About this calculator
Egg substitutes do different jobs: binding, leavening, moisture, and structure are not interchangeable. Amounts are starting points and results vary by recipe. The approximate total weight for flax, chia, and powdered replacer includes the added water.
Worked example
calculated with the default values below
Number of eggs to replace 2 eggs · Substitute Ground flaxseed + water Total needed 12 g flaxseed + 90 ml water · Best used for Binding in cookies and pancakes · Amount per egg 1 tbsp flaxseed + 3 tbsp water · Approx. prepared weight, including added liquid 102 g

Frequently asked questions
Are substitutes interchangeable in every recipe?
No. Each option affects binding, moisture, sweetness, and structure differently. Flax and chia can bind dense bakes but do not always replace egg structure in light cakes. Test the specific recipe.
What does approximate total weight include?
For flax, chia, and powdered replacer, it includes the listed water using an approximate 1 ml = 1 g conversion. It is a planning estimate, not a nutrition or recipe guarantee.
