The 70/30 Rule in Decision-Making

The Pareto Principle, also known as the 80/20 rule, is a principle that states that 80% of effects come from 20% of causes. For businesses, the 80/20 rule can help free up time and energy, streamline operations, and increase profitability.

Why Do I Call the 80/20 Rule the 70/30 Rule?

Automating a mindset, behavior pattern, or process is often about simplification. Since the 70/30 rule is already used in marketing, finance, learning, training, time management, and many other areas, I’ve chosen—for simplicity’s sake—to adapt the Pareto Principle to a 70/30 version as well.

The Pareto Principle, or 80/20 rule, describes the common phenomenon that 80% of consequences in a given area come from 20% of the causes. The rule is named after the Italian economist Vilfredo Pareto, who in 1906 observed that 20% of Italy’s population owned 80% of the wealth.

In business theory, this phenomenon is used as a basis for pricing and market strategies—particularly when industry patterns suggest that 20% of customers account for 80% of revenue. By focusing efforts on the 20% of customers who generate the most revenue or profit, businesses can achieve the greatest financial gain.

How to Apply the 70/30 Rule:

  1. Identify Key Tasks
    Determine which tasks or decisions have the potential to produce the most significant outcomes—whether related to revenue, efficiency, customer satisfaction, or other critical metrics.
  1. Allocate Resources Accordingly
    Invest a significant portion of your time, energy, and resources (70%) into these high-impact tasks. These are the areas where you can make the biggest progress.
  1. Minimize Low-Impact Tasks
    Reduce the time and resources spent on tasks that have lesser impact (30%). While these tasks may still be necessary, they shouldn’t receive a disproportionate amount of attention.

The key takeaway is that not all tasks or decisions are equally important. Some have a greater influence on your goals and outcomes than others. By prioritizing the top 30% of tasks that matter most, you can maximize your overall effectiveness and achieve better results with less effort.
