$585,000 or $487,000. Same $500 a month, same 30 years on an assumed 7%. The only difference is one rule a beginner can follow in 10 minutes. That is rule six. There are 10. Each one comes with something Warren Buffett actually wrote or said with the source in the description and one number that shows why it matters.
By the end, you will have a short checklist you can hold your own investing against. These are principles, not product picks and not financial advice. Rule one, two sentences. If you cannot explain an investment in two plain sentences, you probably do not understand it well enough to own it. Warren Buffett called this your circle of competence.
In his letter to shareholders for 1996, he wrote that what an investor needs is the ability to evaluate selected businesses. And then he added the key line, the size of that circle is not very important. Knowing its boundaries, however, is vital for a beginner. This is good news. You do not need to understand everything.
You need to know what you do not understand and stay away from it. Here is why it matters in numbers. An investment you do not understand can fall by 60% before you even realize what went wrong. And a 60% fall needs a 150% gain just to get back to where you started. The maths of losses is not symmetrical.
Losing is fast. Recovering is slow. For most beginners, staying inside the circle means something very simple. A broad lowcost fund that owns a wide slice of the market is easy to explain in two sentences. A complicated product with a story you cannot repeat is not a quick test before any investment.
Can you say what it owns, how it makes money, and what could make it fall? If any of those three answers is fuzzy, that is your circle telling you something. The most common beginner mistake here is buying something because a friend, a video, or a forum made it sound obvious. obvious to them is not the same as understood by you.
One thing to do this week, write down in plain words what each investment you own actually is. If one line ends up empty or vague, that is the first thing to learn about or to reconsider. 10 years of growth and almost nothing to show for it. That can happen when you pay too much. In his letter to shareholders for 2008, Buffett wrote that long ago, Ben Graham taught him this.
Price is what you pay. Value is what you get. Here is a simple example of what that means. Imagine a great company whose profits grow by 7% a year for 10 years. Over that decade, profits almost double. Now imagine you bought its shares when the market was so excited that you paid 40 times its yearly profit.
10 years later the excitement is gone and the market pays a more ordinary 20 times profit. The business did everything right. Profits almost doubled. But because the price you paid was so high, your shares are worth about the same as when you bought them. 10 years of good business and roughly zero gain.
That is the difference between price and value. A great company is not automatically a great investment. It depends on what you pay for it. For beginners, there are two practical lessons. First, be careful with whatever everyone is excited about right now because excitement is usually already in the price.
Second, a regular monthly investment in a broad fund means you never put all your money in at one excited moment. Some months you pay more, some months you pay less. Over time, the average evens out. Which of these rules do you already follow? Type one for rule one, two for rule two. We read the comments and reply every morning.
The beginner version of this mistake is buying only after something has already been on the news for weeks. By then, much of the good news is usually in the price. One thing to do this week, before buying anything, ask what you are paying for it compared with what it earns or owns. If you have no way to answer, a broad fund bought a little at a time takes that question off your shoulders.
$19,000 after 10 years, $76,000 after 30. That is the same $10,000 left alone at an assumed 7%. Buffett's most famous line about time comes from his letter to shareholders for 1988 when Birkshere owns parts of outstanding businesses with outstanding managements. He wrote its favorite holding period is forever.
Notice the condition which is often left out when people quoted outstanding businesses with outstanding managements. Forever is not a promise to hold anything no matter what. In his letter for 2016, he made clear that Burkshere has made no commitment to hold any of its marketable securities forever.
The real lesson is about time, not about never selling. $10,000 at 7% becomes about $19,700 in 10 years. In 30 years, about 76,000. The last 10 years add more than the first 20 combined because growth builds on growth. The enemy of that curve is constant activity. Every trade can bring costs, taxes in many countries, and a new chance to make an emotional mistake.
Beginners often feel that doing something is better than doing nothing. With long-term money, doing nothing on purpose is frequently the best decision available. The beginner version of this mistake is checking the account every day. Daily prices move for reasons that have nothing to do with a 30-year plan.
And every check is a new invitation to react. One thing to do this week, decide how often you will look at your long-term account. Once a month is plenty for most people. Once or twice a year is enough for the plan itself. Up 50% then down a third. That takes you exactly back to where you started. In his letter to shareholders for 1986, Buffett wrote about fear and greed.
