ODDLPRICE Formula: Complete Guide to Calculating Odd Last Coupon Bond Prices
=ODDLPRICE(settlement, maturity, last_interest, rate, yld, redemption, frequency, [basis])The ODDLPRICE function is a specialized financial formula in Excel designed to calculate the price of a security with an odd last coupon period. This advanced function is essential for financial analysts, bond traders, and investment professionals who need to work with securities that don't follow standard coupon schedules. Unlike regular bonds that maintain consistent payment intervals, securities with odd last coupon periods require special calculation methods to determine accurate pricing. When you're dealing with complex fixed-income instruments, the standard PRICE function becomes insufficient because it assumes regular coupon periods. The ODDLPRICE function accounts for the irregular final coupon period by adjusting the present value calculations accordingly. This makes it invaluable for pricing municipal bonds, corporate bonds with special maturity dates, and other customized debt instruments that financial institutions frequently encounter in their portfolios. Understanding ODDLPRICE empowers you to make precise investment decisions, conduct accurate portfolio valuations, and ensure compliance with financial reporting standards. Whether you're evaluating bond investments, managing a treasury department, or analyzing fixed-income securities for risk assessment, mastering this formula is crucial for professional financial analysis.
Syntax & Parameters
The ODDLPRICE function syntax is: =ODDLPRICE(settlement, maturity, last_interest, rate, yld, redemption, frequency, [basis]). Each parameter serves a specific purpose in the calculation. The settlement parameter represents the security's settlement date—the date when the buyer receives the bond. The maturity parameter specifies when the bond reaches its final payment date. The last_interest parameter indicates the date of the security's last coupon payment, which is critical for identifying odd coupon periods. The rate parameter represents the security's annual coupon interest rate expressed as a decimal. The yld parameter is the security's annual yield, also expressed as a decimal. The redemption parameter specifies the redemption value per $100 face value. The frequency parameter indicates how many coupon payments occur annually: 1 for annual, 2 for semi-annual, or 4 for quarterly payments. The optional basis parameter determines the day-count convention (0=30/360, 1=actual/actual, 2=actual/360, 3=actual/365, 4=European 30/360). All date parameters must be valid Excel dates, and all numeric parameters should be positive values. Proper formatting ensures accurate calculations and prevents common errors.

Municipal Bond with Odd Last Coupon
=ODDLPRICE(DATE(2024,1,15), DATE(2024,6,30), DATE(2023,12,15), 0.045, 0.038, 100, 2, 0)This formula calculates the price of a municipal bond with an odd final coupon period. The settlement and maturity dates are close together, indicating a short-term security. The last interest date (December 15, 2023) is before the settlement date, confirming the odd coupon scenario. The semi-annual frequency (2) and 30/360 basis (0) are standard for municipal bonds.
Corporate Bond Pricing Analysis
=ODDLPRICE(DATE(2024,3,10), DATE(2024,9,15), DATE(2023,9,15), 0.052, 0.049, 100, 4, 1)This formula prices a corporate bond with quarterly coupon payments and an odd coupon period. The actual/actual basis (1) is commonly used for U.S. corporate bonds. The quarterly frequency (4) reflects four annual coupon payments. The yield (4.9%) is lower than the coupon rate (5.2%), suggesting the bond trades at a premium.
Treasury Bond with Irregular Maturity
=ODDLPRICE(DATE(2024,5,22), DATE(2024,8,20), DATE(2024,5,20), 0.050, 0.0475, 100, 2, 2)This formula calculates the price of a Treasury security with a very short odd coupon period. The last interest date is only two days before settlement, indicating the bond is trading shortly after a coupon payment. The actual/360 basis (2) is sometimes used for specific Treasury calculations. The result reflects the bond's value in this short maturity window.
Key Takeaways
- ODDLPRICE calculates bond prices when the final coupon period is irregular, essential for accurate valuation of non-standard fixed-income securities.
