Why would anyone want to pay off their debts in a way other than “highest interest” first?
It may be the case that some of your debts have a flat regular fee in addition to the interest, which will go away when the debt is completely paid. For example, my mortgage has an approximately $400/year "package fee" as well as its (quite low) interest. When I finish paying the mortgage, I won't have to pay that fee anymore, so it is theoretically possible that spending extra money on paying off my mortgage would be better than spending it on paying off some other debt. I think it's unlikely that it would actually ever be my optimal move in practice, but the point is, there may be an advantage, financial or otherwise, to getting rid of a particular debt, other than merely removing the burden of interest. Those are special situations, though, and in the majority of cases, starting with the highest interest loan will be the right move.
