A corporate bond is a loan you give to a company, and the company pays you back with interest

When you buy a corporate bond, you are lending money to a business. The company promises to pay you interest on that loan at regular intervals — usually twice a year — and to return your full investment on a set date called the maturity date. That date might be 5 years away, 10 years away, or 30 years away, depending on the bond.

The interest rate the company offers depends on how risky the loan looks. A large, stable company like a utility or a bank might offer 4% interest. A newer or shakier company might offer 7% or 8% to convince you to take the risk. You do not own a piece of the company — you own a debt it owes you.

Corporate bonds are sold in units of $1,000 each, though you can buy multiple units. You can hold a bond until it matures, or you can sell it to someone else before that date. If you sell early, the price you get depends on whether interest rates have gone up or down since you bought it.

Key Takeaways

  • A corporate bond is a fixed-income investment where you lend money to a company and receive regular interest payments plus your principal back at maturity.
  • The interest rate offered on a bond reflects the company's credit quality — safer companies offer lower rates, riskier ones offer higher rates.
  • Bonds are typically issued in $1,000 units and mature anywhere from 2 to 30 years in the future, depending on the bond.
  • You can sell a bond before maturity, but the sale price will be higher or lower than $1,000 depending on how interest rates have changed.
  • Corporate bonds are riskier than government bonds because companies can default, but they usually pay more interest to compensate for that risk.

How interest payments and maturity dates work

When you buy a bond, the company prints or records a contract that spells out exactly what it will pay you and when. If you buy a $1,000 bond with a 5% interest rate and a 10-year maturity, the company will pay you $50 per year — usually split into two $25 payments, one every six months. After 10 years, you get your $1,000 back.

That interest rate is locked in for the life of the bond. If the company's credit improves or the overall economy changes, the rate does not go up. You keep getting the same $50 per year until maturity, no matter what happens. This is why bonds are called fixed-income investments.

The maturity date is when the company's obligation ends. On that date, you receive your final interest payment plus your $1,000 principal. If you hold the bond all the way to maturity and the company does not default, you know exactly how much money you will have received by the end.

Investment-grade versus high-yield bonds

Investment-grade bonds are issued by companies with strong credit ratings — firms that have a long track record of paying their debts on time. These bonds carry lower interest rates, often between 3% and 6%, because the risk of default is small. Large banks, utilities, and established manufacturers typically issue investment-grade bonds.

High-yield bonds (sometimes called "junk bonds") are issued by companies with weaker credit ratings or shorter operating histories. These companies might be startups, firms in trouble, or businesses in volatile industries. To attract investors despite the higher risk, they offer much higher interest rates — sometimes 8%, 10%, or even higher. The trade-off is clear: more interest in exchange for a real possibility that the company will not pay you back.

Credit rating agencies like Moody's and Standard & Poor's assign ratings to bonds to help investors understand the risk. Bonds rated BBB or higher are generally considered investment-grade. Bonds rated BB or lower are high-yield. These ratings can change if the company's financial condition improves or worsens.

What happens to bond prices when interest rates change

If you hold a bond until maturity, you do not have to worry about price changes — you get your $1,000 back no matter what. But if you want to sell your bond before maturity, the price you receive depends on what has happened to interest rates in the wider market.

Imagine you bought a $1,000 bond paying 4% interest. A year later, new bonds from the same company are paying 6% interest because rates have risen. If you try to sell your 4% bond, buyers will not pay full price for it — they can get a better rate elsewhere. You might have to sell it for $900 or less. The buyer gets a discount because they are accepting a lower interest rate than they could get on a new bond.

The opposite happens when interest rates fall. If new bonds are paying 2% and you own a 4% bond, your bond becomes more valuable. You might be able to sell it for $1,100 or more because buyers want the higher interest rate. This relationship — bond prices move opposite to interest rates — is one of the most important things to understand about bonds.

