Excerpt: Frugality is celebrated as financial virtue. But chronic underspending carries its own kind of ruin — one nobody talks about.

The personal finance industrial complex has spent decades drilling a single commandment into the public consciousness: spend less, save more. It has produced a culture that fetishizes frugality — where skipping the $6 latte is treated as wisdom, where patching the leaking roof "next season" feels like discipline, and where the person with the fattest savings account is presumed to be the most financially sophisticated person in the room.

What this narrative quietly ignores is a category of financial damage that doesn't show up on a balance sheet, at least not right away. Chronic underspending — the habitual refusal to part with money even when doing so would clearly improve one's circumstances — is a recognized pattern in financial psychology, and its long-term costs can rival those of chronic overspending. The math just works more slowly, and the harm is much easier to mistake for virtue.

The problem isn't saving. Saving is essential. The problem is when the refusal to spend becomes reflexive, anxiety-driven, and ultimately self-defeating. That distinction matters more than most people realize.

The Pain That Won't Spend

In 2008, behavioral economists Scott Rick, Cynthia Cryder, and George Loewenstein published a landmark study in the Journal of Consumer Research that introduced formal vocabulary for something many people had felt intuitively. Their research identified two distinct psychological types: "spendthrifts," who experience too little discomfort when parting with money and thus tend to overspend, and "tightwads," who experience an outsized, anticipatory pain at the very thought of spending — and who, as a result, consistently spend less than they themselves would ideally want to.

The finding that challenged conventional assumptions: in a survey of more than 13,000 people, tightwads outnumbered spendthrifts by a ratio of roughly three to two. Chronic underspending, it turns out, is far more common than chronic overspending — it's just culturally invisible because it looks like responsibility.

What makes the tightwad pattern distinct from ordinary thrift is that it isn't rational. Truly frugal people make deliberate tradeoffs — they forgo a vacation to fund a retirement account or choose a cheaper cut of meat to pay down debt. Tightwads, by contrast, experience the pain of spending regardless of what is being purchased or whether they can clearly afford it. The discomfort precedes any cost-benefit analysis. The wallet stays closed before the reasoning even starts.

Dr. Brad Klontz, a financial psychologist and coauthor of Mind Over Money, has studied similar patterns under the umbrella of what he calls "money scripts" — unconscious beliefs about money formed in childhood and carried, largely unexamined, into adult financial life. Among the scripts he identified, "money avoidance" describes people who associate money with anxiety, guilt, or moral danger, and who as a result may avoid spending even on reasonable or necessary purchases. These individuals often come from households that experienced financial trauma — job loss, bankruptcy, a parent who stressed constantly about bills — and have internalized the message that spending is, in some fundamental sense, dangerous.

The problem, Klontz has noted, is that money vigilance taken to extremes stops being a virtue and starts being a liability. "Severe under spenders neglect basic self care," he has observed. "They don't go to the dentist or doctor because they don't want to spend the money."

What Underspending Actually Costs

Here is where the frugality narrative runs into arithmetic.

The most immediate category of financial damage from chronic underspending is deferred maintenance — the slow accumulation of small problems that compound into large ones because the cost of prevention felt too high. A 2025 study found that the average deferred home repair now costs more than $5,600 to complete, and that homeowners who skip routine maintenance face repair costs three to five times higher than the cost of the preventive care they avoided. A $200 roof patch left unaddressed for a season can become a $20,000 roof replacement. A $150 gutter cleaning skipped annually can produce foundation water damage costing tens of thousands of dollars. The money that felt like it was being saved had simply been lent to the future at a punishing interest rate.

The same dynamic plays out in healthcare, at higher stakes. Recent survey data found that over a third of insured American adults have skipped or delayed medical care in the past year due to cost concerns — not because they lacked coverage, but because the out-of-pocket perception was enough to deter them. The downstream consequences are well-documented. Conditions identified at later stages require more intensive treatment, carry poorer long-term outcomes, and cost substantially more to manage. A cholesterol screening avoided for three years doesn't save the cost of the screening; it potentially converts a manageable condition into a cardiac event. The financial prudence that felt like discipline becomes, in retrospect, the most expensive decision a person made.

