Compare original and desired servings.

2
Enter desired servings
Use the number of people you are cooking for.
3
Multiply the ingredients
Apply the factor to each ingredient, then adjust seasoning.
What does this tool do?
Recipe scaling multiplies every ingredient by the same factor. This calculator handles the arithmetic and shows the factor, so you can apply it to the rest of the ingredient list.
The Formula
Factor = Desired servings ÷ Original servingsFrequently Asked Questions
Can I halve a recipe?
Yes, but eggs and leavening are easier to weigh. Halve the weight of an egg rather than trying to split it by eye.
Why does cooking time not scale?
A larger batch changes the surface-to-volume ratio and pan depth. Keep the temperature and check doneness rather than multiplying time.
