Are You Going to Be OK in Retirement? 1 Easy Calculation Can Provide the Answer
Running out of money in retirement is a common fear, but knowing you have enough cash on hand to get through a severe stock market downturn can help. It’s a figure I call your “Withdrawal War Chest,” and it’s simple to calculate.


The stock market goes through recurring cycles that look to us like the four seasons. Fear is rarely apparent in spring or summer and barely palpable even in the fall. However, the “winter” portion of a stock market cycle is typically the harbinger of emotion-filled missteps by many investors.
“Am I going to be living under a bridge?” This is a “winter” question that I have often been asked over the past four decades, especially by prospective clients without a plan, even those with millions of investable dollars. This is because much of the “top of mind” space in our brain is allocated to thinking about our basic needs, including food, clothing, shelter, health care, transportation and education. When the stock market goes down, the reptilian, self-preservation portion of people’s brains often takes over, and they worry first and foremost about funding their basic needs.
The next and most important “winter” question I get asked is, “Am I going to be OK?” This is often due to a misperception that “something seems to be different this time.” Different in a potentially very bad way, more unusual than anything we’ve ever seen, and as a result, I may not be able to live and enjoy anywhere near the quality of life I had planned throughout retirement.

At our firm, we have created a tool to provide clients with peace of mind showing them approximately how long they will be “OK.” I call this the “Withdrawal War Chest.” A war chest has historically been defined as a fund accumulated to finance a war, and recently, has expanded its meaning to a fund earmarked for a specific, challenging purpose. There are few financial endeavors more challenging than planning for retirement. Luckily, knowing your Withdrawal War Chest makes such planning much less stressful.
So how do you figure out your Withdrawal War Chest? Here’s our simple process:
- Add your total cash reserves AND total cash and bonds in your portfolios to get your War Chest.
- Divide your total War Chest by your monthly retirement withdrawal.
- That’s it.
This calculation provides an estimated time frame in which your War Chest (cash and bonds) alone could support your cash flow needs without withdrawing or selling a single penny from equities (stocks). To show you what that calculation could look like, let’s look at a hypothetical couple — John and Jane — who have a nice cash cushion saved up.
While the War Chest calculation is a simple one, its impact is tremendous. Your monthly Withdrawal War Chest is not only protection, but most importantly, peace of mind. Take John and Jane from our example above. They have 14 years and 3 months’ worth of withdrawals that is completely independent of the stock market. They don’t have to worry about it bouncing up, down or sideways. It’s just a quick snapshot, but it’s one that offers people confidence, because if the stock market goes through an extended “winter,” people are sure they can withstand it by not being forced to sell low.
The majority of people who liquidate most or all of their stocks while going through stock market downturns don’t have a plan and give in to fear. These types of emotional decisions often result in financial losses that are never recovered. This is not something you want to say when reflecting back on your life savings. While there is no magic wand to wave to take the emotions out of a decision, having a plan in place and knowing your Withdrawal War Chest can make those winter periods much less stressful.
Our typical retirement monthly Withdrawal War Chest has 10+ years of withdrawals. That being said, each individual household and family has their own unique needs. However, if you have a plan and know your Withdrawal War Chest, you can take a lot of anxiety out of investing and planning throughout retirement.
