The Price of Forever
The American wedding industry operates on an unexamined premise: spending more reflects loving more. A better venue signals a better partnership. A bigger diamond proves deeper commitment. The average U.S. wedding now costs roughly $35,000, and couples routinely go into debt to reach that figure, because the alternative feels like an admission that the relationship isn't worth the investment.
Two economists at Emory University decided to check whether the investment pays off.
What 3,151 Marriages Revealed
Andrew Francis-Tan and Hugo Mialon surveyed 3,151 ever-married adults in the United States, collecting data on wedding ceremony costs, engagement ring spending, and current marital status. They controlled for household income, education, age at marriage, race, religious attendance, employment, relationship duration before the wedding, and how the couple met (Francis-Tan & Mialon, 2015).
The relationship between spending and marriage duration was negative.
Couples who spent more than $20,000 on their wedding were 3.5 times more likely to have divorced than those who spent between $5,000 and $10,000. Those who kept the ceremony under $1,000 had the lowest divorce rates in the entire sample, 53 percent below average. Engagement ring spending followed the same pattern: men who spent $2,000 to $4,000 on a ring were 1.3 times more likely to divorce than those who spent $500 to $2,000.
But one finding reversed the obvious interpretation that smaller is simply better. Couples who invited 200 or more guests were 57 percent less likely to divorce than couples with 10 or fewer attendees. The signal was not about austerity. It was about community.
People, Not Price
The split between spending and attendance is the study's most revealing result. Expensive weddings predicted shorter marriages. Large guest lists predicted longer ones. The researchers distilled their overall finding into one sentence: "The types of weddings associated with lower likelihood of divorce are those that are relatively inexpensive but are high in attendance."
Francis-Tan and Mialon proposed two mechanisms. First, wedding debt creates early financial stress. Within their own sample, couples who reported feeling stressed about wedding-related debt were significantly more likely to have divorced. Financial conflict ranks among the strongest predictors of marital dissolution across decades of family research (Dew, Britt & Huston, 2012), and a ceremony that pushes a couple into the red may serve as the marriage's first serious financial fight.
Second, a large guest count signals an established support network. A wedding with 200 attendees requires coordination among extended families, friend groups, coworkers, and neighbors. That network does not dissolve after the reception. When the marriage hits its inevitable rough stretch, the couple with 200 witnesses may have a deeper bench of people invested in keeping them together.
The Strongest Case Against This
The most serious objection is selection bias. Couples drawn to extravagant weddings may differ from those who prefer simpler ceremonies in ways the study's controls cannot fully capture. Perhaps people who prioritize lavish displays are more materialistic, more focused on the wedding as performance rather than partnership, or more susceptible to social comparison. If that is true, the spending is a symptom, not a cause. A frugal version of the same couple might divorce at exactly the same rate.
This criticism has genuine force. The data came from a Mechanical Turk survey, which is adequate for detecting correlations but cannot achieve the internal validity of a randomized experiment. You cannot randomly assign couples to spend $5,000 or $50,000 and observe what happens. The causal chain remains inferential.
Francis-Tan and Mialon acknowledged this directly: their findings are associational and "should not be interpreted as causal."
What We Didn't Prove
This study cannot determine whether cutting your wedding budget would improve your marriage. The negative association between spending and duration may be driven entirely by unmeasured characteristics of high-spending couples.
The sample, while large at 3,151, was recruited through Amazon Mechanical Turk in 2014 and skews younger, more educated, and more internet-savvy than the general U.S. population. The findings may not generalize to different cultural, economic, or generational contexts.
Wedding costs and marital status were self-reported retrospectively. Divorced respondents may recall their wedding expenses differently from those who remained married. And no independent replication of this specific study has been published, though the broader pattern linking large guest counts to better marital outcomes appears in related work from the National Marriage Project and the Institute for Family Studies.
The Bottom Line
In a sample of 3,151 American marriages, the $50 billion wedding industry's core promise did not hold up. More money on the ceremony predicted shorter marriages. The only variable that tracked with marital durability was whether the couple invested in having people present, not in having things.
A wedding is, at its core, a public commitment made before a community. The industry has reframed it as a consumer experience with a price-quality relationship. This study suggests that framing is backward. The value is in the room, not in the décor.
What You Can Do
Redirect spending toward headcount. If you are planning a wedding, consider reallocating money from production costs (the venue upgrade, the photography package, the floral arrangements) toward including more people. A backyard reception with 200 guests may outperform a ballroom dinner for 50.
Check whether your budget is creating debt. Couples in this study who reported wedding-related financial stress divorced at higher rates. If the ceremony requires borrowing, the research suggests that is a risk factor worth taking seriously.
Go on the honeymoon. One additional finding in the data: couples who took a honeymoon were 41 percent less likely to divorce than those who skipped it. If a trade-off is necessary, the evidence favors spending on the trip together over spending on the party itself.
If you already had an expensive wedding, relax. A population-level correlation across 3,151 people cannot predict any individual outcome. Your marriage is shaped by factors that no survey captures.
