The Biggest Risk of All

In the personal finance community we often talk about risks. The risk of running out of money in retirement; the risk of picking the wrong investment or getting the timing wrong; sequence of return risk; the risk of losing our job during the accumulation phase; leverage risk – you name it.

The perceived level of danger that comes with these risks often leads to fear. This fear in turn leads to phenomena like the famous ‘one-more-year syndrome’.

We try everything we can to minimise these risks, calm our fears and be “safe”. However, we often ignore a risk that we should all pay a lot more attention to: the biggest risk of all.

We Are All Terrible At Managing Risk

As humans, we are terrible risk managers, especially when it comes to risks we can’t easily quantify and that have fears and emotions attached to them. We overestimate the impact of some risks and underestimate that of others.

The truth is that no decision we’ll ever take is risk-free. We just have to pick and choose which risks we are willing to take.

Investing comes with risk. We all know that. However, in the FI community, we acknowledge that not investing is even more dangerous long term, so we are happy to accept the risk that comes with investing.

But what about the risks we can’t display in a pretty spreadsheet? Like failing to make positive changes in our life when we get the chance? What is the risk of holding on to a job we don’t like “just for another year or two” once we don’t need it anymore to be financially secure? This is where things get complicated.

These kinds of decisions also come with risk; a lot of risk actually.

When we delay happiness and decide to stick it out just one more year to “be safe” or “build some more buffers”, even when we know we have enough, we unwittingly prioritise the risk of running out of money over another risk: running out of time. And that, my friends, is the biggest risk of all.

Once we have reached a level of financial independence that allows us to start making changes in our lives – like working less, semi-retiring or taking a career break for instance – the fear gets real for many of us. We suddenly think our plan is too risky. We come up with a million reasons why now is not the time or why we just need a little bit more money before we can take the leap. We are worried we don’t have enough.

All the while, we tend to ignore the biggest risk of all – running out of time – hiding in plain sight.

Hiding In Plain Sight

In a recent article, we used the Rich, Broke or Dead Calculator to show the effect of flexibility and some active income on our success chances in retirement. The calculator produces pretty graphs like this:

Today, I’ll use the calculator to illustrate the very real risk of running out of time long before we get to use all the wealth we’ve accumulated.

For the scenario we’ll discuss in this article I used an allocation of 95% stocks and 5% cash, a retirement age of 40 and a retirement “end date” of age 100. I picked the mortality table for females with average health. I used the classic 4% rule without any flex or additional income. This is your run-of-the-mill FIRE scenario. Note: I discussed the calculator and how it works in more detail here.

The green area shows various levels of “enough” and “more than enough” – i.e. we won’t run out of money. The small red area is what everyone is so worried about – running out of money in retirement. In the scenario in the chart above, we have a 10% chance of running out of money sometime before age 100.

To simplify things, I’ve removed the various shades of “enough” (the green areas of the chart). The chart now only shows one shade of green for “success” (meaning we don’t run out of money in retirement):

The FI community goes to extreme lengths to avoid ending up in the little red area of the chart. We overanalyse, overthink, over-save and overwork. As a result, we often get stuck in what I call the “red zone” of the Financial Independence Spectrum.

The risk of running out of time (aka mortality risk) is displayed as the grey area. In my opinion, this is the area we should actually worry about. In the scenario I used, the risk of dying keeps creeping up year after year, and the risk of running out of money doesn’t even come into play until about 25 years after the retirement date.

This means that up until age 65, it is 100% more likely that we will die than that we’ll run out of money in any given year. And after that, the mortality risk just keeps going up and up and up. The likelihood of running out of time never overtakes the likelihood of running out of money. And at some point, the likelihood that we are dead is higher than that we are alive, whether we are broke or not.

Our risk of dying is never 0%, even in our 30s, 40s and 50s, when most aspiring early retirees believe they are “safe”. Think about that.

The Numbers Don’t Lie

Let’s have a closer look at the chart.

When we retire at age 40, our risk of being broke is, of course, 0%, and our risk of being dead is 0.1%. So far, so good.

Age 40

At age 50, there is still a 0% chance we’ll be broke, but a 2.3% chance we’ll be dead – 23 out of 1000 women of similar health are dead by this age. Also, note that there is a whopping 97.7% chance that we’ll be alive and kicking with plenty of money.

