Compare time, not just totals.

These scenarios use annual compounding and end-of-year contributions. They illustrate tradeoffs; they do not predict investment returns.

Investor A contributes for 10 years, then coasts. Investor B starts at year 10 and contributes through year 40. At 0.1%, A's early coasting path leads in this scenario.

A final value (coasts after 10y)$631,046
B final value (grinds 30y)$566,765
A total contributed$60,000
B total contributed$180,000
A/B final value ratio1.11x
