Excel spreadsheets for wall and elevated slab form design - Start at the first tab and read instructions for use. Possibly a bit on the complicated side so if you don't understand it, then you should probably seek professional assistance.

Excellent tool, especially for a big tall pour. Reminds me of why I hired my foundation out. 8-)
I have one coming up I will probably actually use these sheets on - eventually. :) Still working on the bigger house project basement part time.
