How to calculate food cost and recipe cost.

Know what one slice, one cookie or one cup really costs you — then price it so every sale leaves money for rent, salaries and profit.

What food cost % means

Food cost % tells you how much of your selling price goes into ingredients and packaging. The rest — your gross margin — has to pay rent, salaries, gas, power and profit.

Food cost % = Cost of one portion ÷ Selling price (before GST) × 100Example: a slice costs ₹38 to make and sells for ₹100 before GST → food cost 38%.

There is no single “correct” number. Cakes, breads and cold coffee each behave differently. What matters is that you know the number for every item and notice when it moves.

Cost a recipe in 5 steps

  1. List every ingredient — including garnish, sprinkles, oil for greasing, and the box, base or cup it goes out in.
  2. Use today's purchase price per kg, litre or piece — from your latest supplier bill, not last year's memory.
  3. Convert to the quantity used. 250 g of chocolate bought at ₹380/kg costs ₹95.
  4. Add a wastage allowance for trimming, spillage, test bakes and cream left in the piping bag.
  5. Divide by the number of portions the batch really gives — count the slices, don't assume.

Do this once per size. A half-kg cake is rarely exactly half the cost of a 1 kg cake — the box and decoration don't halve.

Recipe cost calculator

Change any number. Quantities in grams or ml use a price per kg or litre; pieces use a price per piece.

Set the price from the cost

Turn the formula around to find a price that hits your target food cost:

Price before GST = Cost per portion ÷ Target food cost %₹38 cost at a 35% target → ₹38 ÷ 0.35 = about ₹109. Round to a menu-friendly ₹110.
Cost / portion₹38
÷ 0.3535% target
Price₹109

On the menu₹110

Then add GST as your CA advises and check the final number against what customers in your area will pay. If the market price is lower, fix the recipe or the portion — not your margin.

Common mistakes

  • Forgetting packaging. A cake box and base can cost more than the cocoa.
  • Using old prices. Cream, butter, chocolate and nuts change price often. Re-cost when they do.
  • Counting GST as income. Compare cost with the price before GST.
  • Ignoring yield. If a batch “should” give 12 slices but staff cut 10, your cost per slice is 20% higher.
  • Costing once and forgetting. Food cost is a number to watch every month, not a one-time sheet.

Questions

Food cost FAQ

What is a good food cost percentage?

There is no single right number. Many food businesses look at a range of roughly 25–35%, but cakes, breads and beverages each behave differently. Track your own number item by item and watch the trend.

Should packaging be part of food cost?

Yes, if it goes out with every sale. Cake boxes, bases, cups and lids are part of what one portion costs you.

Is GST part of food cost?

Compare cost with your selling price before GST. GST you collect is not your income, so including it makes your food cost look better than it is.

How often should I re-cost recipes?

Whenever a main ingredient changes price, and at least once a month for items with dairy, chocolate or nuts, whose prices move often.

Does food cost include staff salary and rent?

No. Food cost is ingredients and packaging only. Rent, salaries, power and gas are paid from the margin that is left after food cost.
