What it means
Most annuities pay the person who bought them. A reversionary annuity is bought for someone else's future: the payments begin only when the member dies and the designated survivor outlives them.
The structure appears throughout pension law: Illinois's pension code, for example, defines the reversionary annuity as a deferred annuity computed and payable to a designated beneficiary upon the member's death. The pricing is contingent mathematics: the insurer or pension fund weighs the member's mortality against the survivor's, and the premium buys a promise that may never activate if the survivor dies first.
That contingency makes the product cheaper than a joint annuity covering both lives from day one, because nothing is paid while the member lives and the survivor's claim evaporates if the order of deaths reverses. Historically the vehicle served widows' security in eras before joint pensions were standard: a worker's contributions bought a reversionary annuity so the spouse left behind would not fall into poverty.
Modern retirement planning meets the same logic under different names: survivor benefits, contingent annuities, and death-benefit riders all price the identical question of who is left and for how long. The decision trade-offs are actuarial and personal at once: the member sacrifices current income or pays extra premium for protection that only the survivor will ever see.
For a non-finance reader, a reversionary annuity is a pension pointed at the person you might leave: nothing for you beyond the knowledge that the cheque outlives you for them. Pension codes legislate the fine print that matters: whether the designation can be changed, whether the election survives divorce, and what happens when the member dies before retirement with the annuity still deferred.
Group schemes historically used the structure to extend protection cheaply: a small diversion of each member's accumulation funded a meaningful survivor floor across the whole membership. The modern comparison worth running is against level term life insurance, which insures the same loss through a different contract, with premiums that rise against an actuarial price that does not.
Tax treatment follows the annuity wrapper: payments to the survivor carry the character the pension law assigns, which in most systems means ordinary income in the survivor's hands.
In practice
Real-world examples.
Example
A member elects a reversionary annuity so a surviving spouse receives income from the member's death onward.
Example
The survivor dies first, and the reversionary promise expires unclaimed, which is why the cover is cheap. The price of the promise reflected the risk it never ran.
Example
A pension fund prices the benefit from two mortality tables, the member's and the designated survivor's.
Formula
Calculation
Value today = probability the survivor is alive at the member's death x present value, at that date, of the survivor's payments x discount factor from today to the member's death. The cost is lower than a joint annuity because payments never overlap the member's life.
Worked example (simplified, using one assumed date of death): the survivor would receive $20,000 a year for 15 years from the member's death, discounted at 4%. The present value at that date is $20,000 x [(1 - 1.04^-15) / 0.04] = $20,000 x 11.118 = about $222,000.
If there is a 70% chance the survivor is alive then, the expected value is 70% x $222,000 = about $155,000. If the member is expected to die in 10 years, the discount factor is 1.04^-10 = 0.6756, so the value today is about $155,000 x 0.6756 = $105,000. That is far below the $222,000 headline figure, which is why the promise is cheap while the member lives.Case study
Seen in the real world.
This case study is fictional and illustrative. A made-up teacher in Illinois, two years from retirement, reviews her pension options with the fund's counsellor. Her husband's own pension is modest, and her fear is specific: if she dies first, his income halves at the worst moment of his life. The counsellor prices a reversionary annuity election: a slice of her accumulated contributions redirects to a deferred annuity payable to him from her death for the rest of his life.
The arithmetic surprises her: because the promise never pays while she lives, the cost in reduced current benefits is far smaller than the joint-and-survivor option she had assumed was the only route. She elects the reversionary slice alongside a full single-life pension, balancing her income against his protection. Nine years later she dies suddenly, and the deferred annuity activates on schedule, arriving in his account the month after the claim is filed. Her file circulates in the fund's member education as the planning case it was: she insured the one risk her own death would create, at a price set by the fact that she could never collect on it.
Watch out
Common mistakes.
- Confusing it with a joint annuity; the reversionary form pays nothing while the member lives, which is precisely why it costs less.
- Forgetting the contingency; if the designated survivor dies first, the premiums buy nothing further, and the election may be irrevocable.
- Skipping beneficiary review; divorce, remarriage, and death change who should be named, and stale designations are a quiet estate error.
Questions
People also ask.
What is a reversionary annuity?
A deferred annuity payable to a designated survivor only after the member's death, lasting for the survivor's remaining life.
Why is it cheaper than a joint annuity?
Payments never overlap the member's lifetime and never occur if the survivor dies first, so the insurer's expected cost is lower.
Who uses it?
Pension members protecting a lower-income spouse, historically widows' security, now one option among survivor benefit structures.
