I would not take action to get a credit card if I was unsure about my ability to pay off my credit card debt. Instead, I spend more time considering the following:
1. Can my income cover my credit card expenses?
2. Do my expenses exceed my income level?
3. How much savings do I have, and will using a credit card not overburden my finances?
4. Can I pay off the loan completely before the end of the credit card term?
5. Can I afford the processing and other fees incurred by credit card transactions?
Before considering applying for a credit card, make sure you have the ability to pay off the balance, otherwise it will create more stress.
