What is the difference between base interest rate and APR?
as other have said APR is the way to compare APR is the cost of credit expressed as a yearly rate. The APR includes the interest rate, points, broker fees, and certain other credit charges that. base interest rate is very miss leading (in my view it should be band) it can include fees and also you can be paying the 3.6 on the full amount for the lifetime of the loan, where APR is only what you still owe.
