Starts 32, never stops

$307,181

paid in $79,200 over 33 years

The early starter wins by $34,628— while paying in $55,200 less. They just gave the money more time. This is the only advantage that belongs entirely to the young, and it cannot be bought back later.

What a 1% fee costsPaying 1% a year instead of 0.05% would take about $162,064 out of the same contributions by age 65. The fee is the one variable you control with certainty.

A fixed annual return is a simplification — real markets don’t return the same amount every year and past performance guarantees nothing. This shows the shape of the thing. It is not a forecast and it is not financial advice.
