Hello,

Ok just a couple of simple questions, that I have:

How do you calculate daily interest? I have seen a few people list this and I am not sure how to work it out.

Also

What does, "DH", "OH", "DS", "DD" mean? (I think OH is other half)

Thank you

Daily interest at a given point in time is
(current mortgage balance * interest rate)/(days in year * 100)

eg for 3% interest rate on 100,000, given about 365.25 days per year, the daily rate is

(100000*3)/(36525)=8.21.

As for your second question, I always assumed they meant darling husband/son/daughter.
