A corporate bond is a loan you make to a company. In exchange, the company agrees to pay you interest on a set schedule and return your principal on a fixed date. Understanding how corporate bonds work comes down to a handful of contract terms, a few risks that sit behind the interest rate, and the mechanics of buying, holding, and being taxed on the income. Most corporate bonds are sold in $1,000 increments, pay interest twice a year, and offer a higher yield than government debt of similar length because you’re taking on the credit risk of the issuer.1U.S. Securities and Exchange Commission. Investor Bulletin: What Are Corporate Bonds?
The Core Terms That Define a Bond
Four things shape the economics of any corporate bond, and they’re all fixed at issuance.
The par value, also called face value, is what the company promises to repay at maturity. For nearly all corporate issues that number is $1,000, and it anchors both the interest calculation and the price quote. A bond quoted at “98” is trading at 98% of par, or $980.1U.S. Securities and Exchange Commission. Investor Bulletin: What Are Corporate Bonds?
The coupon rate is the annual interest percentage the issuer pays you. A 5% coupon on a $1,000 bond produces $50 a year, almost always split into two $25 semiannual payments. These aren’t discretionary dividends. Missing one puts the company in default.1U.S. Securities and Exchange Commission. Investor Bulletin: What Are Corporate Bonds?
The maturity date is when the company must return your principal in full. The SEC groups maturities as short-term (under three years), medium-term (four to ten), or long-term (over ten), with some corporate issues running 30 years or more.1U.S. Securities and Exchange Commission. Investor Bulletin: What Are Corporate Bonds? Longer bonds usually pay higher coupons because you’re locked in longer and more exposed to changes in rates and in the company’s financial health.
All of this is written into a trust indenture, a contract between the company and a trustee (usually a bank) that represents bondholders. The indenture sets out the payment terms, redemption rules, and any collateral securing the debt. It’s the rulebook that holds the company to what it promised when it sold you the bond.2National Association of Bond Lawyers. Indenture or Trust Indenture/Agreement
Some Bonds Can End Early
Many corporate bonds carry embedded options that let one side exit before maturity. A callable bond lets the company repay your principal early, typically at par plus accrued interest and sometimes a small premium. Companies usually call bonds when interest rates drop, because they can refinance at a lower rate. That’s fine for the issuer and bad for you, because your money comes back exactly when reinvesting at a comparable yield is hardest. Callable bonds tend to offer higher coupons to compensate.3Investor.gov. Callable or Redeemable Bonds
A puttable bond works the other way. You have the right to force the company to buy the bond back at par before maturity, which is useful if rates rise and the bond’s market price drops. Puttable bonds are less common, and the protection shows up as a slightly lower coupon.
Credit Quality and Seniority Drive What You Earn
Two things about the issuer and the bond determine both your yield and what happens if the company fails.
Credit ratings from agencies such as Standard & Poor’s, Moody’s, and Fitch grade the issuer’s ability to pay. Investment-grade bonds sit in the upper tiers (AAA down to BBB- on the S&P scale, Aaa to Baa3 on Moody’s). Anything below that line is speculative-grade, commonly called high-yield or junk, and pays a higher coupon in exchange for a higher default risk. A downgrade alone, without any missed payment, can push a bond’s market price down.
Seniority is where your bond sits in the company’s debt hierarchy if it goes bankrupt. Historical recovery data from 1987 through 2025 shows senior secured bonds recover around 58 cents on the dollar on average, senior unsecured around 45 cents, senior subordinated around 30 cents, and other subordinated debt around 23 cents.4S&P Global Ratings. U.S. Recovery Study: Supportive Markets Boost Loan Recoveries Subordinated debt is often wiped out entirely, because senior creditors are paid first and little is left. If you’re buying lower-priority debt, the coupon should reflect that the downside case is severe.
Most corporate bonds are fixed-rate, but floating-rate notes exist too. Their coupons reset periodically against a benchmark, commonly the Secured Overnight Financing Rate (SOFR), plus a fixed spread. Floaters protect you when rates rise but shrink your income when rates fall.5iShares. Mechanics of Floating Rate Notes
The Risks Behind the Coupon
Corporate bonds are usually described as the steadier side of a portfolio, and compared to stocks they generally are. But they carry real risks that can hurt returns, especially if you can’t hold to maturity.
Interest rate risk. Bond prices move opposite to rates. When rates rise, your existing fixed-rate bond loses market value because new issues pay more. The longer the maturity, the larger the swing. A 30-year bond will drop far more from a 1% rate rise than a 3-year bond will.6U.S. Securities and Exchange Commission. Interest Rate Risk — When Interest Rates Go Up, Prices of Fixed-Rate Bonds Fall If you hold to maturity, this doesn’t affect the cash you receive.
Credit and default risk. The company may miss a payment or fail to return principal. Ratings help but they’re backward-looking, and even a workout in bankruptcy will usually pay less than par.
Reinvestment risk. When a bond matures or gets called, you have to redeploy the principal. If rates have fallen, the replacement earns less. Building a ladder of bonds that mature at staggered intervals is one common way to spread this out.
Liquidity risk. Corporate bonds don’t trade on a centralized exchange the way stocks do. Most trade over the counter, many trade infrequently, and bid-ask spreads can be wide. If you need to sell quickly, you may take a price well below what you’d consider fair. Large investment-grade issues are the most liquid; smaller or lower-rated bonds are progressively harder to move.
