The More You Spend on the Wedding, the Higher the Divorce Rate — and the Cheapest Couples Are the Most Stable
Research shows lower wedding spending tracks with lower divorce rates, with the lowest rates among couples who spent under $1,000; and the more a man spends on an engagement ring, the higher his divorce risk.

Being a tightwad isn't saving money, it's feeling pain when you spend
The 2008 paper splits spending tendencies into tightwad and spendthrift poles, and the core variable is the "anticipatory pain of paying" — the immediate emotional reaction at the moment of purchase, not a rational calculation about the future. A tightwad feels too much pain when spending and spends less than he or she ideally would; a spendthrift feels too little and spends more than ideally. The key distinction: a frugal person derives pleasure from saving, while a tightwad suffers pain from spending. So the scale doesn't measure how much you spend but the gap between your actual behavior and your ideal self — you can be wealthy and a tightwad, or nearly bankrupt and a spendthrift.
— Benjamin FelixTightwads and spendthrifts are more likely to marry each other
Research shows tightwads are more likely to marry spendthrifts than their own kind. The authors' explanation: people have poor introspective ability about what will attract them in a real partner; when the other person displays the same spending flaw as you, it reminds you of that negative trait in yourself, so "fatal fiscal attractions" happen — someone who doesn't share your flaw is actually less attractive at first. But the excitement is short-lived: cross-pole couples report more frequent money conflicts and lower marital happiness, and the wider the gap between the two on the scale, the more likely conflict becomes. This holds after controlling for household debt and savings.
— Benjamin FelixNobody talks about prenups because of two mechanisms
First, optimism bias: one study found engaged couples could accurately estimate the national divorce rate but estimated their own odds of divorce far below it. That creates real risk — they may sign an agreement without seriously considering the divorce scenario the agreement was designed to govern. Second, signaling cost: law-and-economics research argues that merely raising the topic of a prenup is itself a negative signal of insufficient commitment to the relationship, so partners are reluctant to bring it up first. The two mechanisms together produce severe underuse of prenups, and even when one exists it may be hastily designed.
— Benjamin FelixThe more you spend on the wedding, the higher the divorce risk
The 2021 Journal of Consumer Policy paper, using survey data from more than 3,000 married respondents, found the opposite of intuition after controlling for income, demographics and other relationship factors: the more spent on an engagement ring, the higher the man's divorce risk; the more spent on the wedding, the higher the woman's divorce risk. Wedding-related debt stress is one possible mechanism. The couples with the lowest divorce rates spent under $1,000 on the wedding. But the same study has two counterintuitive positive findings: more guests, and taking a honeymoon (regardless of price), both predict longer marriages.
— Benjamin FelixThinking of money as joint matters more than merging accounts
A 2022 analysis spanning six studies and more than 38,000 participants found that couples who fully merged their finances had higher relationship satisfaction and were less likely to break up, and this held across cultures. A 2023 Journal of Consumer Research study found joint accounts promote communal norms, shared goals and a better sense of team money management. But Johanna Peets' 2025 paper "Talk About Shared Money" points out that the benefits of merging may not come from actually merging accounts — merely directing attention to an existing joint account rather than to separate individual accounts produces similar effects. In other words, thinking of finances as "ours" rather than "mine and yours" is the step that does the work.
— Benjamin FelixFinancial infidelity hurts a relationship more than mismatched spending views
Financial infidelity is defined as engaging in financial behavior you expect your partner would object to and hiding it. A recent paper found that when one partner is more inclined to do this than the other, such mismatched couples are more likely to drift toward separate financial goals, predicting lower financial well-being and relationship satisfaction. This holds after controlling for other partner mismatches (say, one tightwad and one spendthrift). Sticking to joint accounts only makes hiding large expenditures harder, but Benjamin argues it won't stop someone who really wants to hide — they'll either open another account or detonate the problem early, which is no longer something financial planning can solve.
— Benjamin FelixIn household asset allocation, the husband's risk preference carries more weight
A 2026 Review of Financial Studies paper shows Australian households on average incorporate only 40% of the wife's risk preference into household asset allocation versus 60% of the husband's, which the authors call a 20-percentage-point bargaining gap; half is explained by observable characteristics such as income and employment, and the other half is attributed to a gender effect. The husband's average bargaining weight is 69% in Germany and 60.1% in the US — statistically indistinguishable across the three countries, but all above 60%. The 2021 Journal of Finance paper "Who Wears the Pants" found that US households where the husband has high financial literacy are more likely to participate in the stock market than households where the wife has equal literacy, which the authors argue is better explained by gender identity norms than by ability differences.
— Benjamin FelixThe biggest risk is that the partner who manages the money dies first
If one partner handles all financial decisions and the other is completely in the dark, then if the primary money manager dies or suffers cognitive decline, the survivor will have a very hard time taking over. Benjamin says they have many clients who come to them very late in life, often because the partner who always managed the money worries that the other won't be able to cope independently after they're gone — and "the sharks will start circling": the banks will call. He also mentions a paper from a few years ago showing that undetected cognitive decline leads to poor financial decisions, so some people treat hiring an advisor as a hedge against that.
— Benjamin FelixIn their own words · checked verbatim
A tightwad is not someone who doesn't get a lot of pleasure from spending. It's someone who deep down wishes they could get more pleasure from spending than they're actually getting.
Benjamin Felix0:00
Frugal is deriving pleasure from saving. Being a tight wad is incurring pain from spending.
Benjamin Felix7:21
when tightwads and spendthrift encounter similar behaviors to their own in others, it reminds them of that negative behavior quality in themselves
Benjamin Felix19:46
Couples who experienced the lowest divorce rates spent less than $1,000 on their wedding
Benjamin Felix34:19
Simply redirecting people's attention toward their existing joint accounts rather than their separate ones was enough to produce a similar effect.
Benjamin Felix40:32
Female identity suppresses the wife's willingness to contribute ideas, while male identity makes husbands less receptive to a spouse's input.
Benjamin Felix50:56
the couples who are going to set themselves up the best financially and emotionally are the ones who approach finances of marriage as a team and have open communication
