Hey, great question. This is Jason (Tally co-founder). Credit card APRs are massively inflated. Here are two points to consider:

A. There is a 500% difference in the likelihood of someone paying back a loan with a 760 FICO score vs someone with a 660 FICO score, but only an 8% difference in APR.

B. "the credit card business continues to be the most profitable bank lending business, with returns more than four times higher than the average return on assets." - Richard Cordray, Director of the CFPB (December 2015)

The bottom line is that banks are significantly overcharging consumers AND have high fixed costs. Because of the technology Tally has built, our cost structure is an order of magnitude lower than banks. This means we can save customers money and be profitable as a business.
