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…

Mr. and Mrs. Shirt’s situation:

Both Mr. and Mrs. Shirts will turn 36 in a few months. Some more background in Mr. Shirt’s words:

The core of my debate is I’d really hate to work full time for an extra nine months, especially if I don’t enjoy my job, then turn around and make enough money in early retirement/second career to have wasted that time in my life.   I enjoy the “core” of what I do, but I dislike the hours and am working for a megacorp that’s dying in mediocrity.  Not dying in a sense of bankruptcy/pension risk, but dying in terms of shareholder return, innovation, and its like watching a car wreck happen in front of you without being able to do anything.

My wife also experienced a scary injury (spinal CSF leak) that cost us almost a year of our healthy life and goals and there is a risk of this happening again.  She’s most of the way through her recovery, but its given me a stronger sense of “do I really want to contribute another eight months of my life, the healthiest months of my life, to a megacorp for gigantic stacks of cash”, especially when I might make some $ in retirement.  I also feel more fortunate than most because between social security, a traditional pension, and the ability to just move if a high housing cost area doesn’t work out, I am at less risk of starving in retirement than the average person.

I could probably “pack it in” and check out mentally and make it until the 2019 date, but I run a team that I care about.  Its very difficult to do this when I’m not wired for it.  I also wouldn’t mind supporting some charitable ventures with the additional money, especially as it relates to medical issues.

Wow, thanks for your honesty! If work is no longer fun then nine more months can be pretty painful. We’ll look into the tradeoffs below. Where do we stand with the net worth? Here are the numbers as of 2017 year-end:

After-Tax $253,856

IRAs $830,551

HSA $59,501

Deferred Comp $163,551

Home Equity $175,234      (we’ll count this in the NW, more details below)

Other (liquid/cash) $36,651

Total: $1,519,344.00

I ascertained that the Deferred Compensation package is still pre-tax. Specifically, upon retirement, the deferred comp will be paid out over the next 15 years, and each installment is still subject to income taxes (both federal and state), but not subject to payroll taxes. A little bit like a 401k plan with a forced liquidation over 15 years – and no penalty for withdrawals before age 59.5!

How about additional contributions between now and the two alternative retirement dates?

If I work until June of 2018, contributions to the accounts will be as follows: 401k: $25,700, Taxable: $37,200 (mainly RSUs vesting which I immediately sell and invest), Deferred Comp:  $47,900.  (Total: $110,800)
If I work until March of 2019 contributions look like this, which is inclusive of the numbers referenced in the June 2018 example above: 401k: $52,300, Taxable:  $103,820, Deferred Comp:  $121,700.  (Total: $277,820)

OK, I can see why you’re troubled! Just nine more months of work and you can cash in another $167k. You’d be leaving more than $18k a month on the table!

How about the housing situation? The house with $175k home equity in their current location will be sold and Mr. & Mrs. Shirt will move to another state:
We don’t know our final destination at retirement.  The two top candidates have very different costs:
  • Eastern Appalachian Mountains (North Carolina):  I’d like to run the estimate on a Home Price of $300,000 or rent of $1,750.
  • Hawaii:  Home Price of $750,000 or rent of $3,250/mo
It is highly unlikely we would buy our retirement home while working, which throws a wrench in the ability to finance it without employment.  We could buy the house in the Appalachian option, but would be renters with Hawaii.

Nice! I think that owning a house in early retirement is probably the best option to hedge against rental inflation and Sequence Risk. For this exercise, I will work under the assumption of owning a home North Carolina. That’s because – sorry to break the news to you – but Hawaii seems too far out of reach, both as a homeowner and as a renter. You might want to consider staying in NC for a while and maybe budget for a vacation rental every year or two!

Retirement Budget

Our “core” expenses haven’t really ever exceeded $25,000/year.   I define core expenses as everything except housing and healthcare.

That’s pretty low! Great job! I will budget an additional $20k in annual expenses for healthcare and housing expenses. About $10k each for healthcare (premium and out-of-pocket) and housing: property taxes, maintenance, repairs, etc. We will see below that your taxable income, even when doing Roth conversions, should stay below the Obamacare subsidy cliff, in your case $64,080 for a two-person household in 2018 (source: NerdWallet), hence, the relatively low health care expenses

How about supplemental income:

I don’t currently have a side hustle. My employment strictly prohibits that. This is something that “you don’t know until you know”, but I feel fairly confident I will earn something in retirement. Project work for clients, director’s fees, I’m a complete business nerd and am well connected in two large cities. My wife is a veterinarian by trade and maintains her licenses, it is very easy for her to pick up a half-day Saturday for $200-$350/day for extra money.

That’s nice to know that you’re flexible in retirement. Not everybody wants to chip in during retirement. I will assume that in the 2018 retirement scenario you will generate a small supplemental income. That will not be necessary for the 2019 retirement scenario.

How about Social Security and pensions?

I ascertained from Mr. S that he’s eligible for about $19,900 in annual Social Security at age 67 as of 12/31/2017. That figure goes up to $21,000 and 22,200 when working in 2018 and 2019, respectively, and putting in another year or two worth of Social Security contributions up to the cap.

I had only approximate numbers for Mrs. Shirts but I assume that she is eligible for $10,800 of her benefits. If Mr. Shirts works until 2019 then half of his Social Security is actually larger Mrs. Shirt’s own benefit. Also, given that you’re both still pretty young I’d like to apply a 25% haircut to your benefits to account for future benefit cuts:

Social Security Assumptions. Age 67.
Mr. Shirts is also eligible for a pension.  $1,128/month if he quits in 2018 and $1,250 if he quits in 2019. This amount is not CPI-adjusted! Ahhh, those cushy perks of working for a “dying megacorp!”

