personalized mortality factors when establishing
the retirement end date in a financial plan?
To determine this, data is obtained from a financial
planning platform available in Canada. A total
of 31,211 plans met the required filters from
an initial data set of 65,535 plans, which contain
a total of 48,923 retirement end age estimates.
(The number of retirement ages exceeds
the number of plans because some plans were
for two people.)

How to Model the End of Retirement
Even when suitable mortality rates have
been determined, there is no consensus approach
to estimate the length of retirement in a
financial plan. In other words, planners using the
exact same mortality table could reach very
different conclusions about the suitable length
of retirement for planning purposes.

E X H I B IT 3 includes the distribution of retirement
end age assumptions in financial plans by
gender. The vast majority (97.2%) of retirement
end age assumptions were multiples of 5, between
the ages 75 and 100, which is why only these
multiples are included in E X H I BI T 3 .

The distribution of retirement income ages is very
similar by gender and age, as well as by
assumed retirement start age. Approximately 70%
of retirement end ages were 90, whether male
or female, and approximately 20% of retirement
ages were age 95. The average assumed
retirement end age only increases by approximately
two years for men, moving from a start age of
50 to 70 (89.8 to 91.9) versus 0.9 years for women
(91.1 to 92.0). These findings suggest financial
for clients, at least in this data set.

In the original paper, I conducted an analysis
to determine how long the retirement period
should last once a personalized life
expectancy estimate has been determined.
In theory, considering the full distribution
of mortality rates, like in EXHIB IT 1 ,
would be the best way to go, but because the
information is not always made available
in online tools, life expectancy is used as the
base value.
The analysis suggests that adding five years
to a personalized life expectancy estimate
would be a way to estimate an appropriate
retirement period for a single individual. For joint
households, eight years should be added
to the longest life expectancy of the two members
or three years if the retirement period
considers the actual joint survival probabilities.
(For additional context on these results, I suggest

Estimate Accuracy Has a Considerable Impact
Personalized mortality estimates can have
a considerable impact on the results of a financial
plan. The assumed retirement period not only
affects things like required savings and
optimal spending, but also important decisions,
such as when to retire. Decisions about how to
fund retirement-whether to delay claiming
Social Security benefits, to purchase an annuity,
and others-will also be affected. Evidence
suggests that while subjective estimates may
be relatively accurate on average and that
households appear to do a relatively good job
considering various objective factors (such
as health status), there are often significant errors
in individual forecasts, and households do
not appear to correctly consider all the relevant
objective factors (such as income). Therefore,
financial planners need to educate themselves on
how to better model and personalize mortality
assumptions into financial plans. K
