Views – Adding values in a column and displaying result as a total

I would like to display a column total (under the column) and cannot find a solution from previous posts.

Each selected post has a field "hire-fee" so my list looks like:

Item 1 12.50
Item 2 12.50
Item 3 6.25

I just want to add the line under the item list:

=========
Total 31.50

This type of column totalling would be most useful in Views – particularly if totals could be applied to multiple columns.

Thanks
Tony
