Lifestyle creep, also known as lifestyle inflation, is something that can happen before you even realize it. As your income increases so does your lifestyle.
Living on a budget is living on a predetermined set of money or set income you have. The budget you create acts as a framework or guideline to determine how much you can spend, what you can afford, and how much money you have available in order to pay for food, rent, drinks, or any other necessities you may have.
