The purpose of this site is to share different rules of thumb for as many different topics and from as many different contributors as possible. The title “Rules of Thumbs” incorporates this mission with the unconventional spelling of the term “rules of thumb” by adding the “s” after thumb to indicate that the rules of thumb have been generated by many different individuals and collectively are referred to as Rules of Thumbs.
There have been many instances in my personal and professional life that a rule of thumb was simply all I needed, but couldn’t find any. I have begun to contribute all of the rules of thumb that I have used in my career, which has resulted in the content being dominated by business topics in general and venture capital and valuation rules of thumb in particular. Therefore, I hope you will help me build this collection of Rules of Thumbs from which everyone can benefit.
Please email me or use the comments section to submit your own Rules of Thumb. This is meant to be a collaborative environment to create a useful and valuable repository of rules of thumb, “back of the envelope” estimations, and Super Wild Assumptions and Guesses (SWAGs).
To add your own rule of thumb or edit an existing rule, please leave it in the comments field.
Thank you for your help in making this endeavor useful for all. Enjoy!
For your convenience, I have included the Rules of Thumbs for Business and Finance related topics below (they can also be reached via the links to the left).
