- what the approach is,
- common misperceptions about it, and
- why we call it the Actuarial Approach.
The Actuarial Approach is the use of basic actuarial principles to accomplish one’s personal financial goals. For many years, actuaries have been helping sponsors of financial systems accomplish financial goals using basic (or fundamental) actuarial principles (or concepts). The Actuarial Approach advocated in this website applies many of these same principles to personal financial goals. These fundamental actuarial concepts include:
- Making assumptions about the future
- Time value of money
- Concept of probabilities
- Use of actuarial present values
- Use of a generalized individual model that compares assets with liabilities
- Periodic gain/loss adjustment to reflect experience different from assumptions (annual valuations), and
We believe these tried and tested principles are mathematically superior to the strategic withdrawal plans advocated my many retirement experts and academics.

Common Misperceptions About the Actuarial Approach
We find that there are several misperceptions about the Actuarial Approach and, for the most part, they all stem from the same source: individuals believe the Excel workbooks we provide in our website and our recommended assumptions comprise the Actuarial Approach. It is important to note that we provide the workbooks and recommended assumptions simply to make it easier for users to apply the following basic actuarial formula, which compares one’s assets with one’s spending liabilities:
- Because the Actuarial Approach uses deterministic assumptions, it is not as robust as approaches that use Monte Carlo modeling and stochastic assumptions
- Because the assumptions used in the Actuarial Approach are conservative, the results are too conservative
- Because the Actuarial Approach uses a fixed lifetime planning period rather than probabilities of death, it is not sophisticated enough
- Because it determines spending budgets on a pre-tax basis, it is not useful, etc.
Why do we call it the Actuarial Approach?
We call it the Actuarial Approach for several reasons:
- The name is sexier and more concise than “the approach that uses basic actuarial principles to accomplish personal financial goals”
- It is consistent with the approach used by actuaries to help sponsors of financial systems accomplish financial goals
- We are two pension actuaries who used a similar process for guiding pension plan sponsors
- It utilizes more of the basic actuarial principles than almost all the other approaches currently in use.
Actuaries use basic actuarial principles to help keep many financial security systems sound and sustainable. These same principles can be used to help individuals achieve financial goals. We encourage individuals and their financial advisors to consider using these time-tested and proven basic actuarial principles in their financial planning, at a minimum as a supplement to what they are currently using. To paraphrase Juliet, “That which we call the Actuarial Approach by any other name just makes good financial sense.”
