When I first joined TimeValue Software, it took me a while to understand the difference between Daily (compounding) and Exact Days. Both methods calculate interest each day but that is where the similarity ends.

Occasionally, we get a customer that has a unique situation where they have to do daily payments. Sometimes they are only during the business week and sometimes they are 7 days a week.  This is a calculation that you can do in TValue but it takes a little bit of creativity to do it.
