How to calculate a dish's food cost (and price it with judgment)

El food cost es cuánto te cuestan los ingredientes de un plato, expresado como porcentaje de su precio de venta. Es el primer número que mira cualquier gastronómico, y el que más se calcula mal. El error típico: costear con el precio del kilo que compraste, sin descontar lo que se pierde en el camino.

1. Armá la ficha técnica

Cada plato necesita una receta estándar: todos los ingredientes, con la cantidad exacta que lleva una porción. Si la receta está solo en la cabeza del cocinero, el costo (y el sabor) cambia cada vez que cambia el cocinero.

2. Calculá el rendimiento de cada ingrediente

Casi nada se usa tal cual se compra. El lomo se limpia, la papa se pela, el pescado se filetea. El rendimiento es el porcentaje que queda útil después de limpiar:

Si comprás un kilo de lomo a $24.000 y después de limpiarlo te quedan 750 g, el rendimiento es 75% y el kilo útil te cuesta $24.000 ÷ 0,75 = $32.000, no $24.000.

3. Sumá el costo de la porción

IngredienteCantidadCosto
Lomo (kilo útil a $32.000)220 g$7.040
Papas y manteca para el puré250 g$1.200
Salsa de vino tinto60 ml$600
Aceite, sal, hierbas (se estima un 5%)—$440
Total de la porción$9.280

4. Del costo al precio

Con un food cost objetivo del 30%, el precio de venta sale de dividir el costo por ese porcentaje: $9.280 ÷ 0,30 = unos $30.900. Al revés, si ya tenés el precio, el food cost es costo ÷ precio.

5. Los errores que más plata hacen perder

Food cost is what a dish's ingredients cost you, as a percentage of its menu price. It's the first number any restaurateur checks, and the one most often miscalculated. The classic mistake: costing with the price per kilo you paid, without deducting what's lost along the way.

1. Build the recipe card

Every dish needs a standard recipe: every ingredient, with the exact amount per portion. If the recipe only lives in the cook's head, the cost (and the taste) changes every time the cook does.

2. Work out each ingredient's yield

Almost nothing is used as purchased. Tenderloin gets trimmed, potatoes peeled, fish filleted. Yield is the usable percentage after trimming:

If a kilo of tenderloin costs $24,000 and 750 g remain after trimming, the yield is 75% and the usable kilo costs $24,000 ÷ 0.75 = $32,000, not $24,000.

3. Add up the portion

IngredientAmountCost
Tenderloin (usable kilo at $32,000)220 g$7,040
Potatoes and butter for the mash250 g$1,200
Red wine sauce60 ml$600
Oil, salt, herbs (about 5%)—$440
Portion total$9,280

4. From cost to price

With a 30% target food cost, the menu price is the cost divided by that percentage: $9,280 ÷ 0.30 = $30,900. The other way around, if you already have the price, food cost is cost ÷ price.

5. The mistakes that cost the most
