Americans looking for an affordable retirement shouldn't overlook overseas options, according to a new report.

International Living has compiled its 2021 Annual Global Retirement Index to find options for affordable and sometimes exotic destinations to retire. 

Relying on input from a global network of expats, International Living compared 25 countries across 10 metrics: housing; benefits; visas/residence; fitting in/entertainment; climate; healthcare governance; opportunity; and cost of living. 

Each of the countries ranked in the 2021 Annual Global Retirement Index is open to U.S. citizens during the ongoing Covid-19 pandemic, according to International Living.

Here, in ascending order, are International Living's top 10 best places to retire in 2021:

10. Vietnam

Once a French colonial possession, then a divided war-torn country, Vietnam is today a peaceful, friendly nation known for its beaches, rivers, Buddhist pagodas and bustling cities. The country scored a near perfect 99 for cost of living, as well as an 84 for healthcare, but earned a not-so-great score of 60 in benefits, visas/residence, and climate.
