How to calculate food cost percentage
The formula, a free calculator for one dish or a whole month, and five mistakes that make food cost look better than it is.
Read the articleFoodNormIQ reads your supplier invoices, re-costs every recipe they touch and shows what each dish leaves you in the restaurant and on Wolt. You see the change the morning it happens, not when the month closes.
Live at Vega Fresh Bar, Skopje · about 300 supplier invoices read every month · +18% profitability identified
| Dish using beef | Plate cost | Wolt margin |
|---|---|---|
| Classic Smash | €2.51 | 39.4% |
| Double Smash | €3.96 | 36.2% |
| Bacon Smash | €3.16 | 37.4% |
| Chili cheese fries | €1.48 | 38.2% |
2 dishes are below your 38% Wolt target. To bring Double Smash back, its Wolt price needs to be €13.70 (now €12.90).

Where margin leaks
By the time the month closes, the money is gone. These four leaks sit underneath the percentage, and each one is visible earlier in the data you already have.
A 12% rise on one ingredient changes the cost of every recipe that uses it. Nobody re-costs the spreadsheet until it's too late.
Trim, cooking loss, sub-recipes and prep waste mean you buy more than you serve. Costing from the invoice alone flatters every dish.
Commission and packaging come off before anything reaches you. A higher Wolt price can still leave much less per order.
What the recipes say you used and what you actually bought drift apart quietly, one tray at a time.
Examples from the Bunbury & Co sample kitchen.
Classic Smash, one recipe, one plate cost of €2.51. On Wolt the menu price is a euro higher, and it still leaves €2.25 less per order once commission and packaging are paid.

The product
FoodNormIQ is organised around the work in a kitchen: buying, costing, selling and counting. This week pulls the few changes worth money to the top, so you don't have to read every report.
See price changes before they become margin problems.
Know exactly what each dish costs today, and what it cost before.
Know what each channel actually leaves you.
Know what should be on the shelf.
Decide ahead, and see what the kitchen really makes.
Getting started
Recipes in a binder, invoices as photos and odd POS exports are normal. Setup is done with you, not handed to you.
Binders, spreadsheets, photos or the chef's notes become structured recipes with yields and sub-recipes. We confirm the uncertain ones with your chef.
We read your past invoices. From then on you forward new ones to your own intake address, and your POS sends the day's sales each night.
Costs, stock and channel margins are current when you open the app, with the changes worth acting on at the top.
Your team signs in with email or Google. Each person sees only the areas you allow, and every change is logged with who made it.
About
I've sat on both sides of the invoice: first buying and pricing for a large portfolio, then building the reports that show where the money goes. FoodNormIQ puts both into one tool for independent kitchens.

The buyer. For close to a decade I led sales and purchasing at GermanPX, across tobacco, spirits, electronics and perfumes. I owned pricing and margin for the whole portfolio, managed a multi-million-euro purchasing budget and negotiated with international suppliers. I learned how quietly a good product line stops making money when input prices move and nobody re-costs anything.
The analyst. Since 2022, as a Business Intelligence consultant at Data Masters, I've built more than 100 Power BI solutions on sales, margin, stock and P&L for leading retailers and distributors in North Macedonia, including KAM, Makpetrol, Neptun and Žegin.
Why kitchens. Large companies have whole teams for this. An independent kitchen has the owner, late at night, with a folder of invoices. FoodNormIQ started in one of them, Vega Fresh Bar in Skopje: every invoice read, every recipe costed to the gram, every sale counted in the shop and on Wolt. For the first time the owner could see which dishes are worth cooking.
You'll deal with me directly, not a support queue. I'd rather sit with you in your kitchen than send you a manual.
Give every independent kitchen the margin discipline the big chains have, without hiring an analyst.
Kitchens where every price decision comes from numbers: each invoice read, each dish costed, each channel counted, every week.
I do the setup and the digging; you make the decisions. Your recipes and past invoices are loaded for you, and a short weekly review follows every action through to its effect.
“We had more than 2,500 supplier invoices in folders and nobody had time to read them. Now every dish has a real cost, in the shop and on Wolt. For the first time I set prices from numbers, not from feeling.”
Send me one week of invoices and your menu prices. Within a few days you'll see what your dishes really cost and where the margin leaks. The first conversation is on me.
