How do I stop lifestyle creep from eating every raise I get?

Lifestyle creep is the slow rise in spending that follows rising income, and it is why higher earners can still feel broke. The most effective defense is to decide in advance where a raise goes before it hits your account. A useful rule is to bank at least half of every raise, splitting it toward retirement, savings, or debt, and let yourself enjoy the rest. Because 401(k) contributions are percentage-based, bumping your contribution rate right when a raise lands captures more savings automatically and painlessly. Keep your fixed costs, especially housing and cars, flat even as pay grows, since these anchor your whole cost of living. The goal is not deprivation but making sure income gains translate into wealth rather than just a bigger monthly nut.
