The average amount in retirement accounts for workers who have stayed with one firm is now just under $200,000, according to data from Fidelity Investments collected from more than 1.1 million workers.
To qualify for the study, a worker had to be contributing to a 401k and to must have remained with the same employer for more than 10 years.
Over that time, the 401k balance for those who qualified for the survey increased 324% to $199.800. That’s up from $47,100 a decade ago. In contrast, the S&P 500 only increased 62% over that same time frame.
Older participants are doing even better. Workers in the 55-59 age bracket who qualified for the report saw their 401k plans grow to an average of $251,700 at the end of 2012.
In the entire survey of 12 million participants, the average 401k value was $77,300. Participants have increased their savings for 15 straight quarters, according to the study.
