Understanding How Money Can Grow Over Time
Compound interest is a powerful concept that can help your money grow exponentially over time. Simply put, compound interest is interest that is earned not only on the principal (the amount of money you originally invested), but also on the interest that is earned over time. This means that your money can grow faster and faster as time goes on.
ğŸ’¡How to Calculate Your Earnings
To calculate compound interest, you'll need to use a formula that takes into account the principal, the interest rate, and the length of time that the money is invested. The formula is:
where: A = the total amount of money at the end of the investment period P = the principal (the amount of money you originally invested) r = the annual interest rate (as a decimal) n = the number of times interest is compounded per year t = the length of time in years that the money is invested
Using this formula, you can calculate how much your investment will be worth at the end of the investment period.
ğŸ’¡How Small Amounts Can Add Up Over Time
One of the amazing things about compound interest is that even small amounts of money can add up to big returns over time. For example, if you invest just $50 a month at a 6% interest rate for 20 years, you would have over $24,000 at the end of the investment period. That's the power of compound interest at work!
ğŸ’¡A Fun and Visual Way to Understand Compound Interest
The tree method is a fun and visual way to understand how compound interest works. Imagine that your initial investment is the trunk of a tree, and each year the interest you earn is a new branch that grows out from the trunk. As time goes on, the tree gets bigger and bigger, and the branches grow more and more numerous. This is a great way to visualize how your money can grow over time through the power of compound interest.
