Hello All,

I am stuck at understanding shortcuts for estimating large CAGRs:

- eg: a CAGR of 20% for 6 years for let's say $10 M

- eg: a CAGR of 40% for 3 years

- Calculating CAGR, let's say 2006- $6M and 2016 $60M-- how to calculate this mentally?

Thank you very much for your help and suggestions.
