No matter how you calculate it, retirement plan assets represent a significant percentage of Americans' wealth — growing 3.9% in the third quarter and reaching $21.7 trillion, according to the ICI. Of all sectors, IRAs grew at the fastest rate, 4.6%, reaching $6 trillion, followed by DC plans at 4.4% and $5.56 trillion; 401(k) plans grew 5%, reaching $4 trillion. Combined, DC plans and IRAs represent 53.2% of all retirement assets, compared with 15.9% ($2.9 trillion) in private DB plans.
TDFs continue to grow as well: they grew 6.1% in Q3 to $573 billion; 70% of TDFs are in DC plans. Overall, mutual funds now account for 59% of all DC assets, at $3.3 trillion.
