Typical measures of retirement readiness include dimensions related to one’s accumulation or projected accumulation of retirement assets. However, I would argue that this measure needs to be factored by financial wellness. Our research has shown consistently that two people with the same income and financial resources can have very different results in their quality of lifestyle.
The difference between these two people is their financial wellness. The financially "well" person can stretch money far more than the financially "unwell" person, particularly in retirement. Getting an accurate and realistic assessment of retirement readiness in the United States is going to require an assessment of financial wellness.
