555 / What is the difference between a longevity annuity and a deferred annuity?

By contrast, a longevity annuity generally provides no access to the funds during the deferral period, and does not allow the contract to be annuitized until the owner reaches a certain age (usually around 85).

In other words, many taxpayers purchase traditional deferred annuity products with a view toward waiting until old age to begin annuity payouts, but they always have the option of beginning payouts at an earlier date. With a longevity annuity, there is generally no choice, but this also allows for larger payments for those who do survive to the starting period; as a result, for those who survive, longevity annuities typically provide for a larger payout (often, much larger) than traditional deferred annuity products.

Most taxpayers who purchase longevity annuities do so in order to insure against the risk of outliving their traditional retirement assets. The longevity annuity, therefore, functions as a type of safety net for expenses incurred during advanced age. Where a deferred annuity contract may be more appropriately categorized as an investment product, the primary benefit of a longevity annuity is its insurance value.
