U.S. credit card debt decreased slightly in May, down .2% to $5,637 from April 2012, according to CreditKarma.com's U.S. Credit Score Climate Report released Wednesday.

Student loan debt is also down, falling 2% year-to-year to $29,088, with residents in Nevada ($26,456) and New Mexico ($25,332) boasting the biggest decreases at 12% and 11% respectively.

“The Obama administration is currently trying to make it easier on consumers to manage student debt, capping repayments for federal Stafford loans at 10 instead of 15% of disposable income for those making on time payments,” says Ken Lin, CEO of CreditKarma.com. “While this can help consumers manage debt, this means that the average student loan debt will likely increase as students take more time to pay back loans.”

Credit scores fell three points nationwide from the previous month to 656. In May 2012, the average consumer with an account had $167,485 in home mortgage debt and $46,499 in home equity debt.

Other key findings include:

· Auto loan debt saw the biggest percentage increase on a monthly and yearly basis, increasing by 1% and 3.1% respectively to $15,691. From a year ago, Wyoming ($19,847) and Rhode Island ($13,533) added to their auto debt the most at 7%.

· Delaware was the only state to increase its credit score from last month - up one point to 649. Alaska (658) and South Dakota (657) saw their credit scores drop the most at five points, followed by Iowa (658), Kansas (651), New Mexico (648), Mississippi (621), Texas (645) and Wyoming (646) at four points.

· Since April, Rhode Island (5%), Arizona (3%) and Alabama (3%) paid down their credit card debt the most while North Dakota (3%), New Hampshire (3%) and New Mexico (4%) added the most debt.
