Definition
Self-annuitization is a decumulation approach in which an individual withdraws income from a self-managed portfolio designed to approximate the income pattern of a commercial annuity, without entering into any pooled or insured lifetime income arrangement.
Why it matters
Self-annuitization is a common framing in academic and advisory literature for the decision not to purchase a commercial annuity, sometimes called the "do-it-yourself annuity" approach. The term names a recognizable strategy, but it carries a structural ambiguity: the word "annuitization" appears in the term despite the absence of any of the structural properties that distinguish annuitization from drawdown.
How it works
The individual selects a withdrawal rate or income-target rule intended to produce an income stream resembling that of a SPIA or DIA. The portfolio remains owned outright by the individual; capital is not surrendered to an insurer or contributed to a pool. The income produced may track an annuity payment pattern in nominal terms, but the underlying structure does not transfer or pool longevity risk, does not produce or receive mortality credits, and does not provide a contractual guarantee that the income will continue for life. The individual's longevity exposure is identical to any other solo drawdown approach.
In practice
An individual considering self-annuitization is choosing solo drawdown calibrated to mimic an annuity income profile, while retaining ownership of the underlying assets. Useful questions to ask a financial professional include: what survival age does the plan assume, what happens to income past that age, what return assumption underlies the income target, and what specifically is foregone by not pooling or transferring the longevity risk.
In the Longevity Standard Framework
Self-annuitization is structurally not annuitization: it cannot produce true annuitization properties because there is no risk transfer, no pooling, and no mortality credit. The term refers to mimicking annuity-like income from a self-managed portfolio, which the Longevity Standard framework characterizes as solo drawdown. The framework treats self-annuitization as one operational expression of solo drawdown as a strategy class; the cost-of-income framework treats solo drawdown as the baseline against which pooled and insured arrangements are evaluated, and self-annuitization sits within that baseline rather than alongside the arrangements it nominally imitates.
