True hydration, counting the flour and water carried inside your starter.

All tools

True hydration — the calculator counts the flour and water carried inside your starter. Learn how main-dough and true hydration differ.

Enter the flour, water and starter weights and this works out true hydration — the total water divided by the total flour, including the flour and water carried inside the starter.

It reports the hydration of the formula you entered. It does not judge whether that hydration is right for your flour or your handling.
