Recipe Costing: Know What a Plate Costs You Before You Price It

Pricing by feel, or by copying the shop next door? That's how you bleed margin without noticing. You watch a plate sell and feel good, but you don't really know what it costs you until the end of the month, when the profit is gone and you can't say where it went. In this guide we cost a full plate with real numbers, factor in waste, show you the mistake most restaurants in Saudi Arabia make when they work out food cost percentage, and how to price back from your target instead of guessing.

A worked example: cost a burger plate step by step

Let's start with a plate you know: a burger with a side of fries. To find the plate cost, you write down every ingredient, its quantity, and its unit price, then multiply. Line cost = quantity times unit price, and adding up all the lines gives you the plate cost. This is an example with clean numbers, swap them for your own supplier's:

The plate cost comes to 9.75. That's your base number, and every pricing decision after it builds on it. Notice the beef alone is more than half the cost, so any small move in the price per kilo of beef shakes your whole profit, and that's the first ingredient whose price you watch.

Waste is not a detail: the usable kilo costs you more

The number above assumes you use every gram you buy, and that never happens. Produce gets trimmed, meat shrinks, and there is normal spoilage. If you buy a kilo of tomatoes at 9 and 10% goes to waste between trim and spoilage, the usable kilo does not cost you 9, it costs you: 9 divided by 0.90 = 10.00 per actual kilo. That means every salad or produce portion on your plate has to be costed at 10, not 9.

The rule is simple: take the purchase price and divide it by the usable share (100% minus the waste percentage). The more waste, the higher your true cost per kilo. Ignore it and your plate cost comes out lower than reality, you price off a false number, and the gap piles up across thousands of plates a month.

The mistake that lies about your profit: calculate on the net price, not the gross

Here's the thing most foreign calculators miss: in Saudi Arabia the menu price includes VAT, currently 15% per the Zakat, Tax and Customs Authority. If you work out food cost percentage by dividing cost over the price shown to the customer, the percentage lies to you, because part of that price isn't yours in the first place, it's tax you collect and hand over to the state.

Let's run it on our burger. Its menu price is 32 (VAT inclusive). The net = 32 divided by 1.15 = 27.83. The correct food cost percentage = plate cost divided by net = 9.75 divided by 27.83 = 35%. If you slip and divide by the gross 32, you get 9.75 divided by 32 = 30.5%, a number that reassures you while you're actually at 35%. That's a 4.5 point gap, and it can be the difference between a plate that makes money and one that bleeds.

Common food cost percentage ranges by concept

So what's a reasonable percentage? There's no single number for everyone. The ranges below are rough rules of thumb operators use as a starting point, not measured market data, so treat them as a signal: if an item sits far outside its range, check the recipe and the price:

Specialty coffee usually runs a lower percentage, which is why the drink margin looks tempting, but the other operating costs eat into it. If your concept is a cafe, we broke down the cost of opening a specialty coffee shop in Saudi Arabia in detail. And bakeries and dessert shops live on recipe-cost accuracy because their ingredients are measured in grams and their waste is higher; if you run a bakery, a POS for bakeries and dessert shops keeps the recipes and the cost together.

Price back from your target: from cost to menu price

Instead of working out the percentage after you price and getting a nasty surprise, flip the equation: set the food cost percentage you want to hit, and work the price out from it. If your target is 30% for the burger: net price = plate cost divided by target = 9.75 divided by 0.30 = 32.50. That's net, and we sell at a tax-inclusive price, so we add the tax: 32.50 times 1.15 = 37.375, roughly 37.4.

Round it to a clean menu number, and round up, not down, to protect your margin: make it 38. That way your actual percentage drops a hair under 30% (because 38 nets 33.04 against a 9.75 cost, so 29.5%), and that's in your favor. The rule: price from the target, then round up, and make sure the price still sits right with the customer against the market.

Cost your whole menu in 6 steps

Costing one plate is easy, the whole menu is the real work. Don't try to do it all in one go and tie yourself in knots, take it in order:

1. 1
   Start with your top 10 sellers

   The items that sell most are the ones that move your profit. Price them right first before you chase the rest, because they give you the biggest impact for the least effort.

2. 2
   Weigh the actual portions

   Don't rely on the recipe on paper. Weigh what actually leaves the kitchen, because the cook usually plates more than what's written, and those extra grams eat your margin quietly.

3. 3
   Get real supplier prices

   Open your latest purchase invoices, not last year's prices. Prices move and your cost moves with them, so costing on an old price is just costing wrong.

4. 4
   Add the yield factor

   For every ingredient with trim or spoilage, divide the purchase price by the usable share as we saw above, so you cost on the actual kilo.

5. 5
   Calculate the percentage on the net

   Divide the plate cost by the price divided by 1.15, not by the gross price, so the percentage comes out honest and you can hold it against your target with confidence.

6. 6
   Flag the items above your target

   Any item above your target: either raise its price, shrink the portion, find a cheaper supplier, or drop it from the menu. The menu is not sacred, edit it by the numbers.

Delivery is another story: count packaging and commission before you celebrate the margin

A plate at 30% in the dining room can lose money on delivery, because delivery adds costs that are not in the plate calculation: packaging (box, bag, cutlery) and the platform commission. If packaging costs you roughly 1.50 per order, your actual delivery cost becomes 9.75 + 1.50 = 11.25 before we even count the commission. And delivery-app commission usually ranges between 15% and 30% depending on the app and your deal, and it comes off every order.

Before you call delivery a moneymaker or a money pit, cost the whole order: ingredients + packaging + commission. We built a delivery-app commission calculator that gives you the net per order after every deduction, run it with your numbers and see the real picture.

Bottom line: plate cost isn't a guess, it's a table you write once and keep current. Cost by the gram, factor in waste, divide by the net and not the gross, and price back from your target. That way every item on your menu works in your favor, and you know exactly where you make money and where you bleed well before the end of the month.
