The average balance in a Fidelity IRA rose 15% in the second quarter to $92,600 -- an all-time high.
In the same period, the average balance in a Fidelity 401(k) also set a record, up nearly 13% to $91,000.
The surging stock market drove most of the gains. Contributions from employees and employers accounted for about a quarter.
The numbers look better if you've been working a while: The balance for employees who have been in a 401(k) for 10 years rose 15% a year over the past decade to $246,200.
Still, even that balance is probably not enough to retire on. Fidelity recommends ultimately saving eight times your yearly salary.
Even more sobering, a 2013 study by the Employee Benefit Research Institute found that nearly half of all workers had less than $10,000 saved.
