Investors Are Saving at Least 10% a Year for Retirement: Schroders

But Schiffman added a cautionary note: "If investors start taking their benefits as soon as they qualify for Social Security, they could be leaving money on the table. If they are able to delay by just a few years, they could enjoy higher levels of annual Social Security income for the rest of their lives. Judging by their expectations about spending, they may need it."

Schroders conducted the online survey in the second quarter among some 23,000 investors from 32 locations around the globe. These included 1,500 U.S. respondents who said they would be investing at least $10,000 in the next 12 months and who had made changes to their investments within the last 10 years.

According to the survey, 37% of investors said they expected their working hours per week to stay the same or increase in retirement, and 56% said their spending habits in retirement also would increase or remain the same as they are today.

This comes close to what happened with investors in the survey who were already retired. Fifty-one percent of retirees said their spending had increased or stayed the same, and 31% said the same about their working hours.

In another finding, 50% of retired investors reported that they had added high-risk investments to their portfolios when the markets hit extreme volatility in February and March at the onset of the pandemic.

Another 28% of retirees stayed the course, making no changes to their portfolios.
