Weddings can be a significant financial strain on guests, particularly those in their late 20s and 30s, an age often referred to as the "wedding age." Guests face expenses such as astronomical airfare, hotel accommodations, and wedding gifts, sometimes purchased on credit. For instance, one individual reported spending $3,000 on wedding-related costs in a single year, not for their own wedding, but as a guest. Inflation has also contributed to rising wedding costs for couples.

Couples often underestimate the true cost of weddings, leading to overspending. The average cost of a wedding in 2023 was $30,000, a $2,000 increase from the previous year, with some states seeing averages over $50,000. Underestimating expenses can result in couples going into debt, with one couple accumulating $44,000 in credit card debt for their wedding and honeymoon. Financial advisors suggest setting a clear budget early in the planning process to avoid such pitfalls.

Financial experts advise against taking out personal loans or carrying credit card balances for wedding expenses due to high interest rates, which can exceed 12% on average. Instead, they recommend exploring payment plans with vendors. A common budgeting strategy involves calculating total available funds from family contributions, existing savings, and future savings. To manage guest list size, one method is to divide the total budget by an estimated per-person cost, such as $200 per guest, to determine an affordable number of attendees.
