Formula
Scaled amount = amount × target ÷ base.
Portion cost = sum of ingredient costs ÷ portions. Food cost percent = portion cost ÷ menu price × 100. The recipe cost calculator uses the costs you type, not a grocery index.

Recipe calculator for scaling and cost per portion
This recipe calculator scales one ingredient by the ratio of target portions to base portions. Switch to cost and it becomes a recipe cost calculator: four ingredient costs divided by the portion count, and a food-cost percent if you enter a menu price. The recipe scaling calculator uses the same factor on every ingredient. Dengaro arranges equipment financing for kitchen equipment.

How it works
The scale factor is target portions divided by base portions.
Scaled amount equals the ingredient amount times target portions divided by base portions. Eight portions scaled to twenty is a factor of 2.5. An ingredient of 2 becomes 5. The cost mode adds up to four ingredient costs. Four, six, three, and zero dollars is a $13.00 batch. Eight portions is $1.63 each. Leave the menu price at zero and the food-cost percent stays blank. Type a menu price and the percent is the portion cost divided by that price. Apply the same factor to every ingredient on the card. This page holds one ingredient at a time in the scale mode so the factor stays obvious.

Example
Scale 2 units from 8 portions to 20.
The factor is 2.500 and the scaled amount is 5. In the cost mode, $4 + $6 + $3 is $13.00 for the batch and $1.63 for each of 8 portions. Change one cost and the portion cost moves with it.

Tips
Scale weights, not pinches.
A factor of 2.5 on a teaspoon of salt is fine. A factor of 2.5 on a 'pinch' is not. Write the original recipe in weights before you scale a large batch. Yield loss, such as trimming, is not in the factor.

Equipment
The batch size is what the mixer has to hold.

Important questions
Know what to expect.
Does the recipe scaling calculator change bake time?+
No. It changes amounts. A larger pan can need a different time and temperature. That judgment stays with the baker.
How many ingredients can the recipe cost calculator hold?+
Four cost fields. Add a subtotal of the rest into one field if the recipe is longer. The page sums whatever you enter, including zeros.
What if the menu price is zero?+
The portion cost still shows. The percent stays off until you enter a price, because dividing by zero is not a food cost.
Is this a nutrition calculator?+
No. It scales a quantity and adds costs. It does not compute calories or allergens.
