Enter the activity or effort into the calculator to determine the result or outcome based on the 90/10 rule.

90/10 Rule Formula

The following formula can be used to calculate the 90/10 rule:

R = 0.9 * A

Variables:

• R is the result or outcome
• A is the activity or effort

To calculate the result or outcome based on the 90/10 rule, multiply the activity or effort by 0.9. This suggests that 90% of the results or outcomes are determined by this portion of activities or efforts.

What is a 90/10 Rule?

The 90/10 rule is a principle in business and personal development that suggests 90% of the results or outcomes are determined by 10% of activities or efforts. This rule is also known as the Pareto Principle, named after the Italian economist Vilfredo Pareto, who observed that 80% of Italy’s wealth was owned by 20% of the population. The principle has since been applied to various fields, suggesting that a small proportion of causes lead to a large proportion of effects.

How to Calculate 90/10 Rule?

The following steps outline how to calculate the 90/10 Rule using the formula: R = 0.9 * A.

1. First, determine the value of A (activity or effort).
2. Next, multiply A by 0.9.
3. Finally, calculate the result or outcome (R).
4. After inserting the value of A and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

A (activity or effort) = 100
