Hi,

I know about the ACCRINTM() function in Excel which returns the
Interest-Accrued
between the Issue date and the Settlement date
at a given Rate
for a given "Par" (= "amount").

What I need is *** a function *** that will return me the Rate
when I have the Issue date and the Settlement date
and the Interest-Accrued
and the Amount.

Any help appreciated.

TIA
