Portion Calculator

Portion Calculator – Scale Recipe to the Right Serving Size

The portion calculator changes the number of servings in a recipe to your desired amount. Enter the original ingredients and serving size, select the desired serving size – the calculator scales all amounts automatically.

When is a portion calculator useful?

• Halving a recipe – The cooking recipe is for 4, but you're cooking for only 2
• Increasing a recipe – You want to make a cake for 20 people instead of the original 8
• Party cooking – Scale the recipe for 50 people for parties
• Diet tracking – Calculate exact gram amounts for a specific serving size

Scaling Factor

The scaling factor is calculated simply:

Factor = Desired serving size / Original serving size

For example, if the original recipe is for 4 and you want to make it for 10, the factor is 2.5 and all ingredients are multiplied by 2.5.

Tips

• Note that baking time does not always scale directly with the amount – two cakes bake almost as fast as one
• For spices, scaling usually works well, but check according to taste
• Baking powder and yeast – In large quantities, the ratio may be slightly smaller than direct scaling
