Quick answer

To cost a recipe: standardise it, list every ingredient's as-purchased quantity and price, apply yield percentages for prep waste, add accompaniments and packaging, and divide by portions. The number you get drives every pricing decision — get it wrong and every menu price built on it is wrong too.

Three terms you must not confuse

Recipe cost (one batch), dish cost (one served portion, garnish included) and food cost percentage (dish cost ÷ menu price) answer different questions. The menu price conversation starts only after the first two are accurate.

The four inputs you need before starting

  1. A standardised recipe — exact quantities per batch, written down, followed by every cook.
  2. Current purchase prices — from your latest supplier invoices, not memory.
  3. Yield percentages — how much of each ingredient survives prep.
  4. Portion count — how many servings one batch actually produces (measured, not assumed).

The nine-step process

  1. Write the standardised recipe with as-purchased (AP) quantities.
  2. Record the current AP price for every ingredient.
  3. Apply yield percentage to each prep-waste ingredient: effective cost = AP price ÷ yield.
  4. Compute each ingredient's cost for the batch quantity.
  5. Sum to get total batch cost.
  6. Divide by measured portions per batch → base cost per portion.
  7. Add accompaniments: garnish, sides, condiments served with the dish.
  8. Add packaging for delivery/takeaway portions.
  9. Divide by menu price for food cost % — and re-check monthly.

Worked example — Palak Paneer, one portion

Spinach has a typical yield of 75–80% after stemming and blanching; paneer close to 100%. If 300g of AP spinach at ₹40/kg is required for a portion, the effective spinach cost is (0.3 × 40) ÷ 0.78 ≈ ₹15.4, not ₹12 — a 28% difference on one ingredient. Repeat that error across a full recipe and a dish you believe costs ₹78 actually costs ₹95+. At a ₹260 menu price, that's the difference between a healthy 30% and a deceptive 36.5% food cost.

Theoretical vs actual — the honesty check

Your costed recipe is the theoretical number. Reality adds over-portioning, spillage and inconsistent prep. Compare theoretical usage against actual stock consumption weekly; a gap above 4% means the kitchen isn't cooking the recipe you costed.

How KhanaOS helps: Recipe Builder stores standardised recipes with yields, ingredient prices update from purchase entries, and every POS sale computes actual-vs-theoretical variance automatically — the check most operators never have time to run by hand.

Frequently asked questions

What is the difference between recipe cost, dish cost and food cost?

Recipe cost is the ingredient cost of one batch of a standardised recipe. Dish cost is one served portion, including garnish and accompaniments. Food cost % is dish cost ÷ menu price. Confusing the three leads to systematically underpriced menus.

What is yield percentage in recipe costing?

The share of an ingredient that remains usable after prep — peeling, trimming, deboning. If 1kg of onion yields 850g usable, yield is 85% and your effective cost is purchase price ÷ 0.85. Skipping this step is the most common reason recipe costs are understated.

How often should recipe costs be updated?

High-volume dishes monthly, the full menu quarterly — or continuously with software. Indian ingredient prices are volatile (onions moved ₹25→₹70/kg in three weeks in March 2025), so a recipe costed once a year is fiction by month three.
