Bonds can make interest for a varying amount of time, depending on the type of bond. Typically, bonds make interest for the entire term of the bond, which can range from a few months to 30 years or more.
The length of time a bond makes interest is determined by its maturity date. A bond's maturity date is the date when the bond issuer repays the face value of the bond to the bondholder. This is usually the same date when the bond stops making interest.
There are different types of bonds, each with its own interest payment schedule. For example, zero-coupon bonds don't make regular interest payments, but instead, the interest is added to the face value of the bond and paid at maturity.

Types of Bonds
Bonds can be a great way to earn some extra income, and there are several types to choose from.
Treasury bonds, also known as T-bonds, are backed by the US government and offer a fixed interest rate. They typically have a long maturity period, ranging from 10 to 30 years.

Corporate bonds, on the other hand, are issued by companies to raise capital. They often have a higher interest rate than Treasury bonds to attract investors.
Municipal bonds are issued by local governments and organizations to finance public projects. They are tax-free, which can be a big advantage for investors in higher tax brackets.
High-yield bonds, also known as junk bonds, are issued by companies with lower credit ratings. They offer a higher interest rate to compensate for the higher risk.
Zero-coupon bonds don't make interest payments during the bond's life, but instead, the investor earns the interest as a lump sum at maturity.
Interest Earning Period
EE bonds accrue interest monthly, but interest is compounded every six months. This means you'll earn interest on interest, which can add up over time.
If you purchase an EE bond, you'll start earning interest immediately, but the interest won't be compounded until six months later. For example, if you buy an EE bond in January, you'll begin accruing interest in January, which will compound twice a year in January and July.
Here's a breakdown of how interest accrues and compounds for different purchase dates:
Keep in mind that if you redeem your EE bond within the first five years after purchase, you'll forfeit the last three months' interest.
Current and I Bonds

The U.S. Department of the Treasury currently sells two types of savings bonds, the EE and I series. Both series have different interest rates, which are either fixed or change with inflation.
The EE series has a fixed interest rate that is set twice a year, on May 1 and November 1.
If you buy EE bonds in January, you will begin accruing interest in January, which will compound twice a year in January and July.
If you buy EE bonds in late January, you may not receive your first interest payment until July.
If you buy EE bonds in February, you'll receive interest in February and August.
The interest on EE bonds is compounded semiannually, which means it's added to the principal every six months.
If you redeem your EE bonds within the first five years after purchase, you will forfeit the last three months' interest.
Here's a rough idea of when interest is paid on EE bonds, depending on the purchase month:
Keep in mind that you cannot cash in your EE bonds for one year after purchasing them.
What's No Longer Earning Interest?

Savings bonds from series A, B, C, D, E, F, G, H, J, and K, as well as all Savings Notes, no longer earn interest.
If you hold one of these bonds, it's time to cash it in. EE and HH bonds, on the other hand, can still earn interest, but only if they meet certain criteria.
For EE and HH bonds, you must check the issue date to see if they're still earning interest. EE bonds earn interest for 30 years from the issue date, and HH bonds earn interest for 20 years.
Don't try to cash your savings bonds outside the United States, as this is not allowed.

Bond Maturity Period

The maturity period of a Series EE savings bond is a total of 30 years from the issue date. This period consists of an original maturity period and one or two periods of extended maturity, which vary depending on the issue date of the bond.
If you cash in your Series EE bonds within the first year of purchase, you won't receive any interest at all. And if you cash them in within the next four years, you'll forfeit the final three months of interest.
You'll have to wait 20 years or more for your bonds to double in value, depending on the prevailing interest rate environment and the bonds' maturity date. This waiting period can be as long as 20 years to double in value and 30 years until they reach maturity.

Maturity Dates for What?

