APR just means annual percentage rate
While a merchant might view it as a loan rate, it's just a mathematical equation. It's used also for annual rate for earned for investments as well.

(Okay, so Breakout offers loans, but whatever)

On a 30-year mortgage, you can present the factor rate in as well. For a $60,000 mortgage at 4.9% APR, you're paying a factor rate of a 1.91 factor!! Outrageous! And at 3.8% APR, that's a factor of 1.67!!

What math you do to get a 1.91 from a 4.9% apr?? 4.9%apr=1.049 factor... now do a 12 month MCA at 1.40 over 30 years and tell me total factor??