Age 50

Fast forward to age 60. Still a 0% chance of being broke, but a 7% chance of being dead:

Age 60

Now let’s look at age 66. This is the first time there is a real chance we might be broke – a 1% chance. Which is still nothing compared to the 11.8% chance we’ll be dead.

Age 66

By age 75, our chances of success (defined as alive and not broke) have decreased to 70.7%. There is a 4.2% chance we’ll be broke and a 25.1% chance we’ll be dead.

Age 75

At age 85, it’s more likely than not that we’ll be dead (a 54.4% chance), but there is still only a small risk we’ll be broke (4.6%).

Age 85

And finally, at age 95, we’ll most likely be dead (a 90.5% chance), and it’s improbable I’ll be broke (1% chance).

Age 95

I repeated this little experiment with various withdrawal and flex rate assumptions, and the results were very similar. We would have to withdraw over 5% per year without any flexibility to our spending and post-retirement income before the chances of being broke become greater than being dead at any point along the journey. And even then, this would only be the case for a few years of our retirement.


I hope this article got you thinking about the risk-reward trade-offs we all make on the journey to FI, whether we want to or not. There are no 100% safe options. Life is full of uncertainties.

I am definitely not trying to say that we should give up our pursuit of financial independence and only live in the here and now. However, I think it is important that we regularly check in with ourselves and ensure we are not delaying living our best lives unnecessarily.

Remember, tomorrow is not guaranteed for any of us. Make sure you are intentional when you choose which risks you are willing to take.

How do you balance the risk of running out of money with the risk of running out of time?

  1. Hi, related to the chance of running out of money by a certain age is suddenly being divorced and having to hand over half your savings to your ex – and then having to start living and saving again except now with less time to achieve your own personal FIRE moment. Would you like to do an article on how to recover from divorce and still achieve Financial Independance?

    • Depends on how early you pull the pin on the marriage. I did it when our kids were 5, 3, 2 and 11 months old. 25 years later I’m FI, but it took well over a decade to get back to feeling even vaguely financially stable.
      Weird phrasing you used though… “Hand over half YOUR savings to your ex”… surely the savings are joint, so each person is just getting their fair share?

      Anyway, LOVED this post. I’ve also played around with this calculator, but I never thought to view it the same way you have, Mrs Flamingo. I retired in 2020, but started picking up casual teaching work this year. oof. It has NOT been a very happy year, so this post resonates with me!

    • I’m not sure I’m the right person to comment on the issues that come with divorce since I have not been in a situation like this before. But generally I always thought of it as a math problem more than anything. Wouldn’t the assets be split evenly (taking into account if one spouse worked less to raise kids etc.)?

  2. Time is the most precious asset any of us have, it’s a one chance option to use it wisely or lose it, the older I get (I’m 41) the more I realise how precious time is, no number compares. Live today, when you can, tomorrow is promised to no one.

  3. Perfect timing as per usual. I some how stumbled on a Superannuation series launched by 730 (ABC show) and of course most of the people featured were not financially ready to retire, it got me worried all over again. My brain was already going to the ‘just in case, one or two more years’ I still have quite a bit of time before i get to this time, but its great to work on these thoughts before i get to that time. I am living life and enjoying holidays whilst building but yet to find where I belong outside of work, something i am working on now and phasing it in. Thank you for all you do and sharing how to pivot our focus to think about the things that really matter.

    • Yes, it’s so easy to get scared (especially by the news and shows like 7.30!) and go into defence mode. Remember, it’s all a process and no one retires and knows 100% what they want to do for the rest of their life. It takes time and changes many times along the way. All the best!

  4. Ooooh this is such a good post! I think we need to focus on this a lot more – a 25% chance I’m dead by 75 – whoa! I definitely get obsessed with the ‘what if I run out of money’ red zone and should focus much more on the ‘dead’ grey zone. When you state the stats like you did, I’d much rather run the risk of running out of money at 75 but have retired early enough to enjoy that retirement – rather than delay retirement and die with money in the bank.

  5. Nice. Thought-provoking indeed. Regarding the calculator, wouldn’t we need to estimate a yearly passive income and estimate an average tax rate? Or is that accounted for somehow?

  6. We need more discussions like this in the FIRE community! It’s too true we get sucked into the over analyzing, hyper focus on the red zone and seem to shuffle off the grey zone topic. Great read and I’ll definitely be linking to it in an upcoming post!
