Ten Lessons From Ten Safe Withdrawal Rate Case Studies

Last week, we published the Tenth Safe Withdrawal Rate Study! Amazing how time flies! I did about one case study every three weeks for the last 6 months! And I could even include another one if I were to count the one I did for the ChooseFI podcast back in 2017. In fact, the ChooseFI appearance (Episode 23R and Episode 26R) started the idea because our first volunteer reached out to me after he heard me on the podcast. Since then I’ve published 10 posts, worth almost 30,000 words that generated tons of clicks, feedback and encouragement:

  • “John Smith”: Seven-figure net worth, but not quite ready for FIRE yet. Big ERN would recommend a few more years in the workforce!
  • “Captain Ron”: Early retirement on a sailboat. How much can they withdraw from their $3m portfolio to stay afloat (pun intended) in retirement?
  • “Rene”: No need to worry about the recent layoff: You are more than ready for early retirement!
  • “Mrs. Greece”: More than ready to retire due to large portfolio size and moderate living expenses, especially if the husband keeps working!
  • “Mrs. Wish I Could Surf”: Alternative investments (real estate hard money loans). Keep the mortgage or pay it off? Either way, more than ready to retire!
  • “Mr. Corporate”: Geographic Arbitrage by moving to a low-cost European country. Roth Conversions and zero tax liability!
  • “Ms. Almost FI”: Your name is a misnomer. You are ready to retire now even when self-funding substantial long-term care expenses in the future!
  • “Mr. Corporate Refugee”: How to deal with a large portion of the net worth tied up in a house in a high-cost-of-living area?
  • “Mrs. Wanderlust”: Substantial supplemental cash flows due to buying an RV and then selling it later.
  • “Mr. and Mrs. Shirts”: Ready to retire this year, but should Mr. Shirts work for another nine months for some additional big payday?

But, alas, all good things have to come to an end! I have decided to take a break from the case studies, at least for now. I might revive the series again later but for next few weeks and months, I will pursue other topics! Thanks to all volunteers who submitted their data. And thanks to all other folks who didn’t get their case studies published. I’m not even sure I properly responded to everyone whose request was denied. I think I may have some inquiries from October last year that I haven’t responded to. If you submitted a request for a case study and haven’t heard from me back, sorry, I’m just a bit disorganized!

Sooooo, ten case studies: what have I learned from them? Plenty, because that’s the topic for today’s post…

Ask Big Ern: A Safe Withdrawal Rate Case Study for “Mr. and Mrs. Shirts”

Welcome to the 10th episode of our Case Study Series! Today’s case study is for Mr. and Mrs. Shirts. They run their own blog Stop Ironing Shirts and I encourage everyone to head over and check out their outstanding work. Mr. Shirts and his wife face a dilemma; they have already amassed a pretty impressive nest egg, probably large enough to retire later this year. But the temptation to work a little longer to cash in that next financial milestone around the corner (bonus, vesting date, etc.) is a pretty strong incentive to stay onboard for just a little bit longer. Otherwise known as the One More Year Syndrome. In fact, in the Shirt’s case, it’s only nine months (June 2018 vs. March 2019). So, what are the tradeoffs, what are the pros and cons of retiring in 2018 vs 2019? Let’s look at the details…

Ask Big Ern: A Safe Withdrawal Rate Case Study for “Mrs. Wanderlust”

It’s time for another Safe Withdrawal Rate case study today! Believe it or not, but this is already the ninth installment of the series! Check out the other case studies here. Today’s volunteer is Mrs. Wanderlust (not her real name), a frequent reader of the ERN blog. She and her husband plan to retire in 2018 (more or less voluntarily) and asked me to run their numbers. One challenge in pinning down a safe withdrawal rate: large additional cash flows because they plan to purchase of an RV and then sell it a few years later. They will also have different budgets during different phases in retirement. And not to forget, a four-legged family member that’s factored into their planning. So without further ado, let’s start calculating…

Ask Big Ern: A Safe Withdrawal Rate Case Study for “Mr. Corporate Refugee”

Welcome! It’s time for another Safe Withdrawal Rate case study! Please click here for the other seven installments. Today’s volunteer is “Mr. Corporate Refugee,” not his real name, obviously. But as the name suggests he is ready to pull the plug on the corporate grind. He and his wife did everything right to prepare for early retirement. Pay off the mortgage on their house (as recommended by yours truly) and accumulate a nice nest egg close to seven figures. The only problem: they reside in a high-cost-of-living area in California and more than half of their net worth is tied up in their primary residence. Even a portfolio as large as $1 million will likely not be sufficient to cover expenses in your current location. What to do now? I’ll propose two routes to early retirement. Move to a cheaper location, a “secret” low-income-tax paradise – more on that below, and be able to retire now. Or work for only four more years and retire in the current location. Let’s go through the math…

