I was thinking this week about what I have learned since I started our retirement plan more than ten years ago and since I wrote Next Egg Care roughly eight years ago. I have not radically changed my thinking. If anything, the logic that I set down on paper eight years ago is more solidly fixed in my brain. This post restates the points key to our plan. I list three things that have changed here:
Details:
The objective of our financial retirement plan has not changed. Patti and I should spend the amount that is safe to sell – withdraw – from our portfolio each year. I definitely will not spend – sell securties and withdraw from our portfolio – one dime more than what I calculate as safe, and at the start of our plan it made no sense to me to spend one dime less. We worked hard, saved and invested for decades. We spent alll that effort to live well in retirement. The BIG CONCERN is not to outspend and outlive our money. What’s safe to spend? How do I invest to make sure that amount is safe?
Constant$. I must take inflation out of any calculation for my retirement planning. I must use dollars with the same spending power (constant dollars or Constant$) and real return rates for stocks and bonds to understand what happened or may happen to our portfolio.
The Most Harmful Sequence of Return. Over the last 100 years, stocks average ~7.1% real return per year; on average, they double in real spending power every decade. Bonds average ~2.3% real return per year; on average, they double in real spending power every 30 years.
But the patterns of returns vary widely. We’ve had a 17-year period of 0% cumulative return for stocks and many more years than that for bonds, for example. Now that we are in our Spend and Invest phase of life, we need to understand what happens if we ride the Most Harmful Sequence of return. I can’t get to what is truly a Safe Spending Rate using any other assumption of future returns.
History has to be our guide. I want to use the record of monthly returns for stocks and bonds since 1871: that’s 1,850 months of stock and bond returns. We can assemble over 1,600 20-year sequences of retuerns in the order that they occurred, for example. That’s plenty of history and divergence in results. I have soured on a mathematical approach that many financial planners use to assemble potential return sequences we may face when retired: Monte Carlo Simulation.
Each year, in effect, I assume that Patti and I are riding along the Most Harmful Sequence of stock and bond returns in history. For all sequences of return greater than ten years, this is the return sequence that started January 1969. It’s a stinker. That sequence will deplete a portfolio in the very first year, and a portfolio will never recover and return to its initial value. It will deplete a portfolio deeper than any other sequence of return in history.
Safe Spending Rate (SSR%). I can use FIRECalc or a spreadsheet that I built using the same return data that FIRECalc uses. I can find how a portfolio fares over time for a given spending or withdrawal rate as it rides that Most Harmful Sequence: I’m using a Constant$ withdrawal or spending amount divided by initial portfolio value. I can find the spending rate that ensures I do not deplete a portfolio for the number of years that I pick: that’s my “Safe Spending Rate (SSR%)” for those years. The SSR% increases with fewer target years for ZERO chance for depletion: we need fewer years for ZERO chance for depletion at age 80 than at age 70; our SSR% increases as we get older. Ours started at 4.40% ten years ago and is not 5.50%.
Safe Spending Amount (SSA). Our initial Safe Spending Amount is our SSR% times our initial Investment Portfolio. A 4.4% SSR% times an initial portfolio of $1 million is Constant$44,000 withdrawal or sales of securities to get cash for spending in the upcoming year.
Life-years Risk. I want ZERO risk of outspending our portfolio based on Patti’s life-expectancy. Her life expectancy is three years more than mine. I find the SSR% for that number of years. I don’t use more years for our calculations because I can always lower spending a bit, and that has an outsized effect on extending the number of ZERO years.
Index funds. I get to our SSR% by using market returns for stocks and bonds in the Most Harmful Sequence less an assumption of annual investing costs – that’s typically fund expense ratio. The calculation of what is safe to spend is based on that simple math.
I should never do something that worsens our net returns or adds more uncertainty or variability to returns:
• I can’t of afford to pay a high investing cost – high fund expense ratio: that just lowers the net to us. Advisor fees will hurt our net returns. The Most Harmful Sequence is then more harmful.
• I can’t build a plan that assumes I can beat market returns, because I no longer have logical assumption for the year-to-year returns that tells me how a portfolio will fare riding the Most Harmful Sequence. And the evidence is that that I won’t win that game: over time, only about one in 20 professional money managers return more to their shareholders than the performance of their peer index fund.
I can only invest in Index funds. They are extremely efficient in tracking market returns. Patti and I spend about $300 per $1 million invested (0.03%) for our four index funds that in turn own about 36,000 securities – practically every traded stock and bond in the world. Our 0.03% is 1/20th the amount that many retirees spend. That low cost means we keep more than 99.5% of market returns.
I’d estimate that my investment returns beat at least 95% of all retirees. Only an investor who sharply over-weighted their portfolio to hold US large cap growth funds this past decade could have returned more that the combination two stock index funds that we own.
Stocks are the surprising winner. For a retirement plan, FIRECalc and my spreadsheet show that a greater mix of bonds buys little in terms of the extending the number of years of ZERO chance to deplete a portfolio. On the other hand, a greater mix of bonds sharply lowers the amount you have in all other return sequences. It’s basically a tiny gain of safety in the worst one of 1,600 sequences and a big loss in 1,599 sequences. Bonds are really insurance that you hold to sell when you just don’t want to sell stocks for your spending.
