According to The Knot, the average cost of a wedding in 2021 was $28,000. Let’s say a small wedding will cost a quarter of that amount. You’re still looking at around $7,000 for the event, unless, of course, you cut out a lot of the traditional expenses. There’s no set-in-stone number for how much a small wedding would cost, but a lower guest count will ultimately be more budget-friendly and save you money.
