Some people go a little overboard when it comes to planning their dream weddings and end up spending an unbelievable amount of money. Now, however, a study has revealed that having an expensive wedding may not be such a good idea.

Carried out by economic professors Andrew Francis-Tan and Hugo M. Mialon, the study found that certain characteristics that will increase the chance couples will end up divorced. After surveying 3,000 married people, the professors learned that the price of the engagement ring and the overall cost of the wedding plays a significant role in how long a marriage lasts.

“Specifically, in the sample of men, spending between $2,000 and $4,000 on an engagement ring is associated with 1.3 times greater hazard of divorce as compared to spending between $500 and $2,000,” the study stated.

The study found that if a ceremony costs less than $1,000, there will be a huge decrease in the probability a couple will end their relationship, while if a wedding cost more than $20,000, the likelihood they’ll separate will be 1.6 times higher.

They also found that the cost of a couple’s honeymoon did not play a role in their marriage direction and is “significantly associated with a lower hazard of divorce.” On top of that, physical attraction to their spouse also plays a huge factor in how long a couple will stay together.

“Reporting that one’s partner’s looks were important in the decision to marry is significantly associated with shorter marriage duration,” Mialon explained.

Another study found that love, similar backgrounds or interests, and friendship were the secrets to a long lasting marriage. Another major factor is a couple sharing an understanding of what their union means to them.

“A long-term and satisfying marriage is not merely a matter of finding someone who can make you happy,” the authors concluded. “It is a matter of two people who have a shared understanding of what their marriage means for them.”
