A ‘back of the napkin’ estimate that can be quite accurate. By estimating multiple variables somewhat accurately and both underestimating and overestimating, the variables tend to balance out and result in accuracy within an order of magnitude. This is usually enough to get a general idea of the problem and solution which is useful, similar to dimensional analysis like Big O Notation.
- A famous Fermi estimation is of the Drake equation known as the Fermi paradox
- An estimation aids in understanding similar to projections onto different dimensions

Being able to programmatically generate content for search engine optimization is only useful if you have a lot of keywords you can target (thousands) and pages you can generate to rank for them.
A recent paper analyzed the causal effects of delays in updating unemployment insurance systems written in COBOL. States that used COBOL to process UI claims had a 4.4% decline in total card consumption compared to states that didn’t use COBOL. The author’s Fermi estimate is a $181B decline in real GDP due to COBOL.
