Restaurant food cost percentage: the formula and a worked example
How to work out food cost for a month, what a healthy number looks like, and where the money usually leaks.

Food cost percentage tells you how much of every rupee of food sales went on ingredients. It is the single most useful number for a restaurant owner after sales.
The formula
Food cost % = (opening stock + purchases − closing stock) ÷ food sales × 100
A worked example
For one month:
- Opening stock (counted on the 1st): Rs 200,000
- Purchases during the month: Rs 500,000
- Closing stock (counted on the last day): Rs 180,000
- Food used: 200,000 + 500,000 − 180,000 = Rs 520,000
- Food sales: Rs 1,600,000
Food cost = 520,000 ÷ 1,600,000 = 32.5%
What is a good number
Many restaurants aim for somewhere around 28% to 35%, but it depends on the menu. A karahi and BBQ place spends more on meat than a chai and paratha corner. Track your own number month by month; a sudden jump matters more than the exact figure.
Where it leaks
- Portions that grow during the rush
- Wastage that nobody writes down
- Staff meals not recorded
- Theft of expensive items such as chicken and oil
- Purchase prices rising without menu prices changing
Recipe cost per dish
For each dish, add up what goes into one plate. If a chicken karahi uses Rs 900 of ingredients and sells for Rs 2,600, its food cost is about 35%. Doing this for your top ten dishes shows which ones really earn.
Munshi's restaurant POS keeps a recipe for each dish, takes the ingredients off stock with every order, and shows a daily food-cost and wastage report.
