HP12c Credit Card Payment Calculation

[acapde]

Hi,

I doubt that the built-in TVM function of any business/financial calculator can solve that, at least presented that way.

Being the HP12 a programmable calculator, I would program a loop that calculates each time the payment and the interest added to the capital till the capital is 0 (or less than zero), the number of iterations is the number of periods required to pay the debt off… knowing the credit card companies, it would likely be an infinite loop

This is the way I’d do it, however there might be better ways of achieving it.

Hope it helps.
