The holiday season—and December, in particular—is the most popular time of year to get engaged. About 16 percent of couples get engaged in December alone, according to TheKnot.com's statistics.
But once the euphoria of the engagement wears off, there's the matter of paying for the wedding. And that's not a small matter. The average cost of a wedding in the United States is expected to be around $26,000 in 2015, according to Shane McMurray, CEO of The Wedding Report, a research company that studies trends in the wedding industry. That's up about $2,000 from 2014.
"Couples will probably spend a little more than they did this year because the economy looks better with more money to spend," McMurray said. "And when people have more money they tend to go a little bit extra" with their wedding expenses.
And in certain parts of the country, that figure can go much higher. For instance, in 2013, couples in the New York City area paid the most to get hitched. Newlyweds in Manhattan paid on average the most in the U.S. at around $87,000, according to The Knot, with Long Island being the second most expensive wedding market at an average cost of $57,343. Outside of New York City metro area, other expensive wedding sites include Chicago, Santa Barbara, California, and Rhode Island
While the sticker price is expected to grow next year, the average guest list is not. The number of guests for a wedding is expected to remain around 135 people on average, in part because more couples are paying for the wedding themselves, McMurray said. As a result, more soon-to-be-newlyweds choose to spend on things that are more personal to them, thus cutting back on the number of people they invite.
And as for the actual number of people getting married? That's expected to remain flat. McMurray said he expects between 2.1 million and 2.2 million people will tie the knot next year, about the same amount as 2014.
Two factors could help increase demand in the wedding industry, though. For starters, same-sex marriage became legal in many more states recently, boosting the number of eligible couples, McMurray said. In the United States, there are an estimated 605,472 same-sex households, of which 168,092 couples are married, according to 2011 American Community Survey from the Census Bureau.
That number is likely to grow in 2015. Currently, same-sex marriage is legal in 35 states and the District of Columbia, but that number could grow to 36 soon. A stay on a court ruling in Florida ends on Jan. 5, and if it's allowed to run out, gay marriages will commence there as well.
Plus, there's a strong chance that the Supreme Court will revisit marriage equality and decide on whether the remaining bans are constitutional. All of this means that many more happy LGBT couples could walk down the aisle next year.
"You'll see an uptick from that because of the demand that's been pent up over the years," McMurray told CNBC. "But that's going to level out in the normal ranges as these couples finally get a chance to get married and start a family."
How people spend their budget may change as well. As the price of oil drops—to a 5 1/2 year lows this week—so does the cost of catering and travel. But McMurray said couples are likely to spend that savings somewhere else, instead of banking it.
"You'll probably see people spending more on the reception and the actual party," McMurray said, adding that some couples may also choose far-away locations for their nuptials if prices remain low. Although, as figures show, decreased oil prices don't always equate to cheap plane tickets.
Of course, McMurray said that couples planning their weddings now shouldn't bank on prices to stay low. To hedge against this, he advised caution in gauging the prices of the parts of a wedding.
