Excel ODDLYIELD Function

Excel ODDLYIELD function

The Excel ODDLYIELD function returns the yield of a security with an odd (irregular) last period.

Get yield of security with odd last period
Return value 
Yield as percentage
=ODDLYIELD (sd, md, ld, rate, pr, redem, freq, [basis])
  • sd - Settlement date of the security.
  • md - Maturity date of the security.
  • ld - Last interest date of security.
  • rate - Interest rate of security.
  • pr - Price per $100 face value.
  • redem - Redemption value per $100 face value.
  • freq - Coupon payments per year (annual = 1, semiannual = 2; quarterly = 4).
  • basis - [optional] Day count basis (see below, default =0).
Usage notes 

Some bonds have an irregular first or last period, so interest payments don't fit a normal schedule. To calculate the yield of a bond with an irregular last period, you can use the ODDLYIELD function. The ODDLYIELD function returns the yield of a security with a short or long last period as a percentage.


In the example shown, we want to calculate the yield of a bond with a last interest date of 15-Oct-2017 and a settlement date of 5-Feb-2018. The bond matures on 15-Jun-2018, and pays a coupon rate of 5%. Payments are semi-annual, the day count basis is US 30/360, and the redemption value is $100. In the example shown, the formula in F5 is:


With these inputs, the ODDLYIELD function returns 6.32%, with percentage number format applied.

Entering dates

In Excel, dates are serial numbers. Generally, the best way to enter valid dates is to use cell references, as shown in the example. To enter valid dates directly inside a function, the DATE function is the best option. To illustrate, the formula below has all values hardcoded, with the DATE function used to enter the three required dates:



The basis argument controls how days are counted. The ODDLYIELD function allows 5 options (0-4) and defaults to zero, which specifies US 30/360 basis. This article on wikipedia provides a detailed explanation of available conventions.

Basis Day count
0 or omitted US (NASD) 30/360
1 Actual/actual
2 Actual/360
3 Actual/365
4 European 30/360


  • In Excel, dates are serial numbers
  • All dates, plus frequency and basis, are truncated to integers.
  • If any dates are invalid (i.e. not actually dates) ODDLYIELD returns #VALUE!
  • ODDLYIELD returns #NUM when:
    • (maturity > settlement > last_interest) is NOT true
    • Rate < 0 or pr <= 0
    • Basis is out-of-range
