Life Annuity or Retirement Withdrawal Portfolio
An annuity guarantees income but locks up capital: measure what you give up in liquidity and estate value.
Published 2026-07-21
The life annuity and the drawdown portfolio face off in a false duel: the two formulas trade different risks for different freedoms, and the best answer often combines them. The annuity transfers market and longevity risk to the insurer, income guaranteed for life; in exchange, the capital ceases to exist — illiquid for emergencies, absent from the estate except through an option paid for in reduced income. The portfolio keeps liquidity, adjustable withdrawals and transferable capital; in exchange, it retains market risk — the sequence of returns first — and behavioural risk. The combination is calibrated through expenses: the gap between essential needs and existing guaranteed income — public plans and employer pensions — defines the annuity's precise mandate, nothing more, the portfolio keeping the rest. This article prices both formulas on a typical case and guides the calibration of a guaranteed floor beneath a flexible upper storey.
Price what the annuity actually guarantees
A life annuity exchanges capital for income guaranteed for life, and the first step is obtaining real quotes rather than estimates: the monthly amount varies appreciably between insurers for the same capital. The amount depends on age, sex, interest rates at the time of purchase and the options chosen. Those options are expensive: inflation indexing, a minimum payment guarantee or a survivor benefit all reduce the initial amount, sometimes by a quarter, which makes comparing quotes tricky when the options differ.
Measure the liquidity given up
Capital paid to the insurer stops being available: it no longer serves for a medical emergency, a renovation, help to a child, and it is no longer part of the estate absent a guarantee option. That loss of flexibility is the guarantee's real price, and it is measured concretely: what proportion of your total wealth would be locked up? Converting all of one's savings into an annuity is rarely defensible; converting a portion, while keeping accessible capital for the unexpected, is a decision of an entirely different nature. A portion, not the whole.
Compare with a portfolio drawdown
The alternative is keeping the capital invested and withdrawing an amount each year. That approach preserves liquidity, the possibility of leaving an inheritance and growth potential, at the price of two risks the annuity eliminates: market risk, particularly dangerous in the first drawdown years, and the risk of living longer than planned. A prudent withdrawal rate, revised against actual returns, manages the first; nothing in the portfolio genuinely manages the second, which is exactly the annuity's function.
Combine rather than choose
Practitioners most often land on neither one nor the other: it covers essential expenses — housing, food, utilities — with income guaranteed for life, public pensions plus a life annuity purchased to fill the gap, then lets the portfolio fund discretionary spending, travel, leisure, help to children. That structure removes the risk of lacking necessities while preserving flexibility on the rest. The calculation starts from the essential expense budget, a figure that determines how much annuity to buy, rather than the other way around. Nothing forces that purchase to happen all at once either: buying in tranches over several years spreads the exposure to whatever interest rates happen to be on any single day. Quotes expire quickly, so each tranche is priced fresh.
Quebec scenario: compare before confirming
Facing his $480,000 in retirement savings, a former foreman in Alma receives two irreconcilable pitches: the annuity representative promises the peace of a cheque for life, his broker praises the flexibility of a drawdown portfolio. Rather than joining a camp, he lays both offers on the table and measures them with the same ruler. The life annuity first: $120,000 buys about $680 a month guaranteed for life, whatever the markets and his longevity; in exchange, that capital ceases to exist — illiquid for emergencies, absent from the estate except through a guarantee option paid for in reduced income. The portfolio next: the remaining $360,000 produces adjustable withdrawals, accessible at any time, transferable, but subject to the market and to temptation, a bad sequence of returns early in retirement able to erode what no guarantee protects. His decision grid grows from his expenses rather than the products: $3,100 in essential needs per month, of which $2,400 is already covered by public plans and a small employer pension. The life annuity receives precisely the mandate of closing the essential gap, $700, nothing more; the portfolio keeps the rest — projects, surprises and inheritance. Both salesmen leave with half a point each, and he with a guaranteed floor under a flexible upper storey: the combination neither pitch had offered.

- Calculate the essential gap to fill
- Give the annuity that precise mandate only
- Keep the rest in a flexible portfolio
- Compare annuities from several insurers
- Weigh the guarantee options and their cost
- Protect the portfolio from sequence risk
- Document the floor and the upper storey on file
Frequently asked questions
What does a life annuity promise, and what does the promise cost?
Guaranteed income for life, indifferent to markets and your longevity: the risk moves to the insurer. The price: the capital ceases to exist — illiquid for emergencies, absent from the estate except through a guarantee option paid for in reduced income. The promise is bought by surrendering flexibility.
Which risks does a drawdown portfolio keep?
Market risk — particularly the sequence of returns early in retirement — and behavioural risk: overly generous withdrawals or panicked sales. In exchange: full liquidity, adjustable withdrawals and transferable capital. The two formulas trade different risks for different freedoms.
How are the two combined intelligently?
Through expenses: calculate the gap between your essential needs and your existing guaranteed income — public plans and employer pensions — then give the life annuity the precise mandate of closing that gap, nothing more. The portfolio keeps the rest: projects, surprises, estate.