- Always express rates and yields as decimals (0.045 for 4.5%) and use DATE() function for dates to avoid common calculation errors.
- The frequency parameter (1, 2, 4, or 12) and basis parameter (0-4) must be set correctly for your specific bond type and market convention.
- Validate results by comparing with market data and using ODDLYIELD to back-calculate yield from your calculated price.
- ODDLPRICE is an advanced formula best suited for professional financial analysts; simpler PRICE function suffices for standard bonds with regular coupon periods.
Pro Tips
Always use the DATE() function to enter dates rather than text strings. This ensures Excel recognizes dates correctly and prevents #VALUE! errors. For example, use =DATE(2024,1,15) instead of "1/15/2024".
Impact : Prevents date-related errors and ensures consistent date handling across different regional settings and Excel versions.
Convert percentage rates to decimals by dividing by 100 or using the % operator. Enter 0.045 or 4.5% for a 4.5% rate, never enter 4.5 alone. This is the most common source of incorrect calculations.
Impact : Eliminates calculation errors that result in wildly incorrect bond prices, protecting financial decisions and portfolio valuations.
Create a reference table with standard day-count conventions for different bond types. Document which basis value (0-4) applies to each security type in your portfolio. This prevents switching between conventions accidentally.
Impact : Ensures consistency across all bond valuations and makes it easy for team members to apply the correct methodology.
Validate ODDLPRICE results by comparing with market prices or Bloomberg data when available. Use ODDLYIELD to back-calculate yield from your calculated price as a sanity check.
Impact : Provides confidence in calculations and quickly identifies when formula parameters are incorrect or when market data has changed.
Useful Combinations
Bond Yield and Price Reconciliation
=IF(ABS(ODDLYIELD(settlement, maturity, last_interest, ODDLPRICE(...), redemption, frequency, basis) - yld) < 0.0001, ODDLPRICE(...), "Mismatch")Combines ODDLPRICE with ODDLYIELD to verify price-yield consistency. This formula calculates the price using ODDLPRICE, then back-calculates the yield using ODDLYIELD. If they match within 0.01%, the calculation is confirmed; otherwise, it flags a potential error or data inconsistency.
Multi-Scenario Bond Pricing Analysis
=ODDLPRICE(settlement, maturity, last_interest, rate, IF(scenario="bull", yld*0.95, IF(scenario="bear", yld*1.05, yld)), redemption, frequency, basis)Integrates ODDLPRICE with IF statements to create scenario analysis. This formula calculates bond prices under different yield scenarios (bull market with lower yields, bear market with higher yields, or baseline). Essential for risk analysis and portfolio stress testing.
Portfolio-Weighted Bond Valuation
=SUMPRODUCT(bond_quantities, ODDLPRICE(settlement, maturity, last_interest, rate_array, yld_array, redemption_array, frequency_array, basis_array))Combines ODDLPRICE with SUMPRODUCT to value multiple bonds simultaneously. This formula calculates prices for each bond in a portfolio and multiplies by quantities, then sums for total portfolio value. Enables efficient portfolio valuation and rebalancing analysis.
Common Errors
Cause: This error occurs when parameter values are logically invalid, such as when the settlement date is after the maturity date, the last interest date is after the maturity date, or when negative values are provided for rate, yield, or redemption parameters.
Solution: Verify that settlement < maturity, last_interest < maturity, and all rate/yield/redemption values are positive. Check that dates are entered as valid Excel dates using DATE() function rather than text strings. Ensure yield and rate are expressed as decimals (0.045 for 4.5%), not percentages (4.5).
Cause: This error typically results from non-numeric values in parameters that require numbers, such as entering text instead of numeric values for rate, yield, or frequency. It can also occur when frequency is not one of the valid values (1, 2, 4) or when basis is outside the range of 0-4.
