If you cash in your IRA early, you will not only pay taxes on it (unless it is a ROTH), you also pay a 10% early withdrawal penalty. That means that money is not going to go very far. Before you use your retirement money to pay off consumer debt, I would suggest you at least talk with a reputable credit counseling agency to see if there’s a way to get out of debt without using this money that you will no doubt need when you do retire.
Happily, consumer protection laws now require credit card issuers to disclose the precise length of time that the "minimum payment plan" takes to work for each customer. When you get your next credit card bill, look for the box that says something like "If you make only the minimum payment on this balance, you will pay a total of 'X' dollars and take 'Y' years to pay off your balance."
A debt management plan sets up a payment schedule for you to repay your debts, with the goal of helping creditors receive the money owed to them and ultimately improving your financial and credit standing. By voluntary agreement, you deposit funds with your credit counseling agency each month, who sends those funds directly to your creditors. It usually takes 3-5 years to complete payments under a debt management program, after which you may be able to reestablish credit.
