Retirement is more than a withdrawal rate: reading Christine Benz's How to Retire

For people who have saved all their lives, the hardest thing to do in retirement may be to start spending.

That is an observation Christine Benz made on an episode of The White Coat Investor podcast broadcast on 15 January 2026: many retirees, after years of saving, find it hard to start drawing on their savings, and often anchor on the high their portfolio once reached. The remark comes from an interview and does not necessarily match any one chapter of the book, but it is a good way into her How to Retire.

Twenty experts, one lesson each

How to Retire is published by Harriman House. The paperback runs to 336 pages, was published on 17 September 2024 and has the ISBN 9781804090695 (publisher's book page, checked in October 2026). According to the Investments & Wealth Institute's review page, the book's subtitle is "20 Lessons for a Happy, Successful, and Wealthy Retirement".

The structure is simple. According to the publisher's page, Benz asked twenty retirement thought leaders to each share one lesson they believe leads to a successful retirement. She added in the podcast that the book has twenty chapters, each a conversation between her and one expert on one topic.

The publisher's page names only three of them: William Bernstein, Ramit Sethi and Laura Carstensen. The other seventeen are not listed on that page.

The topics go beyond numbers

The range of topics is wide. The publisher's page lists them as finding your retirement income style, how spending may change and how to organise a portfolio around it, spending to optimise happiness, and living with no regrets.

On the podcast, Benz split the content into two groups: financial topics such as asset allocation and how much to spend each year, and non-financial topics such as where to live, healthcare and how to keep up social connections.

Third parties read the book in a similar way. The Retirement Management Journal, published by the Investments & Wealth Institute, ran a review of the book in volume 14, issue 1 (2025). Its public summary says the book deals with both the financial and the personal side, including investments, benefits and spending, and is built around the relationship between time and money, covering goal setting and what a fulfilling retirement looks like. When the University of Chicago's Lead for Society featured a video interview with Benz on 8 November 2024, it also noted that the conversation covers non-financial lessons, including the value of relationships and how to live without regrets.

In other words, the book asks not only whether the money is enough, but what the money is meant to buy.

3.9% is a starting point, not the answer

The withdrawal rate still has a part to play. Discussing Morningstar's research in the same podcast episode, Benz said the base-case withdrawal rate is 3.9% (for someone retiring around the start of 2026), which gives a 90% probability of not running out of money over 30 years. She described it as a conservative starting point with fixed-amount withdrawals, did not recommend following it mechanically, and said she herself prefers flexible spending that adjusts to circumstances.

Note that this is a discussion of Morningstar's research on the podcast, not a chapter of the book, and the figures rest on particular market conditions and assumptions.

Why saving enough still does not make spending easy

Back to the opening puzzle. On the podcast, Benz said this psychological hurdle is especially common among more affluent retirees, and explained it through mental accounting: people feel more comfortable spending income that resembles a salary, such as Social Security, annuity payments and dividends, than selling investments. The same sum of money feels completely different to spend depending on where it comes from.

If your retirement cash flow relies mainly on selling investments, this hurdle is worth recognising early, rather than discovering in your first year of retirement that you cannot bring yourself to spend.

She also divides people into "maximisers" and "satisficers": the former chase the perfect plan, while the latter accept a reasonable plan and move on.

How much is enough?

Public information does not show that the book has a chapter defining "how much is enough", so this should not be taken as a claim of the book. Still, the satisficer's way of thinking is itself an answer: enough is not a figure worked out to the last decimal place, but a point at which you are willing to stop optimising and start living. This is this article's interpretation, not the author's words.

Long-term care: worth a separate budget

In the same podcast episode, while discussing Morningstar's research, Benz treated the cost of long-term care in later life as one of the main risks in retirement. She suggested planning for it separately, through insurance or a dedicated pot of money kept apart from the assets available for everyday spending, and mentioned that home equity can also be used to pay for care.

This too comes from the podcast. The public information available cannot confirm whether the book has a chapter on long-term care or on tax, so readers who want to look into either should turn to specialist sources.

How to read the book

Since each chapter is one expert and one topic, the book need not be read from cover to cover. You may get more from it by choosing the few chapters closest to your own situation, such as how spending changes and spending for happiness, and then going back to the portfolio sections.

When you have finished, try something harder than calculating a withdrawal rate: write down three things you would spend money on to buy back time, and then actually do them.
