Monthly or Annual interest?

[squips]

Amount Deposited Gross Per Annum
paid Annually AER*
6.30%

OR

Amount Deposited Gross Per Annum
paid Monthly AER*
6.13%

How can I work out which is best for my savings?

The AER is your annual equivalent rate so you get a higher return by taking the paid Annually option.

I think it works out the same - if you leave the monthly interest in the account you will be earning interest on that as well.
