How Much of Your Raise Did Lifestyle Inflation Eat?

Lifestyle inflation — also called lifestyle creep — is the tendency for spending to rise in proportion to income, so that higher earnings produce no improvement in savings rate or wealth accumulation. Get a raise, upgrade the apartment. Get a bigger raise, upgrade the car, the restaurants, the wardrobe. Each upgrade feels reasonable; the aggregate effect is that income gains are absorbed rather than compounded. The mechanism is subtle precisely because each individual spending increase is rational. You earn more, so a nicer apartment is affordable. You work harder, so regular restaurant meals feel earned. You can afford the upgrade now, so deferring it feels unnecessarily austere. But collectively, these rational-seeming choices can consume the entire benefit of years of income growth, leaving the financial position unchanged despite dramatically higher earnings. This Lifestyle Inflation Calculator compares your income and spending before and after a raise or lifestyle change. It calculates your inflation rate (what percentage of the income gain was absorbed by higher spending), your risk tier (Healthy, Moderate, High, or Critical), the change in your savings rate, and the 10-year wealth gap between your actual trajectory and what you could have accumulated with 0% lifestyle inflation. An optional category breakdown shows exactly where spending increased most.
