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

earlyretirementnow.com

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…

Mr. Corporate’s situation

I’m 39 years old and my wife will turn 40 next month. I make about $250K plus another ~$50-75K in RSU’s granted each year that vest over a 4 year period. My wife does volunteer work full time and does not collect a paycheck, but frankly, I feel like she works more than I do – and is a lot more satisfied! No kids. We are looking to retire early (probably April 2018). I’m not sure if it’s a full retirement for me, or if I’ll do some projects on the side, but I definitely want to get out of the corporate world. We currently live in high cost of living and are looking to sell our house and move to Europe to a low cost of living area.

Assets:

  • 401K: $350K (invested in S&P 500 Index Funds).
  • Vanguard: $117K (90% VFIAX and 10% VBTLX, although I’m thinking of moving all to VFIAX). (95% of this is cost basis, only 5% capital gains).
  • RSU’s [Restricted Stock Units]: I currently have $108K vested with another $30K set to vest before I quit. [ERN confirmed: Net of taxes!]
  • House: I expect it to sell it in 2018 and get $600k net after paying off the mortgage.
  • Savings: $50K in a credit union savings account

Wow, that’s a nice nest egg! It’s probably not enough to retire in your current HCOL area but this goes a long way in a more affordable country!

Social Security: If we never work again, our payments at 67 are estimated to be $2,198 (me) and $688 (wife)

Nice! And keep in mind that your wife, at least under the current rules, has the option of receiving 1/2 of your benefits, which would be higher than her own. Of course, given your age, I’d still like to apply a 20% haircut to your benefits in light of potential benefit cuts in the future. But $31,651 in benefits (=$2,198×1.5x12x0.8) in today’s dollars (!) is still a very impressive sum.

Retirement Life and Expenses: When we move to Europe I expect our yearly living expenses to be ~$35K / year. $25K for regular living expenses, $7-8K for travel, and some wiggle room. We have a pretty solidified plan for spending our time doing volunteer work in Europe which we are really excited about, learning the language, and immersing ourselves in the local culture. We have the means to become permanent residents there so the plan is to stay there if we can. Since we don’t have any children, we don’t really need to leave any money to anyone, so that’s not a concern. We will move our US home base to a state where we will have better tax treatment for things like capital gains, etc.

This is the beauty of geographic arbitrage! For $35k per year, you can probably rent a 1 bedroom apartment in some of the notorious HCOL areas in the U.S.! But $35k a year affords you a pretty nice lifestyle, including housing and healthcare.

Questions

  • Will we have enough for retirement or will I have to supplement with some part-time/project work?
  • How should I draw down my funds?
  • Should I think about doing a Roth IRA conversion ladder?
  • I’ve read every single one of your blogs and love them. One question I had was how to easily calculate CAPE and then adjust monthly or yearly withdrawals based on that? I may have missed it.

All excellent questions. We’ll get to those later. First, let me make clear that there are a few aspects of the move to Europe that I can’t confidently comment on:

  1. Immigration: I’m not an immigration lawyer. I assume you and your wife have dotted all the i’s and crossed all the t’s on that front.
  2. Taxation: I’m not a tax expert, certainly not on taxes abroad. For the calculations here, I assume that you stay a U.S. tax resident and don’t have to pay taxes in your new domicile. I hear that many European countries have much higher taxes on capital gains and dividends than the U.S.! Before you move you probably want to talk with a tax attorney (potentially one in the U.S. and one in your new home country) to confirm.
  3. Health insurance: In our email exchanges, we confirmed that you will pay for health insurance out of pocket in your new country (already included in the $35k budget). I would make sure that you can also avoid the mandatory Obamacare premiums in the U.S. Of course since you’ll be able to keep your taxable income quite low (more on that below), O-care wouldn’t cost you much so maybe it’s not a bad option to have in case you plan extended visits back in the U.S.

