Understanding Interest charges - Halifax

Daneeka

Halifax recently jazzed up their mortgage section on the Online Banking so I've been looking at it more and trying to figure it all out.

We are on a fixed rate of 6.19% until Nov 2013. I noticed today that the interest we were charged for April was about £100 more than the interest we were charged in March.

I'll admit that I don't really understand mortgages (although I'm trying to learn!) but my understanding is that if you pay X amount each month, there is less loan to pay and thus less money to be charged interest on.

Is this just some sort of weird end of April charge or is there something funny going on?

Details:
Term: 25y 7m
Rate: 6.19%
Balance: £84,218.24
Monthly payment: £547.91
Interest charged 31 Mar: £325.42
Interest charged 30 Apr £427.93

Thank you for you help

March's interest shown online was only from 9th March - 1st April. (when they migrated their system)

April's interest was for the full month, hence the difference.

Source: Same thing happened on my mortgage, so I called them to ask why.