How Bond Interest Is Taxed
Corporate bond interest doesn’t get the preferential treatment that municipal bond interest or long-term capital gains do. The IRS treats it as ordinary taxable interest, taxed at your ordinary income rate.7Internal Revenue Service. Topic No. 403, Interest Received For 2026, federal ordinary income rates run from 10% to 37% depending on income and filing status. What matters for comparing bonds to other investments is your after-tax yield, not the coupon.
If you sell a bond for more than you paid, the profit is a capital gain. Held longer than a year, it qualifies for long-term rates; held a year or less, it’s taxed as ordinary income. Losses can offset gains elsewhere in your portfolio.
Bonds issued below par can trigger original issue discount (OID), a less obvious tax wrinkle. The IRS requires you to include a portion of the discount in your gross income each year, even though you don’t receive that cash until the bond matures.8Office of the Law Revision Counsel. 26 U.S. Code 1272 – Current Inclusion in Income of Original Issue Discount Your broker reports this on a 1099-OID, and your cost basis rises by the amount included each year. It’s phantom income you owe tax on before you see the money. Bonds maturing in a year or less, U.S. savings bonds, and tax-exempt obligations are exempt from the OID rules.
Buying a Corporate Bond
You need a brokerage account with fixed-income access, which most major online brokerages provide. From there, two markets exist. In the primary market, you buy a newly issued bond at the offering price; institutions dominate this, though some brokerages release new issues to retail clients. In the secondary market, bonds that have already been issued trade between market participants at prices that move with rates, credit conditions, and demand for the specific issue. Most individual investors buy secondary.
Finding the Bond and Reading the Documents
Every bond has a unique nine-character CUSIP identifier, mixing letters and numbers, that you enter into the trading platform to locate it.9CUSIP Global Services. About CGS Identifiers The CUSIP also lets you pull up the bond’s prospectus through the SEC’s EDGAR database, which provides free public access to corporate filings.10Investor.gov. EDGAR
The prospectus is the definitive legal document for the bond. It describes how the company will use the money, the payment schedule, any call provisions, and the covenants that restrict the company from doing things that could damage bondholders, such as loading on more debt.11Investor.gov. Offering Document (or Official Statement or Prospectus) Read the covenants. That’s your real protection.
Which Yield Number to Trust
The coupon rate tells you what percentage of par the bond pays each year. It doesn’t tell you your actual return if you’re buying at a price other than par. Yield to maturity (YTM) is the annualized return you’d earn holding to maturity with all coupons reinvested at the same rate, and it’s the standard comparison number.
For callable bonds, yield to call (YTC) assumes the issuer calls at the earliest opportunity, and yield to worst (YTW) is the lowest yield you’d receive across all possible call scenarios short of default.12Vanguard. Bond Yields 101: A Guide for Smarter Investing For a callable bond, YTW is the honest number. Looking only at YTM overstates what you’re likely to earn.
Costs on the Trade
When a broker-dealer sells you a bond out of its own inventory (a principal transaction), the price includes a markup over what the firm paid. Under FINRA Rule 2232, broker-dealers must disclose that markup on retail customer confirmations for corporate debt when the firm executed an offsetting trade the same day. It appears as both a dollar figure and a percentage of the prevailing market price.13FINRA. 2232. Customer Confirmations Your confirmation also links to FINRA’s BondFacts page for that CUSIP, where you can check recent trade prices and gauge whether you paid a fair number.14FINRA. Fixed Income Confirmation Disclosure: Frequently Asked Questions
Some brokerages also charge a flat commission on secondary market trades. Vanguard, for example, charges $1 per $1,000 of face value with a $250 maximum, plus $25 if you place the order over the phone.15Vanguard. Brokerage Services Commission and Fee Schedules Between markup and commission, costs can eat into your yield more than you’d expect on smaller orders. Check the fee schedule before you trade.
Placing and Settling the Trade
Enter the CUSIP, review the bid, ask, yield, and available inventory, and specify how many bonds you want in $1,000 multiples. Most brokerages require a minimum of one bond.15Vanguard. Brokerage Services Commission and Fee Schedules Before you confirm, the platform shows the total cost including accrued interest, which is the portion of the next coupon that has built up since the last payment. You reimburse the seller for that amount at purchase and get it back when the next full coupon lands.
After you confirm, you get a digital trade confirmation with the execution price, time of trade, and any markups or commissions. Settlement is now one business day after the trade date.

Bond ETFs as an Alternative
If choosing individual bonds is more work than you want, corporate bond exchange-traded funds hold a diversified portfolio and trade on a stock exchange like a share. You get intra-day liquidity that individual bonds don’t offer, which is a real advantage over the dealer-driven secondary market.
The trade-offs matter. An individual bond gives you a known coupon and a known return-of-principal date. A bond ETF has no fixed maturity; the fund constantly buys and sells bonds, so your principal value fluctuates with the market indefinitely. You also pay a management fee. As of mid-2025, the median expense ratio for bond ETFs is 0.29%.17State Street Global Advisors. Individual Bonds vs. Bond Funds: A Comparison On a low-yielding investment-grade portfolio, that’s a noticeable drag. ETFs typically distribute income monthly rather than semiannually, which some investors prefer for cash flow.
Target-maturity bond ETFs sit in between. They hold bonds that all mature the same year and wind down at that point, returning your share of the principal. If you want diversification without building a ladder of individual bonds yourself, they’re a reasonable middle path.
