Learn what compound interest is, and how to open an account
Albert Einstein once famously referred to compound interest as the eighth wonder of the world. Compound interest works when you earn an interest return on your savings, and instead of withdrawing it, you reinvest it to allow your savings to grow even more. In simple terms, you earn interest on your interest. As your savings grow from the past interest earned, you receive a higher return each year due to the compounding effect, resulting in exponential growth.
You don’t need to be a Nobel Prize winner like Einstein to benefit from the power of compounding. To take advantage of compound interest, you can open a compound interest account and make the most of this remarkable phenomenon. Before signing up, it’s essential to research and understand the details of the account and how compounding can work for you.
How to Open a Compound Interest Account

A compound interest account is a type of account that allows you to earn interest or another form of return on your savings, enabling your money to grow over time. You have the option to open a compound interest account with a bank or an investment broker.

Steps Required to Open a Compound Interest Account
Each company has its own specific process for opening a savings account with compound interest. Here’s a general overview of how it works and what you should consider when comparing your options.
Step 1: Determine the type of compound interest account you need. Decide if you want a guaranteed return without the risk of losing money, which could be offered by high-yield savings accounts, money market accounts, and certificates of deposit (CDs) from banks. Or, if you’re willing to take on a higher compounding rate with the possibility of short-term losses, consider a brokerage account to invest in bonds, mutual funds, REITs, and stocks. Some companies may offer a combination of both approaches.
Step 2: Compare costs, fees, and incentives. Be aware of various fees, such as annual account fees, minimum balance fees, trading commissions, and expense ratios, as they can impact your overall earnings. Look for companies that keep these fees as low as possible and also check for any incentives offered when you open a new compound interest account.
Step 3: Compare services. Different companies offer different services, so consider what you want from your compound interest account in terms of product selection, access to various investment accounts, compound interest calculators, access to brick-and-mortar branches, customer service options, and support from financial advisors.
Step 4: Sign up for an account. Once you’ve chosen where to open your compound interest account, you can formally sign up. You’ll need to provide personal contact information, employment details, and your tax ID number (usually your Social Security number) for identity verification to comply with government regulations. The application process duration varies based on the type of account, ranging from potentially an hour for bank accounts to several days for brokerage investment accounts.

Understand the Basics
If you want to begin earning compound interest, the first step is to choose the type of account that suits your needs. There is a wide variety of compound interest accounts available. You have the option to select very safe and straightforward accounts that require minimal research. Alternatively, you may decide to explore more complex and higher-risk accounts that offer the potential for higher returns. Here, we will focus on the basic and secure compound interest accounts and provide an overview of what they entail.
High-Yield Savings Accounts
High-yield savings accounts are bank accounts that offer a higher interest rate compared to regular savings accounts. The best high-yield savings accounts provide a competitive return while charging minimal fees, often with no fees at all. Savings accounts are secure, and you cannot lose money in them. Additionally, they offer convenient access to your funds whenever you need them. If you’re interested in learning more about high compound savings interest accounts, check out our roundup of the best high-yield savings account rates.
Money Market Accounts
Money market accounts are a type of bank deposit account. Usually, they require a higher minimum balance compared to high-yield savings accounts, or else you may be subject to a monthly fee. The advantage of money market accounts lies in their higher interest rates. By depositing more money, you can earn more compound interest using these accounts. The return on money market accounts is guaranteed, and you don’t run the risk of losing money. Additionally, you have the flexibility to withdraw funds whenever you need them.
Certificates of Deposit (CDs)
When you open a Certificate of Deposit (CD) account, you get to choose the duration of the CD, known as the “term.” The term can vary from as short as one month to several years. Throughout this agreed-upon term, you will earn a guaranteed compound interest rate on your CD balance. It’s important to note that your CD balance is insured, ensuring that it won’t decrease.
However, if you need to withdraw your money before the CD’s term is complete, you will incur a penalty. This penalty could result in the forfeiture of some or all of the interest earnings and even a portion of your initial deposit. Despite the penalty for early withdrawals, CDs typically offer higher interest rates compared to other bank deposit products, providing greater potential earnings in exchange for less immediate access to your funds.
Bonds and Bond Funds
A bond is a financial instrument where you lend money to a government, company, or organization for a specific period. During this time, you receive interest payments, and at the end of the bond term, you get your initial investment back.
