Living The Same,
Longer

The first time it happened was in the 1990s when Lynn Hopewell said, ÒWhy not
Monte Carlo simulations?Ó
Hopewell, an ex-CIA communications engineer,
entered the financial planning business in the 1980s, and after experimenting
with popular planning methodologies for a decade and uncovering their inherent
faults, brought his Harvard MBA education to bear on the problem. In an October
1997 article in the Journal of Financial Planning entitled, ÒDecision Making
Under Conditions of Uncertainty: A Wakeup Call for the Financial Planning
Profession,Ó Hopewell (who passed away in March 2006) questioned the use of
straight-line investment return assumptions by every existing financial
planning software package (at the time).
He said, in so many words, ÒWeÕve already
got a better system that statisticians have known about and applied for
decades—Monte Carlo simulations. Why are we using straight-line
assumptions when Monte Carlo simulations already exist?Ó Today, you would be
hard-pressed to find financial planning software that doesnÕt include a Monte
Carlo option.
ThereÕs a phenomenon at work here, which is
that our industry has matured in something of a vacuum and is in danger of
developing Òbest practicesÓ that donÕt always serve the best interests of
advisors or their clients. Real innovation often comes from eclectic influences
outside the industry, which is why we should pay attention to what Dr. Laurence
Kotlikoff has to say when—as Hopewell did—he asserts that weÕre
doing it all wrong.
What Dr. Kotlikoff doesnÕt like about
modern-day planning software is evident in the way we use it. The drill usually
goes something like this: We input demographic information for the clients,
along with their income, expenses, assets and assumptions including inflation
rate and return on investment. Our software then shows us the levels of assets
that will be saved or consumed between now and death. If we lower our spending
assumptions or fiddle with other variables, assets will endure for longer or
shorter periods. By varying our many assumptions, we attempt to develop
strategies to help our clients achieve their goals without prematurely
consuming all their assets.
ÒThere are several problems with this,Ó says
Kotlikoff. ÒWith [traditional planning software], risk comes from investments
and translates into running out of money; with my methodology, the risk isnÕt
running out of money, but having less to live on. Traditional planning
methodologies stick with the clientÕs assumed living expense target even if the
market crashes and the clientÕs assets drop. Or, they direct the client to
spend 4% of his assets every year no matter what happens [externally]. In real
life, the client would adjust his living expenses downward in response to an
external event like a market crash.Ó In other words, traditional planning
software doesnÕt take into account human reactions; it goes only as far as
Òstatic thinkingÓ can take it.
To correct for this inadequacy, Dr.
KotlikoffÕs own financial planning software—E$Planner
(www.ESPlanner.com)— relies on Òdynamic programming,Ó a mathematical
process for solving problems involving sequential decisions. ÒDynamic
programming considers the future decisions we are likely to make in order to
determine a recommended course of action in the present,Ó says Kotlikoff,
Òthereby improving upon traditional planning methods by more nearly
approximating the way we make decisions in real life.Ó
When Hopewell introduced Monte Carlo
simulations to the financial planning world, he was drawing on a statistical
sampling method that had been around since at least 1930 (although it didnÕt
begin to be widely used until 1945 with the advent of the first electronic
computers). Similarly, dynamic programming has been around since the 1940s when
it was first developed by mathematician Richard Bellman. He used it a decade
later in his work with the RAND Corporation, and it became widely used by
economists such as Paul Samuelson and Eugene Fama in the late 1960s and early
1970s.
Kotlikoff, like Hopewell, has simply
introduced to the planning profession from the outside world a better way of
doing what we do — with a twist. ÒWe have a patent for the particular
type of dynamic programming used in E$Planner,Ó says Kotlikoff. ÒWe have a few
dynamic programs iterating with each other.Ó Without that refinement, it would
take hours to run a plan, much as Monte Carlo simulations sometimes took
minutes instead of seconds in the software packages in which they were first
adopted.
So if traditional planning software focuses
on the sufficiency of a clientÕs assets, E$Planner focuses on the sustainability
of the clientÕs living standard and on his optimal life insurance coverage. In
fact, by all appearances, it is the implementation of Nobel Prize-winning
economist Franco ModiglianiÕs Òlife cycle consumption smoothing model.Ó
So how could anyone refute E$PlannerÕs approach? The software has an
authoritative foundation and its approach is exceedingly logical. Yet,
E$Planner is surrounded by controversy. Why? Because, in many cases, the
program tells clients to save less and buy less life insurance than would most
traditional planning analysis. Advisors like the concept behind E$Planner, but
choke on the results because theyÕre sometimes so out of tune with the answers
advisors are used to seeing.
In his February 2006 paper entitled, ÒIs
Conventional Financial Planning Good for Your Financial Health?Ó Dr. Kotlikoff
compares the results of E$Planner with four Web-based retirement calculators
from Fidelity, American Funds, Vanguard (using Financial Engines) and
TIAA-CREF, and found these calculatorsÕ recommended savings levels to be
between 36% and 78% higher than those of E$Planner.
