How Much Interest Does $500,000 Earn Per Year?

The savings and fixed-income investment landscape is constantly evolving, offering a wide range of options to grow your wealth. Whether you’re considering high-yield savings accounts, certificates of deposit, bonds or other fixed-income investments, it’s important to have a good idea of the potential returns so you can make informed financial decisions. Before committing to any investment, evaluate how much your money can earn over time, factoring in interest rates, risk levels and market conditions. Here’s a breakdown of how much interest $500,000 can generate per year.

To ensure your investments align with your financial goals and risk tolerance, consider consulting with a financial advisor for a customized strategy and guidance.

Interest on Fixed-Income Investments

Interest provides the incentive to invest rather than simply holding onto cash. For many, the goal of generating passive income through interest is a key part of their financial strategy. When people discuss living off interest, they’re typically referring to returns from fixed-income investments. We’ll review the interest rates you can expect from four common fixed-income instruments. As well as if you can get high interest on $500k (though that depends on what you consider “high”).

1. Bonds

Bonds are a popular fixed-income investment, as they’re associated with a lower risk of negative outcomes compared to stocks. With bonds, the return on your investment is often known at the point of purchase. Although it’s often a lower return than the best-case scenario of riskier investments, it provides value when balancing a portfolio.

When you purchase a standard bond, you agree to receive a set percentage of the price of your bond in interest. This percentage is called the coupon rate. Its size is largely dependent on the interest rates in the market at the time you purchase the bond.

Say you bought $500,000 in bonds that have a 3.45% coupon rate. You would then receive 3.45% of your balance in interest throughout the term of your bond.

Most bonds compound semi-annually. So if you put a bond with a term longer than six months, you will also have the opportunity to earn interest on your interest.

2. Treasury Bonds

Many investors are drawn to U.S. Treasury bonds (T-bonds) because they are considered the safest investment. The U.S. government guarantees their return, virtually eliminating the risk of loss.

Buying newly issued T-bonds can be complex. The purchase price isn’t fixed beforehand because bonds are sold through government auctions. This means you may pay slightly more or less than expected. Treasury bonds pay interest every six months throughout their term.

For example, say you buy a 30-year bond with a $500,000 face value and a 3.5% coupon rate. You’ll receive $17,500 in annual interest, split into two payments. Interest is based on the bond’s face value, but buying below face value increases your effective return.

Shorter-term bonds follow the same interest calculation and payment schedule. However, their interest rates are usually lower. As of June 2025, two-year Treasury bond rate is 3.74%. On $500,000, this would generate about $18,700 annually.

3. Corporate Bonds

Many corporations choose to issue bonds as a fundraising strategy. Since even the sturdiest companies can’t quite match the guarantee of Treasury bonds, they’ll often issue those bonds with higher interest rates. This makes them an attractive proposition for investors who don’t mind marginally more risk.

Similar to Treasuries, most corporate bonds have a fixed interest rate attached to the par value of the bond. That interest rate determines the annual amount of interest to be paid out most frequently in semi-annual installments.

According to the Federal Reserve Bank of St. Louis, high-grade corporate bonds currently have an average yield of 6.42%. For the sake of our example, let’s say you purchased these corporate bonds with a par value of $500,000.

Would you get high interest on $500k? That depends. However, you would be looking at annual interest payments of $32,100.

4. Certificates of Deposit (CDs)

A certificate of deposit (CD) is similar to a bond. You agree to lend money to a bank in exchange for interest. CDs come in various term lengths, often offering more options than bonds. Terms range from as short as seven days to 10 years or more.

One advantage CDs have over bonds is the variety of choices. Most large banks offer multiple CD options, making it easier to find one that fits your needs. Additionally, CD interest compounds monthly, which can increase earnings over time.

With equal term lengths and interest rates, CDs typically generate more interest than bonds due to monthly compounding. However, because of this advantage, CDs often have slightly lower interest rates than comparable bonds.

For example, investing $500,000 in a Capital One 60-month CD with a 3.50% interest rate and monthly compounding would yield $95,471 in total interest. That amounts to an annual return of $19,094.

5. Savings Accounts

If saying goodbye to your principal for a period of up to 30 years seems a bit worrisome to you, you can also earn interest on your money by placing it in a high-yield savings account. Keep in mind, having immediate access to your funds comes at the trade-off of much lower interest rates.

For this example, let’s say you placed $500,000 in a high-yield savings account with a 2.15% APY. After one year, you will have earned $10,750 in interest. This rate is likely insufficient to keep up with annual inflation. This means your money will become less valuable at a higher rate than when it’s accruing interest. You’ll also want to check the fine print of your savings account for things like maximum balance thresholds and tiered interest rates, if you’re considering this approach.

6. Money Market Accounts

Say you feel the need to have even greater access to your funds than a savings account can provide. After all, many savings accounts limit how many times you can make a withdrawal per year without paying a fee. In this case, a money market account could serve as an alternative.

Keep in mind, however, that while you may be able to withdraw from the account more freely, you pay the price of even lower interest rates. Most competitive money market accounts offer APYs between 1.6% and 1.8%. A 1.8% APY, compounding monthly, would earn $9,074.62 in the first year after depositing $500,000. As it’s unlikely that you’ll need that much money with that level of liquidity, this is likely not the wisest approach.

Can You Retire With $500,000?

Retiring with $500,000 is possible, but the outcome depends heavily on your cost of living, spending habits, and whether you have other sources of income. The 4% rule is a widely used benchmark—it suggests withdrawing 4% of your savings annually to avoid depleting your funds too early. Applied to $500,000, this gives you $20,000 per year from your portfolio.

Adding Social Security, which averages around $23,000 annually for many retirees, your total income could reach more than $40,000 a year. For individuals or couples living in low-cost areas with paid-off housing and no major medical issues, this income level could be workable. But for others, it may fall short, especially if inflation, health care, or long-term care costs rise sharply over time.

In real terms, $500,000 is a lean retirement unless it’s paired with other assets or income streams. A solid retirement strategy on that base may require downsizing, relocating, or delaying retirement to reduce withdrawals. Without adjustments, this balance may not support a long retirement horizon, especially in high-expense regions or for retirees with ongoing financial responsibilities.

How Should You Invest $500,000?

A $500,000 portfolio needs to be structured for both income and protection. That means balancing growth and safety. Allocating too much to stocks invites volatility, while putting it all into fixed-income instruments like CDs or bonds may not keep pace with inflation. Your investment strategy must produce sustainable income and preserve principal as long as possible.

One common model is a diversified portfolio split between equities and fixed income. For example, stocks or equity funds can drive long-term growth, while bonds, TIPS, and CDs deliver steady interest. For some, dividend-paying stocks or annuities may also serve as income tools. Asset location—where each investment type is held for tax efficiency—matters, especially in taxable accounts versus IRAs.

There is no fixed formula, but a well-built allocation should reflect your withdrawal timeline, tolerance for loss, and income needs. A poorly allocated $500,000 can erode quickly. A well-managed one, paired with moderate withdrawals and smart risk control, can last for decades.

Bottom Line

Striving to achieve high interest on $500k looks different depending on the individual. Factors like how much risk you’re assuming, the term length you choose, the broader economic environment at your time of purchase and the frequency at which your interest compounds will all play a role in calculating how much you earn on your principal investment.
