How to Use Recipe and Portion Costs When Considering Menu Prices

Start with a fixed recipe and serving size

Choose the version of the recipe you intend to serve, then write down each ingredient, the amount that goes into the batch, and the unit used to price it. Define the plated serving size as well. A batch cost only becomes a useful per-portion figure when the recipe and the portions being counted are clear.

Use the ingredient amounts actually put into the recipe and a current cost for each ingredient. If a purchase comes in a different unit from the recipe, convert it to a matching unit before multiplying. Decide which recipe components are included in the ingredient total and apply that same scope whenever you repeat the calculation.

• Record the recipe quantities and their units.
• Set one serving size that matches the portion you plan to sell.
• Keep the purchase cost and recipe amount in matching units.
• Include the same ingredients and recipe components each time you cost the dish.

Calculate ingredient costs and the full batch cost

Repeat the calculation for each ingredient, then add those ingredient costs to get the full recipe batch cost. If the recipe changes, update its quantities and recalculate; do not keep using a total from an older version of the dish.

For ingredients that are purchased in packs, calculate a cost for the unit used in the recipe before multiplying. For example, if a recipe amount is measured by weight, first express the purchase cost as a cost per matching weight unit. Keep any conversions written beside the recipe so another person can follow the same arithmetic.

Measure the actual yield and cost per portion

Prepare the recipe using the version you just costed. At the defined serving size, count the portions the batch actually produces. Use that actual yield rather than an assumed serving count. If portions vary, choose and record a consistent portion size, then recost when the standard serving changes.

1. Cost the full batch from its listed ingredient quantities.
2. Portion the prepared batch using the serving size you defined.
3. Count the portions the batch actually makes and record that yield.
4. Divide the full batch ingredient cost by the actual portion count.

Choose a food-cost target and calculate a starting price

Use the food-cost target you choose for your own operation. Treat it as a percentage and convert it to a decimal for the calculation: divide the percentage by 100. This guide does not select a target for you.

Keep the cost definition consistent. If the portion cost includes a recipe component, use that same portion cost when you compare a candidate price with the target. If the recipe, yield, portion, or chosen target changes, run the calculation again with the updated inputs.

Hypothetical worked example

Check a proposed price against the target

Run this check for a menu price you are considering, then compare its implied percentage with the target you chose. If the result does not line up with your target, review the recipe cost, measured yield, portion size, and proposed price inputs. Confirm which input you want to change before updating the calculation.

• Confirm the recipe cost and portion size are current.
• Divide the per-portion ingredient cost by the proposed price.
• Multiply by 100 to express the result as a percentage.
• Compare that result with your own chosen target.

Use the calculation as one input to the decision

The calculation relates the ingredient cost in the portion to a possible menu price. It does not account for every expense, guarantee profitability, choose your food-cost target, or choose your final price. Review the recipe math alongside the other information and priorities you use to run your restaurant, then make the final pricing decision for your operation.