Why does this occur? Because all financial
planning is geared to consumption smoothing, that is, determining what living
standard can be sustained both pre- and post-retirement. Says Kotlikoff,
ÒHowever, [using traditional methods] the client is forced to set his own
retirement spending targets consistent with consumption smoothing, and this is
incredibly difficult to do. Even small targeting mistakes of as little as 10%
can lead to enormous mistakes in recommended savings and insurance levels.Ó
What exactly then is the output from
E$Planner that forms the crux of the advisorÕs recommendations to his clients?
Consumption. Kotlikoff defines consumption as all expenditures by the household
other than special expenditures (e.g., buying a new car every X number of
years), housing, taxes and life insurance premiums. By taking into account the
clientÕs current and future economic resources, current and projected
demographics, current and projected housing spending, special expenditures,
taxes, life insurance premiums and any expectations the client has about
increasing his future standard of living, E$Planner spits out a recommended
annual consumption amount the client should be able to maintain indefinitely.
Recommended annual consumption also forms the benchmark for Òwhat-ifÓ
comparisons. The user can test the effectiveness of competing investment
strategies, Social Security benefit timing decisions and the like by comparing
the recommended annual consumption levels for one strategy versus another.
Charlie Ryan, a research analyst with The
Family Firm, a fee-only advisory firm in Bethesda, Md., has done approximately
20 plans with E$Planner and says it has worked well for clients. ÒMost clients
have one general desire: to find the highest sustainable standard of living
throughout their lives, and thatÕs just what E$Planner does. You tell it the
clientÕs income, assets and mandatory expenditures like housing, transportation
and non-life insurance, and it computes a level of allowable, non-mandatory
spending that is constant throughout the clientÕs lifetime. E$Planner refers to
this non-mandatory spending as ÔconsumptionÕ or Ôstandard of living.ÕÓ
Ryan offers an example of a client with no
savings, $50,000 in income, mandatory housing expenses of $12,000 a year and
taxes of $8,000 a year. ÒWith $30,000 left, E$Planner will compute a
sustainable, unchanging level of discretionary spending through retirement all
the way to the end of the plan. For the sake of this example, letÕs say that
level is $20,000 with the remaining $10,000 going to savings.Ó
Next, says Ryan, letÕs enter a new
assumption into E$Planner, namely that the client will get a $30,000 pay raise
in five years; how would that change E$PlannerÕs recommendations? ÒE$Planner
will recommend a higher level of discretionary spending now, perhaps saying all
income should be spent now with no current contributions to savings. Why?
Because more savings can occur later from the clientÕs higher pay, and the idea
is to smooth the clientÕs standard of living over time.Ó
Rick Miller of Sensible Financial Planning
in Cambridge, Mass., is another big fan of E$Planner. ÒWhen I started in the
business five years ago, I looked at everything; E$Planner was the only
software that rapidly delivered comparative solutions for a variety of
scenarios. I donÕt have to guess at how much people can spend in retirement.Ó
Miller points out a feature of E$Planner
that would seem to fit well with the emerging emphasis on decumulation planning
for baby boomers. Anyone whoÕs worked with retired clients has heard questions
like, ÒCan I afford to buy a new car?Ó or ÒIf I spend $10,000 on my vacation
this year, is that too much?Ó ItÕs easier to answer these questions if your
software is telling you what your clientÕs sustainable standard of living is as
opposed to how long his assets will last.
How does Miller explain E$PlannerÕs results
to clients? ÒI say weÕve added up all your resources, spending on things you want
to do that is Ôlumpy,Õ or not what you would ordinarily spend in a year, as
well as housing and other expenses that are likely to change in a predictable
way over your lifetime. We subtract the total of these items from your
resources, and whatÕs left is what you can spend on day-to-day living.Ó On that
basis, says Miller, he can then go on to answer client what-if questions, like
the impact of retiring earlier or later, sending kids to one college rather
than another, and so on.
And speaking of college, E$Planner doesnÕt
have a college planning function, per se. Nor does it address a clientÕs
possible need for disability insurance or the pros and cons of different types
of executive compensation (stock options, restricted stock, deferred comp,
etc.). It only does these things if the parameters of these modeling exercises
can be fit into the E$Planner framework.
