How to Calculate Food Cost Percentage in a Restaurant (Formula and Indian Benchmarks)

Food cost percentage is the cost of food used divided by food sales, multiplied by 100. Calculate cost of food used as opening stock plus purchases minus closing stock.

Quick Answer: Food cost percentage is the cost of food used divided by food sales, multiplied by 100. Calculate cost of food used as opening stock plus purchases minus closing stock. For example, Rs 6,20,000 of food used on Rs 20,00,000 of food sales gives 31 percent. Most full-service restaurants plan for roughly 28 to 35 percent.

What is food cost percentage?

Food cost percentage shows how much of every rupee of food sales goes into buying the ingredients. If your food cost is 30 percent, then Rs 30 of each Rs 100 in food sales pays for ingredients and the remaining Rs 70 must cover rent, salaries, utilities, taxes, marketing and profit.

It is one of the first numbers an owner should know every week. A rise of even two or three points can remove most of an outlet's profit. Rent and salaries are hard to change quickly, but food cost can often be corrected within weeks by fixing recipes, portions, purchasing and waste.

There are two versions of the number, and confusing them causes many mistakes.

The gap between the two is where losses hide: waste, over-portioning, theft, wrong billing and supplier errors.

How do you calculate food cost percentage?

Use the standard formula in two steps.

Step 1: Cost of food used

Opening inventory + Purchases - Closing inventory = Cost of food used

Step 2: Food cost percentage

(Cost of food used / Food sales) x 100 = Food cost percentage

Worked example for one month

Calculation: 2,00,000 + 6,00,000 - 1,80,000 = 6,20,000. Then 6,20,000 / 20,00,000 x 100 = 31 percent.

Four rules that keep the number accurate

1. Use sales without GST. Tax is not your income.

2. Separate food from beverages. Food and bar have different cost structures. Track each separately.

3. Count stock on the same day and time each period. Mid-service counts distort results.

4. Value stock at purchase price, not selling price. Include all food items, including frozen and dry stores.

Also record staff meals, complimentary items and wastage separately so you know what they cost.

How do you calculate the cost of a single dish?

Recipe costing is the base of menu pricing. Cost every ingredient in the exact quantity used, including garnish and cooking oil.

Example: paneer tikka portion (illustrative prices)

If your target food cost for this dish is 30 percent, the selling price before tax is:

Plate cost / Target food cost % = 68.60 / 0.30 = about Rs 229

You might round to Rs 229 or Rs 249 after checking the market and your competitors. GST is added on top as per the applicable rate.

The prices above are examples. Update them with your own supplier rates every month, because ingredient prices move, especially vegetables, dairy and oil.

Why does actual food cost go above theoretical food cost?

Suppose your recipes say food cost should be 29 percent, but your stock count shows 33 percent. On Rs 20,00,000 of monthly food sales, that four-point gap equals Rs 80,000 a month, or about Rs 9.6 lakh a year. Where does it go?

Over-portioning. Cooks add an extra spoon or a larger cut.

Waste and spoilage. Poor storage, over-ordering, no first in first out (FIFO) discipline.

Prep losses not in the recipe. Trimming, yield and cooking loss not counted in costing.

Wrong or missing billing. Items served but not entered in the POS, or discounts given without approval.

Theft. Missing stock, short deliveries accepted without checking.

Supplier price creep. Rates rise without a check against agreed prices.

Free items. Staff meals, tastings and complimentary dishes not recorded.

Finding which cause is the largest tells you where to start. This is the type of problem we examined in the Grotto case study on margins in Gurugram.

How can a restaurant reduce food cost?

Work through these steps in order. Each one is practical and measurable.

1. Cost every recipe. Write standard recipe cards with weights and yields. A dish without a costed recipe is a guess.

2. Fix portion control. Use scoops, weighing scales, portion cups and pre-cut pieces. Train cooks with real examples.

3. Engineer the menu. Promote high-margin, popular items and reprice or remove weak ones. Use the same logic that bar teams use in bar menu engineering.

4. Control purchasing. Fix par levels, order from approved suppliers at agreed rates and compare quotes every month.

5. Check every delivery. Weigh and count against the invoice. Reject poor quality on the spot.

6. Store correctly. Label, date and rotate stock with FIFO. Keep temperatures correct.

7. Track wastage daily. Use a simple log with item, quantity, reason and who recorded it. Review it weekly.

8. Count stock regularly. Weekly counts for high-value items and monthly full counts reveal problems faster.

9. Use leftovers carefully. Convert trim and surplus into staff meals, stocks or specials, safely and within food safety rules.

10. Train the team. Cost control works only when kitchen and floor staff understand why it matters. Our article on restaurant SOPs and staff training in India shows how to document these routines.

How often should you check food cost?

A weekly number catches problems early. A monthly number alone tells you only after the loss has happened.

What mistakes make food cost numbers wrong?

Mixing food and beverage sales in one calculation

Including GST in sales

Skipping closing stock or counting it inaccurately

Forgetting staff meals, wastage and complimentary items

Using old ingredient prices in recipe costs

Not adjusting for yield and trim

Comparing different periods with different mixes of items

How does food cost connect to profit and break-even?

Food cost is the largest variable cost for most restaurants. When it rises, break-even sales rise as well, because each rupee of sale keeps less to cover fixed costs. This is why a wrong food cost can delay the point at which an outlet becomes profitable. For more on timelines, read how long a restaurant takes to turn profitable in India.
