Food Cost 101: Costing Recipes and Pricing Your F&B Menu

Ask a warung owner what their fried chicken plate sells for and the answer is instant. Ask what it costs to make one portion and you’ll often get “hmm… maybe half of that?” Yet two dishes at the same selling price can earn wildly different profits — and without a cost-per-portion number, you will never know which menu items feed your business and which ones quietly eat it.

In F&B this number is your food cost: the total ingredient cost behind one sold portion. Calculating it requires no accounting degree. It requires a kitchen scale, your purchase receipts, and one focused afternoon per dish.

Start with a weighed recipe, not a guessed one

Take one bestseller. Write down every ingredient for ONE portion, in real measured quantities: 250 grams of chicken, 150 grams of rice, 30 ml of oil, 20 grams of chili, the garlic, the salt — down to the packaging and napkin if it’s a takeaway item. Don’t wave away the “small stuff”; on a thin-margin dish, seasonings and packaging can be the difference between profit and loss.

Now convert to money using your latest purchase prices. If chili costs Rp60,000 per kilo, 20 grams costs Rp1,200. Fill in every line, add it up, and you have your first number: recipe cost per portion.

Most people stop here. Two corrections turn this from “roughly” into “right.”

Correction one: yield — because ingredients shrink

The kilogram of chicken you buy is not the kilogram of chicken you serve. Bones get discarded, water cooks off, trimmings go in the bin. The ratio of usable weight to purchased weight is the yield.

Example: a whole chicken costs Rp38,000 per kg, and after breaking it down you can actually serve 65% of that weight (a 65% yield). The true cost of servable meat isn’t Rp38,000 per kg — it’s Rp38,000 divided by 0.65, about Rp58,500. That’s a gap of more than 50%, and it’s exactly why “roughly half” food-cost estimates miss by a mile.

You only need to measure each ingredient’s yield once: weigh before prep, weigh after. Vegetables, fish, meat — each gets its own number. Record it and reuse it until the supplier or the prep method changes.

Correction two: waste and portion creep

Two more leaks deserve a line in the math. First, waste: ingredients that spoil before use, food that doesn’t sell, dishes made wrong. Common practice adds 5–10% on top of recipe cost as a waste allowance — refine the number once you start tracking it for real.

Second, inconsistent portions. If the cook scoops by feel, Monday’s portion and Friday’s can differ by 20%. The fix is boring and it works: measuring scoops, a scale in the kitchen, and a written recipe taped to the wall. Consistent portions aren’t only about cost — customers notice getting the same plate every visit.

From food cost to menu price

Now the headline metric: food cost percentage = cost per portion divided by selling price. The common F&B benchmark sits around 25–35%. High-volume rice stalls can run above it; cafes built on drinks usually run far below — a milk coffee costing Rp7,000 and selling at Rp25,000 is a 28% food cost, which is precisely why beverages are the profit engine of F&B.

You can also run it backwards: if your fried chicken costs Rp9,500 per portion and your target is 32%, the minimum price is Rp9,500 divided by 0.32 — about Rp29,700, round to Rp30,000. If your local market will only pay Rp25,000, you have three honest options: cut the cost (new supplier, better yield), shrink the portion, or accept the thin margin and make sure the volume is there. The one option that doesn’t exist: pretending not to know.

Remember, food cost excludes wages, rent, gas, and electricity — all of that must fit inside the remaining margin. And if your city levies a restaurant tax, price it in from the start, as covered in restaurant tax PB1 explained.

Keeping it alive instead of one-and-done

Food cost calculations usually die the same death: built once in a spreadsheet, never updated — while chili prices double in a month. To make it stick:

• Cost your top 10 sellers first; the long tail can wait.
• Review volatile staple prices monthly, everything else quarterly.
• Keep recipes and costs in a system, not on paper — a POS with recipe management recalculates food cost automatically when ingredient prices change, and the margin-per-dish report becomes something you read, not build, as touched on in reading your daily sales report.

This afternoon, take one signature dish and cost it properly. Most F&B owners get a shock on the very first item — either the margin is far thinner than assumed, or they discover a dish they’ve been underpricing for years. Both are good news: now you know.
