How Long Does $2.5M Last in Retirement? (Ad) Having $2.5 million saved puts you ahead of most Americans, but how long it lasts depends on the decisions you make with it. Using the 4% rule as a benchmark, that balance could translate to about $100,000 in year one, adjusted upward for inflation each year after. But the 4% rule has potential downsides and may not fit every portfolio. A financial advisor can help size and structure a retirement budget around your income sources, taxes, and goals.
