If you’re unable to pay all of your bills on time, “cushion the blow to your credit score by defaulting on just one account. There is a component in the FICO score called 'prevalence,'" says John Ulzheimer, president of consumer education at SmartCredit.com. "That means having five collections is worse than having one." He recommends that you “let the account with the highest monthly payment fall behind to free up more money every month to pay your other debt obligations.”
Those with poor credit or no credit can obtain a low credit limit secured credit card (by putting up a security deposit). This is reported to the credit bureaus as a regular credit card and allows you to build a positive payment history quickly. Eventually, the credit card company (and others) will offer you a higher traditional credit limit without the security.
Next, estimate your monthly spending habits for other expenses such as gas, groceries and entertainment. Create a limit, based on your income, of what you can spend in each of the different categories of expenses. For example, if you tend to spend $400 a month on groceries, try to stick to $300 a month on groceries by making changes like buying generic brands, using coupons, and resisting impulse purchases.
