The average account balance of participants in 401(k) plans record-kept by Fidelity Investments rose 5.7% in the fourth quarter to $64,200, up 28% from a year earlier.
The median personal rate of return in 2009 was nearly 27%, just above the 26% total return for the S&P 500, according to the Fidelity report.
Fidelity’s analysis was based on 11 million participants in more than 17,000 corporate defined contribution plans that are record-keeping clients of Fidelity, spokesman Michael Shamrell confirmed in an interview.
Also, among 766,000 plan participants who held their accounts continuously for 10 years through the end of 2009, the average account balance increased 149% to $163,900 over that 10-year span. The gain was due to a combination of “continued participant and employer contributions, dollar-cost averaging and market returns,” Fidelity said in a news release on the report.
