Master the ODDFPRICE Function: Calculate Bond Prices with Odd First Coupon Periods
=ODDFPRICE(settlement, maturity, issue, first_coupon, rate, yld, redemption, frequency, [basis])The ODDFPRICE function is a specialized financial formula in Excel designed to calculate the price of a security that has an odd (irregular) first coupon period. This function is essential for financial analysts, bond traders, and investment professionals who need to work with bonds issued between standard coupon dates. Unlike standard bond pricing formulas that assume regular coupon intervals, ODDFPRICE accounts for the irregular timing of the first coupon payment, making it indispensable for accurate fixed-income security valuations. When a bond is issued on a date that doesn't align with the regular coupon payment schedule, the first coupon period becomes irregular in length. This situation requires special calculation methods to determine the accurate present value of the security. The ODDFPRICE function handles this complexity automatically, incorporating the settlement date, maturity date, issue date, and first coupon date to produce precise pricing calculations. Understanding and implementing ODDFPRICE is crucial for professionals working in treasury departments, investment banking, or portfolio management where accurate bond valuation directly impacts financial decisions and investment returns.
Syntax & Parameters
The ODDFPRICE formula contains nine parameters, with eight required and one optional. The settlement parameter specifies the date when the bond is purchased or transferred. The maturity parameter indicates when the bond reaches its end date and principal is repaid. The issue parameter marks the original issuance date of the security. The first_coupon parameter is critical—it defines when the first coupon payment occurs, which is typically irregular compared to subsequent coupons. The rate parameter represents the annual coupon interest rate, expressed as a decimal (for example, 0.05 for 5%). The yld parameter is the annual yield to maturity, also expressed as a decimal. The redemption parameter specifies the redemption value at maturity, typically 100 for bonds quoted as a percentage of par value. The frequency parameter indicates how many times per year coupons are paid: 1 for annual, 2 for semi-annual, or 4 for quarterly payments. The optional basis parameter determines the day-count convention used in calculations. It accepts values 0 (US 30/360), 1 (Actual/Actual), 2 (Actual/360), 3 (Actual/365), or 4 (European 30/360). If omitted, Excel defaults to basis 0. Understanding these parameters thoroughly ensures accurate bond pricing and prevents calculation errors in financial modeling.

Corporate Bond with Odd First Coupon
=ODDFPRICE(DATE(2024,3,20),DATE(2030,12,15),DATE(2024,3,15),DATE(2024,6,15),0.045,0.048,100,2,1)This formula calculates the fair price of the corporate bond accounting for the irregular first coupon period from March 15 to June 15, 2024. The settlement date is March 20, 2024, and the formula uses semi-annual frequency (2) with Actual/Actual day-count basis (1) for precise calculation.
Government Treasury Bond Valuation
=ODDFPRICE(DATE(2024,2,5),DATE(2030,8,1),DATE(2024,2,1),DATE(2024,5,1),0.032,0.035,100,2,0)This example demonstrates Treasury bond pricing with an odd first coupon period. The US 30/360 basis (0) is standard for government securities. The formula accurately reflects the irregular first coupon from February 1 to May 1, 2024.
Municipal Bond with Quarterly Coupons
=ODDFPRICE(DATE(2024,1,15),DATE(2028,12,15),DATE(2024,1,10),DATE(2024,4,15),0.028,0.031,100,4,2)Municipal bonds often have quarterly coupon payments. This formula handles the odd first quarterly period from January 10 to April 15, 2024. The Actual/360 basis (2) is commonly used in municipal bond markets.
Key Takeaways
- ODDFPRICE is essential for accurate valuation of bonds with irregular first coupon periods, a common occurrence in fixed-income markets
- The formula requires nine parameters with careful attention to date logic and proper decimal formatting for rates and yields
- Understanding day-count basis conventions (0-4) is critical for matching market standards and ensuring pricing accuracy
- ODDFPRICE complements ODDLPRICE and PRICE functions—use the correct function based on which coupon period is irregular
- Proper data validation and testing against market prices ensures your bond valuations are reliable for investment decisions
Pro Tips
Always verify that first_coupon date is after the issue date but before the maturity date. If these dates are illogical, ODDFPRICE returns #NUM! error. Use conditional formatting to highlight date inconsistencies in your data.
Impact : Prevents calculation errors and ensures data integrity in large bond portfolios. Saves debugging time and improves formula reliability.
Create a helper column showing the days between issue and first coupon dates to understand the odd period length. This visual reference helps identify unusual bond structures and validates your data before running ODDFPRICE calculations.
Impact : Increases transparency in bond analysis, makes it easier to explain pricing to stakeholders, and helps catch data entry errors early.
Use absolute references ($) for standard parameters like redemption value and frequency that don't change across your bond list. This allows you to copy the formula down efficiently while maintaining consistent parameters.
Impact : Dramatically speeds up portfolio analysis, reduces formula complexity, and minimizes copy-paste errors when analyzing multiple bonds.
Test ODDFPRICE results against pricing data from financial data providers like Bloomberg or Reuters. Small discrepancies may indicate basis convention differences. Document which basis you're using for audit trail purposes.
