How the recipe scaling calculator works

Enter the original yield:
Add the number of servings, portions, or pieces the original recipe makes.

Enter the desired yield:
Add how many servings or portions you want to make.

Scale one ingredient:
Enter one ingredient amount to see the adjusted amount. Apply the same scale factor to the rest of the recipe.

Why recipe scaling matters

A recipe scaling calculator helps resize recipes accurately when cooking for more or fewer people.

This is useful for baking, meal prep, party portions, family meals, leftovers, catering, batch cooking, freezer meals, and changing recipe yield.

What your result means

Your result shows the scaled ingredient amount, recipe scale factor, adjusted yield, amount per serving, and estimated cook time guidance. Use the scale factor for each ingredient in your recipe.

Frequently asked questions

How do you scale a recipe?

Divide the desired yield by the original yield. Then multiply every ingredient by that scale factor.

How do I scale a recipe from 4 servings to 6 servings?

Divide 6 by 4 to get 1.5. Multiply each ingredient by 1.5.

Do cooking times scale the same as ingredients?

Usually no. Ingredient amounts scale mathematically, but cooking time depends on pan size, food thickness, oven temperature, and batch depth.

Should spices and salt scale exactly?

Not always. Salt, spices, extracts, yeast, baking soda, and baking powder may need small adjustments after scaling.
