80% of your weekly tasks affect 20% of your future. 80% of grief is caused by 20% of people in your life. 80% of alarms will be set off by 20% of potential causes. 80% of the energy in a combustion engine produces 20% output.

Here are some real world examples of the Pareto Principle you might find interesting: A 2002 report from Microsoft found that “80 percent of the errors and crashes in Windows and Office are caused by 20 percent of the entire pool of bugs detected.” 20% of the world's population controls 82.7% of the world's income.

Example of the Pareto Principle

If an advisory practice has 100 clients, according to the Pareto Principle, 80% of the financial advisor's revenue should come from the top 20 clients. These 20 clients have the highest amount of assets and the highest fees charged.

Here are a few examples of how the 80/20 rule can apply to your life: Your to-do list: You might find that 20% of the tasks on your to-do list contribute to 80% of your productivity, while the other 80% of tasks contribute to just 20% of your productivity.

80/20 Rule Examples

80% of problems originate from 20% of projects. 60% of your distractions come from 40% of sources. 70% of customers only use 30% of software features.

The Pareto Principle illustrates the lack of symmetry that often occurs between the work you put in and the results you achieve. For example, you might find that 13 percent of work could generate 87 percent of returns. Or that 70 percent of problems could be resolved by dealing with 30 percent of underlying causes.

For example, a business may find that 80% of its sales come from 20% of its products and could focus on improving those products to boost sales further. Similarly, an individual may find that 80% of their productivity comes from 20% of their work tasks and could prioritize them to achieve better results.

The 80/20 principle (aka the Pareto Principle) states that roughly 80% of the effects come from 20% of the causes. In other words, a smaller effort can result in a greater output. For example, in marketing, it could be that: 20% of a client's marketing channels generate 80% of the traffic.

An economy is said to be in a Pareto optimum state when no economic changes can make one individual better off without making at least one other individual worse off.

What is an example of Pareto criterion? ›

Example. Consider an economy that contains only one good, which everyone likes. Then every allocation is Pareto efficient: the only way to make someone better off is to give them more of the good, in which case someone else will have less of the good, and hence be worse off.

The Pareto principle states that for many outcomes, roughly 80% of consequences come from 20% of causes (the “vital few”)[1]. A well-observed phenomenon, it creates for a simple and fascinating pattern when you see it at play. 80% of the world's population lives on 20% of its land.

Practical Applications

The Pareto principle can be seen across many sectors of business and within consumerism. Below are a few examples of where it might be found: 80% of the work in a group project is done by 20% of the group. 80% of revenues come from 20% of the products.
