Why does my savings rate matter more than how much I earn?

Two people earning the same salary can end up in wildly different places, and the difference is usually the savings rate, the share of income you keep and invest. A high earner who spends nearly everything builds little wealth, while a moderate earner saving 20% or more steadily accumulates it, because wealth comes from the gap between income and spending, compounded over time. Raising income helps only if the extra money is saved rather than absorbed by lifestyle creep. That's why capping spending growth when you get raises is so powerful. Focus on nudging your savings rate up a few percentage points at a time, ideally by automating each raise into savings before you adjust to it. Over decades, the savings rate, not the paycheck, does most of the heavy lifting.
