The biggest retirement mistakes involve inadequate financial planning and poor lifestyle adjustments, primarily failing to budget for rising healthcare costs, underestimating life expectancy, and claiming Social Security too early. Other major errors include investing too conservatively, not adjusting spending, carrying high debt, and failing to plan for the emotional, non-financial aspects of life after work.
Roughly 7% to 9% of American households have $500,000 or more in retirement savings, though figures vary slightly by source, with data from late 2025 suggesting around 7.2% and older 2022 data indicating about 9%, showing it's a significant milestone achieved by less than one in ten families, despite higher averages driven by wealthy individuals.
The #1 regret of retirees is not saving enough money, with studies showing a large majority wish they had saved more and started earlier, leading to financial stress and limitations in their desired lifestyle. Other major regrets often center around a lack of planning for time, health, and experiences, such as working too long, putting off travel, or not planning for future healthcare costs, says financial experts and financial planning sources.
The $1,000 a month rule is a retirement guideline suggesting you need about $240,000 saved for every $1,000 per month in desired income, based on a 5% annual withdrawal rate (5% of $240k is $12k/year, or $1k/month). It's a simple way to set savings goals, but it doesn't account for inflation, taxes, or other income like Social Security, so it's best used as a starting point, not a complete plan.
Only a small percentage of Americans retire with $1 million or more in retirement savings, with figures from the Federal Reserve and Employee Benefit Research Institute (EBRI) showing around 3.2% of retirees hitting that mark, though some sources cite slightly lower numbers for all Americans (around 2.5%) or higher estimates for households nearing retirement (over 10% of older households have $1M+ net worth, not just retirement funds). The reality is most retirees have significantly less, with the median for ages 65-74 being around $200,000-$609,000 in retirement accounts.

People who had retired as late as possible are at a higher risk of suffering from a cognitive decline at any age. People who had retired as early as possible, on the other hand, show a decreasing risk of cognitive decline over time which mitigates the natural risk increase associated with ageing.
Eliminating a big debt early on could save you thousands of dollars in interest, freeing up money that could be added to your retirement savings and start gaining compound interest instead. Another thing to consider is that keeping up with large debts becomes more difficult in retirement.
As we have established, retiring on $500k is entirely feasible. With the addition of Social Security benefits, this becomes even more of a possibility. In retirement, Social Security benefits can provide an additional $2,000 per month, on average. You can start receiving Social Security benefits as early as 62.
