 # YIELDMAT

In this comprehensive guide, we will explore the YIELDMAT function in Microsoft Excel. The YIELDMAT function is a financial formula used to calculate the yield to maturity of a security that pays interest at maturity. This function is particularly useful for investors and financial analysts who need to determine the yield of a bond or other fixed-income security. We will cover the syntax of the YIELDMAT function, provide examples, share tips and tricks, discuss common mistakes, troubleshoot issues, and introduce related formulae.

## YIELDMAT Syntax

The YIELDMAT function in Excel has the following syntax:

YIELDMAT(settlement, maturity, issue, rate, pr, [basis])

Where:

• settlement – The settlement date of the security, which is the date after the issue date when the security is traded to the buyer.
• maturity – The maturity date of the security, which is the date when the security expires.
• issue – The issue date of the security, which is the date when the security was issued.
• rate – The annual interest rate of the security.
• pr – The security’s price per \$100 face value.
• [basis] – (Optional) The day count basis to be used. If omitted, the default value is 0, which represents the US (NASD) 30/360 day count basis. Other available options are: 1 for Actual/Actual, 2 for Actual/360, 3 for Actual/365, and 4 for European 30/360.

## YIELDMAT Examples

Let’s look at some examples of how to use the YIELDMAT function in Excel:

Example 1: Calculate the yield to maturity of a security with a settlement date of January 1, 2022, a maturity date of December 31, 2022, an issue date of January 1, 2021, an annual interest rate of 5%, and a price of \$98 per \$100 face value.

=YIELDMAT(“2022-01-01”, “2022-12-31”, “2021-01-01”, 0.05, 98)

This formula will return the yield to maturity for the given security, taking into account the default day count basis (US 30/360).

Example 2: Calculate the yield to maturity of a security with the same parameters as in Example 1, but using the Actual/Actual day count basis.

=YIELDMAT(“2022-01-01”, “2022-12-31”, “2021-01-01”, 0.05, 98, 1)

This formula will return the yield to maturity for the given security, using the Actual/Actual day count basis.

## YIELDMAT Tips & Tricks

• Ensure that the settlement, maturity, and issue dates are entered in a recognized date format in Excel. You can use the DATE function to create a date value if necessary.
• Remember that the rate and pr arguments should be entered as decimal values. For example, a 5% interest rate should be entered as 0.05.
• When comparing the yields of different securities, make sure to use the same day count basis for all calculations to ensure accurate comparisons.
• Use the optional [basis] argument to adjust the day count basis as needed for your specific analysis.

## Common Mistakes When Using YIELDMAT

• Entering the rate and pr arguments as percentages instead of decimal values. To convert a percentage to a decimal, divide the percentage by 100.
• Using an incorrect or unrecognized date format for the settlement, maturity, and issue dates. Ensure that the dates are entered in a format that Excel can recognize.
• Forgetting to include the optional [basis] argument when a different day count basis is required for the analysis.
• Confusing the order of the arguments in the YIELDMAT function, which can lead to incorrect results. Always double-check the order of the arguments to ensure accuracy.

## Why Isn’t My YIELDMAT Working?

If your YIELDMAT function is not working as expected, consider the following troubleshooting steps:

• Check the format of the settlement, maturity, and issue dates to ensure they are recognized by Excel.
• Verify that the rate and pr arguments are entered as decimal values, not percentages.
• Ensure that the correct day count basis is being used by including the optional [basis] argument if necessary.
• Double-check the order of the arguments in the YIELDMAT function to ensure they are entered correctly.
• Look for any error messages or error codes returned by Excel, which can provide additional information about the issue.

## YIELDMAT: Related Formulae

Here are some related financial formulae in Excel that you may find useful when working with the YIELDMAT function:

• YIELD – Calculates the yield of a security that pays periodic interest.
• YIELDDISC – Calculates the annual yield for a discounted security, such as a Treasury bill.
• PRICE – Calculates the price per \$100 face value of a security that pays periodic interest.
• PRICEMAT – Calculates the price per \$100 face value of a security that pays interest at maturity.
• ACCRINT – Calculates the accrued interest for a security that pays periodic interest.

By mastering the YIELDMAT function and related formulae, you can enhance your financial analysis skills and make more informed investment decisions.