For example, E$Planner can answer the
question, ÒShould I enroll in college, take a student loan, and forgo earning
income for the next four years of my life in order to get a college degree that
will enable me to earn more in the future?Ó Says Kotlikoff, ÒThe question isnÕt
whether college grads will earn more once they start working. ItÕs whether they
can achieve a higher living standard over their lifetimes given the costs of
attending college.Ó
If, says Kotlikoff, we assume 18-year-old Rebecca is thinking about borrowing
to attend a $40,000/year college and expects, after graduating, to earn $22,600
more than a high school graduate (the average earnings spread as computed by
The College Board, which administers the SAT exams), the answer isnÕt so
clear-cut. Why? Because the college loans will drag down net consumption for
years. Obviously, much depends on the cost of the education, RebeccaÕs major
and her resulting earnings potential, but just knowing college grads earn more
than high school grads isnÕt enough, by itself, to recommend the college
experience. Says Kotlikoff, ÒBorrowing to raise your future labor earnings is
not much different from borrowing to invest in the stock market. They both
entail risk.Ó
If a planning issueÕs parameters canÕt be
fit into the E$Planner framework, then the question goes unanswered. Bedda
DÕAngelo of Fiduciary Solutions in Durham, N.C., says, ÒE$PlannerÕs good with
income taxes and cash flow, but there is no way to model different types of
trusts and estate planning tools. In my opinion, E$Planner is less
comprehensive than other commercial programs.Ó
Upon reviewing E$Planner for use in his company, Steven Weydert of Bowyer,
Weydert Wealth Planning Partners Inc. in Park Ridge, Ill., also reached the
conclusion that there are simply too many planning areas not covered by the
software. ÒConsider this,Ó says Weydert. ÒToday there are nearly two dozen
discussion forums on E$PlannerÕs Web site. I randomly clicked on the one
entitled ÔHow Do I Use E$PlannerÕ where I found eight more sub-topics. I then
clicked on ÔHow Do I Model Contributions to Health Savings Accounts?Õ and the
response from Professor Kotlikoff was: ÔWe have not yet formally included HSAs
in E$Planner. We will likely do so in the near future. In the meantime, enter
the contributions you plan to make as Ôspecial expendituresÕ that are
excludable from AGI.Ó
In other words, Weydert found Òwork-aroundsÓ
for E$Planner but not specific attention to a number of important planning
areas. In addition to HSAs, he says E$Planner lacks a specific planning option
for reverse mortgages, nondeductible IRAs and 529 plans, to name just a few.
Is this as big a problem as DÕAngelo and Weydert make it out to be? It really
depends on the nature of your clients and on your philosophy of financial
planning. Says Miller, ÒIs it comprehensive enough? IÕm not sure because
thereÕs no perfect financial planning program out there. As for E$Planner, I
believe its benefits outweigh its deficits. It covers the crux of what we do.Ó
A competing software
program—MoneyGuidePro—has acquired thousands of users without being
comprehensive. Although it has taken on added functionality since its
introduction, MoneyGuidePro has always focused primarily on one thing, which is
answering the question, ÒCan my client get through his lifetime without running
out of resources?Ó Although its methodology is different from that of
E$Planner, MoneyGuidePro appeals to a broad spectrum of planners who are more
concerned with getting the crux of financial planning right than generating a
ÒcomprehensiveÓ plan.
Another criticism voiced about E$Planner is
that it works, but not for all clients. Says Scott Neal of D. Scott Neal Inc.
in Lexington and Louisville, Ky., ÒIf E$Planner is controversial, itÕs because
it deviates from our standard stuff, not because itÕs fundamentally flawed in
some way. Like many tools we employ, it has a place and application for which
other tools are inappropriate.Ó
Neal goes on to say that, when working with
a client for the first time, he looks for what might be subtle signs of the
clientÕs strategic goal before getting into more precisely defined goals. ÒFor
example, I listen for clues that would help me determine whether the client
fits into one of the following four camps: a) client wants to maximize lifetime
security, b) client wants to maximize lifetime consumption, c) client seeks
optimal lifetime income smoothing, or d) client wants his planning to help him
achieve something intangible, like power, leadership, recognition or fame.Ó
Obviously, says Neal, Dr. KotlikoffÕs
software meets the needs of the third type of client. ÒMost clients come to us
either in Camp A or B and are, in fact, often in conflict about which of those
they are in. For the few who truly fit in Camp C, E$Planner is the tool of
choice.Ó
Ryan believes the choice of software
programs depends on the clientÕs level of wealth. ÒE$Planner works great for
folks with moderate incomes and savings. It does not work well for very
high-income or high-net-worth clients. Suppose a retired client shows up with
$10 million in savings. Since E$Planner calculates the highest possible level
of spending, it might recommend a level of discretionary spending thatÕs
substantially higher than the clientÕs actual spending.Ó
That said, my guess is thereÕs a work-around
for that situation, too. Although this article seeks to discuss E$PlannerÕs
philosophical underpinnings more than its nuts and bolts, this author has
tested the program for himself (a pre-retirement ÒclientÓ) and for one
post-retirement client, finding that it handles both scenarios quite well. Yes,
there are some bugs (e.g., wrong names sometimes print out on reports) and
minor inconveniences (E$Planner doesnÕt flag a userÕs failure to fill in
certain critical assumptions or data and, subsequently, may give the user
wildly off-base recommendations necessitating a wild goose chase through the
programÕs input screens to find the incompletes).
Nonetheless, it does seem likely Dr.
KotlikoffÕs planning methodology, if not his software, will continue to attract
attention and will very likely impact the financial planning software market
within the next few years. Says Miller, ÒNew ideas have trouble gaining
traction in the [financial services] market, and weÕve all got our own ways of
doing things. Someone could theoretically come out with planning software that
did everything and people would still be slow to adopt it.Ó As for Miller, he
says his own business processes are built around E$Planner and heÕs sticking
with it.
If you want to learn more about dynamic
programming or living-standard-centric planning, youÕll find the prolific Dr.
KotlikoffÕs many writings online, and his next book — Spend Till the End
— will be published by Simon and Schuster in the spring of 2008.
