The last barn I was at had a late fee. I had to pay it once.
Board was due on the 1st, but wasn't considered late until the 5th (due to people's varying pay dates at work*). After the 5th it was a $15 fee, and after the 15th it was a $5/day fee. Board was $200/month, if that matters.
*I was very happy to hear this, as the job I had at the time payed every second Friday. Sometimes that second payment was on the 3rd, and I couldn't pay my board until then.
