The Finances of Marriage | #426

In this episode, Ben Felix, Dan Bortolotti, and Ben Wilson take a research-driven look at the finances of marriage, from spending personalities and prenuptial agreements to wedding costs, joint accounts, financial infidelity, and household decision-making. The conversation explores how the way couples think about and manage money can affect both financial outcomes and relationship satisfaction.

We unpack the difference between being frugal and being a "tightwad," why tightwads and spendthrifts may be drawn to each other despite having more conflict later, and how simply understanding your partner's spending tendencies can improve financial conversations. We also examine the case for prenups, the role of optimism bias in avoiding them, and how couples can use legal agreements to deliberately design their financial arrangements.

The discussion then turns to wedding spending, including the marketing forces behind engagement-ring conventions and research linking higher spending on rings and weddings with greater divorce risk in some samples. Finally, we look at the evidence for managing money jointly, the risks of financial infidelity, and why both partners should be involved in household financial decisions. The central theme throughout is simple: couples tend to be better served when they approach their finances as a team and communicate openly.