The gorilla in the room: Exchange Rate Risk

Before we get started with the SWR calculations, let’s point out one of the drawbacks of international geographic arbitrage: You have a portfolio denominated in dollars but expenses denominated in Euros. What can possibly go wrong? The Euro could appreciate vis-a-vis the USD! Then you’d have to cut your expenditures and/or increase your withdrawals from your USD denominated portfolio. Currency fluctuations can be brutal! And they are notoriously hard (impossible?) to predict. The spot exchange rate is about $1.18 per Euro at the time of writing this. But since 1999, the exchange rate ranged from $0.82 to over $1.60. If the EURUSD exchange rate were to go back to its peak from around 10 years ago you’d have to increase your withdrawals by about 36% to around $47,500 per year, just to maintain your spending level.

The EURUSD rate has been all over the map! If the Euro were to become stronger your retirement expenses measured in USD go up!

How do you alleviate exchange rate risk? I can think of at least a few possible routes:

  1. A currency hedge through derivatives. Sounds complicated, but it’s actually pretty simple. You’d need a brokerage account that can trade currency futures. I’m not sure you want to go that route because it raises a few issues. For example, do you want to hedge the entire portfolio or of only a portion? The profits from hedging could eat up your 0% federal tax bracket and invalidate your Roth conversion ladder. Or you might just not be comfortable dabbling in derivatives and trading EURUSD futures on margin.
  2. Buy Euro-denominated equities. Not the entire portfolio but a significant portion. For example, an ETF like the Ishares Ticker IEUR (0.10% annual expense ratio) or Vanguard’s VEUSX (also 0.10% expense ratio),  while traded in the U.S. and denominated in USD, the underlying securities are European stocks. Careful, though, because this also includes Swiss and U.K. stocks that are not traded in Euros (there is a Eurozone-only fund, Ticker EZU, but that has an almost prohibitively high expense ratio: 0.48%!). Even with the UK & Swiss stocks, you should get a decent degree of currency hedging and maybe some diversification benefit as well. Though, keep in mind my recent article on the limits of international diversification. Whatever international fund(s) you buy, make sure they are not currency-hedged! For example, the iShares Ticker HEFA (Currency Hedged MSCI EAFE) would be hedged back to USD, which is something you don’t want. You want the foreign exchange rate exposure!
  3. Ignore the currency risk and if the Euro appreciates simply increase the withdrawals up to a point. Maybe generate some supplemental income. If you see that you deplete your portfolio too fast, simply do a reverse geographic arbitrage and move back to the U.S., to a low-cost area. As we will see below, you do have quite a bit of a cushion and could probably withdraw closer to $48,000 and still be safe.
  4. Another reason to not stress out too much about FX risk; in the event of another global market meltdown, the USD will likely appreciate (the USD is a safe haven currency), so not hedging the currency exposure could actually provide a hedge against Sequence Risk.  But, of course, there is no guarantee that the next crisis looks like the last one.

The safe withdrawal rate calculation

Starting with your $1,255,000 portfolio and taking into account your Social Security benefits, let’s punch that into the Google Sheet and see how different historical retirement starting dates would have performed. I am using an allocation of 80%/17%/3% Stock/Bond/Short-term and the roughly 0.2% monthly income from Social Security (in % of today’s portfolio) starting in year 27 (month 325):

Link to Google Sheet

The results look really good: Even with today’s elevated CAPE ratio and Social Security pretty far in the future, you can probably go up to around 3.9%. That’s almost $49k per year. The $35k per year would be only 2.8% of today’s portfolio, much lower than all the failsafe withdrawal rates. But again, due to exchange rate risk, you probably want this safety cushion.

Main results from the Google Sheet. A 3.9% SWR seems feasible!

Cash flows until age 70

I always like to simulate the cash flows and portfolio holdings up to age 70 just to make sure there are no obvious problems with a) running out of money in taxable accounts before age 59.5 and b) over-accumulating money in tax-deferred accounts that would trigger a nasty tax bill at age 70 when required minimum distributions kick in.

You are in an extremely fortunate situation in that you’ll have plenty of assets in your taxable accounts to fund your life until you turn 59.5. And they are almost exclusively cost basis and almost no capital gains!

