Whether you’re investing or parking your money in a high-yield savings account, either activity can work for you and help you build wealth. This occurs through compound interest, which is a powerful tool and can potentially generate thousands of dollars over the years.
It is, however, essential to understand how compounding interest works so you can take advantage of it. Knowing when it can hurt you is also necessary for your financial well-being.
Compound Interest Generates Income
Compound interest occurs when the interest earned on an investment or savings account is added to the balance. Future interest is calculated on the new amount. The process is repeated over each compounding period. This results in your investment or savings growth rate increasing in value.
In other words, compound interest is generating interest on interest.
For example, if you invest $20,000 at an annual interest rate of 5 percent, you will earn $1,000 the first year, resulting in a balance of $21,000. The following year, interest is calculated on the new balance of $21,000. This results in an interest gain of $1,050.
This continues with each period’s interest being added to the balance. The result is graduated growth.
What Are Compounding Interest Periods?
Compounding interest periods are intervals when interest is added to the balance. Interest can be compounded annually, semiannually, quarterly, monthly, daily, and continuously.
It can be compounded on any basis as determined by the financial instrument.
Interest may accrue daily, but is only credited monthly or whatever the period is. Only when the interest is added to the balance and credited does it start earning additional interest for you.
Compound Versus Simple Interest
The main difference between compound interest and simple interest is how they are calculated.
Simple interest is based solely on the principal throughout the investment or saving period. It has linear growth. But compound interest is calculated on both the initial principal and the interest that has accumulated over the period. This results in exponential growth.
Types of Compound Interest
Investment accounts and credit card companies often use compound interest. Some banks and credit unions also use compound interest for savings accounts.
It’s important to choose financial accounts that use compound interest.
Types of Simple Interest
Some savings accounts and certificates of deposit (CDs) use simple interest.
Some loans, including personal loans, student loans, and auto loans, also use simple interest. These loans are typically paid back over a short period, so the financial institution doesn’t have to charge additional interest to earn money.
Advantages of Compound Interest
Compound interest will accelerate momentum to help you reach financial goals. Your earnings are reinvested for you, so your money grows automatically.
It’s an easy way to boost your earnings without taking on additional risk. It allows you to earn interest both on your original investment and the interest earned.
Left alone, compound interest is an effective tool in retirement planning.
Disadvantages of Compound Interest
According to Thrivent, compound interest can also work against you if you have debt. Credit card issuers often use compound interest against consumers.
If you carry a balance, the interest charged to you will be compounded. This leads to a higher balance and sends you into deeper debt.
Taking Advantage of Compound Interest
Time is critical when it comes to compounding. The earlier you start, the more opportunities you allow for your money to grow. Compounding requires some patience because you must leave it alone and let it work for you.
There are ways to help compounding do its job.
Start Investing or Saving Early
With all investments, the earlier you start, the more you’ll accumulate. Even small contributions made consistently over a long period will help your compound interest grow your money.
Always Reinvest Returns
The Fiducient Advisors recommend taking advantage of compound interest by reinvesting your earnings. Resist the urge to withdraw them and allow your investments or savings to compound uninterrupted.
This applies to interest, dividends, and capital gains. Some investment vehicles, like dividend reinvestment plans, automatically reinvest.
Never Too Late or Too Early to Start Compounding
Compound interest isn’t only beneficial for the young; it can be used to boost savings and investing at any age.
In your 20s and 30s, you have time for growth. But you’ll still have meaningful yields if you start redirecting discretionary income into high-yield savings accounts or investments.
For those older than 60, short-term compounding, like reinvesting dividends, can enhance financial security.
The point is to take advantage of compounding at any age.
Use Compound Interest to Strengthen Finances
Compound interest is a powerful tool in financial planning. It works whether you’re starting to save and invest or trying to catch up for retirement.
By reinvesting and saving consistently, you can take advantage of compound interest and put your money to work for you. This will grow your nest egg.
