Teaser Rate Offer CalculatorI got one of those teaser offers from Bank of America so I thought, “wouldn’t it be nice to have an application that would tell you whether using the offer to pay off another credit card would be worthwhile?” Rather than go search the internet to find one, I decided it would be more fun to write it myself. So, here it is:

So, here’s how it works: You enter the line of credit available on the offer, the fee for the advance and the teaser interest rate in the “Available Calculations”. Then, you enter the payoff amount, interest rate and the number of months the offer runs (ie. Payoff in May and offer runs through December = 8 months). Once you have all this data entered in the boxes, click the “Calc Savings” button (or press Ctrl + s). If the payoff is greater than the line of credit, the line of credit is used in the calculations. If the payoff is less than the line of credit, the payoff is used.
