More than half of working baby boomers say they’re likely to retire at or before age 65. But almost half of those same boomers -- either with or without a pension -- also say they’ll retire with debt still on their shoulders, according to a Fidelity Investments survey released today.

When it comes to preparing for retirement, hindsight is 20-20. Twenty percent of baby boomers who have already retired said they had not done any financial planning beforehand, according to Fidelity. Fifty percent of them said they only started a year or more beforehand.

Nearly half of all boomers – regardless of whether they expect to retire with a pension -- anticipate retiring with debt from some of life’s typical demands: mortgage payments, followed by credit cards, car payments and student loans for themselves, a spouse or their children.

Fidelity polled 1,018 baby boomers either working in or recently retired from corporate jobs to gauge their retirement readiness and the role of employer-sponsored benefits in their lives. This comes at a time when more than 3 million boomers are turning 65 each year.

“Even the small population of baby boomers who actually receive a pension payout today feel they should have saved earlier than they did for their income in retirement,” says Wendy Foster, a senior vice president at Fidelity Investments, in a statement. “Saving more aggressively and planning well ahead of your expected retirement date becomes even more critical for the majority of Americans, particularly younger workers, without traditional pensions.”

Also, regardless of whether they have access to pension payments in retirement, seven out of 10 retired boomers said they wished they had done more to save for retirement during their working years.

Fidelity Investments is an international provider of financial services, with assets under administration of $3.8 trillion, including managed assets of $1.6 trillion, as of October 31.
