Hi - I am trying to work out how much interest I have to pay for a loan I have. The interest gets applied every month on the 2nd.

I want to be able to input

Cell A1: First date for example 14/06/2011
Cell B1: Second date for example 04/08/2011

Cell C1: Result 2

Hope this makes sense; I have been banging my head on the table for the last two days trying to figure it out!
