Lifestyle creep.

In plain English

Lifestyle creep, sometimes called lifestyle inflation, is what happens when your spending rises to match a growing income. A raise or bonus quietly turns into a bigger apartment, a newer car, and more subscriptions, so you feel no richer and save no more than before. It is not about one big splurge but a slow ratcheting up of what feels normal. The antidote is to decide in advance where a raise goes, sending part of it to savings before it can be absorbed.

01Why it matters

Lifestyle creep is why many people earn far more over time yet never build wealth, because each raise is spent rather than saved.

02The math, step by step

You get a 500 dollar-a-month raise and, within a year, a nicer apartment and a car upgrade eat all of it. Your income rose, but your savings did not.
