The exact number of points anyone’s credit score may drop for negative credit behaviors or improve with positive behaviors varies because everyone’s credit file is made up of a different combination of several factors.

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.
