Interest rates on credit cards are closely tied to the prime rate, so you'll likely see decreases near .25% on interest rates.
Americans now owe about $870 billion in credit card debt, as Business Insider's Gina Heeb reports, and Value Penguin estimates that the average American household has about $5,700 worth of credit card debt. With interest rates low, now is a good time to start dealing with it.
With this decrease, there's an opportunity to pay off credit card debts at a lower interest rate, or consolidate debt and lock in that lower interest rate.
