Lifestyle creep occurs when your standard of living starts to outpace your actual income. It’s generally related to making more without saving more — foregoing important financial goals, like establishing a proper emergency fund or saving for retirement, in lieu of buying a larger house, nicer car or luxury vacation. While it’s tempting to start spending any extra money you earn as soon as you, well, earn it, lifestyle creep can expose you and your family to a certain amount of financial risk. After all, there’s no guarantee that you’ll stay at a given income level.