The risk of default and what it means

Default means the company stops paying you the interest it promised or fails to return your principal when the bond matures. If a company defaults, you may lose some or all of your money. This is the main risk of owning corporate bonds, and it is why riskier companies have to offer higher interest rates to attract investors.

Default is rare for investment-grade bonds from stable companies, but it does happen. When a company files for bankruptcy, bondholders are paid before stockholders — you have a claim on the company's assets ahead of the people who own shares. But that does not mean you will recover your full investment. You might receive 50 cents on the dollar, or 10 cents, or nothing, depending on how much the company owes and what assets it has left.

This is why diversification matters. Owning bonds from many different companies reduces the damage if one of them defaults. Owning 20 bonds from 20 different companies is much safer than owning 20 bonds from the same company.

How to buy and hold corporate bonds

You can buy corporate bonds through a brokerage account — the same type of account you would use to buy stocks. You log in, search for the bond by its ticker or CUSIP number (a unique identifier), and place an order. The bond is held in your account, and interest payments are deposited into your cash balance automatically.

Some bonds trade on exchanges like stocks do, which means you can see live prices and buy or sell during market hours. Other bonds trade over-the-counter, meaning you work through a broker to find a seller or buyer. Over-the-counter bonds can be harder to sell quickly and may have wider price spreads.

You can also own corporate bonds indirectly through a bond fund or exchange-traded fund (ETF). These funds hold dozens or hundreds of bonds and pay you a share of the interest they collect. A fund handles the buying, selling, and reinvestment for you, which is simpler if you do not want to pick individual bonds yourself.

Corporate bonds versus other types of bonds

Corporate bonds compete with government bonds and municipal bonds for your money. Government bonds (Treasury bonds, notes, and bills) are issued by the U.S. federal government and are considered the safest bonds available because they are backed by the government's ability to tax and print money. They pay lower interest rates — often 3% to 5% — because the default risk is almost zero.

Municipal bonds are issued by states, cities, and local agencies to fund projects like roads and schools. They often pay interest that is free from federal income tax, which can make them attractive to high-income earners even if the stated interest rate is lower than a corporate bond.

Corporate bonds sit in the middle. They pay more than government bonds because companies are riskier than the government, but they do not have the tax advantages of municipal bonds. They are useful when you want higher income than Treasuries offer but do not want to take on the risk of individual stocks.

Frequently Asked Questions

Can I lose money on a corporate bond if I hold it to maturity?

Yes, if the company defaults before the maturity date. You will lose whatever principal the company cannot repay. However, if the company remains solvent and pays on time, you will receive your full $1,000 principal back on the maturity date, regardless of what happens to interest rates or the bond's market price.

What is the difference between a bond's coupon rate and its yield?

The coupon rate is the interest rate printed on the bond when it is issued — for example, 5% on a $1,000 bond means $50 per year. The yield is the actual return you get based on what you paid for the bond. If you buy that same bond for $900 on the secondary market, your yield is higher than 5% because you paid less. Yield accounts for the price you actually paid.

What happens to my bond if the company is acquired or merges with another company?

Usually, nothing changes when ready. The bond remains outstanding and the new combined company continues to pay you interest and principal as promised. However, the credit quality might improve or worsen depending on the financial strength of the acquiring company. You can check the new company's credit rating to see if the risk has changed.

Do I have to pay taxes on bond interest?

Yes. Interest from corporate bonds is taxed as ordinary income at your regular tax rate. Unlike municipal bond interest, which is often tax-free, corporate bond interest is fully taxable. You will receive a 1099-INT form at the end of the year reporting the interest you earned, and you must report it on your tax return.

Can I sell a bond before it matures?

Yes, you can sell a bond on the secondary market through your brokerage at any time. The price you receive depends on current interest rates and the company's credit quality. If rates have risen since you bought the bond, you will likely sell it for less than $1,000. If rates have fallen, you may sell it for more.