Patti and I started at an overall mix of 80% stocks and 20% bonds. When I sold our Reserve in late 2022 for our spending in 2023, our mix changed to 85% stocks and 15% bonds. That’s where it is today. More bonds than this makes no sense to me.
Reserve. You need a Reserve, although it can test you when stocks are doing well. I started our plan with a Reserve – roughly 5% of our total – that I set aside. I did not include that amount in our portfolio to determine our SSA. That Reserve was roughly one year of spending. My thought was that I would use that Reserve for our spending in a year when stocks cratered; I wouldn’t have to sell stocks when they were low, low, low. I set the definition of “crater” at about -15% real return – a one in ten-year event.
At the end of the first six or seven years of our plan, I thought I was making a mistake. My Reserve barely kept pace with inflation while stocks were running at about 10% real return per year. But then stocks really cratered – about -20% real return in 2022. That was the fifth worst year in my lifetime. I was very happy to use our Reserve for our spending in 2023. I sold no stocks for our spending; I gave them time to rebound, and they rebounded by +25% in less than two years.
Recalculate. I recalculate each December 1 to determine what we can safely spend next year – our SSA: I sell from our portfolio then; I like having the amount we will spend the next calendar year in cash by the end of December. I don’t have to worry about the vagaries of stock returns during the year. On average, I’m giving up some return, since rates on money market average far less than stocks. I don’t care about that.
In a year of poor stock and bond returns, our SSA for upcoming year is the same spending power as this year; it only adjusts for inflation. When stock and bond returns are roughly average, I’ll calculate to a real increase for the next year; I will have earned back more than I sold last year for our spending. The same SSR% results in greater SSA. Our SSR% increases as we age, and that will also help us calculate to a real increase in our SSA.
Our SSA increased in real terms in six of the past ten years. It increased 50% in real spending power. It’s really too much, since we were happy with our SSA a decade ago!
More Than Enough. I no longer sell securities equal to that 50% greater SSA. That means we’re “under-spending” from our portfolio. I can use the inverse of our SSR% to calculate exactly how much I need for the desired amount that I will sell for our spending. I then know our “More Than Enough.” We currently have 15% more than we’d need using our current 5.50% SSR%. I like that cushion.
Fun Money and Physical Assets. I don’t like shifting our financial assets to physical assets – primarily capital additions to our home – now that I’m retired. That just lowers the amount of money we can spend to enjoy.
Over the past decade, I’ve used our HELOC to replace our furnace, two air conditioners, built-in dishwasher and microwave, and pay for two jobs to repair to our stone patio. The interest rate is high now, about 7.5%, and I don’t itemize this expense on our tax return, so that means it’s a 7.5% after-tax cost. That’s $250 per month for our interest-only payment.
I soften the blow by shifting our December cash to get the HELOC balance to nearly zero at the start of the year and it remains low for most of the year. I view the $250 per month that I eventually pay late in the year as “rent” on all those items. I prefer paying that rent and keeping $40,000 to spend on travel and experiences that we’ll remember for the rest of our lives.
Taxes and “Rothification.” I was naïve about taxes ten years ago, and the story of taxes changed fairly dramatically in 2018 when marginal tax rates compressed. You and heirs will keep more from your Roth IRAs than from Traditional IRAs. You want to convert as much Traditional to Roth as you can.
Distributions from Traditional IRAs are taxed at more than 22% because 1) distributions are taxed and also drive up the percentage of Social Security that is taxed; the effect is ~doubling of the 10% and 12% marginal tax brackets; 2) distributions change 0% tax on dividends and capital gains to 15%; 3) greater distributions trip IRMAA (Income Related Medicare Adjustment Amounts) and NIIT (Net Investment Income Tax). Cross a tripwire, and your effective tax rate can easily be more than 26%.
The ideal time is to convert is when you are in the 22% marginal tax bracket and before you start on Social Security. But if you are already on Social Security, you should convert as much as you can to Roth staying in the 22% bracket.
I plan our annual tax return each year so that I can convert Traditional to Roth at the 22% marginal tax rate. Our RMD puts in the 22% bracket; I’m constrained as to how much I convert before I hit tripwires that increase our effective tax rate to sharply more than 22%; typically IRMAA is the culprit.
Conclusion: I thought about how my thinking has changed since I started out our retirement plan more than ten years ago. A number of things are more solidly implanted in my brain. I am firm that our planning has to be based on the assumption of the Most Harmful Sequence of returns in history; I’m clear that we should use the sequence that started in 1969 as the basis for our planning; it’s really a bad one. I’m sour on results from a Monte Carlo Simulation that many financial planners use.
I was naïve about taxes a decade ago, and the tax landscape changed in 2018. You and your heirs keep more from Roth. I put a lot of effort to plan our tax return each year. I convert as much Traditional to Roth that I can at the 22% tax rate.
