The single most effective move with a raise is to save it before you adjust to it. When your take-home hasn't yet risen in your mind, redirecting the increase — into a 401(k), an IRA, extra debt payments, or savings — costs you nothing in felt lifestyle. This is the antidote to lifestyle inflation, the tendency for spending to rise to match every income bump, which is why some high earners never build wealth.
A concrete tactic: each time you get a raise, increase your retirement contribution rate by a chunk of it. Over a career, this quietly moves you from saving too little to saving plenty, without a single painful budget cut. The raise you never see is the one that builds the most wealth — because it compounds for decades instead of funding a bigger everyday life.
