Albert Einstein Gave Us The Principle Of Compounding Interest

       Today I want to talk to you about the great scientist Albert Einstein. He revolutionized the 20th century. When we begin manned missions to the stars in 100 years or so, his principles will guide the whole endeavor.

       Unbeknownst to many, Einstein made a foray into the world of finance and economics. He pioneered the concept of compounding interest. Let me give you a simple example as follows with a growth in the account of 10% per year:

2021:   Account balance  $100

            Interest earned:   $  10

            Ending balance:   $110

2022    Ending balance:   $121

2023    Ending balance:   $133.18

2024    Ending balance:   $146.41

2025    Ending balance:   $161.05

2026    Ending balance:   $177.16

2027    Ending balance:   $194.88

2028    Ending balance:   $216.32

        In this theoretical exercise, you have doubled your money in 7 years. The real world is different. We have inflation. You might not be guaranteed a 10% average return each year unless you invest in a truly excellent mutual fund or have a brilliant fund manager like Ray Dalio handling your amount. You also might want to make contributions to the account each year. With all these variables you would need a very good computer program to predict the results. The principle still will work then.

       In a country like the US, Canada, Spain, etc., if you put money in a savings account, you might get 2% in annual interest payments. A good fund manager can give you an average return of 10% a year. In inflation-ravaged countries, you must play an entirely different game.
