These are the most common disruptions seniors face in retirement

Many Americans see retirement first as a process of saving enough money and, when that goal is met, finally settling into rest and relaxation in their later years.

But several challenges often threaten to derail that plan, a new survey found.

Roughly half of today’s retirees (48%) say their retirement has involved even more surprises and challenges than expected, according to a recent Edward Jones survey of over 12,000 North American adults across five generations.

Five situations retirees often face that can majorly disrupt their retirement wellbeing — including their finances — are the death of a family member or close friend, personal health issues, a partner or spouse’s health challenges, financial setbacks, and retirement itself.

Anticipating those challenges may help those planning for retirement also include preparations for those common setbacks — at least financially.

"We've said, 'OK, we are going to really dive in and understand what retirement means to people today," Lena Haas, head of wealth management advice and solutions at Edward Jones, told Yahoo Finance. "How do they feel overall? What derails them? What helps them be successful?'"

Here are the big takeaways.

Having a family member or close friend die

The most common disruption is having a family member or close friend die, cited by 42% of people in the study. For those who lost their spouse/partner, 77% said it was an extremely disruptive event.

That's not surprising, Haas said.

Many couples often plan for retirement together to optimize their savings, she said. The death of a spouse can also take a toll on income, she noted, especially if the spouse is still working at the time.

"You're suddenly faced with a situation where your income is oftentimes not what you have anticipated whereas your expenses often stay the same, or even higher," Haas said. "So if you have a house, if you have a mortgage, that doesn't change when somebody passes away."

Financial course correction: Retirees should consider working with a financial advisor to help plan for the possibility of such an event. According to the study, "27% of retirees and 30% of pre-retirees currently work with financial advisors, and 94% of them are confident in their ability to handle financial changes in retirement."

Retirees facing the death of a spouse or partner can also turn to government and social services programs to improve their financial security. But few do this currently. Only 16% of retirees have gone to these services. Of those who do, 88% say it improved their well-being in retirement.
