Bill Perkins published "Die With Zero" in 2020 and proposed something that sounds reckless but isn't: that dying with a large amount of unspent money is a mistake. Not a minor inefficiency — a mistake. The argument is that every dollar left unspent at death is a dollar that generated zero life experience, zero memory, zero value for you or anyone else. You worked for it. You saved it. And then it sat there while opportunities to use it expired.

The book's central claim is that you should optimize not for wealth accumulation but for life experience — and more specifically, for the timing of those experiences to match your capacity to enjoy them. A dollar spent at 35 on a physical adventure with your children creates a memory that compounds in the form of stories, photographs, relationships, and identity. The same dollar spent at 80, if you're still alive and healthy enough to spend it at all, has a fraction of that experiential return. Time, health, and money are three different currencies, and they're not interchangeable. The Die With Zero argument is that most people with financial resources systematically misallocate because they treat money as the scarce resource when, past a certain threshold, health and time are actually the binding constraints.

This has direct implications for how you think about spending in retirement. The conventional model — spend conservatively early in retirement to preserve assets, hoping to avoid running out — is defensible as a risk management strategy but comes with a real cost: it produces systematic underspending during the healthiest and most capable years of retirement. Perkins calls this the "declining marginal utility" problem. The 62-year-old who wants to travel but is afraid to spend is foreclosing experiences that will literally become physically impossible at 75. The rational response is not to recklessly spend down everything immediately, but to match spending to experience potential, which is highest when you are youngest and healthiest.

There is a memory dividend concept in the book worth understanding. Perkins argues that experiences produce not just immediate pleasure but a stream of future psychological returns — the memory dividend. Research in positive psychology supports this: experiential purchases consistently produce higher and more durable happiness than material purchases, partly because experiences integrate into your self-narrative, become conversational currency with others, and are not subject to the hedonic adaptation that flattens the pleasure of owning things. A memorable trip creates a memory you return to for decades. A car becomes baseline within months. This is not new-age sentiment; it is a predictable feature of how human memory and adaptation work.

The book also addresses children directly. Perkins does not argue against giving to your children — he argues for giving earlier rather than later. When a parent dies at 80 and leaves an inheritance to adult children who are now 55, the children receive money at the stage of life when they are often already financially established, mortgage-paid, and past the years when money had maximum leverage. The same money given at 25 or 30 could have funded a down payment, cleared student debt, or seeded a business — actions with compounding consequences over the following decades. Perkins calls this the "peak giving years" concept: there is an optimal window to transfer resources to children, and it is usually decades before the traditional inheritance moment.

The hardest part of Die With Zero for most people to accept is psychological rather than mathematical. The safety of a large account balance is deeply comforting. Spending it down — even rationally, even deliberately — triggers anxiety about the future that is disproportionate to the actual risk. This is loss aversion operating on retirement assets. Perkins's answer is annuitization: converting enough of your assets into guaranteed income streams to cover basic living costs, freeing the remainder for intentional spending without existential terror. If $4,000 per month in Social Security and annuity payments covers your floor, you can spend your discretionary assets on experiences without the fear that you'll end up destitute.

Several critiques of Die With Zero are worth engaging. The book primarily speaks to people with substantial assets — it is less immediately applicable to retirees living near the financial edge, for whom precautionary saving is rational rather than neurotic. Health is unpredictable in ways that make aggressive early spending risky: a person who spends freely at 65 in anticipation of declining health may face large unexpected medical expenses at 78. And the experience-optimization framing can be captured by consumer marketing in ways that produce guilt-driven spending on expensive vacations rather than the genuine meaning-oriented investment Perkins intends.

Despite these limitations, the core insight is durable: the purpose of money is to fund a life, not to accumulate as its own end. If you finish life with significantly more money than you needed, you either worked more than you needed to, experienced less than you could have, or gave less than you intended. Die With Zero is a challenge to examine which of those is true for you — and to do something about it while the clock is still running.
