In the years after retirement, many people find they no longer have the same financial comfort as they did in the early days of retirement. No longer do they have the same means to enjoy the life they once did. Often, people find themselves forced to use their cash cushion to survive. But, using a cash cushion for survival only works for a short time because you will eventually need to live on the income from that cushion. So, is it better to use your cash cushion for retirement purposes or to keep it as a cash cushion?

We’ve all heard the idea of saving up a “cash cushion” so that in case of an emergency, you could be prepared. But what does that actually mean? And is it even a realistic thing to do?

In recent years, many people are taking the first step towards getting ready for retirement by opening a cash cushion. While the benefits of a cash cushion are undeniable, so are some of the dangers. A common misconception is that with a cash cushion you are saving money…. Read more about what to do with cash in retirement and let us know what you think.

Should you use a cash cushion in retirement?

You withdraw from your primary month after month when you retire using a safe withdrawal rate. The major danger is that you will run out of money before you reach retirement age.

If you retire soon before a huge stock market meltdown, this is the most likely scenario. A poor run of performance poses a significant danger to your retirement. Lessen the safe withdrawal rate you’re utilizing to reduce the danger. However, this means you’ll need to save substantially more money. You can also find yourself with a large sum of money at the conclusion of your retirement.

Another option that many individuals consider is to keep more cash on hand to protect themselves against this risk. This is just what we will discover today!

I’ve created a couple scenarios in which so-called cash cushions are used in retirement. We’ll have to see if that makes sense.

The issue at hand

The most significant risk in retirement is a poor return sequence. If you begin retirement near a significant stock market crash, your wealth will suffer greatly in the first few years. As a result, your effective withdrawal rate will be substantially higher than you anticipated. Furthermore, you face the chance of running out of money considerably sooner than you intended!

The main way to mitigate this danger is to be more cautious with your withdrawal pace. It is possible to make a substantial difference by lowering your withdrawal rate. However, lowering your withdrawal rate will result in a large rise in the amount of money you’ll need to save before retiring. As a result, you will have to labor longer.

Many people feel that having a huge cash buffer before retiring can improve your portfolio’s success rate greatly. They also feel that by doing so, they will be able to retire earlier.

Let’s take a look at how a cash cushion functions in retirement.


To find, I am going to run simulations of the Trinity Study. For this, I am going to use data from the S&P 500 index for the stocks. And I will use U.S. Treasury bonds for bonds.

These simulations are done with my own tool. Check out my Updated Trinity Study article for more information on the tool and data. For more simulations, I’ve added cash support to my tool.

The success rate is the simulation’s output. The term “success” refers to not running out of money before the simulation ends. A simulation that ends with 1 CHF is considered a success. The success rate, on the other hand, is the percentage of successful simulations in a set of simulations.

More than 2 million possibilities were simulated for this article!

Withdrawing from stocks should be postponed.

The most basic concept of a liquidity buffer is to postpone stock withdrawals. It means that instead of withdrawing from the portfolio, you are withdrawing from the cash for the first M months.

For example, if you spend $3000 every month, you could save up to $18,000 (M=6) and only take money out during the first six months. That manner, your portfolio would expand over the first six months of retirement, giving it a better chance of long-term success.

This is a simple illustration of a cash cushion. However, it is intriguing to begin with a tiny project.

Let’s start with a 30 year retirement period and a 4% withdrawal rate. I’ll simulate increasing the financial buffer from 0 months (no cash cushion) to 60 months.

Simple Cash Cushion - 30 years - 1871 - 2020 - 4% WR Simple Cash Cushion – 30 year horizon – 1871 – 2020 – 4% WR

On this graph, we can see a few things. First and foremost, using some cash improves the success rate of the various scenarios. It can even boost a 25 percent stock portfolio’s chances of success from less than 80% to 100%. However, you’d need to save up for more than 50 months’ worth of bills. This has a big impact on how long it takes you to achieve financial freedom and retire.

I’ll remove it from the graph to make it more readable because the possibilities of retiring with a 100% bond holdings are quite slim.

Simple Cash Cushion - 30 years - 1871 - 2020 - 4% WR 2 Simple Cash Cushion – 30 year horizon – 1871 – 2020 – 4% WR

We can see how having a cash cushion makes the 4% withdrawal much easier. Even a 50 percent equity portfolio, on the other hand, has a greater than 95 percent chance of success. We need to examine what occurs after 40 years of retirement to see if it makes a significant difference.

Simple Cash Cushion - 40 years - 1871 - 2020 - 4% WR Simple Cash Cushion – 4 percent WR – 40 years – 1871 – 2020

The 50 percent equity portfolio will have to be eliminated for a 40-year retirement.

Simple Cash Cushion - 40 years - 1871 - 2020 - 4% WR Simple Cash Cushion – 4 percent WR – 40 years – 1871 – 2020

Surprisingly, even if you have a monetary buffer for 40 years, it can have a big impact on your chances of success. Adding 30 months of cash to a 75 percent or 100 percent stock portfolio, for example, would increase the chances by approximately 100%. Some people who want to be more conservative might benefit from this.

Finally, consider a retirement of 50 years.

