In a nutshell, by investing in a bond fund, you will have your money managed for you by an established fund provider. Providers such as Vanguard will actively buy and sell bonds in the open marketplace, with the view of making money for their investors.Bond funds come in a range of shapes, sizes, and risk spectrums. For example, while some focus on low-risk government securities like Treasury bonds and Gilts, others target higher-risk markets. This might include corporations based on the emerging economies or government bonds that are backed by weaker currencies. Either way, you need to choose a bond fund that meets your appetite for risk.Let’s look at a quick example of a bond index fund that might work in practice.You invest $10,000 into a bond index fundThe fund manager buys and sells US corporate bondsAt the end of each month, you will receive your share of coupon payments that the index fund receivesThe exact monthly yield that you receive will vary, depending on the economic activity of the fundAt the end of each year, you will receive your share of any capital gains that the bond fund madeCapital gains relate to profits made when the fund manager sold bonds on the open marketplace at a profitAs you can see from the above example, there’s much to learn about bond fund indexes, not least because you have the potential to make money on two fronts. Firstly, you will receive coupon payments at the end of each month. The amounts that you receive will be proportionate to the amount you invest at the bond fund. Secondly, you will also receive capital gains at the end of each year, which are based on the profits made when the fund manager sold bonds on the secondary market. Note: Understanding how much money you can make from a bond fund can be difficult at first glance, so we’ll explain this in more detail further down this guide.What is the Vanguard Total Bond Market Index Fund?So now that you have a basic understanding of how a bond fund works in practice, we are now going to explore the specifics of the Vanguard Total Bond Market Index Fund. In a nutshell, the Vanguard Total Bond Market Index Fund is one of the largest bond funds in the financial markets. At the time of writing, the fund has more than $259 billion under management, with an investment basket that contains over 17,000 individual bonds.The fund is perceived as a low-risk investment product, due to the types of bonds that it targets. While the exact numbers will vary depending on market conditions, the Vanguard Total Bond Market Index Fund typically invests 30% of its portfolio in corporate bonds, with the rest made up of government securities.30% in Corporate BondsThe Vanguard Total Bond Market Index Fund will invest around 30% of its portfolio into corporate bonds. These are usually large-scale companies that are listed on either the New York Stock Exchange (NYSE) or NASDAQ. Although the corporate bond space does come with more risk in comparison to government securities, Vanguard will focus on low-risk entities. Think along the lines of Nike, Apple, and Ford Motors.70% in US SecuritiesThe Vanguard Total Bond Market Index Fund will invest the remainder of its capital into low-risk government securities. For those unaware, these refer to US Treasury Bills. As such, the bonds are backed by the US government, meaning they are virtually risk-free. This allows you to enjoy the higher yields that come with corporate bonds, while at the same time having the safety net of US securities.How Does the Vanguard Total Bond Market Index Fund Work?As noted above, Vanguard currently has a surplus of 17,000 corporate and government bonds within its basket. This allows Vanguard to diversify across multiple segments of the bonds space, allowing it to mitigate the risks of default. Irrespective of the type of bond that Vanguard invests in, the fund provider will rarely hold on to its bonds until maturity.Instead, the fund is actively managed, meaning that it will constantly buy and sell its bonds on the secondary marketplace. As a result, you won’t know how much you are going to make when investing in the Vanguard Total Bond Market Index Fund. Instead, the yield is determined by the performance of the fund manager.We are now going to explain in more detail how you can make money from the Vanguard Total Bond Market Index Fund.Monthly Interest Payments at VanguardIf you’ve previously invested in bonds, then you’ll know that they typically come with coupon payments that are distributed every 6 or 12 months. This allows you to earn passive income without needing to actively manage your investment.This also allows you to know exactly how much your investment is going to make until the bonds mature. However, the Vanguard Total Bond Market Index Fund operates in a completely different manner, not least because it does not hold on to its bonds until maturity. Instead, it will attempt to profit when the value of the bond goes up.You will still receive coupon payments for as long as Vanguard keeps hold of them. When you consider that the Vanguard Total Bond Market Index Fund has more than 17,000 bonds in its basket, this means that the provider is likely to receive coupon payments throughout the month.When it does, you will receive your share of the coupon payment, proportionate to the amount you have invested at Vanguard.The amount that you receive each month will never be the same. This is because Vanguard will sell bonds, and then purchase new ones. Each bond will, of course, come with a different coupon rate, which is why your monthly interest payments will vary.Here’s an example of how you might make monthly interest payments via the Vanguard Total Bond Market Index Fund.You have $30,000 invested in the Vanguard Total Bond Market Index FundDuring month 1, Vanguard receives 0.5% in coupon payments from its total bond investmentsAs you have invested $30,000, this means that you will receive $150 in interest (0.5% x $30,000)In month 2, Vanguard receives 1% in coupon payments, so you make an additional $300 (1% x $30,000)Annual Capital Gains at VanguardHere’s where things get interesting. While a traditional bond investment