Reading a compound growth projection honestly

The striking thing about a long projection is not the final number but the split. Early on, almost all of the balance is money you contributed. Somewhere in the second decade growth overtakes contributions, and after that the line pulls away from the dashed one on its own.

The inflation-adjusted figure matters more than the headline. Most calculators quote the nominal balance, which flatters a 30-year projection considerably — at 2% inflation, money loses about 45% of its purchasing power over that span. The number in today's money is the one you can actually reason about.

A projection assumes a steady annual return, and no real portfolio delivers one. The same average arrived at through a different sequence of good and bad years produces a different result, especially once you are withdrawing. Use it to compare choices, not to predict a balance.