Ask Big Ern: A Safe Withdrawal Rate Case Study for “Ms. Almost FI”

Welcome to a new installment of our “Ask Big Ern” series with case studies on safe withdrawal calculations. This is already the seventh part, see here for the other parts of the series! Today’s volunteer is Ms. Almost FI and that’s not her real name, of course. She’s planning to retire early in 2019 and this causes a lot of anxiety: Does she have enough money? When should she take her pensions? What about long-term care insurance? All very valid questions, all impossible to answer without a careful customized analysis!Read More »

Ask Big Ern: A Safe Withdrawal Rate Case Study for “Mr. Corporate”

Welcome to the sixth installment of our “Ask Big Ern” series where I perform case studies in safe withdrawal calculations. See here for the other parts of the series.

Let’s make this Geographic Arbitrage Week because after Monday’s guest post on “Geographic Arbitrage,” I will now feature a case study with the same theme! Meet Mr. Corporate (not his real name) who reached out a while ago for advice on whether he’s ready to leave the corporate life. Just looking at his numbers I knew immediately that there is no way he and his wife can retire in their current location. But Mr. C found that moving to another country with lower living expenses will cut years off the time it takes to reach FIRE. And we’re talking about a country in Europe (he wouldn’t mention which one), with a high quality of life, nice climate, and a good healthcare system! Can he retire now? Let’s look at Mr. C.’s numbers…

Ask Big Ern: A Safe Withdrawal Rate Case Study for Mrs. “Wish I Could Surf”

Welcome to a new Case Study! This time, Mrs. “Wish I Could Surf” (not her real name) volunteered to open the doors to her finances. And every case study brings up something new to learn for yours truly. Today’s challenge: How would “alternative” investments factor into the Safe Withdrawal Rate exercise? Peer Street, Hard Money Lenders, Lendingclub, Prosper, etc. have gained a lot of popularity, especially in the FIRE crowd. When calculating safe withdrawal rates, I have only worked with stock/bond/cash portfolios because they are the asset classes with returns going back 100+ years. Doing the SWR exercise for a portfolio of Peer Street loans will require some “hacking” in my Safe Withdrawal Rate Google Sheet!

Further challenges come from the fact that Mrs. and Mr. Surf keep their finances separate (similar situation as in the Case Study for Rene) and Mr. Surf will still be working for a number of years, so we have to make some assumptions on how to assign the tax burden between Mr. and Mrs. Surf. Lots of work to do! So let’s get started and look at Mrs. Surf’s finances…

Ask Big Ern: A Safe Withdrawal Rate Case Study for “Rene”

Welcome! Today is the third installment of our Case Study Series. Please check out the other two posts here if you haven’t done so already:

Today’s volunteer “Rene” (not her real name) was laid off earlier in 2017 and is now living off her severance package. She wonders if she has enough of a nest egg to simply call it quits and retire in her late 40s. And many other questions: if/how/when to annuitize any of her assets and what accounts to draw down first? So many questions! As I pointed out in Part 17 of the Safe Withdrawal Series, a safe withdrawal rate calculation has to be a highly customized affair and that’s what we’ll do today again. Let’s see what the numbers say!

Ask Big Ern: A Safe Withdrawal Rate Case Study for “Captain Ron”

A month ago, I did a case study for a fellow FIRE planner (“John Smith”) and the reception was awesome. So why not do more of those? Without even asking for volunteers, I already got two more fellow FIRE planners who contacted me via email and shared their financial parameters. Today’s case study is for “Captain Ron” and, of course, Ron isn’t his real name, though he is indeed a Captain. Not the “Captain Ron” from the 1992 movie, but just a captain. More on that later!


Why are case studies so exciting? One of the most important lessons I learned from my Safe Withdrawal Rate research (jump to Part 1 of the series here) is that the safe withdrawal calculations are best performed on a one-by-one basis. As we pointed out in our post last week, a withdrawal rate strategy should respond to market factors like equity valuations and bond yields as well as personal factors like age, retirement horizon, and expectations about pension and Social Security benefits. Further complicating the whole calculation is also the fact that we all have different distributions of assets over taxable, tax-deferred and tax-exempt accounts. So, let’s take a closer look at Captain Ron’s situation…
