The 80/20 Rule: How it Works & How to Apply it In Your Life

Ever heard the story about peas?

Legend has it that Italian engineer Vilfredo Pareto noticed something peculiar about the peas growing in his garden. Vilfredo recognized that approximately 20% of his pea plants were yielding 80% of the pea crop.

The engineer inside got the best of him, and he expanded this concept to macroeconomics, where he observed 80% of Italian wealth was and still is controlled by 20% of the population. He realized that this rule could be applied to all aspects of life, and it’s now considered the Pareto Rule, or what you might call – The 80/20 Rule.

Simply put, the 80-20 rule states that 80% of your outcomes (outputs) come from 20% of causes (inputs). Using the pea example, 80% of the peas eaten from the garden came from 20% of the plants.

In business, the law states that you should focus your efforts on identifying the most productive 20% (clients, channels, sources of income) and spend 80% of your time there. You can use the popular 80/20 rule can be used to fit any facet of life, however, and many use it to help them strategize how they spend their time with regards to:

How to Apply The 80/20 Rule in Your Life

Typically regarded as an economic philosophy, you can apply the 80/20 rule to anything in your life. Whether you’re looking to make more money, get in better shape, or expand your relationship with loved ones – Pareto’s law works.

Here are just a few examples of how to apply it!


Have you ever heard the sentiment that hitting your health goals boils down to your eating habits? In fact, you may have heard that the key to getting a six-pack abdomen is 80% diet (hmm, wonder where this comes from).

Or what about the fact that it is estimated most endurance athletes operate in the moderate heart rate/effort zone 80% of the time? Needless to say, health is an area where you can apply the 80/20 rule to your life and see amazing returns!

Here are some ideas to help you use the 80/20 rule with health:

  • Instead of a complete diet overhaul, adjust you’re eating habits 12 out of 15 meals, or 80% of the time!
  • Runner? Spend 80% of your time running at a moderate rate, 20% of your time pushing yourself.
  • Looking to lift a lot of weight? Invest 80% of your effort moving moderate weight with perfect form!

Business, Wealth & Investing

Ever heard of the 80/20 budget?

In essence, the concept is very simple, spend 80% of your money on things you need, enjoy, and bills – just make sure you’re paying yourself first with the other 20%! Wonder where the concept of the 80/20 budget came from?

When it comes to applying Pareto’s law to your life, you can most greatly benefit from it in terms of business and money.

Case in point, in 2020, when the pandemic hit, I had a friend who owned an exterior remodeling business make a pivot in how he approached his business.

Completely unaware of the Pareto principle, he said, “80% of my money comes from gutters and roofs,” he continued and elaborated, stating, “And 80% of my headaches come from siding and window projects.”

His solution: He focused almost all of his marketing and production efforts on roofs and gutters.

After recognizing that most of his profit came from just two of his services, he doubled down using the 80/20 rule and was able to get rid of 80% of his problems while focusing more energy on the highest producing services. This is just one example of how applying the 80/20 rule to your business or investing can result in better outcomes!

Examples of applying the 80/20 rule in business, wealth & investing:

  • You’re a self-employed hairstylist, and you recognize that 80% of your profits come from the color and upkeep jobs, not the cheap hair cut customers. It would be best if you doubled down on color and upkeep
  • In reviewing your investment portfolio, you recognize that 80% of your investing efforts are only resulting in 20% of your returns. Now, you know where to take your money – to the 20% producing 80% of your returns!
  • You recognize that nearly 80% of your sales come from 20% of your sales team in a leadership role. You now have two options: Double down on the 20% crew OR focus tons of effort in helping the 80% who seem to be struggling. At that point, you can determine whether it is a skill or will… or if perhaps parting ways makes more sense!
  • Follow the 80/20 rule to spending money – 80% of your money goes to bills and spending, at least 20% to saving… not food delivery apps 


You are who you associate with, for better or worse. The 80-20 rule is a great way to distance yourself from toxic relationships and increase time with those positive relationships you truly enjoy.

As it relates to Dunbar’s Numbers, we can only efficiently carry about 150 relationships at a time. You can absolutely know more people, but the minute you start spending time with one person – there is most likely a loss in time somewhere else, with someone else.

Know this and wanting to spend the most time with the most important people in your life, be sure to 80-20 your relationships. Identify where you want to spend 80% of your social and family time by figuring out the top 20% of people you enjoy the most!


Most people have to break their bad habits before they can start seeing the results they covet in their lives. What better way to do this than to apply the 80/20 rule to your daily habits!

Even though we mostly think we are in control of our lives, it is estimated that almost half of what we do is on autopilot. Nearly 45 of what you do daily is the result of habit – for better or worse. Knowing this, you might have some new habits you would like to introduce, but you want to be mindful that you don’t overdo them!

Examples of applying the 80/20 rule to your daily routines & habits:

  • Spend 80% of your time on your top 20% priorities
  • Figure out what 20% of possessions give you 80% of the most happiness, get rid of the rest
  • Perhaps you work from home, and you find that you waste 80% of your time, and you’re only productive 20% of the day – now it’s time to fix it!
  • Spend 80% of your day not on your phone, 20% or even less on your phone
  • Analyze hobbies and where you spend 80% of your time, ask if they’re where you really want to spend your time
  • Decide what brings you the most joy. Focus on that.