He called them contagious and said they will keep breaking out in the investment world at unpredictable times. Then he wrote the line that became famous. His aim was simply to be fearful when others are greedy and greedy only when others are fearful. It is important to read that carefully. Buffett also wrote that he never tries to predict when these moods will arrive.
This is not advice to time the market or to wait for a crash before investing. Nobody can do that reliably. For a beginner, the useful part is the first half. Do not catch the crowd's excitement. Here is what chasing does in numbers. Someone sees an investment that has already gone up 50% and buys because it feels safe now that everyone is talking about it.
Then it falls by a third which is a normal fall for something that rose so fast. 1.5 * 2/3 is 1. They are back to exactly where they started after all that excitement. The steady alternative is boring on purpose. a fixed amount on a fixed day every month. Whether the headlines are cheerful or frightening, the crowd's mood stops being part of your plan.
The beginner version of this mistake usually starts with a screenshot of somebody else's gains. It feels like evidence, but it shows one person at one moment, often at the top. One thing to do this week, write down the one rule you will follow when an investment you do not own is suddenly everywhere.
For many people, that rule is simply to keep their monthly plan unchanged. 90% that is the share Buffett suggested for a very lowcost S and P500 index fund in his own instructions for his family. In his letter to shareholders for 2013, Buffett described the instructions he left for money that will go to his wife.
Put 10% in shortterm government bonds and 90% in a very lowcost S and P500 index fund. 20 years earlier in his letter for 1993, he made the same point for ordinary investors. He wrote that by periodically investing in an index fund, the know nothing investor can actually outperform most investment professionals.
Nothing is not an insult. It describes most of us, people who do not study businesses for a living. For that person, owning a broad slice of the whole market removes the need to pick winners. and it is easy to explain in two sentences which brings us back to rule one. This channel does not recommend any specific product and rules, taxes, and available options differ from country to country, but the principle in Buffet's own words is clear, broad, simple, very low cost.
Have you ever owned an index fund? Type one for yes, two for not yet. Both answers are useful here. The beginner version of this mistake is owning many funds and believing that makes you diversified while several of them hold the same large companies. One thing to do this week, look at what your funds actually hold.
Two broad funds that overlap almost completely are not twice as safe. They are one fund paid for twice. $98,000. That is what 1% a year can cost over 30 years. Here is the number from the start of this video. $500 a month for 30 years grows to about 585,000 at 7%. With a 1% yearly fee, the money grows at about 6% instead and ends at about $487,000.
The fee costs about $98,000. more than half of everything that was put in. Buffett tested this idea with real money. He made a 10-year bet from 2008 to the end of 2017. On one side, a lowcost fund that owned the 500 large American companies in the S and P500. On the other, five groups of hedge funds chosen by professionals with much higher fees.
In his letter for 2017, he reported that the index fund gained about 126% over the decade. The five groups of hedge funds gained between about three and about 88%. Not one of them won. Finding your own number takes a few minutes. Look for the yearly percentage on your fund, sometimes called the expense ratio, and any advisor fee on top.
then multiply by your balance. That is roughly what you pay each year and it compounds against you. The beginner version of this mistake is ignoring a fee because it looks small next to the return in a good year. The return changes every year. The fee is taken every year, good or bad. One thing to do this week, find the yearly cost of each investment you own and write it next to the name.
If you cannot find it, that is a good question to ask the provider. 60%. That is what a 30% fall becomes when you invest with borrowed money at 2:1. In his letter to shareholders for 2017, Buffett listed four times when Burkshere's own stock fell sharply by between 37 and 59%. Then he wrote this. This table offers the strongest argument I can muster against ever using borrowed money to own stocks.
He also wrote that there is simply no telling how far stocks can fall in a short period and that even small borrowings can unsettle your mind during a fall. Here is the arithmetic. Say you invest your own $10,000 plus 10,000 borrowed. The market falls by 30%. Your 20,000 becomes 14,000, but you still owe the full 10,000.
Your own money has gone from 10,000 to 4,000. A 60% loss from a 30% fall. And to recover from 60%, you need a 150% gain. Borrowing makes good years better and bad years catastrophic. For a beginner, the rule is simple. Invest only money that is truly yours and that you will not need soon. Borrowing to invest does not always look like a loan.
It can be a margin account, a product that promises double the daily return, or putting investments on a credit card. One thing to do this week, check whether anything you own uses borrowed money directly or inside the product. If you are not sure, the product description usually says so, and that is worth reading slowly.
