You can buy corporate bonds through a brokerage account, directly from some companies, or through bond funds — each route has different costs and minimum investments

Corporate bonds are debt securities issued by companies, and you buy them the same way you buy stocks: through a brokerage firm. You open an account, fund it, search for the bond you want, and place an order. The bond issuer pays you interest (called the coupon) on a set schedule, and returns your principal when the bond matures. The main routes are a standard brokerage account, a bond-specific platform, or a bond mutual fund or exchange-traded fund (ETF) if you want to avoid picking individual bonds.

The practical difference between routes comes down to minimum investment, fees, and how much research you want to do. A brokerage account typically requires you to buy bonds in $1,000 increments and may charge a commission per trade. Bond funds let you invest smaller amounts and spread risk across many bonds, but you pay an annual management fee. Direct purchase from a company (sometimes available for Treasury bonds or corporate bonds) cuts out the middleman but is rare for corporate bonds and usually requires a larger upfront investment.

Key Takeaways

  • Corporate bonds are bought through brokerages like Fidelity, Charles Schwab, or Vanguard, and most require a minimum of $1,000 per bond plus a transaction fee.
  • You can search for bonds by issuer name, credit rating, maturity date, and yield, then place an order just as you would for a stock.
  • Bond funds and ETFs let you own pieces of many bonds with a smaller initial investment, but charge an annual fee ranging from 0.05% to 1% or more depending on the fund.
  • Before buying, check the bond's credit rating (from agencies like Moody's or S&P), maturity date, and whether it can be called early by the issuer.
  • Corporate bonds carry more risk than Treasury bonds because companies can default, so diversifying across multiple bonds or using a fund reduces that risk.

Opening a brokerage account and finding bonds to buy

Start by opening a brokerage account at a firm that offers bond trading. Major brokerages include Fidelity, Charles Schwab, E*TRADE, Vanguard, and TD Ameritrade. The account setup is straightforward: you provide personal information, verify your identity, and link a bank account to fund the account. Most brokerages do not charge account fees, though some have minimum deposit requirements (often $0 to $2,500 depending on the firm).

Once your account is funded, use the brokerage's bond search tool to find corporate bonds. You can filter by company name, credit rating, maturity date, yield, and other criteria. The search results show the bond's coupon rate (the interest rate), maturity date, current price, and yield to maturity (the total return you would receive if you held the bond until it matures). Compare several bonds before deciding; a higher yield usually means higher risk, so weigh that against your comfort level.

When you find a bond you want, place an order just as you would for a stock. You specify how many bonds you want to buy (typically in $1,000 increments), and the brokerage executes the trade. You will pay the bond's price plus a transaction fee, which ranges from $1 to $10 per bond depending on the brokerage. Some brokerages offer commission-free bond trading on certain bonds, so check whether that applies to your choice.

Understanding bond pricing and what you actually pay

Corporate bonds are priced as a percentage of their face value (par value), which is usually $1,000. A bond quoted at 102 costs $1,020 (102% of $1,000); a bond quoted at 98 costs $980. The price fluctuates based on interest rates, the company's credit quality, and time to maturity. If interest rates rise after you buy, the bond's price falls (because new bonds offer higher yields). If rates fall, the price rises.

When you buy a bond between coupon payment dates, you also pay accrued interest — the interest that has accumulated since the last payment. This is added to the bond's price. For example, if a bond pays interest twice a year and you buy it three months after the last payment, you pay the seller three months of accrued interest. You recover this when you receive the next coupon payment, so it is not an extra cost, just a timing adjustment.

The yield to maturity (YTM) is the total annual return you would receive if you held the bond until it matures, accounting for the price you paid, the coupon rate, and the time remaining. A bond with a 5% coupon might have a 4.8% yield to maturity if you buy it at a premium (above par), or a 5.2% yield if you buy it at a discount (below par). Compare yields across bonds to see which offers the better return for the risk.

Evaluating credit risk and bond ratings

Before buying, check the bond issuer's credit rating. Three major rating agencies — Moody's, Standard & Poor's (S&P), and Fitch — assign ratings that reflect the company's ability to pay interest and principal on time. Ratings range from AAA (highest quality, lowest risk) down to C or D (highest risk of default). Investment-grade bonds are rated BBB or higher; anything below BBB is considered high-yield or "junk" and carries significantly more risk.

Your brokerage's bond search tool usually displays the rating alongside the bond details. A higher-rated bond (AAA or AA) typically offers a lower yield because investors perceive less risk. A lower-rated bond (BB or B) offers a higher yield to compensate for the higher risk of default. There is no right choice — it depends on your risk tolerance and investment goals. If you are new to bond investing, starting with investment-grade bonds (BBB or higher) is generally safer.

Also check whether the bond is callable, meaning the issuer can redeem it early if interest rates fall. A callable bond limits your upside if rates drop, because the company will likely call it and you will have to reinvest at lower rates. The bond listing should note the call date and call price. Callable bonds typically offer a higher coupon to compensate for this risk.

Buying through bond funds or ETFs instead of individual bonds

If you want to avoid picking individual bonds or do not have enough capital to diversify across multiple bonds, a bond fund or ETF is a simpler route. A bond mutual fund pools money from many investors and buys a portfolio of bonds managed by a professional. An ETF is similar but trades like a stock on an exchange. Both let you own pieces of dozens or hundreds of bonds with a small initial investment — often $100 or less.

