In addition, you’re going to have a MASSIVE opportunity cost. On average, the stock market goes up 10% each year as I have mentioned but I like to use that 8% number just to be safe. Well, while you’re paying off this debt you’re missing out on extremely valuable time investing in the market. Before we get too far into the weeds, let me first explain what compound interest is. The concept is that when you earn interest in X amount of time, that next time period you’re going to earn interest on the principal AND the interest that you previously earned. Basically you’re double dipping on return on your investments.
The problem though, is that there is substantial doubt he actually said that. For example, let’s say you have an interest rate of 6%. This means it’ll take 12 years for your investment to double. What do the wealthiest and wisest investors have in common?
Compound interest requires that you lock in your money for a longer period to get the most significant benefits. The following table demonstrates the difference that the number of compounding periods can make for a $10,000 loan with an annual 10% interest rate over a 10-year period. 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. The interest payable at the end of each year is shown in the table below.
- It also mitigates a rising cost of living caused by inflation.
- For lower annual rates than those above, 69.3 would also be more accurate than 72.[3] For higher annual rates, 78 is more accurate.
- That’s enough to buy a small island for the birthday celebration, or just about anything else she or her family could want.
- Compound interest is interest added to the principal of your investment so that from that moment on, the added interest also earns interest.
- The longer the investment period, the more you will benefit from compound interest.
- And if I can be quite frank, it’s why broke people are broke and rich people are rich.
Einstein suggests that compound interest can work for you or against you. If you use it to your advantage with your investments, it will make all the difference over the long term. Long term is 30, 40, or more years, not five years. The earning aspect is very, very similar to the example that I just gave you above. That example might seem outlandish but it’s really not. Believe it or not, you can actually save $5K/year with just a few simple tweaks in your daily life.
Investing and retirement
That’s a $27,000 gain — not a negligible sum, but not nearly as impressive as a gain of $155,000. By the end of 10 years, the balance is £2,000 for the simple interest account compared to £2,594 for the compound interest account. This process differs from so-called ‘simple’ interest, which is when interest from previous years is ignored, and the calculation is made only with reference to the original amount. You should always check with the product provider to ensure that information provided is the most up to date. For higher rates, a larger numerator would be better (e.g., for 20%, using 76 to get 3.8 years would be only about 0.002 off, where using 72 to get 3.6 would be about 0.2 off). This is because, as above, the rule of 72 is only an approximation that is accurate for interest rates from 6% to 10%.
For young people, compound interest offers a chance to take advantage of the time value of money. Remember when choosing your investments that the number of compounding periods is just as important as the interest rate. Compound interest benefits investors across the spectrum.
How do interest rates affect investments?
For the first couple years of my investing journey, I really didn’t fully comprehend what he was meaning when he said this. That means at the end of the first year you have a balance of $10,800. Now if you reinvest that $10,800 for 8% you will earn 8.64% in interest the next year, consequences of incorporation separate legal personality giving you a balance of $11,664 at the end of the second year. 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.
Why is compounding important?
In investing, compounding is simply the concept of earning a return on your previous returns. A quick example is that if you invest $1000 for one year at a 10% return you will have $1100 at the end of the year. After earning this $100 you decide that you want to do the same thing for the next year and reinvest your principal ($1000) and return ($100) and earn 10% again. This year instead of earning $100 dollars you earn $110.
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. Don’t do something as boneheaded as what I did where I was treating myself to something that I really shouldn’t have ever done. Even though I paid off the loan, I was lucky to do so. Who knew if something crazy could’ve happened and my job offer was revoked or maybe I had major unforeseen expenses come up that prohibited me from paying my loan off quickly.
