What will $1M grow to in 40 years?

$1,000,000 invested for 40 years at a 7% average annual return grows to about $14,974,458. That's roughly 15× your starting amount, all from compounding.

The growth comes entirely from compounding. Each year's return earns returns of its own. At a 7% average annual return (Rightmont's long-horizon diversified assumption), a one-time $1,000,000 becomes about $14,974,458 after 40 years, with no further contributions.

This is nominal growth, before inflation. Over 40 years, inflation erodes purchasing power, so the real spending value is lower. That's the reason to plan in present-day dollars, and Rightmont's projections show both.
