Buffett’s journey – a case study

My previous blog post was on the importance of saving in the early part of life. Saving early gives investments the time they need to grow. Now, I use the example of a well-known billionaire – Warren Buffett – to emphasize a few key points.

As of the end of 2015, Buffett’s wealth was estimated at somewhere between $60 and $70 billion. Is Buffett’s example a realistic one to use for the average person? It is. Not in the “everybody can be a billionaire” sense, which is obviously not true. Buffett however, was not born into exceptional wealth, nor did he become a billionaire overnight. He became focused on amassing wealth at an early age, did jobs and earned money for offering his investment skill as a service to others. He was uncommonly frugal, as described in his various biographies. As his earnings grew, so did his savings. At some point, the compounding of his wealth outgrew any salary or fees he would earn. My guess is that his investment return was already more than his salary/fees when he was in his 30s. Buffett is 85 now, and the wealth we see today is the result of over half-a-century of compounding at a rate faster than the US stock market’s. His is an extraordinarily executed example of the wealth growth trajectory I described in my earlier post. Persons who can emulate the things he did right even to a limited extent can find financial prosperity.

Here are a few data points on the growth of his wealth (quoted verbatim from the wikipedia page describing Warren Buffett):

  1. By 1950, at 20, Buffett had made and saved $9,800.
  2. In 1956, … Buffett’s personal savings were over $174,000.
  3. By age thirty-five, he was worth $7 million. – from “Buffett-The making of an American Capitalist” by Roger Lowenstein.
  4. Buffett became a paper billionaire when Berkshire Hathaway began selling class A shares on May 29, 1990.
  5. On August 14, 2014, the price of Berkshire Hathaway’s shares hit US$200,000 a share for the first time. While Buffett had given away much of his stock to charities by this time, he still held 321,000 shares worth US$64.2 billion.

Buffett’s net worth vs. his age is plotted below:

And here’s the rate at which his net worth grew over different periods.

Age Rate of growth of net worth
20-26 62%
26-35 51%
35-60 22%
60-84 19%

It is easy to see that Buffett’s wealth grew much more rapidly in his early years. There are two main reasons for this:

  1. When he was young, his wealth was growing from two sources. One was the money he saved from the salary/fees he earned, and the other was his investments. Later on, his savings became insignificant, and the growth of his wealth was due to investments alone.
  2. A skilled investor like Buffett can achieve higher investment return when he is investing only a small amount of money. When investing tens of billions of dollars, one is forced to invest in a lot of different things. The business Buffett likes best might return 50%/yr but the size of such business opportunities is usually small – in the millions, not billions. Buffett commented in an interview: “If I was running $1 million today, or $10 million for that matter, I’d be fully invested. Anyone who says that size does not hurt investment performance is selling. The highest rates of return I’ve ever achieved were in the 1950s. I killed the Dow. You ought to see the numbers. But I was investing peanuts then. It’s a huge structural advantage not to have a lot of money. I think I could make you 50% a year on $1 million. No, I know I could. I guarantee that.” Regardless of whether Buffett can actually achieve 50%, the inverse relationship between investment size and investment return is logical.

My main point here is that early life is a great time to multiply one’s net worth. Even without Buffett’s investment acumen, today a frugal person with a healthy salary can save five figures each year and quickly achieve a net worth of $100,000 in 5-10 years, at which point investment returns start to matter. Buffett went from $9,800 to $174,000 in the six years between age 20 and 26. That was a lot of money in 1956. Today, a person earning $60,000/yr, and saving $18,000 (which happens to be the annual contribution limit for a 401K) can go from $0 to $72,000 in six years by just saving. Saving $18,000 out of a $60,000 salary isn’t easy, but it’s doable. Investing like Buffett is a lot harder.

