Some Americans spend a lot on weddings — sometimes more than their annual salaries.

According to The Knot 2018 Real Weddings Study, a survey of 14,000 brides and grooms, the average American wedding costs $33,931, the same average as the 2017 survey.

However, the most expensive locale for a wedding, New York City, costs $96,910 on average, up from $76,944 in 2017. For reference, the national mean household income is $84,525 a year.

The Knot also found the average guest count (136), average wedding gown price ($1,631), and the average age of brides and grooms (29.1 and 30.5, respectively). The most popular month to get engaged is December (16%), while the most popular month to get married is September (18%).

For the first time, the Knot surveyed Generation Z (age 14 to 23) newlyweds, who aren't as drawn to wedding traditions as past generations. Some wedding traditions are becoming less common, like the bouquet toss (45% in 2018, down from 53% in 2016) or the garter toss (33%, down from 41% in 2016).

Wedding prices are higher than ever, and often they come close to or exceed average annual salaries.
