Deal with Your Debt. Few people get far in adulthood without accumulating some form of debt: credit cards, student loans, car loans, and mortgage payments are common. In fact, debt can be a good thing (who has the money to buy a house outright?), but the key is to use them wisely. Credit cards and other forms of debt can be an essential part of your financial toolbox, but you must exercise care when using these tools. Understanding the difference between good debt and bad debt will go a long way in making sure you create and maintain a good credit history.
If you're self_employed, your after_tax income equals your gross income less your business expenses, such as the cost of your laptop or airfare to conferences, as well as the amount you set aside for taxes.
