You can then add this amount to your initial deposit to find the total value of your CD at maturity.

How much interest will I earn on a CD?

The interest earned from a CD depends on its annual percentage yield (APY), compounding frequency and term length. These factors make it important to compare rates and terms when choosing the best CD for you. 

To illustrate how these factors affect your earnings, take a look at how APY affects the ending balances of a one-year CD in the table below:

APY Interest Earned on $1,000 after One Year Total Ending Balance
1.85% $18.50 $1,018.50
4.50% $45.00 $1,045.00
5.00% $50.00 $1,050.00
5.50% $55.00 $1,055.00
6.00% $60.00 $1,060.00

Understanding your CD calculator results

To understand your CD interest calculator results, it’s important to know that CD rates are expressed as an annual percentage yield (APY). A CD’s APY refers to how much interest it will earn during a year while accounting for compounding.

By contrast, annual percentage rate (APR) is used for credit cards, personal loans and other debt-related products and refers to how much interest is charged in a year while accounting for the monthly interest of the debt account. The APY more accurately represents a CD’s net gains, which is why CDs use APY instead of APR rates.

The CD’s future value is the total amount you can expect your CD investment to grow by the end of its term, assuming you do not make an early withdrawal, for which you may have to pay a penalty.

CDs pay higher interest rates than even some of the best savings accounts but have less liquidity. Additionally, the APY is fixed for the CD’s entire term, providing you with guaranteed earnings at maturity.

For example, if you deposit $2,000 into a three-year CD with a 5.0% APY, you can expect the following results:

Deposit Interest earned at the end of year one Interest earned at the end of year two Interest earned at the end of year three Total interest earned Future value of CD
$2,000 $102 $108 $113 $323 $2,323

As you can see, when the CD reaches maturity, the total amount within the account will be $2,323.

CD terms to know

To understand your calculated results for a CD, you must know the following terms:

Considerations when opening a CD

Before you open a CD, you need to evaluate several factors to determine whether doing so would be a good choice for meeting your financial goals.

Term length

A CD’s term length is how long you leave your money in the account without making withdrawals. When you open a CD, you agree to leave your deposit untouched until the end of its term, which is when it matures. CD term lengths vary, so consider a CD’s term before opening an account. 

Interest rates

Banks offer varying APYs for CDs. While long-term CDs usually pay the highest APYs, some short-term CDs, such as three-month CDs and six-month CDs, offer competitive rates today. It’s best to choose a CD that pays the most interest for the term you desire.

Minimum deposit

Some banks and credit unions require minimum deposits to open a CD. Consider whether you can afford to deposit at least the minimum required amount without needing access to the funds for the CD’s term.

Early withdrawal penalties

Under federal law, banks and credit unions must assess a minimum penalty of seven days’ simple interest when you withdraw funds from a CD early. However, the government doesn’t set a maximum penalty, and many financial institutions assess additional penalties. 

In some cases, you might forfeit the interest you earned while your money remains in the account when you withdraw early. Carefully assess whether you can afford to leave your money in a CD for its entire term.

FAQ: CD Calculator

How much will a $10,000 CD earn in five years?

How much a $10,000 CD will earn in five years depends on its APY. For example, depositing $10,000 into a CD that pays 4.5% APY will earn $2,518 in five years for a final balance of $12,518. By contrast, depositing $10,000 in a 6% interest CD will earn $3,489 in five years for a final balance of $13,489.

How do you calculate interest on a CD?

To calculate interest on a CD, you can use the following formula: Interest = P x r x t

This formula will allow you to see the future value of your CD based on your initial deposit, the interest rate and the CD term.

If you’d rather not calculate this by hand, you can use our CD calculator to receive results in a second.

How much can you make on a 5% CD?

How much you make on a 5% CD depends on your initial deposit and the CD’s term length. For example, if you deposit $1,000 in a CD with a 5% APY and a term of one year, you’ll earn $50 for a final balance of $1,050. If you deposit $1,000 in a 5% CD with a term of two years, you’ll earn $105 in interest for a final balance of $1,105.

What if I put $20,000 in a CD for five years?

If you put $20,000 in a CD for five years, you’ll need to understand that the account is illiquid, meaning you won’t be able to access your funds for the five-year term. As long as you’re comfortable with that and have an established emergency fund, how much you earn depends on the APY offered by the bank. 

For example, if the APY is 1.86%, you’ll earn $1,948 in interest in five years for a future value of $21,948. By contrast, if you deposit $20,000 in a CD with an APY of 6.00%, you’ll earn $6,977 in interest for a future value of $26,977.

Is it worth putting money into a CD?

Investing money in a CD is worthwhile if you can afford not to touch the funds during the CD’s term, have a conservative risk profile, are nearing retirement or are saving for a specific financial goal. 

If you are less risk-averse, are young and have a long time to save, you might be better off investing your money in stocks or bonds because of the potential to earn higher returns.

How do you apply for a CD?

Many banks allow you to apply online, in person at a bank branch or over the phone. You must provide a valid government-issued ID and a U.S. residential address. Choose whether you want to leave the interest in the CD or receive it periodically. Once you have chosen and submitted your application, you must sign some documents and make your deposit.

How much will a $100,000 CD earn in one year?

How much $100,000 in a one-year CD will earn depends on its APY. For example, many online banks and credit unions offer CDs with an APY of 5.5%. In this case, $100,000 in a one-year CD would earn $5,500.
