You will have to read my new report to find out the full answer. Although PFM solutions have been in existence for several years, adoption is pitiful. To give you an idea, only 3.8% of users across large banks and software vendors have been active in the last 30 days. It's a horrific statistic, and it's no wonder so many financial institutions are reluctant to move into the PFM realm. Here are a few examples of why adoption is so shoddy:

• Poor overall online banking user experience and customization capabilities. See this post for more info and examples
• Assuming PFM can serve the mass market (e.g. not everyone wants to or needs to budget. What a wealthy person needs or is willing to do online is not the same as what someone in debt requires or is willing to do).
• Poor auto categorization accuracy
• Lack of relevant and targeted user education
• The list goes on and on

The good news is that adoption is expected to climb. The report has all kinds of forecasts that provide insight as to where PFM is headed. It also delves into qualitative details as to what is required by financial institutions in order to make PFM viable. There's also a whole discussion about tablets and their role and potential in online banking and PFM.
