How Much Cash Should Retirees Keep?
Scott Hammel, CFP®, CRPC®
One of the most common questions we hear from people approaching retirement is:
“How much should we keep in cash?”
The answer changes once you retire.
During your working years, your paycheck continually replenishes your bank account. If the market falls 20%, you generally don't need to sell investments to pay next month's mortgage.
Retirement is different.
Your portfolio may now be responsible for helping create your paycheck.
That means cash isn't simply an emergency fund anymore.
It becomes part of your retirement income strategy.
A Good Starting Point: 1–2 Years of Portfolio Needs
As a general starting point, we often like retirees to have approximately one to two years of the amount they expect to need from their portfolio available in cash.
For example, imagine a retired couple spends $120,000 per year.
They receive:
- $60,000 from Social Security
- $20,000 from a pension
- $40,000 from their investment portfolio
From a purely mathematical perspective, we may focus primarily on protecting that $40,000 annual portfolio need.
In practice, however, keeping closer to one or two years of total spending can sometimes make the system simpler and provide additional comfort.
The difference isn't necessarily going to make or break a long-term retirement projection.
The larger objective is making sure enough liquidity exists that short-term market movements don't dictate long-term financial decisions.
Why Retirees Need More Cash Than Accumulators
Cash serves a different purpose in retirement.
While you're working, a market decline can actually be beneficial for money you're continuing to invest. Your contributions buy investments at lower prices.
Once you're withdrawing from a portfolio, the equation changes.
Imagine retiring with $2 million invested and immediately experiencing a significant bear market.
Your investments decline.
But your lifestyle doesn't disappear.
You still need money for:
- groceries
- utilities
- property taxes
- healthcare
- travel
- home repairs
- family expenses
If every dollar is invested, you may eventually be forced to sell assets after they've fallen substantially.
That's one reason cash reserves can be valuable.
They create time.
And time can be incredibly valuable during a market downturn.
A 20% Market Decline Doesn't Mean We Immediately Start Spending Cash
This is an important distinction.
Having a cash reserve doesn't mean that every time the market falls, we immediately sell nothing and live entirely from cash.
Retirement planning should be more nuanced than that.
We think of market declines in stages.
A relatively normal 5% market decline may require virtually no lifestyle adjustment.
At 10%, we may begin talking about delaying a major discretionary purchase.
If markets fall 15–20%, we may become more intentional about spending and evaluate whether cash reserves should begin supporting portfolio withdrawals.
During a severe bear market, cash reserves can become increasingly valuable because they may help reduce the need to sell investments at depressed prices.
The strategy isn't:
“The market is down. Panic and stop spending.”
It's:
“We planned for this. Here are the levers we can pull.”
That distinction can make a difficult market environment significantly easier to navigate.
Cash Helps Protect Against Sequence-of-Returns Risk
One of the biggest investment risks during the early years of retirement is something called sequence-of-returns risk.
The basic idea is straightforward.
Two retirees could earn similar average investment returns over retirement but experience very different outcomes depending on when those returns occur.
Poor returns during the first several years of retirement can be particularly damaging if you're simultaneously selling investments to fund your lifestyle.
That's because you're removing shares from the portfolio while their values are depressed, leaving fewer assets available to participate when markets eventually recover.
This is one reason retirement income planning isn't simply about selecting investments.
You also need a system for determining where the next paycheck comes from.
Cash Is a Warm Blanket
The more common problem we encounter isn't retirees having too little cash.
It's having too much.
And we understand why.
Cash feels safe.
You can see it.
It doesn't fall 20% when the stock market has a bad year.
For someone who spent 30 or 40 years building wealth, watching $300,000 sitting safely in a bank account can feel like a warm blanket.
There is nothing inherently wrong with that.
But safety has a cost.
The Risk of Holding Too Much Cash
Retirement can last 20, 30, or even 40 years.
Over that period, inflation becomes incredibly important.
Something that costs $100 today won't cost $100 forever.
Housing costs increase. Healthcare costs increase. Travel gets more expensive. Groceries get more expensive.
Cash may protect the nominal value of a dollar, but it doesn't necessarily protect what that dollar can buy.
That's why we don't think the objective should be:
“How can we make the retirement portfolio as safe as possible?”
Instead, it should be:
“How much short-term safety do we need while still giving the rest of the portfolio an opportunity to support decades of future spending?”
Those are very different questions.
Your Cash Reserve Should Work With the Rest of Your Retirement Accounts
This is where having multiple financial buckets becomes valuable.
A retiree might have:
Cash for near-term spending and emergencies.
A taxable brokerage account for intermediate needs and additional flexibility.
Traditional IRAs and 401(k)s providing long-term retirement assets and eventually Required Minimum Distributions.
Roth accounts providing another source of long-term, tax-free flexibility.
Instead of treating each account independently, they can work together.
That's a major part of how retirement income actually works.
The objective is not having the maximum amount of money in any single bucket.
It is having the right amount in each bucket for the job it needs to perform.
Your Cash Reserve Doesn't Have to Sit There Forever
Suppose markets perform well for several years.
Your portfolio grows.
You take distributions, rebalance investments, or receive an RMD that you don't otherwise need.
Some of those dollars can potentially replenish the cash reserve.
Conversely, if markets experience a significant downturn, the process can work in the opposite direction.
We may reach out and say:
“This is why we built the cash reserve. Let's start using some of it.”
That can be psychologically difficult.
Retirees sometimes see their bank balance declining and instinctively want to preserve it.
But the cash reserve was built for a reason.
Using it intentionally isn't the plan failing.
It is the plan working.
What About RMDs You Don't Need?
Required Minimum Distributions add another wrinkle.
Eventually, retirees with certain pre-tax retirement accounts must take distributions whether they need the money or not.
If those distributions aren't needed for lifestyle spending, they don't necessarily need to accumulate indefinitely in cash.
After accounting for taxes, excess distributions can potentially be reinvested in a taxable brokerage account.
We've written separately about what to do with excess RMDs.
For many of our clients, this becomes another way of maintaining the balance between:
cash → mid-term investments → long-term retirement assets.
There Is No Perfect Cash Number
Two retirees with identical portfolios may appropriately hold different amounts of cash.
Someone with substantial pension and Social Security income may need less from their investments.
Someone relying almost entirely on portfolio withdrawals may want more liquidity.
Other considerations include:
- spending needs
- guaranteed income
- portfolio size
- investment allocation
- upcoming major purchases
- healthcare needs
- comfort with market volatility
- tax strategy
That's why one to two years is a starting framework, not a rule.
The right cash reserve is the amount that supports both the financial plan and the person living it.
Don't Let Cash Become the Retirement Strategy
Cash can play an incredibly important role in retirement.
But cash itself isn't a retirement strategy.
Holding too little may leave you unnecessarily exposed to short-term market conditions.
Holding too much for decades can create its own risks through inflation and lost growth opportunities.
The objective is balance.
Enough cash to provide flexibility when markets become difficult.
Enough invested to give your assets an opportunity to support a retirement that could last decades.
And, most importantly, a process for knowing when to use each.
Final Thoughts
We don't build cash reserves because we know when the next bear market will happen.
We build them because we know eventually one will.
A thoughtful retirement plan should assume there will be periods when markets decline, headlines become uncomfortable, and spending decisions need to be adjusted.
That's not an emergency.
That's retirement planning.
When you have sufficient liquidity, diversified investments, and a clear retirement income strategy, you don't need to predict exactly what markets will do next.
You already have a plan for responding when they do it.
