I think this is the big question. I really love this idea, because too many people are struggling unnecessarily because they don't realise the true impact of credit card debt. Having something that clearly shows them this impact is a great idea. But I find it hard to believe they will seek something like this out, so it's going to be tricky to reach them.

I was thinking about the very problem yesterday, and wondered if it would be worthwhile requiring information like this to appear on all credit card statements. Instead of just highlighting a minimum payment, what if the statements also had to outline the impact of higher payments somehow? It could be the only reliable way to get the information to the people that could benefit most.
