Easy way to calculate Interest Expense FRA

CFA Level I
#1

I was wondering if there was an easy way to calculate total Interest Expense over the period of bond, and also Interest Expense pertaining to “n’th period”. The one I am using currently involves making a table sort of format. Edit: Never Mind I got one.

For what? A bond? A lease? A mortgage?

For a bond. I did get one. But what is your technique to find it quickly ?
