Credit Card companies have a new pitch - "0% Interest on Balance Purchases & Transfers Until XX/1/2012". The idea is to give you credit, with no interest on the outstanding balance for 12 months. And, as an added bonus, the offering company will even take your balance, on which you are being charged 20% from another card, and let you move it, AT NO INTEREST, for the same period. Sounds too good to be true? It is!!First, all of these offers looked at closely, contain a "nominal" fee for making the balance transfer - like 5% of the amount of the transfer. That is a one time immediate capture fee, meaning they get paid by increasing your balance by that 5%. One could say that it's still a bargain because it's only 5% instead of 20%. However, if you pay the entire balance off in 3 months, you paid a rate of 20% annualized, versus paying the old card 20% balance off in 3 months which has the same effective rate. Well, same rate so you are no worse off than if you kept the old card. WRONG!That 5% fee get added to your principal balance because it's a fee, not interest. So, instead of paying interest on $5,000 (which is the amount transferred in this example) you pay interest on $5,250.