Career and professional development represent a third zone where underspending quietly extracts long-term cost. The refusal to invest in a professional wardrobe, a relevant certification, a conference attendance, or a coaching relationship may feel like financial conservatism. Over a 30-year work life, the compounding effect of underfunded professional presence and underdeveloped skills can translate into millions of dollars in forgone earnings — a cost that never appears on any budget spreadsheet because the counterfactual is invisible.

And then there are the relationship costs, which are harder to quantify but no less real. Research from Scott Rick's ongoing work on tightwad behavior has found that chronic under spenders are often a source of significant friction in their partnerships. They miss birthdays with underwhelming gifts. They resist the family vacation that their partner and children want. They propose the cheapest option at every decision point, regardless of the occasion. Over time, this pattern communicates something to the people around them — that comfort, pleasure, and celebration are not worth paying for — and that message erodes relationships in ways that no savings account can compensate for.

The Scarcity Mindset That Outlasts Scarcity

Perhaps the most insidious dimension of chronic underspending is that it frequently persists long after the financial conditions that produced it have changed.

Financial therapists describe this as a "scarcity mindset" that becomes structurally embedded — a cognitive framework forged in genuine hardship that continues operating as if nothing has changed, even after income has risen, debts have been paid, and savings have grown comfortable. The neuroscience here is instructive: the emotional systems that respond to financial threat don't automatically recalibrate when circumstances improve. They require deliberate, conscious intervention to reset.

This is why a person who grew up in a household that struggled through a serious recession may still, decades later, lie awake doing the math on a $40 dinner with friends. It explains why retirees with ample savings frequently report being unable to spend their nest eggs, even when their financial planners have confirmed, repeatedly, that the numbers support it. A Kitces.com analysis of behavioral finance research published in late 2025 described this as one of the most common and under addressed challenges in financial planning: clients who have successfully accumulated wealth but cannot psychologically access it. The saving reflex, once installed, doesn't have an off switch.

This is also, notably, not a condition that self-resolves through wealth accumulation. Higher income does not cure tightwaddism; research by Rick and colleagues found little relationship between income levels and tightwad-spendthrift scores. Some of the most documented under spenders are high earners — professionals making substantial salaries who still delay medical appointments, wear shoes past the point of comfort, and refuse to turn on the heat in winter.

The Opportunity Cost Nobody Calculates

There is a subtler category of cost that rarely enters the personal finance conversation: the cost of unlived experience.

The research on spending and well-being is reasonably consistent. Experiential spending — money directed toward travel, meals, learning, time with people you care about — tends to generate more lasting satisfaction than material acquisition. The decision to delay or forgo these experiences in favor of a larger savings balance is not cost-free. It is a choice to trade present quality of life for a future that is, by definition, uncertain.

Behavioral economist Shlomo Benartzi has written extensively on the tendency to overweight future financial security while discounting present experience — what he describes as an asymmetry between how we plan and how we actually live. The retiree who spent forty years skipping vacations to fund a retirement account and then finds themselves, at seventy-two, physically unable to travel, has not made a financially rational decision. They have made an emotionally driven one, dressed in the language of rationality.

This is not an argument against saving, or for spending recklessly. It is an argument for precision. A $6,000 emergency fund is prudent. A $600,000 cash balance accumulated through decades of anxiety-driven withholding, while forgoing medical care, career investment, and meaningful experiences, is something else entirely — and the financial therapy field now has a name for it.

Rebalancing the Conversation

The cultural bias toward frugality as virtue is not entirely misguided. Overspending has real, well-documented consequences. The instinct to save, to resist impulse purchases, to build a cushion — these are legitimate goods. The problem is the absence of a parallel cultural conversation about the costs of the opposite failure mode.

Financial literacy, as it is currently taught and discussed, focuses almost entirely on the dangers of spending too much. It rarely acknowledges that spending too little — in specific, deliberate, well-chosen ways — is also a financial skill, and that the failure to develop it carries compounding costs of its own.

A genuinely healthy relationship with money isn't defined by the size of the balance or the restraint of the spending. It's defined by the ability to deploy money intentionally: to invest it where it generates returns, to spend it where it generates quality of life, and to save it where it provides security. The person who can do all three is not the most frugal person in the room. They are the most financially capable one.

Saving is not the goal. A well-lived life, funded intelligently, is the goal. The bank account is a tool toward that end. When it becomes the end itself — when the number going up is the source of emotional regulation, and spending in any amount triggers anxiety — the tool has started running the person.

That is not discipline. That is its own kind of debt.