Solution: Ensure all numeric parameters contain only numbers. Verify frequency is exactly 1, 2, or 4. Check that basis parameter is between 0 and 4 inclusive. Convert any text-formatted numbers to actual numeric values. Use the VALUE() function if pulling data from text sources.
Cause: This error indicates that one or more cell references in the formula are invalid or have been deleted. This commonly happens when referenced cells are removed or when copying formulas without proper absolute/relative reference adjustments.
Solution: Verify all cell references exist and contain valid data. Use absolute references ($A$1) for fixed parameters like rate tables. Check that date cells contain actual date values, not formulas that may have errors. Rebuild the formula by manually selecting cells to ensure correct references.
Troubleshooting Checklist
- 1.Verify that settlement date is before maturity date and last_interest date is before maturity date. Date sequence errors are the most common cause of #NUM! errors.
- 2.Confirm all rate and yield parameters are expressed as decimals (0.045) not percentages (4.5). Check that all numeric values are positive and reasonable (rates typically 0-10%, yields typically 0-8%).
- 3.Ensure frequency parameter is exactly 1, 2, 4, or 12, and basis parameter is between 0 and 4. Any other values will produce #VALUE! errors.
- 4.Check that all date cell references exist and contain valid dates. Use DATE() function rather than text strings. Verify cell references haven't been deleted or moved.
- 5.Confirm redemption value is per $100 face value (typically $100, but may be different for some securities). Verify this matches your data source and bond prospectus.
- 6.Test the formula with known bond data or market prices to validate results. Use ODDLYIELD to back-calculate and confirm the price is reasonable for the given yield.
Edge Cases
Settlement date equals last interest date
Behavior: The formula treats this as a bond with zero accrued interest. The calculation proceeds normally, but the accrued interest component is minimal.
Solution: This is typically valid; no error occurs. However, verify this matches your business logic for the specific security.
This scenario is uncommon but valid for bonds settling exactly on a coupon payment date.
Maturity date is very close to settlement date (less than one month)
Behavior: The formula calculates correctly but produces prices very close to the redemption value. The odd coupon period is extremely short.
Solution: Verify the dates are correct. Such short maturities are unusual but valid for money market instruments or short-term bonds.
Results are mathematically correct but represent high-risk, short-duration securities.
Yield is significantly higher than coupon rate (deep discount bond)
Behavior: ODDLPRICE returns a price substantially below $100 per $100 face value, reflecting the bond's discount due to market yield changes.
Solution: This is correct behavior. Verify that both yield and coupon rate are accurate. Such scenarios are common in rising interest rate environments.
Mathematically valid; represents bonds trading at significant discounts to par value.
Limitations
- •ODDLPRICE handles only odd last coupon periods; for odd first periods, use ODDFPRICE. For bonds with both odd first and last periods, more complex calculations are required.
- •The function assumes a single odd period; bonds with multiple irregular coupon intervals require alternative valuation methods or manual calculation adjustments.
- •ODDLPRICE does not account for credit risk, call options, or other embedded derivatives. It provides theoretical pricing based solely on the stated parameters.
- •The formula requires precise date and rate inputs; small data entry errors can significantly impact results. Validation against market prices is essential for production use.
Alternatives
Simpler syntax and faster calculation for regular coupon bonds without odd periods. More widely known and easier for beginners to understand.
When: Use PRICE when working with standard bonds that have regular coupon periods. PRICE is sufficient for most corporate and government bonds with conventional payment schedules.
Handles bonds with odd first coupon periods instead of odd last periods. Complements ODDLPRICE for comprehensive odd-period bond pricing.
When: Use ODDFPRICE when the irregular coupon period occurs at the beginning of the bond's life rather than at maturity. Some newly issued bonds may have odd first periods.
Provides complete flexibility and transparency for custom bond pricing scenarios. Allows for step-by-step control over each calculation component.
When: Use PV-based calculations for highly customized bonds or when you need to understand and audit every calculation step. Useful for educational purposes or when ODDLPRICE limitations arise.
