Food Cost Calculation Template: A Weekly Sheet, a Plate Cost Card and Two Worked Examples

What a normal food cost looks like

According to the National Restaurant Association Operations Data Abstract (FY2024 medians, as reported by Duckhub, updated October 3, 2026), the median food and beverage cost is about 32.0% of sales for full-service restaurants and 32.4% for limited-service. Those are medians across many concepts; a pizza place and a steakhouse will sit far apart. The useful number is your own, measured the same way every week, and the trend in it.

Template 1: the weekly food cost sheet

Count inventory at the same time each week, before the first delivery, and keep food separate from beverage and paper goods.

1. Week ending: date and who counted.
2. Beginning inventory ($): last week's ending count.
3. Purchases ($): every food invoice dated this week, minus credits for returns.
4. Ending inventory ($): this week's count, at latest invoice price.
5. Cost of food used: line 2 + line 3 − line 4.
6. Food sales ($): from the POS, food categories only, before tax and tips.
7. Food cost %: line 5 ÷ line 6 × 100.
8. Target and gap: your target, and the dollar gap (line 6 × the percent difference).

A $712 weekly gap is about $37,000 a year. It usually comes from a few dishes priced off old invoices, portions drifting, or waste nobody logs, which is what the plate cost card finds.

Template 2: the plate cost card

One card per menu item. Columns: ingredient, portion, purchase unit and price, yield percent (what is left after trimming or cooking), cost per portion. Sum the column, then menu price = plate cost ÷ target food cost %.

Leave out the yield and the card says $4.50, and the dish is priced about 77 cents too low on every plate. Update each card when a main ingredient's invoice price moves more than about 5%, and recheck the menu price. The free restaurant profit calculator shows what food cost, labor and rent leave as profit.

A 20-minute weekly count

The weekly sheet only works if the count is fast enough to happen every week. Three habits get it under half an hour for a typical independent kitchen:

• Count in shelf order. Print the count sheet in the order items sit on the walk-in, dry storage and freezer shelves, so the counter walks once.
• Count proteins, dairy and produce by weight or case; skip the pennies. Spices and condiments under a few dollars each can be estimated as a fixed amount; they rarely move the percent.
• Price at the latest invoice. Keep a column for unit price and update it from invoices as they arrive, so the count turns into dollars with one multiplication.

Two people counting, one calling out and one writing, beats one person doing both. Same day, same time, same order, every week, or the week-to-week change is noise.

Reading the gap

• Weekly % up, plate costs unchanged: portions, waste, comps or theft. Spot-check portions on the line and start a waste log.
• Plate costs up: supplier prices moved. Reprice, substitute or renegotiate.
• One week jumps, next week drops: usually a counting error or an invoice dated into the wrong week.
• Food cost fine, profit thin: look at labor. The same NRA medians put labor with benefits at 36.5% of sales for full-service restaurants.
