A guide to building wealth through compound interest


Compound interest is the addition of interest to the sum of the principle of a loan or deposit. In other words, it is interest on top of interest. This is how it works. When you invest money, you intend to profit over time. If you leave the money alone plus the interest, compound interest applies the interest rate to the total amount of money earned. Your money builds over time.

Simple interest, however, does not accrue. It's gone once you pay or earn interest for a particular period. It is not added to the next payment period like compound interest.

How it works

If you invest $500 and it earns 10% interest at the end of the year, then after one year, you earn 550$. Meaning the original interest earned is 50$. In the second year, you will earn 600$ additional interest and it will keep accumulating over the years. Imagine living the money untouched for 40yrs it will accumulate 26,500$. How fascinating.