Maturity dates for Series EE bonds vary depending on when they were purchased. The government guarantees that your money will double in value within 20 years, but the time it takes for the bond to reach full maturity can be different.
In the 1980s, maturity dates for EE bonds were as short as eight years, and from March 1993 to April 1995, they were 18 years. The Treasury Department may shorten maturity dates if interest rates continue to rise.
Here's a historical breakdown of maturity dates for EE bonds:
EE bonds will stop accruing interest after 30 years at the date of maturity.
Factors Affecting Maturity Period
The prevailing interest rate environment is the most significant factor determining when Series EE bonds are able to mature. This means that interest rates play a huge role in how quickly your bonds will grow in value.
High interest rates cause EE bonds to increase in value more quickly, resulting in them doubling in value by an earlier date. Conversely, low interest rates lead to a longer time for EE bonds to double in value.

You can use the Rule of 72 to get an idea of how long it will take for your bonds to double in value. This rule divides the number 72 by the interest rate you're earning, giving you the number of years it will take for your money to double.
Here's a rough estimate of how long it will take for your bonds to double in value at different interest rates:
Taxes also play a crucial role in the maturity period of your bonds, as they can whittle away up to one-third of your growth depending on your tax bracket.
Redeeming Bond
You can redeem your Series EE savings bond at any time, but the waiting period varies depending on the issue date.
For bonds with issue dates on or before January 1, 2003, you can redeem them six months after their issue date.
Bonds with issue dates on or after February 1, 2003, have a waiting period of one year after their issue date.

Interest on a bond accrues and becomes part of the redemption value, so you'll get the interest earnings you've accumulated over time when you redeem your bond.
The Secretary of the Treasury may not call Series EE bonds for redemption prior to final maturity, so you can hold onto them until they reach their maturity date if you want to.
If you cash in your Series EE bonds within the first year of purchase, you won't receive the final three months of interest as an early-withdrawal penalty.
Bond Issue and Accrual
If you purchase a Series EE savings bond with an issue date of May 1, 2005, or thereafter, the fixed rate of interest is determined by the Secretary or their designee, and it's established for the life of the bond.
The fixed rate of interest is announced by the Secretary or their designee on May 1 and November 1 of each year, and it's effective on the first day of the month of the announcement.
The most recently announced fixed rate applies only to bonds purchased during the six months following the announcement, or for any other period of time announced by the Secretary.
Issue Dates Prior to 1995

If you purchased a Series EE bond in the 1980s, you might be surprised to know that it matured in as little as 8 years.
The maturity dates for EE bonds varied greatly from the 1980s to the mid-1990s. For example, bonds issued from May 1981 to October 1982 matured in just 8 years.
Here's a breakdown of the maturity dates for EE bonds issued during this time period:
As you can see, the maturity dates were quite short during this time period.
With Issue Dates of May 1, 2005, or Later
If you have a Series EE savings bond with an issue date of May 1, 2005, or later, the fixed rate of interest is determined by the Secretary, and it's established for the life of the bond.
The fixed rate is set by the Secretary or their designee, and it's announced on May 1 and November 1 of each year. The effective date of the rates is the first day of the month of the announcement.

The fixed rate applies to bonds purchased during the six months following the announcement, unless the Secretary announces a different rate for the extended maturity period.
If you redeem a bond with an issue date of May 1, 2005, or later, less than five years following the issue date, you'll face an interest penalty. This penalty reduces the overall earning period from the issue date by three months.
How Does a Bond Accrue Interest?
EE bonds accrue interest monthly, but it's compounded every six months. This has been the method used by the U.S. Treasury since May 2005.
You can use the TreasuryDirect website's savings bond calculator to calculate the interest you've earned if you purchased paper bonds before then.
The interest rate for Series EE savings bonds is set each year on May 1 and November 1.
Here's a breakdown of when interest is compounded for EE bonds purchased in different months:
- If you buy EE bonds in January, interest compounds in January and July.
- If you buy EE bonds in late January, you may not receive your first interest payment until July.
- If you buy EE bonds in February, you'll receive interest in February and August.
If you redeem your EE bonds within the first five years after purchase, you'll forfeit the last three months' interest.
