-engineer — portion tweaks, ingredient swaps, price nudges. Puzzles (unpopular + profitable): rename, reposition, have staff recommend. Dogs (neither): delete without sentiment. Run the matrix quarterly; menus that never change are menus slowly leaking.
Step 4: Control the drift
Costing is a system, not a ceremony: rate updates monthly (supplier price creep silently moves every plate cost — link recipe cards to a live rate sheet); theoretical vs actual — compare what sold-items should have consumed against actual stock depletion weekly; the gap is wastage/theft/portion-drift, and 2–4% gaps are found money; portion tools — ladles, scoops, weighing at the pass; standards without tools are suggestions; prep yields audited quarterly (a new commis peeling badly moves your onion cost 10%); and the daily food-cost flash in the MIS — purchases-to-sales ratio tracked so month-end never surprises. Kitchens that run this stack hold food cost within a point of target through price cycles; kitchens that don't discover their P&L in the accountant's autopsy.
How Aidwish helps
Aidwish installs costing systems in food businesses — recipe-card builds with yield studies, pricing architecture, menu-engineering reviews and the theoretical-vs-actual control rhythm — because margins are designed in the spreadsheet before they're earned in the kitchen.
