Dax Function: ODDFYIELD

Q: What happens if I omit the basis parameter?

The function defaults to a 30/360 day count basis if no basis parameter is provided.

Q: What’s the difference between ODDFYIELD and YIELD?

ODDFYIELD adjusts for irregular first periods, while YIELD handles standard payment intervals.

Category: Financial Functions

The ODDFYIELD function in Power BI is a financial function that calculates the yield of a bond with an odd (irregular) first period. It evaluates the annualized yield rate based on the bond’s settlement date, maturity date, coupon rate, price, and other characteristics.

Purpose

Computes the annual yield for bonds with an irregular first interest period.
Adjusts for non-standard cash flow patterns in the first period of a bond’s life.

Type of Calculations

Performs financial yield calculations, accounting for irregular first-period cash flows.
Involves compounding interest calculations and day-count conventions.

Practical Use Cases

Bond Analysis: Calculate the annualized yield for bonds issued with an odd first period.
Portfolio Management: Ensure accurate yield representation in portfolios with irregular-period bonds.
Scenario Modeling: Analyze how changes in bond price, coupon rate, or other parameters affect yield.


ODDFYIELD(settlement, maturity, issue, first_coupon, rate, price, redemption, frequency, [basis])

Parameter	Type	Description
`settlement`	Scalar	The bond’s settlement date. The date after issuance when the bond is traded to the buyer. Must be a valid date.
`maturity`	Scalar	The bond’s maturity date. The date when the principal is due. Must be a valid date.
`issue`	Scalar	The bond’s issue date. The date when the bond was first issued. Must be a valid date.
`first_coupon`	Scalar	The first coupon date. The date when the first interest payment is made. Must be a valid date.
`rate`	Scalar	The bond’s annual coupon rate. Expressed as a decimal (e.g., 5% = 0.05).
`price`	Scalar	The bond’s price per $100 face value.
`redemption`	Scalar	The bond’s redemption value per $100 face value. For example, 100 = par, 105 = premium.
`frequency`	Scalar	The number of coupon payments per year: 1 = annual, 2 = semi-annual, 4 = quarterly.
`[basis]`	Scalar	(Optional) The day count basis: 0 = 30/360 (default), 1 = actual/actual, 2 = actual/360, 3 = actual/365, 4 = 30E/360.

How Does ODDFYIELD Dax Function Works

Mathematical Principle

Yield Definition: The yield is calculated by solving the bond pricing equation for yield, considering:
- Coupon payments.
- Redemption value.
- Bond price.
- Irregular first-period adjustments.
Adjustment for Odd Period:
- The first period’s length may differ from regular intervals.
- Yield calculation incorporates this irregularity in its compounding formula.

What Does It Return?

Scalar Value: Returns the annualized yield rate as a numeric value.
The value is expressed as a decimal (e.g., a yield of 5% is returned as 0.05).

When Should We Use It?

Irregular First-Period Bonds: For bonds with an odd first payment schedule.
Investment Decisions: To compare yields of bonds with irregular versus regular payment periods.
Portfolio Diversification: Evaluate the performance of bonds with non-standard cash flows.

Examples

Basic Usage :

Calculate the yield of a bond with the following parameters:

Settlement Date: 2025-01-01
Maturity Date: 2030-01-01
Issue Date: 2024-06-01
First Coupon Date: 2024-12-01
Coupon Rate: 5% (0.05)
Price: 101.50
Redemption Value: 100
Frequency: 2 (Semi-annual)


ODDFYIELD(DATE(2025, 1, 1), DATE(2030, 1, 1), DATE(2024, 6, 1), DATE(2024, 12, 1), 0.05, 101.50, 100, 2)

Result: 0.0475 (approximately 4.75%).

Column Usage

Evaluate yields for multiple bonds with varying parameters:

BondID	Settlement	Maturity	Issue	FirstCoupon	Rate	Price	Redemption	Frequency
1	2025-01-01	2030-01-01	2024-06-01	2024-12-01	0.05	101.50	100	2
2	2025-02-01	2035-02-01	2024-09-01	2025-03-01	0.07	99.00	100	1

Add a calculated column:


Yield = ODDFYIELD(Bonds[Settlement], Bonds[Maturity], Bonds[Issue], Bonds[FirstCoupon], Bonds[Rate], Bonds[Price], Bonds[Redemption], Bonds[Frequency])

Advanced Usage

Combine ODDFYIELD with other DAX functions for comparative analysis:


YieldDifference =
ODDFYIELD(Bonds[Settlement], Bonds[Maturity], Bonds[Issue], Bonds[FirstCoupon], Bonds[Rate], Bonds[Price1], Bonds[Redemption], Bonds[Frequency]) -
ODDFYIELD(Bonds[Settlement], Bonds[Maturity], Bonds[Issue], Bonds[FirstCoupon], Bonds[Rate], Bonds[Price2], Bonds[Redemption], Bonds[Frequency])

Measures yield difference between two pricing scenarios.

Tips and Tricks

Ensure dates are formatted correctly to avoid errors.
Use consistent day-count conventions (basis) across calculations.
Rate and Price Units: Ensure correct units (decimal for rate, per $100 for price).
Invalid Dates: Avoid errors caused by mismatched or invalid date ranges.

Performance Impact of ODDFYIELD DAX Function:

Efficient for small to moderate datasets.
Optimize for large datasets by caching results for repeated calculations.
