If you transfer your debt and use your card responsibly to pay off your balance before the intro period ends, then there is no trap associated with the 0% APR period. But, if you neglect making payments and end up with a balance post-intro period, you can easily fall into a trap of high debt — similar to the one you left when you transferred the balance. As a rule of thumb, use the intro 0% APR period to your advantage and pay off ALL your debt before it ends, otherwise you’ll start to accumulate high interest charges.
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.
