Imagine a café ending Saturday with every table used. The owner checks the bank balance on Monday and wonders where the money went. Busy service tells you people ordered. It does not tell you what those orders cost.
Food cost percentage compares the cost of ingredients used with food sales over the same period. Calculate it with opening stock plus purchases minus closing stock, divided by food sales, then multiply by 100. Keep drinks and food separate if you are measuring only food.
The idea, at a glance
From shelf to a useful number.
- 01Count opening stock
Use consistent cost units.
- 02Add purchases
Match the same reporting period.
- 03Subtract closing stock
Find the ingredients used.
- 04Compare with sales
Investigate before choosing a fix.
Count what you used, not just what you bought
An invoice is money spent on supplies. Some of those supplies may still be on the shelf. Charging the whole delivery against this week's sales can make a quiet week look worse than it was. Skipping the stock count creates the opposite problem when you cook from ingredients bought earlier.
Choose a weekly cut-off when the kitchen is quiet. Count stock at cost, using the same units and valuation method each time. Record supplier credits and transfers consistently. Your accountant can help settle the treatment of taxes and adjustments before you compare periods.
Toast's food-cost explanation describes this stock-and-sales calculation. Its benchmarks concern other restaurant contexts; your own costs and service model matter more than copying a headline target.
Work through a small example
These invented figures show the arithmetic, not a target for your restaurant. Assume one location, no transfers and figures on a consistent tax basis.
| Weekly entry | Amount |
|---|---|
| Opening food stock | ₹12,000 |
| Food purchases | ₹18,000 |
| Closing food stock | ₹10,000 |
| Food used: 12,000 + 18,000 − 10,000 | ₹20,000 |
| Food sales | ₹60,000 |
| Food cost: 20,000 ÷ 60,000 × 100 | 33.3% |
The remaining ₹40,000 is not profit. Wages, rent, utilities, payment costs and other expenses still need paying. A calculation with zero sales is undefined; show that plainly rather than displaying a reassuring zero percent.
Investigate the difference before changing prices
Compare the stock-based result with what your recipe cards suggest you should have used. The gap can include waste, changed portions, missing purchases or counting mistakes. It is a question to investigate, not evidence that someone stole ingredients.
Pick one expensive ingredient. Check the invoice unit, recipe quantity and actual serving. A price entered per box while a recipe expects a kilogram can spoil the whole calculation. Use the inventory-count guide to make those units consistent.
Record waste as it happens. Toast's waste tracker documentation separates waste by reason. You can begin with a simple sheet; the useful part is knowing what happened.
Make one decision from the number
If purchase prices changed, update recipe costs. If portions vary, agree a serving measure with the chef. If prepared food repeatedly remains unsold, review batch size using the food-waste log.
Write one action, one owner and the next review date beside the weekly figure. Repeat the count before judging the change. The menu-pricing guide then helps you look at each dish without treating a percentage as the whole business.
