What is Compound Interest? Rich Mom Answers

Compound Interest
Compound Interest helps your money grow faster.

Today’s topic? Compound interest. But first, let me introduce myself. 

Hi! I am a mom focusing on inspiring those who are ages 30 and under. I want my child and you to have a life moving toward financial understanding starting at an early age so that you can have the best life possible. 

Money is a tool to help you have the best life possible. It gives you power to pay for your needs, and as yours grows, it allows you the ability to pay for your wants. As your money continues to grow, it allows you the ability to pay for more wants. 

As you improve your financial literacy, you need to grow your knowledge of financial terms. 

So, let’s dive into our first question… 

What is simple interest?

Simple interest is the money that is paid for allowing someone to hold and use your money when it is paid at a flat rate. In other words, the interest is paid on the principal that you deposit, not on any interest that builds up.

What is an example of simple interest? 

Here is an example of simple interest: 

If you borrowed $100, and the interest rate on the loan were 10%, the interest that you would have to pay would be $10. You calculate that like this: $100 X .10 = $10.  

Now…

What is compound interest?

Compound interest is when the original money being held (the principal) earns interest, and then the next time that interest is paid, interest is paid on the principal (which you would have left in the account) plus the previously earned interest. The next time interest is paid, the interest would be paid on the principal, plus the two previous eaarnings. This pattern continues, which means that the interest is being paid on interest. In effect, interest is being paid on more and more money. So, the interest is compounding. 

Why is compound interest better?

Compound interest is better than simple interest because it makes more money faster than simple interest. Put another way, it grows your money faster. It does that because is interest paid not only on the principal but interest paid on previous interest, too. 

When is compound interest good?

It is good when interest is compounded when you are the receiver of that interest. So, when you receive it on something like a high-yield savings account, or on bonds, it’s good for you. It is bad when you have to pay it. This is like when you pay interest on a loan or a credit card. 

What did Albert Einstein say about investing?

Reportedly, Albert Einstein called compound interest the eighth wonder of the world. 

When is simple interest better than compound interest?

Simple interest is better than interest that is compounded when you are borrowing money. 

It’s the reverse when you are depositing and investing money. 

Are compound interest accounts safe?

All investments have their risks, and various investments have various amounts of risk. Compound interest works for both guaranteed and non-guaranteed investments. 

How can I earn compound interest?

You can earn it in a variety of ways. 

Looking for ways to earn interest that is compounded? Try:

  1. High-yield Savings Account
  2. Money Market Funds
  3. Bonds
  4. Bond Funds
  5. ETFs
  6. Dividend Stocks

What is the easiest way to earn compound interest?

Perhaps the simplest way to earn compound interest is to open a high-yield savings account.

Which investments pay compound interest?

  • High-yield savings accounts
  • Dividend stocks
  • REITS
  • Bonds
  • Bond Fonds
  • ETFs
  • Money Market Accounts

Which is better? Compounded monthly or annually?

For a given rate, it is better to receive interest compounded monthly rather than annually. So, if you receive 4% interest compounded monthly, it is better than 4% compounded annually. 

However, interest rates for annual compounding are ofen higher than interest rates compounded monthly. 

Does a 401K get compound interest?

Yes. How frequently depends on the specific account. It could happen daily, monthly, or annually. 

What type of interest earns you more money?

Compound interest earns you more money than simple interest. This is because, not only is interest paid on the principal (which is the money that you deposit), it is also paid on the previous interest paid, as long as you leave all of the money in the investment instrument.

How did Benjamin Franklin describe compound interest? 

Benjamin Franklin described compound interest by saying, “Money makes money. And the money that money makes, makes money.”

Benjamin Franklin demonstrated his belief in this powerful method of growing money by leaving the equivalent of $4000 each to Pennsylvania and Massachusetts. The money could not be fully accessed for 200 years. When the money could be fully accessed, Pennsylvania’s money had grown to $2 million, and Massachustt’s money had grown to $4.5 million.