only allows you to earn annual or bi-annual coupon payments until the bonds mature, a bond fund also gives you the chance to make capital gains. This is because Vanguard will actively look to sell its bond holdings on the secondary market at a higher price than it paid. Although corporate and government bonds always come with a fixed rate of interest, the underlying value of the bonds will go up or down based on market conditions.Let’s say that Vanguard holds bonds in Nike PLC, which pays an annual coupon rate of 5%.When the bonds were issued, Nike PLC had a Standard & Poor’s risk rating of BB.However, as Nike PLC published strong earnings in its most recent report, it has since been upgraded to a rating of A.This means that the risks of the bonds are now much lower, so the value of the bonds will go up.When bonds increase in value on the secondary market, bondholders can sell them at a premium.As such, funds like Vanguard will make a profit for their investors, which is paid as capital gains.It would be a logistical nightmare to distribute capital gains to investors as and when Vanguard sells its bonds, which is why they are paid at the end of each year. The amount that you receive will be determined by the amount you have invested at Vanguard. For example, if the fund provider reports an annual gain of 7%, and you have $5,000 invested, you will receive $350 in capital gains. This is on top of the monthly coupon payments that you received throughout the year. It is important to remember that the value of bonds can also go down. If Vanguard is holding such bonds, then it might be forced to sell them at a lower price than it paid. This means that the investment will result in a loss. Once again, this is why you will never know how much money you will make from a bond index fund investment.Fees and Minimum InvestmentAs is the case with all bond index funds, you will need to pay a fee at Vanguard. This is to cover the costs of having your money actively managed for you. Don’t forget, the fund comes with a team of highly experienced investors that will be analyzing the markets each and every day. This not only includes adding new bonds to its basket but also the process of looking for selling opportunities.The Vanguard Total Bond Market Index Fund charges an annual expense ratio of 0.15%, which is very competitive. The fee is calculated against the amount you have invested with the provider. For example, a $50,000 investment would cost you just $75 per year.If you’re wondering why the fees are so low, this is because providers like Vanguard need capital to fund their operations. If they didn’t have investors ploughing cash into the business, they wouldn’t be able to meet their investment goals.You also need to consider that Vanguard needs sufficient levels of cash flow at its disposal to meet withdrawals.In terms of minimum investments, the Vanguard Total Bond Market Index Fund permits deposits of $3,000 or more.If you don’t want to inject $3,000 in one-hit, then you might be able to use a third-party to access the fund. They usually allow you to invest less, as the account minimum is covered by other investors at the platform.Investment Returns on the Vanguard Total Bond Market Index FundAlthough historical returns should not be used to determine the future direction of bond funds, at the very least it allows us to gauge how much you might be able to make. The following figures are based on annualized returns.Year-to-Date: 2.62%1-Year: 10.37%3-Years: 4.63%%5-Years: 3.33%10-Years: 3.73%As you can see from the above figures, the Vanguard Total Bond Market Index Fund has provided its investors with steady returns over the past decade. The yields mirror that of the types of securities that Vanguard buys and sells, so investors have enjoyed decent gains on an investment that carries little risk.For example, let’s say that you invested $15,000 into the Vanguard Total Bond Market Index Fund 10 years ago, and you haven’t made any withdrawals. Based on a 10-year annualized yield of 3.73%, your $15,000 investment would now be worth $21,633.91. This represents an ROI (return on investment) of 44.22%, which is attractive.Withdrawing Your Investment at VanguardYou also need to make some considerations regarding withdrawals when investing in an index fund. This is because some providers will install an initial redemption period. This means that you cannot withdraw your investment until the redemption period concludes.For example, if the fund has a minimum redemption of 12 months, this means that your cash will be locked up for 1 year. After that, you can make a withdrawal. However, you then need to explore whether or not the fund provider changes a withdrawal fee, which is often the case.The Vanguard Total Bond Market Index Fund does not have a redemption date, so you can make a withdrawal whenever you see fitHowever, Vanguard will charge you $50 if you make a withdrawal within 60 days of making your investmentThe amount you get back will be based on the fund’s NAV (Net Asset Value).Once you redeem your investment, Vanguard will transfer the funds into your bank account within 3-5 days.Ultimately, the Vanguard Total Bond Market Index Fund is a reasonably liquid asset class, as you’ll be able to turn your investment into cash in less than one week.Vanguard Total Bond Market Index Fund: Pros and Cons Pros Vanguard is one of the most established fund providers in the investment space The fund invests in low-risk securities 30% of the fund is injected into corporate bonds, with the rest invested in government securities The fund has provided an annualized yield of 3.73% over the past 10 years You can withdraw your investment at any time Low expense ratio of 0.15% Cons Minimum investment of $3,000 if going direct with Vanguard Yields are much lower than the stocks and shares arena You will need to use a broker if Vanguard doesn’t support your country Unable to assess how much you will make as yields vary on a month-by-month basisHow do I Invest in the Vanguard Total Bond Market Index Fund?Like the sound of the Vanguard Total Bond Market Index Fund and looking to make an investment today?
