Annuity Persistency

Definition

Annuity persistency is the rate at which annuity contracts remain in force over time without being surrendered, lapsed, annuitized into income, or otherwise terminated, typically measured as a percentage of contracts (or premium dollars) remaining in force at successive contract anniversaries.

Why it matters

Annuity persistency is a structural fact about the in-force book of a carrier — it shapes the carrier's investment yield economics, its reserve adequacy, and the pricing it can offer on new business. The persistency assumption is embedded in any annuity's pricing model and is one of the inputs that determines the embedded spread the carrier requires to support the contract.

How it works

Annuity persistency is measured by tracking how many contracts (or how much premium volume) remain in force at successive measurement points after issue. A contract exits the in-force book when the owner surrenders it, when it lapses for failure to maintain required premium or charges, when it is annuitized into the income phase, when the owner dies before annuitization, or when it is exchanged into another contract under a 1035 exchange. Persistency is typically reported as a percentage — for example, a 92% persistency rate at year three means 92% of contracts (or premium) issued three years prior remain in force at the three-year measurement point. Persistency rates are typically lower in the early surrender period (when surrender charges decline and the contract becomes accessible at lower cost) and higher after the surrender period ends. Persistency varies substantially across product types — fixed annuities, fixed indexed annuities, variable annuities, and immediate annuities each have characteristic persistency curves. Carrier pricing models build in persistency assumptions; if actual persistency deviates from the assumed curve, the carrier's profitability and reserve adequacy can shift materially.

In practice

For an individual considering an annuity purchase, persistency is most relevant as context for the surrender charge schedule — the surrender period is the structural feature most directly linked to persistency assumptions, and the schedule reflects what the carrier needs the contract to do to recover acquisition costs and earn its expected return. The persistency of similar contracts in the carrier's broader book is generally not disclosed in product materials but is part of the carrier's pricing assumptions; a professional asking the carrier about persistency assumptions on the specific product under consideration is asking a structural question rather than a marketing question. For plan fiduciaries evaluating in-plan annuity options, persistency dynamics matter at the plan level — group placements may have different persistency profiles than retail placements, and that difference can affect long-term pricing terms.

In the Longevity Standard Framework

Annuity persistency is supporting context for the Longevity Standard framework rather than a claim characteristic. The persistency assumption is one of the inputs that determines the embedded spread the carrier requires on a contract; higher assumed persistency tends to reduce the carrier's required spread (the carrier recovers acquisition costs over a longer expected in-force period), while lower assumed persistency tends to increase it. The cost-structure property of the resulting contract is downstream of the persistency assumption: the embedded spread, the surrender-charge schedule, and the guarantee-charge level all reflect the carrier's persistency model in pricing. In the realized value calculation, persistency dynamics do not appear directly but are absorbed into the insurer load, which captures the full gap between the contract's pricing and the frictionless pool benchmark regardless of the specific carrier-side assumptions producing the load.
