Let's say you have two loans.  One is a revolver and the other is a mortgage with an amortization schedule. 

I know to accrue the interest from the revolver that has been incurred but not been paid at the end of a fiscal period.  But what about the mortgage? 

I have the mortgage principal in an account but do I also have to book accrued interest for it ?  Payment is due the tenth of every month.  Would I also book 10 days of interest to an accrued interest account?