Bonds carry more risk and require more research compared to bank deposit accounts. To ensure safety, it is crucial to check the issuer’s credit rating. If the issuer encounters financial difficulties, there’s a possibility they might not fully pay the interest or return your initial investment. To minimize risk, consider bonds from reputable issuers like the U.S. government or well-established companies. Bond rating agencies assign letter grades to indicate the financial stability of different issuers.
If you wish to access your money before the bond’s term ends, you have the option to sell the bond to another investor through your investment platform. However, keep in mind that you might receive less than what you initially paid if interest rates have increased since your purchase.
For those who prefer not to conduct extensive research themselves, an alternative is to invest in a bond fund. In a bond fund, a professional investor creates a portfolio of various bonds, enabling you to earn compound interest through this approach.
Mutual Funds
Mutual funds pool the funds of multiple small investors to form a large investment portfolio. A professional investor oversees the management of the portfolio and makes decisions on investments. Each mutual fund has its specific investment objectives. For instance, an income mutual fund emphasizes safer investments like bonds, while a growth mutual fund prioritizes higher-earning but riskier investments like stocks.
It’s important to note that mutual funds carry more risk compared to bank accounts. There is a possibility that some investments may not perform well, resulting in a decrease in your fund’s balance. Despite this risk, mutual funds offer higher earning potential than bank accounts. If you’re considering long-term investments, mutual funds have the potential to earn more compound interest for you.
Types of High-Risk Compound Interest Accounts
These compound interest investments can earn more than the basic options if you want to push for a higher return. But, be warned, they also require more research and you have a higher risk of losing money.
REITs
Real Estate Investment Trusts (REITs) are investment funds that focus on real estate properties. When you invest in a REIT, you join forces with many other investors, and the REIT utilizes the pooled funds to acquire a diverse portfolio of properties. As an investor in a REIT, you earn a share of the profits generated from rent collected and property sales.
REITs offer a convenient way to benefit from compound interest in the real estate market without the need to personally buy and manage properties, which can be both labor-intensive and expensive. Many REITs are publicly traded, allowing you to sell your shares to another investor and cash out whenever you prefer.
However, it’s essential to consider that some REITs, known as non-traded REITs, might lock your investment for an extended period, potentially spanning several years. This longer-term commitment should be carefully evaluated before investing in non-traded REITs.
High-Yield Bonds
In the world of bonds, the interest rate tends to be higher for riskier investments. High-yield bonds, also known as junk bonds, offer a higher face interest rate, leading to increased earnings from compound interest. However, these bonds come with an elevated risk of default. As a result, you might only receive partial interest payments, and in the worst case scenario, if the issuer goes bankrupt, you could lose your initial investment.
High-yield bonds are classified as those with a Standard & Poor’s credit rating of BB+ or lower, indicating their higher level of risk. It’s important to carefully assess the risk-reward trade-off before considering investments in high-yield bonds.
Cryptocurrency
Cryptocurrencies, such as Bitcoin and Ethereum, are digital currencies that operate in a decentralized manner without government control. If you choose to invest in cryptocurrencies, there is a possibility of making profits if their prices increase. Additionally, some cryptocurrencies employ a staking system, where you can lock up your owned cryptocurrency temporarily and receive an interest return in the form of more cryptocurrency.
However, it’s essential to be aware that investing in cryptocurrencies comes with very high risk. While there is potential for significant rewards, there is also the possibility of substantial losses. It is crucial to carefully consider the risks before deciding to invest in cryptocurrencies.
Dividend Stocks
Companies issue stocks as a means of raising funds. When you purchase stocks, you become a partial owner of the company and may have the opportunity to share in future profits. Companies can use their earnings to reinvest and continue growing or distribute profits to shareholders through dividend payments. Dividend stocks are from companies that pay a higher dividend rate, which typically includes larger, more established, and profitable companies. Smaller companies and those in growth phases are less likely to pay dividends.
For those interested in earning compound interest from dividend stocks, it’s important to research each company’s past dividend rate and ensure that the company is expected to remain profitable to continue paying dividends. To find some investment ideas, you can explore top dividend stocks. Alternatively, if you prefer not to conduct this research yourself, you can look for a mutual fund that focuses on dividends to handle the investment decisions for you.
Alternative Investments
Alternative investments refer to those that exist outside the traditional financial markets. These can encompass a variety of assets, such as hedge funds, private equity funds, commodities, artwork, and farmland. Unlike conventional investments like stocks and bonds, alternative investments carry higher risk levels and often demand more extensive research.
