The retirement income gap is one of the biggest challenges many Americans face as they prepare for life after work. Many Americans approach retirement with a simple assumption: save consistently, rely on Social Security and a 401(k), and everything will work out. But the reality is more complex. Retirement planning today is less about hitting a savings number and more about ensuring your income can sustain your lifestyle—no matter how long you live.
For many households, this begins with one important question:
“Will your income actually cover your expenses?“
Recent estimates suggest retirees spend around $5,300 per month. According to the Bureau of Labor Statistics, average annual expenditures for households age 65 and older typically range between $50,000 and $70,000 depending on lifestyle and location. While that may offer a baseline, it rarely reflects real-life spending habits.
Most people don’t dramatically cut expenses in retirement. In fact, they often spend more—traveling, visiting family, or pursuing long-delayed goals. The better approach is to calculate your own lifestyle costs based on current spending, then adjust for what you plan to do more (or less) of in retirement.
At Aul Financial Group, LLC, this personalized evaluation is often the first step in building a realistic retirement strategy.
Once you’ve outlined your expenses, the next step is comparing them to your guaranteed income sources, typically Social Security and pensions.
If your lifestyle costs exceed these income streams, you’ve created a “retirement income gap.”
For example, a retiree with a $1,800 monthly shortfall would need to generate that income from investments or savings. This gap is more common than many expect, especially as fewer workers have traditional pensions.
Identifying this gap early allows you to plan intentionally instead of reacting later.
The 4% rule has long been a go-to guideline for withdrawing retirement savings. It suggests you can withdraw 4% of your portfolio annually with a reasonable chance of not running out of money.
The rule originated from research by financial planner William Bengen and was later supported by studies such as the Trinity Study, which examined sustainable withdrawal rates over time.
However, longer life expectancies, market volatility, and inflation have introduced new risks. While the rule may still work in some scenarios, it no longer provides the same level of confidence across all retirement timelines.
That’s why many advisors now treat it as a starting point—not a complete strategy.
The 401(k) remains a valuable savings tool, but it wasn’t originally designed to serve as a standalone retirement solution.
Over time, several challenges have emerged:
Additionally, recent changes to inheritance rules mean many beneficiaries must withdraw inherited retirement funds within a relatively short timeframe, potentially increasing their tax liability.
At Aul Financial Group, LLC, advisors often encourage clients to evaluate their 401(k) as part of a larger income plan rather than relying on it exclusively.
One way to address the income gap is by converting a portion of your assets into a predictable income stream. This approach, sometimes referred to as a “personal pension,” focuses on generating consistent income you cannot outlive.
By allocating part of your savings into products designed to provide guaranteed income, retirees can cover essential expenses with more certainty. That, in turn, allows remaining assets to support discretionary spending, inflation adjustments, or legacy planning.
This type of structure helps answer one of the biggest questions retirees face:
“Is my lifestyle secure?“
A successful retirement plan is not just about accumulation, distribution, stability, and flexibility.
