Thanks to MyMoneyBlog, there is a new online tool to calculate just how much money you can make via the 0% APR balance transfer route. The 0% APR Balance Transfer Profit Calculator Tool is a simple way to calculate money earned on potential 0% balance transfer options. Note however that this tool allots no field for potential balance transfer fees (even though a large percentage of credit card companies charge them, usually at a rate of 3% or so). Be sure to add this into any transaction that you calculate. Read the post for more information.
