What did Einstein say about compound interest?
The underlying wisdom of the adage derives from the power of compounding, what Albert Einstein called the eighth wonder of the world. “He who understands it, earns it. He who doesn't, pays it,” he is said to have said.
Albert Einstein once said “Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it”. While some people question whether the quote was in fact from Einstein, the power of compound interest is unquestionable.
Compounding is the process whereby interest is credited to an existing principal amount as well as to interest already paid. Compounding thus can be construed as interest on interest—the effect of which is to magnify returns to interest over time, the so-called “miracle of compounding.”
Compounding interest, however, does that interest calculation more than once over a period of time. In a year, it might be calculated monthly, weekly, quarterly, and so on. Each time it is calculated, the interest earned gets added, so that the next time the interest is figured, the amount of money is now larger.
Compound interest is when you earn interest on the money you've saved and on the interest you earn along the way. Here's an example to help explain compound interest. Increasing the compounding frequency, finding a higher interest rate, and adding to your principal amount are ways to help your savings grow even faster.
He wasn't known for his investing abilities, but he did identify the most amazing mathematical revelation known as 'compound interest'. Albert referred to it as the eight wonder of the world.
Do you know the Rule of 72? It's an easy way to calculate just how long it's going to take for your money to double. Just take the number 72 and divide it by the interest rate you hope to earn. That number gives you the approximate number of years it will take for your investment to double.
For continuous compounding interest, you'll get more accurate results by using 69.3 instead of 72. The Rule of 72 is an estimate, and 69.3 is harder for mental math than 72, which divides easily by 2, 3, 4, 6, 8, 9, and 12. If you have a calculator, however, use 69.3 for slightly more accurate results.

Invest early and consistently
The earlier you start investing, the more likely you are to become a millionaire. It's that simple (thanks, compound interest)! If you start putting away $300 a month beginning at age 25, assuming an 11% rate of return, you could be a millionaire by age 57.
Why is compound interest so powerful?
Compound interest causes your wealth to grow faster. It makes a sum of money grow at a faster rate than simple interest because you will earn returns on the money you invest, as well as on returns at the end of every compounding period. This means that you don't have to put away as much money to reach your goals!
Compound interest describes the ability to earn not only interest on the principle but also reinvested interest on the interest. “ We started at a very early age in rolling the snowball down,” Buffett said in 1999. “ The trick is to have a very long hill, which means either starting very young or living ...
On the positive side, compound interest makes the return on investments (e.g. savings, retirement accounts) grow quicker and more substantially over time. On the negative side, it makes debt (e.g. credit cards) grow quicker and more substantially over time.
Paying more frequently, such as weekly or daily, won't make any difference unless you're paying more. There's no magic trick to stopping compound interest.
Compound interest makes your money grow faster because interest is calculated on the accumulated interest over time as well as on your original principal. Compounding can create a snowball effect, as the original investments plus the income earned from those investments grow together.
Albert Einstein thought so. Seeing your money grow thanks to compound interest can be just as amazing as seeing the Great Wall of China or the Colosseum. He said, "Compound interest is the eighth wonder of the world. He who understands it, earns it; he who doesn't, pays it."
There is an often-told story that when Albert Einstein was once asked what mankind's greatest invention was, he replied: "Compound interest." There's even one claim that Einstein called compound interest the "8th Wonder of the World."
From the moment he entered the United States in 1933, Albert Einstein was under constant surveillance by the FBI, which was alarmed by his advocacy of peace through world government and his support for Zionism. This file chronicles the daily activities and findings of agents assigned to Einstein over the years.
The Rule of 69 is a simple calculation to estimate the time needed for an investment to double if you know the interest rate and if the interest is compound. For example, if a real estate investor can earn twenty percent on an investment, they divide 69 by the 20 percent return and add 0.35 to the result.
Final answer:
It will take approximately 15.27 years to increase the $2,200 investment to $10,000 at an annual interest rate of 6.5%.

4 | P ( 1 + R 100 ) 4 | P ( 1 + R 100 ) 4 − P |

Basic compound interest
For other compounding frequencies (such as monthly, weekly, or daily), prospective depositors should refer to the formula below. Hence, if a two-year savings account containing $1,000 pays a 6% interest rate compounded daily, it will grow to $1,127.49 at the end of two years.
What is the compound interest formula, with an example? Use the formula A=P(1+r/n)^nt. For example, say you deposit $5,000 in a savings account that earns a 3% annual interest rate, and compounds monthly. You'd calculate A = $5,000(1 + 0.03/12)^(12 x 1), and your ending balance would be $5,152.
