Milestone Timeline

See exactly how long each $100K milestone takes and watch them accelerate as compound growth kicks in.

How Milestone Timeline Works

The calculator runs a month-by-month compound growth simulation, tracking when your balance crosses each milestone. You see the exact years for each increment and how much faster each one arrives.

  • Month-by-month compound growth simulation
  • Tracks contributions vs investment returns at each milestone
  • Shows acceleration percentage between milestones
  • Adjustable milestone increments ($25K, $50K, $100K, $250K)

Why Milestones Accelerate

Charlie Munger said "the first $100,000 is the hardest" because early on, your savings do most of the work. But as your balance grows, compound returns contribute more and more — eventually dwarfing your contributions.

  • Early milestones are savings-dominated (you contribute most of the growth)
  • Later milestones are returns-dominated (your money works harder than you)
  • At $1M with 7% returns, your portfolio earns $70K/year on its own
