Introduction

Investing in treasury bills (T-bills) is a popular way for individuals and businesses to earn a low-risk return on their investments. T-bills are short-term government securities with maturities ranging from a few weeks to a year. In this article, we will explore how to calculate the yield on treasury bills, using the example of XYZ Corporation investing $\$14,000$ into 91-day T-bills with an interest rate of $2.2\%$ . We will also consider the impact of a $\$25$ commission charged by the broker.

Understanding Yield

Yield is the rate of return on an investment, taking into account the interest earned and any fees or commissions charged. It is a key metric for investors, as it helps them compare the performance of different investments. In the case of T-bills, the yield is typically expressed as an annual percentage rate (APR).

Calculating the Yield on T-Bills

To calculate the yield on T-bills, we need to follow these steps:

Determine the interest earned: The interest earned on the investment is calculated by multiplying the principal amount by the interest rate. In this case, the principal amount is $\$14,000$ and the interest rate is $2.2\%$ .
Add the commission: The broker charges a $\$25$ commission, which needs to be added to the interest earned.
Calculate the total return: The total return is the sum of the interest earned and the commission.
Calculate the yield: The yield is calculated by dividing the total return by the principal amount and multiplying by 100 to express it as a percentage.

Example Calculation

Let's calculate the yield on the T-bills using the example provided:

Interest earned: $\$14,000 \times 2.2\% = \$308$
Add the commission: $\$308 + \$25 = \$333$
Calculate the total return: $\$333$
Calculate the yield: $\frac{\$333}{\$14,000} \times 100\% = 2.37\%$

Factors Affecting Yield

Several factors can affect the yield on T-bills, including:

Interest rate: The interest rate on T-bills can fluctuate over time, affecting the yield.
Commission: The commission charged by the broker can reduce the yield.
Maturity: The maturity of the T-bill can affect the yield, with longer maturities typically offering higher yields.
Inflation: Inflation can erode the purchasing power of the investment, reducing the yield.

Conclusion

Calculating the yield on treasury bills is a straightforward process that involves determining the interest earned, adding the commission, calculating the total return, and calculating the yield. By considering the factors that affect yield, investors can make informed decisions about their investments. In the example provided, the yield on the T-bills is $2.37\%$ , which is lower than the interest rate of $2.2\%$ due to the commission charged by the broker.

Recommendations

Based on the example provided, we recommend the following:

Investors should carefully consider the commission charged by the broker: The commission can significantly reduce the yield on the investment.
Investors should consider the maturity of the T-bill: Longer maturities may offer higher yields, but they also come with greater risk.
Investors should monitor interest rates: Changes in interest rates can affect the yield on T-bills.
