Consumers' IRA contributions have hit record levels—but are the extra funds enough to save for retirement?

Account-holders contributed an average $4,150 during tax year 2013, an all-time high, according to a new report from Fidelity Investments. That tally represents a 5.7 percent increase from 2012. (See chart below for a breakdown of average contributions by age.)

"Investors are putting their money where their mouth is by committing to save more for retirement," said Kevin Hevert, vice president of Fidelity Investments.

The report comes on the heels of another Fidelity study last week, showing that increased contributions and the bull market pushed during the second quarter of this year. Average 401(k) balances reached $91,000, up 12.9 percent from a year earlier, while the average IRA balance was $92,600, a 14.7 percent increase.

Although it's a bright spot that consumers are saving more, investors still have a long way to go. Even contributing the maximum $5,500 to an IRA ($6,500 for consumers age 50 and older) won't be enough for many consumers to have a comfortable retirement, said Sam McPherson, a certified financial planner based in Brooklyn, N.Y. Failing to save is a lost opportunity.