Impact : Ensures your calculations align with market standards, provides confidence in valuations for reporting and compliance, and identifies any methodology differences early.
Useful Combinations
Bond Yield Analysis with ODDFYIELD
=ODDFYIELD(DATE(2024,3,20),DATE(2030,12,15),DATE(2024,3,15),DATE(2024,6,15),0.045,ODDFPRICE(...),100,2,1)Combine ODDFPRICE with ODDFYIELD to perform two-way bond analysis. First calculate the price using ODDFPRICE, then use that price to calculate the yield using ODDFYIELD. This creates a complete valuation model for odd-first-coupon bonds, allowing you to move between price and yield calculations seamlessly.
Portfolio Bond Valuation with SUM
=SUM(ODDFPRICE(A2:A100,B2:B100,C2:C100,D2:D100,E2:E100,F2:F100,G2:G100,H2:H100,I2:I100))Use ODDFPRICE within a SUM function to value an entire portfolio of bonds with odd first coupons. By applying ODDFPRICE to arrays of parameters across multiple rows, you can calculate the total portfolio value in a single formula, enabling efficient portfolio management and analysis.
Price Sensitivity Analysis with IF and ODDFPRICE
=IF(F2>0.04,ODDFPRICE(A2,B2,C2,D2,E2,F2,G2,H2,I2),ODDFPRICE(A2,B2,C2,D2,E2,0.04,G2,H2,I2))Combine ODDFPRICE with IF statements to create conditional pricing scenarios. This formula applies different yield assumptions based on market conditions, allowing for stress testing and sensitivity analysis. Useful for assessing how bond prices react to yield curve changes.
Common Errors
Cause: Date parameters are entered as text strings instead of actual date values, or rate/yield parameters are not expressed as decimals (e.g., entering 4.5 instead of 0.045).
Solution: Use DATE() function to create proper date values: =DATE(2024,3,20). Express rates as decimals: 0.045 for 4.5%. Verify all numeric parameters are numbers, not text.
Cause: Invalid parameter values such as settlement date after maturity date, frequency value other than 1, 2, or 4, basis value outside 0-4 range, or negative redemption value.
Solution: Verify settlement < maturity dates. Use only frequency values 1, 2, or 4. Ensure basis is between 0-4. Check that redemption and rate values are positive and logically sound.
Cause: Cell references in the formula point to deleted cells or incorrect worksheet references, or the first_coupon date is before the issue date.
Solution: Verify all cell references are valid and point to existing cells. Ensure first_coupon date is after or equal to the issue date. Use absolute references ($A$1) for fixed parameters to prevent reference errors when copying formulas.
Troubleshooting Checklist
- 1.Verify all date parameters are valid dates created with DATE() function or recognized date format, not text strings
- 2.Confirm settlement date is after issue date and before maturity date; first_coupon is between issue and maturity dates
- 3.Check that rate and yld parameters are expressed as decimals (0.045 not 4.5) and are logically reasonable values
- 4.Validate frequency parameter is 1, 2, or 4 only; basis parameter is 0, 1, 2, 3, or 4
- 5.Ensure redemption value is positive and typically 100 for standard bonds; verify it matches bond documentation
- 6.Compare results against independent pricing sources to confirm basis convention and calculation accuracy
Edge Cases
Settlement date equals first coupon date
Behavior: Excel treats the settlement as occurring on the coupon date after any coupon payment. The accrued interest calculation adjusts accordingly, and the price reflects the post-coupon settlement.
Solution: This is valid behavior. Verify your settlement date is intentional and check trading conventions to ensure the price accurately reflects market expectations.
Common in practice when bonds are purchased exactly on coupon dates
Very short odd first coupon period (only a few days)
Behavior: The formula calculates correctly but the price may be very sensitive to small changes in yield due to the short discount period. Rounding errors may become more apparent.
Solution: Use higher decimal precision in your calculations and verify results independently. Be aware that small yield changes produce larger price swings.
Occurs when bonds are issued very close to their first coupon date
Redemption value differs significantly from 100 (e.g., 95 or 105)
Behavior: ODDFPRICE correctly incorporates the non-standard redemption value into the present value calculation, affecting the overall bond price accordingly.
Solution: Ensure the redemption value matches the bond's actual terms. Some bonds have call features or other provisions affecting redemption value.
Callable bonds and some structured products have non-standard redemption values
Limitations
- •ODDFPRICE cannot handle bonds with odd last coupon periods—use ODDLPRICE for those cases or combine functions for bonds with both odd first and last periods
- •The function assumes semi-annual, annual, or quarterly coupon payments only (frequency 1, 2, or 4). Bonds with monthly or other irregular payment frequencies require custom calculations
- •ODDFPRICE does not account for credit risk, call options, or other embedded bond features. It provides theoretical pricing based on cash flows only
- •The formula is not available in Google Sheets, limiting cross-platform compatibility for cloud-based financial modeling and collaboration
Alternatives
Handles bonds with odd last coupon periods instead of odd first periods. Provides complementary functionality for different bond structures.
When: Use ODDLPRICE when the final coupon interval is irregular while the first coupon periods are regular. Combine with ODDFPRICE for bonds with both odd first and last periods.