Certain alternative investments, like hedge funds, may require you to qualify as an accredited investor. However, the potential for these investments to yield high returns is also a possibility, making them appealing to some investors. It’s crucial to carefully consider the risks and conduct thorough research before delving into alternative investments.

Factors That Affect How Much Interest You Earn
Calculating your compound interest earnings allows you to assess whether you are making progress toward your financial goals. Several factors influence the amount of interest you will earn, including: [List the factors.]
Account Balance
As the saying suggests, having money to invest is essential to generate returns. When you deposit more money into a compound interest account, you earn a higher annual return. This forms the basis of interest compounding, where your savings grow progressively over time as you reinvest the earned interest. Consequently, the amount you earn each year increases as your savings continue to compound.
Interest Rate
The account interest rate indicates the amount you will earn annually on your balance. When exploring how to open a compound interest account, it is important to find one that offers a competitive interest rate. Additionally, stay informed about market and economic conditions, as interest rates can fluctuate, impacting the amount of interest you earn each year. Periodically check for better deals from other companies to ensure you are getting the most favorable terms for your savings.
Compounding Frequency
Compounding frequency refers to how often your account starts earning interest on previous earnings. Accounts can compound annually, quarterly, monthly, or even daily. The more frequent the compounding schedule, the more interest you can earn per year. This is because the account begins to generate a return on your past earnings at a quicker rate.
If you are interested in opening a daily compound interest account, our review of the best CD rates highlights many options that offer daily compounding.
Account Fees
If you owe fees for your compound interest account, they will be deducted from your balance. Therefore, the more you pay out in fees, the less you keep for your annual interest earnings for compounding.
FAQs
What Is Compound Interest?
Compound interest is the interest that accumulates on both your initial deposit and any previously earned interest or investment earnings. For instance, if you place $10,000 in a savings account with a 5% annual interest rate, you will earn $500 in the first year, resulting in a total balance of $10,500. In the second year, your earnings will be $525, as you now make a return not only on the initial $10,000 but also on the $500 interest earned in the first year.
Over time, this compounding effect allows your savings to grow progressively, leading to an increase in the amount of money you earn through compound interest.
How Does Compound Interest Work?
Compound interest works by steadily increasing the value of your money in a bank or investment account. Initially, you deposit your money into a compound interest account that specifies the annual interest rate. Your balance then begins to grow by this compound interest amount. In the subsequent years, your balance, along with the interest earnings from the previous year, continues to grow further based on the specified interest rate.
The power of compound interest lies in its exponential nature, as your savings grow over time. As your account balance increases, you earn more interest, leading to even greater growth in your savings. This compounding effect allows your money to multiply progressively, resulting in substantial earnings over the long term.
Who Benefits From Compound Interest?
Compound interest is advantageous for savers and investors. To benefit from it, you need to have extra money that you can deposit into a compound interest account. This account will then generate a return, which will gradually grow your savings. As your account balance increases, the interest earned compounds, allowing you to earn more money each year.
On the contrary, compound interest can be detrimental for individuals in debt. If you owe interest on your debt, this amount gets added to your outstanding balance. As a result, the more debt you accumulate, the more you will be charged in interest each year, leading to an increase in the total amount you need to repay.
Are Compound Interest Accounts Safe?
There are several compound interest accounts that are considered safe, such as high-yield savings accounts, money market accounts, and CDs. In these accounts, banks provide a guarantee for your return, and you are shielded from market losses. However, safe compound interest accounts generally offer a lower interest rate compared to riskier options.
For those looking to earn higher returns, there are riskier investment opportunities like dividend stocks, mutual funds, and REITs. By investing in these options and seeing positive performance over time, you can increase your yearly earnings through compound interest. It’s essential to note that along with the potential for higher returns, these riskier investments also carry the possibility of losses.
How Is Compound Interest Calculated?
Calculating compound interest for one year involves multiplying your initial amount by one plus the interest rate. For instance, if you start with $1,000 and earn a 5% interest rate, your growth with compound interest would be $1,000 x (1 + 5%) = $1,000 x 1.05 = $1,050.
For multiple years, use the formula: starting principal x (1 + interest)^n, where n represents the number of years. For example, in the same scenario, if you keep the $1,000 for five years, it would grow to $1,276.28.
This formula applies to annual compounding. If compounding occurs more frequently, the calculations become more complex. To determine how much you will earn over time with different compounding frequencies, you can use an online compound interest calculator.
