What will $100k grow to in 20 years?

$100,000 invested for 20 years at a 7% average annual return grows to about $386,968. That's roughly 4× 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 $100,000 becomes about $386,968 after 20 years, with no further contributions.

This is nominal growth, before inflation. Over 20 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.