18%. Buffett said he does not know how to earn that, so he would not pay it either. At the Burkshere Hathaway annual meeting in 2020, Buffett was asked what ordinary people should do with their money. He said that if he owed money at 18%. The first thing he would do with any money he had would be to pay it off.
He added that he does not know how to make 18%. Here is what that looks like. A credit card balance of $5,000 at 22% costs about $1,100 a year in interest. Paying it off is in effect earning 22% on that money with near certainty. The plan in this video assumes seven with no certainty at all. So for a beginner, the order matters.
Clear highinterest debt first, then start investing or at least do both while sending every spare dollar to the debt. Which rule do you think you need most right now? Type the number 6, 7, or 8. We read the comments and reply every morning. The beginner version of this mistake is investing with one hand while carrying a card balance with the other because investing feels like progress and paying off debt does not.
Mathematically, the debt payment is usually the better investment. One thing to do this week, list every debt with its interest rate highest first. That list tells you where the next spare dollar should go. 8 months. That is how much a single $3,000 emergency can delay a beginner's plan when there is no cash set aside.
This rule is less about Buffett's words and more about his habit. Birkshshire Hathaway has kept large amounts of cash for decades. so that it is never forced to sell at a bad moment. For a person, the same idea is called an emergency cushion. Here is the number. on a plan of $500 a month at 7%. A $3,000 car repair paid by selling investments followed by three months of no contributions while the checking account recovers pushes the first $100,000 back by about 8 months.
The repair cost 3,000. The damage to the plan was much larger. A small cushion in a separate savings account changes that the repair comes out of the cushion. The investments stay untouched and the monthly plan keeps running. How much? It depends on your income, your family, and how secure your job is.
Many people start with a few hundred, then one month of essential costs, then more over time. The goal is that a normal surprise never forces you to sell long-term investments. The beginner version of this mistake is treating the cushion as lazy money and investing it to make it work. The cushion is working.
Its job is to protect everything else. One thing to do this week, open a separate savings account if you do not have one and set a small automatic transfer into it, even 20 or $50. $ 32 shares. That is what 5 months of the same $500 can buy when the price drops and recovers. In his letter to shareholders for 1997, Buffett used a simple example about hamburgers.
If you expect to keep buying hamburgers for years, you should hope beef prices go down, not up. The same is true for anyone who will be a net buyer of stocks for years to come. Lower prices mean your regular money buys more. Here is a fivemonth example. You invest $500 every month. The price is 100, then 80, then 50, then 80, then 100 again.
Your $2,500 buys 32.5 shares. At the final price of 100, they are worth $3,250. The worst month when the price was 50 did the most work for you. This does not mean you should wait for a fall before investing. Nobody knows when one will come. It means that when a fall does come, a beginner who keeps buying on schedule is often better off than one who stops.
Money you need soon is different and should not depend on the market at all. The beginner version of this mistake is stopping the monthly plan during a fall because buying feels wrong when prices are dropping. That is exactly the moment the fixed amount buys the most. One thing to do this week, write one sentence about what you will do the next time the market falls by a third.
If the answer is keep the plan running, the cushion from rule 9 is what makes that possible. So, which of the 10 rules is hardest for you to follow? Type the number 1 to 10. We read the comments and reply every morning. Before we wrap up, a quick look at how this lesson was made. This channel is run by a small independent team.
Every number in this video comes from our own spreadsheet using the assumptions you heard. Every quote from Warren Buffett was checked against a public source and those sources are listed in the description with the year of each letter. AI tools help us draft the script and the narration is an AI generated voice.
This channel is not affiliated with Warren Buffett or Burkshere Hathaway. So here are the 10 rules, one line each. One, stay inside what you understand. Two, price is what you pay, value is what you get. Three, think in decades, not days. Four, do not catch the crowd's mood. Five, for most people, keep it broad and cheap.
Six, watch the fees. Seven, never borrow to invest. Eight, pay off expensive debt first. Nine, keep a cushion outside the market. 10, if you are buying for years, falling prices help. All numbers here are illustrations, not promises. And here is the surprising part. Not one of these 10 rules asks you to be smarter than the market.
Every one of them asks you to do less. Fewer bets, fewer fees, fewer decisions made in a hurry. That is what makes them hard and that is what makes them work. The video on your screen now runs rule three and rule 10 for 30 full years, including what happens when the market falls by a third. Watch it next.
