The Power of Starting Early

Consider two savers, both earning $75,000 and contributing 6% (with a 6% employer match): Alice starts at 25 and retires at 65. Bob starts at 35 and retires at 65. Assuming 7% annual returns:

  • Alice (40 years): approximately $1.4 million
  • Bob (30 years): approximately $680,000

Ten fewer years costs Bob over half a million dollars in retirement savings: demonstrating why starting as early as possible, even with small contributions, is the single most impactful 401k decision.
