You’re correct, but even the median (with inflation) is still probably over $20,000 right now (based on the assumptions that it was $18,000 in 2019 and 2020 is not representative). I think my broader point still stands.
I know a person currently planning a relatively small wedding, and she’s trying very hard to save money. One cost-cutting measure was booking a space on the fourth floor of a building without an elevator. (She asked me whether or not it would be possible for strong guests to carry elderly guests up the stairs.) Her budget is still $10,000.