Safe Withdrawal Rate Calculations

I will run the numbers twice, once for a June 2018 retirement date and once for March 2019 retirement with the additional savings. Both calculations require some assumptions about capital market returns between now and then, so I’ll try to be cautious and conservative with the capital market projections.

Retire in 2018:

The portfolio grows to just under $1.7m. Net of the purchase price for the house, that leaves about $1.375m in today’s dollars.

Projecting the portfolio value as of 6/30/2018. I assume that half of the contribution is invested at the beginning of the year and the other half is deposited as a lump on 6/30.

Given that the asset position is a little bit thin and you indicated that you’re open to generate some supplemental income, let’s assume you bring in another $1,000 per month for five years, starting in 2019 (when you’re in a lower tax bracket), adjusted for inflation. I found the $1,000 figure will generate a 4% SWR and it’s also easily attainable with a few side gigs here and there, especially with Mrs. Shirt’s weekend vet gigs. You can go to the spreadsheet and play around with the numbers and see how the SWRs change.

Some additional assumptions:

The Google Sheet is the usual setup as I explained in Part 7 of the SWR series:

Google Sheet with simulation results (2018)

If you like to make changes, please first save your own copy!!!

Let’s check out the results:

Main Results when retiring in 2018.

The Failsafe is 3.88% (occurred during the 1965/66 retirement cohorts, exposed to the 1970s/early 80s mess). A 4% WR would have generated a 5% failure rate. Pretty good! Overall, this is not too surprising. The non-COLA pension and Social Security are 18 and 31 years away, respectively, too late to compensate for a drawdown early on, but with the supplemental income, you get to your desired 4% SWR. Relative to your $1,375,000 initial portfolio, that’s $55k of annual cash flow. Budget about $5k for taxes and you can spend around $50k per year. Even the failsafe 3.88% rate would leave you with $53k, probably $48k after taxes.

So, just from the backtesting/simulation perspective your June 2018 is a “go” though there are some wrinkles as I will detail later!

Retire in 2019:

With the additional contributions and some moderate capital returns (assuming 4% nominal over the 9 months for equities), we now got about $1,580,000 in the portfolio. This is already after paying for the house!

Google Sheet with simulation results (2019)

I maintain the 70/30 allocation assumption. Also, the “stickler” that I am, I set the horizon to 711 months, 9 months shorter than in the other simulation just to be consistent and comparable to the other scenario! The Results:

Main results when retiring in June 2019: The 4% Rule is not safe without supplemental income!

Now we have a slightly lower safe withdrawal rate, but with the additional financial net worth ($1,581k), those lower rates still generate about $58,500 p.a. for the failsafe and about $60,500 for the 3.83% WR. That’s significantly more. After tax, you’re now looking at a sustainable consumption of about $53k-$55k p.a., depending on how “safe” you want to be. It’s about a $5k cushion per year over and above the 2018 retirement scenario, every year, in a 50-60 year retirement. For 9 more months of work.

OK, I’ve talked to people who hate their work but I’ve never met anyone who’d walk away from a 10% boost to the post-retirement consumption for nine months of work. Check out the Grumpus Maximus blog. He faced the problem of grinding through not months but years of a tough job for that “Golden Albatross” of a nice government pension.  Incidentally, Grumpus was the guest on the ChooseFI podcast episode 57 on Monday!

Cash Flow Simulations

As always, I’m interested in how the withdrawal plan would work with the actual portfolio with all the different accounts spread over taxable, tax-deferred and tax-free accounts. I will do the analysis for the 2018 retirement date using the following assumptions:

Cash Flow Simulation, part 1.
Cash Flow Simulation, part 2. Variables shaded in orange are the numbers that Excel solves for to equalize net income and consumption target!
Cash Flow Simulation, part 3: MAGI stays below the Obamacare Cliff!

Results:

The plan seems to work. You even grow your real portfolio value from $1.3m in 2019 to about $1.5m by age 70. By that time, you’d have shifted your 401k to the Roth and you should have no issues with Required Minimum Distributions. In fact, after age 67, your portfolio will keep growing because Social Security kicks in. The plan also generates a natural glidepath to 100% equities. If you’re not comfortable with that you can of course shift to more bonds inside your Roth once the Roth becomes the primary retirement account. If for some reason the Roth conversion ladder doesn’t deliver enough cash flow (remember, only the principal from 5+ years ago is fair game), you might consider the 72(t)/SEPP route as a last resort!

Conclusion

I think you’re likely ready to retire either way. Of course, one concern is your wife’s health. Another costly health episode could lower your combined supplemental income potential and also bust your budget in early retirement. Two bad risks with a correlation of one! This risk alone would entice me to just delay retirement by another short 9 months.

The other reason to hold off retirement just a little bit longer is the housing situation. Retiring in 2018 would seriously deplete your taxable savings and you’d have to really cross your fingers that the Roth Conversion Ladder works the way you planned. But then again, you can always use the 72(t)/SEPP route to tap the 401k savings before age 59.5.

Another unpredictable risk is the survival of the Obamacare subsidies. I’m pretty confident that some form of O-care will be permanent, but the subsidies could easily become a lot less generous over time. As we saw with the GOP tax change, politicians can take away “tax hacks” like the state and local tax deduction with a vote in each chamber and a president’s signature. I would not tie my retirement to the survival of those healthcare subsidies! Just look at the mortgage interest deduction which has become essentially useless for most taxpayers due to the high standard deduction. In the next tax reform, this deduction will go out the window forever because so few people will miss it then. Who would have thought ten years ago that the formerly sacred cow of the mortgage deduction can ever go away?

So, whatever retirement date you pick, best of luck! Keep us updated!
