Behind the numbers (from WSJ):

Without comparison shopping, consumers don’t know the difference. And in the absence of that competitive pressure, lenders have no incentive to offer similar borrowers comparable rates. As a result, one borrower may pay thousands more than another, even when the two have virtually identical credit scores, commensurate debt and are buying the same thing at the same time in the same place.

“Most people think prices are roughly the same,” said Sergei Koulayev, an economist with the Consumer Financial Protection Bureau. “The differences are large.”

...The average difference in car loans is 1.3 percentage points, according to researchers at MIT and Brigham Young University. For the typical car loan, the difference would be like paying $1,300 more on the purchase price.

After volunteering in 2010 to create and teach a personal finance program at Eastside College Prep in East Palo Alto, Tim saw firsthand the impact of an engaging and activity-based curriculum, which inspired him to start a new non-profit, Next Gen Personal Finance.