Simple Cash Cushion - 50 years - 1871 - 2020 - 4% WR Simple Cash Cushion – 4 percent WR – 50 years – 1871 – 2020

This time, we can see that a 4 percent withdrawal rate and a 75 percent or 100 percent stock portfolio would require at least 40 months of cash buffer to achieve a 100 percent likelihood of success.

However, adding a 12-month cash cushion to an aggressive portfolio would increase your chances of a successful retirement by a few percentage points. During that time, your portfolio would have grown to the point where you’d have a better chance of succeeding.

A wise cash reserve

I felt we could have a smarter cash buffer approach before running these simulations and authoring this blog. Using the financial cushion during the first M months, I was thinking, was not the best idea.

The cash buffer would be used based on the current effective withdrawal rate, which was my concept. We would withdraw from cash if this rate was higher than the predicted withdrawal rate; otherwise, we would withdraw from the portfolio. However, it turns out that this is not a big improvement over withdrawing cash whenever possible.

Here are the results of the smart cash cushion over the last 50 years:

Smart Cash Cushion - 50 years - 1871 - 2020 - 4% WR Smart Cash Cushion – 4 percent WR – 50 years – 1871 – 2020

It does not appear to be significantly different from the previous results. I’ve put both on the same graph for a better look:

Smart vs Simple Cash Cushion - 50 years - 1871 - 2020 - 4% WR Smart Cash Cushion vs. Simple Cash Cushion – 50 years – 1871 – 2020 – 4% WR

As you can see, there are very few differences between the two tactics. The tiny technique is marginally better for a short period of time. The simple technique is marginally better over a long period of time. However, given these distinctions, the basic technique is clearly superior because it is both simpler and more effective!

Another option, which I have not tried but which should produce comparable outcomes, is to withdraw exclusively from cash when we are in a long period of decline (a bear market). Since your effective withdrawal rate is substantially larger in a downturn, this should be quite similar. The difference is that during a bear market, we would use up the full cash buffer instead of only a portion of it at the start.

Overall, it appears that postponing withdrawals for the first M months while maintaining a financial cushion is the optimal plan. A more intelligent strategy isn’t required.

When compared to a lower withdrawal rate,

Having some cash on hand in addition to your portfolio indicates you have a larger total net worth. It also means that your effective withdrawal rate based on your overall net worth will be lower than your portfolio’s planned withdrawal rate.

In fact, putting some money aside for a few months can be linked to a different withdrawal rate. With a withdrawal rate of 4%, for example:

  • A 3.84 percent withdrawal rate is equivalent to 12 months of cash cushion.
  • With a cash buffer of 24 months, you’re looking at a 3.70 percent withdrawal rate.
  • A 3.57 percent withdrawal rate is equivalent to 36 months of cash cushion.
  • With a 48-month cash buffer, you’re looking at a 3.44 percent withdrawal rate.
  • With a 60-month cash buffer, you’re looking at a 3.33 percent withdrawal rate.

So, what’s the difference between a financial cushion and limiting your withdrawal rate? Let’s have a look!

Let’s start with 30 years of retirement once more. We’ll compare creating a several-month cash cushion (CC) against boosting your portfolio by the same amount (WR). The WR is reduced when the portfolio is increased.

Cash Cushion vs Lower WR - 30 years - 1871 - 2020 - 4% WR Lower WR vs. Cash Cushion – 30 years – 1871 – 2020 – 4% WR

As expected, there isn’t much of a difference between these two approaches. Nonetheless, there are two noteworthy things to notice:

  • A lower WR is nearly always preferable to having a cash cushion when you have a modest stock allocation.
  • A cash cushion is marginally better than a lower withdrawal rate for a high stock allocation.

Let’s explore if these conclusions apply to a 40-year retirement.

Cash Cushion vs Lower WR - 40 years - 1871 - 2020 - 4% WR Lower WR vs. Cash Cushion – 40 years – 1871 – 2020 – 4% WR

Surprisingly, the same threads may be seen starting with 20 months of capital accumulation. Before that, there isn’t much of a difference. For a portfolio with 50% in equities, a lower withdrawal rate is slightly better after 20 months. The cash cushion, on the other hand, is slightly better for a portfolio that is entirely made up of equities. Both strategies work well with a portfolio that contains 75% equities.

Finally, consider what happens after you’ve been retired for 50 years.

Cash Cushion vs Lower WR - 50 years - 1871 - 2020 - 4% WR Lower WR vs. Cash Cushion – 50 years – 1871 – 2020 – 4% WR

There isn’t much of a difference between the various strategies. However, we can see a pattern:

  • A lower WR on a portfolio with 50% stocks has a better likelihood of success.
  • There is basically no difference in a portfolio with 75% stocks.
  • A cash cushion is slightly better than a smaller WR in a portfolio with 100% equities, but only for more than 20 months in a cash cushion.

In the end, both tactics are viable. However, accumulating money in a portfolio is often easier than accumulating cash. The money you put into your portfolio will grow, however the money you keep in cash will not.


In general, having a monetary cushion in retirement offers no major benefits. Having a small monetary cushion to use as a stopgap can improve your chances of succeeding. Overall, though, it performs approximately as well as putting the same amount of money into your portfolio.

Having a little extra income is a lot like having a little extra money in your portfolio. As a result, there will be fewer withdrawals and a greater probability of success.

So, if you want to improve your odds of success, I’d suggest delaying retirement or lowering your withdrawal rate. This is more logical.