The trade-off is cost. Bond funds and ETFs charge an annual expense ratio (a percentage of your investment) that covers management and operating costs. This ranges from 0.05% per year for a low-cost Treasury ETF to 1% or more for actively managed corporate bond funds. Over time, these fees add up. A fund charging 0.5% per year costs $50 on a $10,000 investment; a fund charging 1% costs $100. Compare expense ratios across similar funds before choosing.

Bond funds also carry interest-rate risk: if rates rise, the fund's value falls (because existing bonds become less attractive). However, funds are professionally managed and automatically rebalanced, so you do not have to monitor individual bonds or decide when to sell. For most individual investors, especially those with less than $50,000 to invest in bonds, a low-cost bond ETF is often the simplest and most cost-effective choice.

Holding bonds to maturity versus selling before maturity

You have two basic strategies: hold the bond until it matures and collect all coupon payments, or sell it before maturity if you need the money or want to lock in a gain. If you hold to maturity, you know exactly what you will receive (assuming the company does not default), and you do not have to worry about price fluctuations. This is the "buy and hold" approach and works well if you are using bonds as a stable income source.

If you sell before maturity, you receive the current market price, which may be higher or lower than what you paid. If interest rates have fallen since you bought, the bond's price will have risen and you can sell at a gain. If rates have risen, the price will have fallen and you will take a loss. When you sell, you also pay a transaction fee (typically $1 to $10). Selling before maturity makes sense if you need liquidity or if you believe rates will rise and prices will fall further.

Keep in mind that selling a bond triggers a taxable event. If you sold at a gain, you owe capital gains tax. If you sold at a loss, you can deduct the loss against other gains (or up to $3,000 against ordinary income in a given year). Hold bonds in a tax-advantaged account like an IRA if possible to avoid this tax drag.

Tax treatment and account types for bond investing

Corporate bond interest is taxed as ordinary income at your federal tax rate, plus state and local taxes if applicable. This is less favorable than the preferential tax treatment of stock dividends or long-term capital gains. If you are in a high tax bracket, the after-tax yield on a corporate bond may be lower than it appears. For example, a 5% yield on a corporate bond might be worth only 3.25% after taxes if you are in the 35% federal tax bracket.

To minimize taxes, hold bonds in a tax-advantaged account such as a traditional IRA, Roth IRA, or 401(k). Inside these accounts, you do not pay tax on interest or capital gains until you withdraw the money (or ever, in the case of a Roth). If you must hold bonds in a taxable account, consider municipal bonds instead, which are exempt from federal tax (and sometimes state tax), though they typically offer lower yields.

If you sell a bond at a loss, you can deduct the loss against capital gains from other investments, or up to $3,000 against ordinary income in a single year. Any excess loss carries forward to future years. Keep records of your purchase price and sale price for tax reporting purposes.

Common mistakes to avoid when buying corporate bonds

One frequent mistake is chasing yield without considering risk. A corporate bond offering 8% when similar bonds offer 5% is usually offering that extra yield because the company is riskier. Before buying, understand why the yield is high and whether you are comfortable with the risk of default. Check the company's financial statements and credit rating, not just the coupon rate.

Another mistake is buying a single bond and assuming you are diversified. One company can default, leaving you with a total loss. If you are buying individual bonds, aim to own at least five to ten different bonds from different issuers and industries. If you cannot afford that, a bond fund or ETF is a better choice because it automatically diversifies.

A third mistake is ignoring the call feature. A callable bond can be redeemed early by the issuer, cutting short your investment and forcing you to reinvest at lower rates. Always check whether a bond is callable and understand the call date and call price before buying. Callable bonds should offer a higher yield to compensate for this risk, but many investors overlook it.

Frequently Asked Questions

What is the minimum amount I need to start buying corporate bonds?

Most brokerages require a minimum of $1,000 per bond, plus a transaction fee of $1 to $10. So your first purchase might cost $1,010 to $1,100. If you have less capital or want to diversify, a bond fund or ETF typically has a lower minimum, often $100 or less.

Can I lose money on a corporate bond?

Yes, in two ways. If you sell before maturity and interest rates have risen, the bond's price will have fallen and you will take a loss. If the company defaults, you may lose some or all of your principal. Holding to maturity eliminates price risk but not default risk. Diversifying across multiple bonds or using a bond fund reduces default risk.

How often do I get paid interest on a corporate bond?

Most corporate bonds pay interest semi-annually (twice per year), though some pay quarterly or annually. The coupon rate and payment dates are set when the bond is issued and do not change. Your brokerage will deposit the payment directly into your account on the payment date.

Should I buy individual bonds or a bond fund?

Individual bonds work well if you have at least $50,000 to invest and want to hold to maturity and collect predictable income. Bond funds work better if you have less capital, want professional management, or prefer not to research individual bonds. Funds charge annual fees but offer instant diversification and liquidity.

What happens if a company defaults on its bond?

If a company defaults, it stops paying interest and may not return your principal. Bondholders are paid before stockholders in bankruptcy, but you may recover only a fraction of what you are owed. This is why credit ratings and diversification matter — they reduce the impact of any single default on your portfolio.
