Participants in the study retired with median household assets of $473,000, a figure that included home equity as well as investable assets, it said. Also, Social Security made up 43 percent of household income for the recent retirees.

The survey found that 80 of the retirees track their expenses carefully and 63 percent reported they stick to a spending budget.

But the retirees were enjoying life, too, rather than just scrimping. Fifty-seven percent reported living as well as or better than they did before retiring, and 85 percent reported that they didn't need to spend as much in retirement to be satisfied with their lives.

The findings are consistent with a recent Ameriprise Financial survey that found 75 percent of the boomers it asked reporting feeling "very satisfied" in their post-work lives.

Among T. Rowe Price's other findings:

• Forty-eight percent of retirees polled have a strategic withdrawal plan and are withdrawing a median 4 percent of their portfolios.
• Thirty-three percent have an emergency fund.
• About half of those surveyed said that they had a professional financial advisor guide them through the retirement process.
• Nearly four out of five respondents reported being on track to meet their financial goals in retirement.
