Compound interest might sound innocuous, but it can be the right tool to grow your wealth exponentially. It can be used for different financial assets, such as retirement savings, emergency funds, or stock market investments, to accelerate growth with time. Regardless of your goals, with enough time, patience, and consistency, compound interest has the potential to turn rags to riches. 

However, you need to understand compound interest to utilize it successfully. Here, we will briefly explain the basics of the concept and some ways to use it and grow exponentially richer. 

Understanding compound interest

Compound interest is the interest earned not only on the initial principal but also on the previously accumulated interest. Unlike simple interest, which is calculated only on the principal amount, compound interest allows earning interest on interest and exponential growth over time. 

The formula might look complex, but it’s easy once you get into it:

Alternatively, you can use the rule of 72 to estimate how long it will take for your principal to double in value. All you have to do is to divide 72 by your rate of return. For example, if you have $1000 that is earning a 6% return, it would double and become $2000 in (72 / 6) years, which is 12 years.

Interest can be calculated over various periods, such as annually, semi-annually, quarterly, or even daily. The more frequent the period, the faster the investment grows.

Bear in mind that compound interest can work against you. While it benefits savers and investors, it goes against borrowings, as the amount owed also grows exponentially over time.

Compound interest pros and cons

Pros

Pros

  • Building long-term wealth: Compound interest benefits savings and investments, as your returns earn returns, and not just your principal;
  • Extra loan repayments: Paying more than the minimum payment on your rate allows you to leverage compounding and save on total interest;
  • Anulls wealth erosion: The exponential growth of this interest allows you to mitigate heightened cost of living or inflation.
Cons

Cons

  • Works against high-interest debt: If you pay the minimum rate on your high-interest debt, compounding interest can make the total debt grow, plunging you into a debt spiral;
  • Complex calculation: Calculating compound interest is much more complicated than calculating simple interest. Luckily, there are online calculators that offset this;
  • Eligible for taxation: Earnings gained this way are taxable (if not stored in a tax-sheltered account). 

The bottom line

Ultimately, compound interest allows you to leverage time and patience to grow your wealth exponentially. Hopefully, we have revealed its secrets to you: calculating the amount you can earn is relatively easy, and you can see for yourself how powerful it can be.

Reinvesting your returns is a universally accepted rule of thumb, and that is precisely what compound interest does; however, remember that it can sometimes work against you. Make sure you do your own research before investing!
