Compound interest simply means you’re earning interest on both your original saved money and any interest you earn on that original amount. Although the term “compound interest” includes the word interest, the concept applies beyond interest-bearing bank accounts and loans, including investments such as mutual funds. Let’s use the same payment scheme as our mortgage example.
- This compounded inflation is up near 20% since 2020!
- Start early and be consistent with your payments to get the maximum power of compounding.
- The Rule of 72 explains the miracle of compounding interest.
- Imagine you invested $1,000 in a fund that provided a return of seven per cent per annum (compounded monthly).
- Then the power of compounding interest can work in your favor.
Long term is 30, 40, or more years, not five years. Basically, anything that grows at an increasing rate has compounding interest. Because compounding has such a huge impact on the outcome of money in the later years, it is crucial that you start saving early.
Compound Interest Investments
And if I can be quite frank, it’s why broke people are broke and rich people are rich. Compounding interest doesn’t care about your race, gender, or age. Compounding interest affects everyone the same, because it depends on time. The first way to calculate compound interest is to multiply each year’s new balance by the interest rate.
- June Greg’s father deposited $6.11 into her account 98 years ago, when she was only two years old.
- The author of How a Second Grader Beats Wall Street, Roth teaches investments and behavioral finance at the University of Denver and is a frequent speaker.
- Einstein was a remarkable physicist and mathematician.
- Because compounding has such a huge impact on the outcome of money in the later years, it is crucial that you start saving early.
- I had taken it for granted that this room full of grown-ups understood what it means when we say, “compound interest is the most powerful force in the universe”.
Einstein didn’t just say that it was pretty cool or good in some way; he said it was the most powerful force. While it is up for debate if Albert Einstein ever said the above quote or called compound interest the eighth wonder of the world, there is truth in the sentiment. Wealth is built by understanding compound interest. Now if you are like most people, at first you might jump on the million dollar deal. But if you break out your calculator and double one penny for 30 days you will be amazed that on day 30 your penny would be worth over $5,000,000.
Did Albert Einstein declare compound interest to be ‘the most powerful force in the universe’?
This compounding effect can be very powerful over a long period of time. People that save early and keep adding to their savings can reap the rewards of compounding. That being said, the market almost never returns anything near the average. Only 6 times in that span has the market returned between 5% and 10%.
Albert Einstein said, “The most powerful force in the Universe is compound interest.” He referred to it as one of the greatest “miracles” known to man. Compound interest is interest added to the principal of your investment so that from that moment on, the added interest also earns interest. What do the wealthiest and wisest investors have in common? They are always smiling, because they are making money every second of the day. The work you need to do in the beginning is often very painful and tiring.
According to Einstein, “Compound interest is the eighth wonder of the world. He who understands it, earns it … he who doesn’t … pays it.” At first this quote might seem like a bit of an exaggeration but the math behind it shows that it is not. For clarification, n will be the same as m if we are just converting nominal interest rate to effective interest rate during a one-year period. If we need to consider more than one year, n will be equal to m multiplied by the number of years we consider. R200 invested with an interest rate of 3% for 2 years (nothing is mentioned about how often the interest accrues; therefore, we assume it is annually). Interest rates are the cost of borrowing money.
Why Albert Einstein loved compound interest
I’ve heard more than a few coaches stress the importance of “practicing the fundamentals” in sports. Growing up, I would hear “even Magic Johnson practices dribbling and passing every day”. The same thing applies here, even if you’ve heard it before, let’s take another look at THE POWER of Compound Interest.
Even with all that fanfare for the topic, I’ve been guilty of neglecting to properly cover when discussing financial literacy. I’ve found I take for granted that I was taught the power behind compound interest at a young age. I was fortunate that I had classes that taught me these lessons as early as middle school, but not everybody is so fortunate. Even so, the truth behind the quote remains rock solid, making it worth considering, no matter who said it first.
Compound Interest: Taking Einstein For Granted.
It is like a snowball rolling down a hill, getting bigger and bigger, year after year after year. Provided, that is, you don’t spend the interest. You have to leave it in your account to allow the compounding effect to gather momentum.

Did Einstein ever remark on compound interest?
From there, you’ll be able to accrue interest on not just your initial $100, but rather, on $105. Compounding periods are the time intervals between when interest is added to the account. Interest can be compounded annually, semi-annually, quarterly, monthly, daily, continuously, or on any other basis. Because compound interest includes interest accumulated in previous periods, it grows at an ever-accelerating rate. In the example above, though the total interest payable over the loan’s three years is $1,576.25, the interest amount is not the same as it would be with simple interest.
Einstein’s Theory of Compound Interest
The total initial principal or amount of the loan is then subtracted from the resulting value. Compound interest is a fairly simple concept that has a huge impact on your investments. The basic rules of success for an investor are a function of your net investment return unearned revenue over time and the length of time you remain invested. Compound interest requires that you lock in your money for a longer period to get the most significant benefits. A statement that the “interest rate is 10%” means that interest is 10% per year, compounded annually.
So you’d earn more money in the last 10 years than in the first 20. This is the logarithmic derivative of the accumulation function. Old Grandpa Rockerfeller the multi-millionaire who preached thrift said something I never forgot. He said, “The 8th wonder of the world is compound interest.” Unfortunately very few people understand the magic of compound interest.
He said, “Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn’t, pays it.” Take the previous example – after five years, you’d not only be earning interest on your original $1,000 investment, you’d also be earning interest on your $403 of interest. In mathematics, the accumulation functions are often expressed in terms of e, the base of the natural logarithm. This facilitates the use of calculus to manipulate interest formulae.
