How to calculate 80/20 rule?

To use the 80/20 rule (Pareto Principle), identify your total inputs (tasks, customers, causes) and outputs (results, revenue, effects) in a specific area, then list them from highest to lowest impact to find the "vital few" (around 20%) that generate the bulk of your results (around 80%). You calculate this by ranking your inputs by their contribution, finding the cumulative percentage, and seeing where that 80% mark falls, often revealing that a small portion of your efforts drives most of your success, like 20% of customers bringing 80% of revenue.
