Hydration Calculating Spreadsheet

I'm upgrading the site. Please be patient while I break a few things :)



Greetings all,

This link should take you to my Google Docs page with my Dough Hydration calculator spreadsheet that you can down-load and use.  Unfortunately, it does not translate into GoogleDocs format at all well so you will need Excel to use it.

You can enter numbers in the cells to the left of the slider bars or you can use the slider bars to adjust the values.  Using the TAB key between entries takes you to the next entry cell.

If you have a recipe that you want to scale up or down, the Yellow cell in the right hand panel is where you enter the required dough mass.  The scaled results appear in the chart bars.  If you dont require the starter mass to be scaled, there is a check box that will hold it constant.

The hydration calculations are done for Total Flour Weight (TFW) ie the content of the starter is taken into account.  The salt content is fixed at 1.8%.

Hope you find it useful and that the system works.

Any feed-back, particularly high praise, will be appreciated.

Thank you for taking the time to help so many!


 Thank you for making this available. I look forward to trying it out when I bake this weekend.


I spent hours tyring to convert my measurements to metric and then to weights!  This is awesome....

Thanks for this, will try it out in day or two when trying new loaf.



I can't think of a better complement than what Pattycom states "You Rock"!!!  

I work with numbers daily, so when I get home I'm not too interested in working with numbers again. So, your very handy, dandy hydration spreadsheet is a welcome hiatus from the toiling numbers game.

I belong to a beginner's sourdough baking group and I'd love to share this & the starter spreadsheet with them. I will direct them to your blog. Who knows, maybe they will join this group too.  If you have a problem with sharing these to the group, let me know soon.  Thanks so much for all your work and sharing.

Happy Baking,


It is reward enough to feel that my efforts are appreciated.


Thanks so much, I'm sure the group members will appreciate these.  Hope they will leave you many positive complements.  Mary