Now imagine that the saver, with $72,000 saved, decided to invest in the US stock market (S&P500) for the next fifty years, and achieved not Buffett-like returns, but merely stock market returns. Based on the data here, the index was priced at 44.15 in 1956 (when Buffett was 26) and priced at 1278.73 in 2006 fifty years later. If our saver achieved the same growth as the index has done in the past, then the $72,000 would grow into a little over 2 million. The saver wouldn’t be a billionaire – not even close – but I’ve assumed that the saver saved nothing past the first five years, and I’ve also not taken dividends paid by the S&P500 into account. This saver would be one very prosperous retiree by doing two simple things: saving early and staying invested.

Stories of people who earned little but saved, invested, and retired rich are numerous. But in all fairness, I make it sound easy. While the path outlined is real, it is hard to follow because of human nature. I will talk about pitfalls of investing another day.

Saving dominates initially. Investing later.

One of my friends is a retired investment advisor. In a presentation, he emphasized: Start investing early. He illustrated this with an imaginary example of two people, Amy and Bob. They both get jobs at the same time, and both work for 30 years before retiring. Amy saves and invests $10,000 each year for the first 10 years of her life. She then saves no more but keeps her money invested. Bob, on the other hand, saves nothing for the first 10 years, but saves and invests $10,000 each year from year 11 through year 30. At retirement, Amy, who saved for only 10 years, has more money than Bob, who saved for 20 years. Assuming that investments grow at 8% each year (for simplicity) Amy has $675,212 whereas Bob has only $457,620. This is true even though Bob saved for twice as many years. Moral of the story: Start saving and investing early.
But why does Amy have more? There’s an important insight to be gleaned from understanding why the early years are so important. To answer the why, we must observe the how – how money compounds over time. The charts below show the net worths of both individuals over the years. Net worth is divided into two parts: one part that can be attributed to savings accumulated over the years, and another attributed to accumulated investment income. Cumulative savings and investment income are shown as stacked columns for Amy and Bob in the two charts below.
A few basic observations are presented below:
  1. Amy’s savings start from $0 and grow to $100,000 in the first ten years. Her cumulative savings don’t grow after that. However, her investments continue to grow.
  2. Amy’s investment income is relatively modest in the first ten years. Whereas she saves $100,000, her investment income adds up to a total of $44,866 over ten years. Compare this with the last year of her career, when in that one year alone her investment income is $54,017, more than she earns in the first ten years put together.
  3. Bob saves nothing, and consequently has no investment income in the first ten years. His net worth is zero until year 10. From years 11 through 20, his wealth grows exactly as Amy’s grew in years 1 though 10. But then there is a departure. Bob continues to save, whereas Amy stopped saving after the first 10 years.

Sadly for Bob, he still falls short despite saving for twice as many years. Saving is hard. It involves sacrifice. Why does Bob fall short? This question can be largely answered by looking at year 11. In year 11, Bob saves $10,000. Amy saves nothing. But Amy’s investments earn $12,516. Amy’s investments are growing faster than Bob can save! Amy had a huge head start. Even though her investment income seemed small in the first 10 years, the total pile of savings and investments she built in those early years was enough to outpace Bob. In year 30, Bob’s investment income is $36,610, which isn’t small, but it is well short of the $54,017 Amy’s investments earn that year. For savers, investment income becomes sizeable as they approach retirement, as it should be. After all, in retirement, people expect to be able to live off of their investment income without reducing their net worth very much. After all, who knows how long we are to live.

My friend, the retired financial advisor, lamented that this parents hadn’t invested their money. They had government jobs. They didn’t earn much. They had to save painstakingly to retire.  But despite everything, they retired. They did one key thing right. They saved.


This is a blog on finance and investing (see NO FINANCIAL ADVICE disclaimer below). SciPre is short for Science of Prediction.

We can roughly predict the future if we know the present and have studied the past carefully. As someone said: History does not repeat, but it rhymes. It has long been a quest of mine to understand happiness, the importance of wealth as it applies to happiness, wealth creation, the role of financial markets in wealth creation, and ultimately understanding human behavior well enough to anticipate markets.
