Current U.S. workers expect that it will take them seven years longer than current retirees to save for their retirement lives, according to a new report from HSBC.

Current American retirees spent 28 years saving for their after-work lives, but future retirees expect that they’ll need to save for 35 years, according to “Generations and Journeys,” which is based on the views of more than 18,000 people in 17 countries.

The findings for current U.S. workers mirror the average additional saving time — seven years — expected by similar populations of all of the nations examined by the banking and financial services organization. The United States, however, exceeded the average number of years that current retirees worldwide saved for retirement (23) as well as the average number of years that workers worldwide expect to need to save for retirement (30).

HSBC’s research also found that, worldwide, 24% of workers, including 12% of those aged 60 or more years and 8% of those aged 70 or more, still have not started saving for retirement. In the United States, however, “only” 14% of workers have not begun saving for retirement.

The findings are based on nationally representative surveys of people of aged 25 or more years who are working or retired.
