Food Cost
Meaning, Formula & How to Calculate It
4 min readFood cost is the total amount a restaurant spends on ingredients and raw materials to prepare the dishes it sells, expressed as a percentage of food revenue. Biggest line item on most restaurant P&Ls, and the one owners tend to underestimate until margins start shrinking.
What Is Food Cost?
In India, full-service restaurants typically operate between 28% and 35%. QSRs sit lower (22% to 28%) because of standardised recipes and bulk procurement. Fine-dining runs higher, 33% to 38%, premium ingredients being the main driver. But these are rough industry ranges, not rules. Your actual number depends on your menu, your suppliers, and how much the kitchen wastes every week.
How to Calculate Food Cost
Two formulas matter here. The first gives you your actual food cost percentage for a specific period:
Food Cost % = (Opening Stock + Purchases − Closing Stock) ÷ Food Sales × 100
| Component | What It Means |
|---|---|
| Opening stock | Value of ingredients in your kitchen at the start of the period |
| Purchases | Everything you bought during that period |
| Closing stock | What remains unused at the end |
| Food sales | Total revenue from food items only (exclude beverages) |
The second is ideal food cost, calculated from recipe cards. Add up ingredient cost per dish based on standardised portions, multiply by units sold, divide by revenue. The gap between actual and ideal is where real problems hide: wastage, over-portioning, pilferage, or vendor price creep nobody flagged.
Food Cost Example
Say a biryani restaurant in Aundh, Pune runs these numbers for March 2025 (illustrative, not real financials):
| Item | Amount |
|---|---|
| Opening stock (1 March) | Rs.1,85,000 |
| Purchases during March | Rs.4,72,000 |
| Closing stock (31 March) | Rs.1,63,000 |
| Food sales for March | Rs.14,80,000 |
Calculation: (1,85,000 + 4,72,000 − 1,63,000) ÷ 14,80,000 × 100 = 33.4%
For every Rs.100 of food sold, the kitchen spent Rs.33.40 on raw materials. If the target was 30%, that 3.4-point gap needs investigating. Maybe the basmati supplier raised rates in February and nobody renegotiated. Maybe portion sizes drifted on the dum biryani. Or spoilage in the walk-in cooler because someone left the door ajar overnight. The number tells you something is off. Not what.
Why Food Cost Matters for Indian Restaurants
Rent is fixed. Salaries are mostly fixed. Ingredients are the one major expense you can actually move week to week, which makes this the primary lever for cost control in any food business.
A 2-percentage-point reduction on Rs.15 lakh monthly sales saves Rs.30,000 a month. Rs.3.6 lakh a year. For a single-outlet restaurant in Navrangpura, Ahmedabad, that is a staff member’s annual salary. And the fix is often small: switching one vegetable vendor, tightening portion scoops, or counting stock weekly instead of monthly. The reduction guide covers specific tactics.
At Petpooja, the pattern we see across restaurant clients is consistent: outlets that track weekly catch problems before they compound. The ones checking once a quarter find the damage after it is done.
How Petpooja POSS Tracks Food Cost
Petpooja POSS ties every menu item to a recipe card with standardised ingredient quantities. Bill a dish, and the system deducts ingredients from inventory on its own. End of the week, you get actual versus ideal without touching a spreadsheet. The calculator template works if you want to run the numbers manually first, and the know your food cost guide walks through the broader P&L picture.
Frequently Asked Questions
What is a good food cost percentage for an Indian restaurant?
28% to 35% for most full-service restaurants in India. QSRs run lower because of bulk procurement; fine dining pushes higher. There is no single correct number. It depends on your format, your menu, and your break-even point.
How is food cost different from cost of goods sold?
COGS covers everything sold: beverages, packaging, disposables, the lot. This metric is the subset covering only raw ingredients for preparing dishes. Most restaurant accountants track them separately because margin profiles differ sharply between food and drink.
Why does my actual food cost differ from ideal food cost?
Wastage, spoilage, over-portioning, pilferage, or unrecorded vendor price changes. If the gap is under 2 percentage points, that is normal kitchen variance. Above 3 to 4 points, something specific needs investigating.
How often should I calculate food cost?
Weekly, at minimum. Monthly is too slow. A cloud kitchen chain in Surat that switched from monthly to weekly tracking found Rs.47,000 in unrecorded spoilage in the first month alone (illustrative scenario based on patterns we see across Petpooja clients).
Does GST affect food cost calculation?
Exclude GST from both your purchase costs and your sales revenue when calculating the percentage. You want the pre-tax numbers on both sides, otherwise the ratio gets distorted. Input tax credit on purchases, where applicable under the CGST Act, 2017, is a separate accounting line.
Can food cost vary by season in India?
Yes, and wildly. Tomato prices in India have swung from Rs.20/kg to Rs.120/kg within a single quarter. Onion and potato follow similar cycles. Restaurants that lock in rates through quarterly vendor contracts or swap in frozen alternatives for high-volatility items keep their numbers steadier.