Assumptions:

Account balances over time, part 1. All mounts are nominal, except for the real portfolio value column.
Account balances over time, part 2. All values are nominal!

Results:

Summary so far: Both the SWR historical simulations and the cash flow analysis over time look really good!

A dynamic Withdrawal Rate System

Back to your question:

I’ve read every single one of your blogs and love them. One question I had was how to easily calculate CAPE and then adjust monthly or yearly withdrawals based on that? I may have missed it.

I think that’s a great question! We sometimes forget that withdrawals are not something you want to set and forget. You should constantly revisit the withdrawal amounts and check if they are still sustainable. A CAPE-based rule I personally liked a lot is to use the one recommended in the post from a few weeks ago (SWR series Part 18):

SWR = 1.75% + 0.5 x 1/CAPE

Maybe if you’re a bit more conservative with your withdrawals, take it down to

SWR = 1.50% + 0.5 x 1/CAPE

With today’s CAPE of around 30, the safe withdrawal rate would be 1.50% + 0.5x(1/CAPE)=3.167%. (Side note: for some of the European indexes the CAPE is a bit lower so your overall portfolio CAPE might be lower which will increase your SWR!) Multiply that 3.167% rate by your net worth ($1,255,000) and your withdrawal amount comes out as $39,742 p.a. or $3,312 per month. Of course, this calculation is still too conservative because a) you’d ignore your Social Security benefits and b) you ignore your willingness to exhaust your capital in the long-term (the CAPE rule was calibrated to preserve capital indefinitely!).

Adjusting for Social Security

This calculation was the topic of Part 17 of the SWR Series. Given that you expect around 2.5% of today’s portfolio in future Social Security benefits (with COLA!), how much of an additional withdrawal amount would that imply? According to the calculations from that post, with an 80/20 portfolio and a horizon of 60 years, you can increase today’s SWR by at between 0.262% (25Y horizon) and 0.205% (30Y horizon) per 1% of future COLA benefits. And that’s the worst case scenario! Taking the weighted average to get the value for 27 years, we get 0.239%. Multiply that by 2.5 because you’re expecting 2.5% in benefits relative to today’s portfolio and we get an additional 0.6% in the SWR. Add that to the baseline CAPE-based SWR and we are now at 3.767% SWR. Cool, we increased the initial withdrawal amount to over $47k!

The impact of cash flows with Cost of Living Adjustments on the SWR as a function of 1) start date (rows), 2) S/B portfolio allocation (columns) and 3) Retirement horizon (columns). The top/middle/lower panels are for the minimum/median/maximum values over the 1871-2015 simulation windows. From SWR Study Part 17.

Adjusting for capital depletion

Analogously to the Boglehead VPW calculations, we can determine the withdrawal rate that would amortize (deplete) your initial portfolio over time. Here’s how to do that in MS-Excel. It’s roughly the same as a mortgage payment calculation:

=PMT(0.03767/12,720,-1,0,1)*12

Calculating this in Excel, I get an SWR of 0.04194, i.e., 4.194% annualized. That’s even a little bit higher than the SWR calculated with the historical simulations. Makes sense, because your withdrawal amounts will decline in case of Sequence Risk and bad returns early on. But even a drop of 35% in withdrawals would still keep you above the $35,000 target you set.

Adjusting the SWR when going forward

Of course, the CAPE will change every year and the number of years before reaching Social Security will decline. Same with the capital accumulation adjustment. So, you should recalculate this number every once in a while to see if you’re still on track with your withdrawals! I get my CAPE numbers from Robert Shiller (link here and click the link “U.S. Stock Markets 1871-Present and CAPE Ratio“). For international CAPE Ratios (with some moderate delay, though) I use StarCapital.

Conclusion

It looks like your early retirement plan is in very good shape. Your major risks are currency fluctuations and a bear market early on in retirement. Potentially health care costs later in life. But considering you have two cushions, 1) the potential to raise your withdrawals and 2) the possibility to do some part-time work, there is no reason to delay early retirement anymore. Have fun in Europe! Send me a postcard and Best of Luck!
