Could it be because pre-retirees don’t understand the basics of the 90/10 rule? For instance, how does it work and when is it right for you? How do you calculate it and what are the risks involved? Here is an in-depth guide into this Warren Buffet’s strategy of investing. Keep reading to stay updated. 

What is the Warren Buffet 90/10 Rule? 

The Warren Buffet 90/10 rule is an investing principle written by the business magnate in his 2013 letter to Berkshire Hathaway shareholders. The rule, initially intended to facilitate the management of Buffet’s wife trust, has since grown turned to be a popular way of growing retirement savings, or even wealth management in estate planning. 

In the letter, the business mogul professes that people preparing for retirement can leverage the methodology to maximize their potential gains, depending on the quality of stock market index funds that they purchase.

How Does It Work?

A typical 90/10 principle is applied when an investor leverages short-term treasury bills to build a fixed income component portfolio using 10% of their earnings. The investor then channels the remaining 90% into higher risk but relatively affordable index funds. 

However, it’s worth noting that the 90/10 split is just a benchmark suggested by the Warren Buffet model. In the real sense, an ideal portfolio for retirement investing should be based on an individual’s tolerance to risk. In other words, you can adjust either sides of the equation provided you’re willing to take the risk. 

Calculating 90/10 Strategy Annual Returns

Calculating your potential returns after retirement savings using Buffet’s rule on stock to bonds is pretty simple if you get it right the first time. So, how do you do it? Let’s look into this portfolio strategy to out the calculation into better perspective. 

An individual with $100,000 who wants to apply Warren Buffet’s advice on investing will mist likely put 90% ($90,000) in an S&P 500 index fund and 10% ($10,000) on annual treasury bills, with a hypothetical yield rate of 4%  The total yield in this case is the sum of the individual allocations multiplied by respective returns. 

Assuming the S&P 500 portfolio yields 10% p.a. the accurate estimate of the total annual returns of the whole portfolio strategy will be:

(0.1 × 4%) + (0.9 × 10%)= 9.4%.

An Example of the 90/10 Strategy

The 9/10 investment advice from Warren Buffet an excellent example of this strategy in real life. He didn’t only give the advice for investing in theory—the estate planning of his wife’s trust use the rule as the principle for estate planning. 

He notes in the will, «My money, I should add, is where my mouth is. What I advise here is certainly identical to certain instructions I have laid in my will. One bequest provides that cash will be delivered to a trustee of my wife’s benefit. (I have to use cash for individual bequests because all of my Berkshire shares will fully be distributed to certain philanthropic organizations over the ten years following the closing of my estate.) My advise to the trustee could not be more simple: Put 10% of the funds in short-term government bonds and 90% in very low-cost S&P 500 index fund. I believe the trust’s long-term results from this policy will be superior to those attained by other investors—whether pension funds, institutions, or individuals—who employ high-fee managers.» 

Variations of the 90/10 Strategy 

Any investment portfolio strategy example that follow’s Warren Buffet’s 90/10 rule takes into account two types of variations, including:

  • Age: older investors might see the need to protect what they already have instead if endlessly exploring other investment options. 
  • Risk tolerance: an investor can change the equations of the rule, depending on their risk appetite, combined with other factors, such as professional 401K advice.

  • Leverage asset allocation funds or diversified stock funds to protect your purchasing power amid long-term, unforeseen inflation

Start Early

Invest in Yourself

As you are watching out for mutual fund recommendations or other stock market tips, don’t forget to invest in yourself, especially during inflations when your options are constrained.
