Parents, if your kids' college bills didn't send you into a financial tailspin, better watch out for the wedding budget. In some of the priciest markets, the cost is as bad as paying for an extra year of college — or worse.

Couples married in 2016 shelled out an average $35,329 to cover wedding costs, according to The Knot's annual survey. That's a record high in the survey's 10-year history, and up from an average $32,641 in 2015.
