Annuity Ladder

Buying an annuity is a one-way bet on today's rates and today's fund value, and committing an entire retirement fund on a single afternoon concentrates every risk in one moment. A ladder breaks that moment into rungs: the saver converts slices of the fund into income at intervals - some now, some in three years, some in eight - and each slice locks its own rate.

Rate risk softens immediately, since if rates rise, later rungs buy bigger incomes, and if rates fall, the earlier rungs already secured better terms, and regret is halved either way. Age works in the ladder's favour too, because annuity income per dollar rises with the buyer's age, so the rungs purchased later in retirement are intrinsically cheaper income.

The structure also staggers irreversibility, as each conversion is a smaller one-way door and the unconverted balance stays liquid and inheritable until its rung arrives. Ladders answer inflation in a crude but useful way, since later purchases can be sized larger, restoring purchasing power that the earlier fixed cheques have lost.

The strategy mixes product types too: immediate annuities can form the early rungs, while deferred or longevity annuities wait at the top to switch on deep into old age. A longevity annuity is the classic top rung, bought at 65 but paying only from 85, which insures the late years cheaply because the insurer keeps the money when buyers die before the start date.

Costs deserve honest counting, because each purchase carries its own margins and possible fees, and five small annuities may price worse than one large one, so quotes belong side by side. Tax wrappers still apply per contract, as each rung is its own annuity with its own exclusion ratio and reporting, so the paperwork multiplies with the rungs even as the risk divides.

The ladder is a plan, not a product, and it needs a schedule, target dates and review points written down, or the later rungs quietly never get bought. Sequence matters in design too, since early rungs should cover non-negotiable spending first, while later, cheaper rungs can fund the flexible lifestyle layer that markets cannot be trusted with.

For a manager advising staff at retirement, the pitch is behavioural as much as financial: staging conversions turns one terrifying permanent decision into several smaller, checkable ones. Pair each rung with a calendar date and a named reviewer, so the plan survives changes of mind and market mood.
