What is the typical deposit needed to secure a spot after an acceptance? 10% of Tuition on April 10?
5K which is nonrefundable.
@PhotographerMom What if you get full FA? Sorry if this is hijacking.
@mathman, in our case all the schools basically asked for 10% of what our share of the tuition would be (after deducting the FA award).
The non-refundable part applies across the board AFAIK. The actual dollar amount will vary by school, but it’s roughly 10%.
Well… Andover and Exeter tuition is ( barely ) under 50K but most boarding schools are 50K+ .
5K is a safe number for planning purposes. 
Deposit is 20% for Cate
Ours was a bit over ten percent, closer to twenty.
