If your data is in A1:A4 (A1 = start date; A4 = annual interest rate):

=FV(A4/2, DATEDIF(A1,A2,"m")/2, 0, -A3) - A3

That formula assumes that start and end dates are the same day of the month.
Caveat emptor when the day of the month is 31, or the start or end date is
Feb and the day of the month is 29 or larger.


how can we calculate witouht any fractional error if we follow
30/360 day counting covention.

That sounds suspiciously like the example in the ACCINTR help page.

Are you asking for help using ACCINTR? If so, what specifically don't you
understand?

Note: With bonds, the first semi-annual interest payment is not always 6
months after the "start date" (i.e. when you purchased the bond). So
technically, you need one more piece of data.
