You can charge pop-up shop vendors however you'd like, but it's common to charge an hourly fee based on the size of the pop-up venue, which often ranges anywhere between $50 to $200 per hour. Some pop-up hosts also charge a small daily reservation fee. Ideally, you should look for a fair rate that generates enough income to be worth your while but is affordable enough that your pop-up vendors can still turn a decent profit—this will keep them coming back.
