Promposals now make up over a third of the total cost of prom, according to Visa, which sponsored the survey. According to data gleaned from 3,041 phone interviews, the average teen’s family will spend $919 on prom-related expenses this year.

“Prom is a fun night for kids to get together and dance, but spending $300 plus on a promposal to simply ask your date is exorbitant,” Nat Sillin, Visa’s head of U.S. financial education, said in a statement.

The poorest families plan to spend the most on prom, and Northeastern teens are to spend more than teens from other regions, the report states.
