gavra, My impression in the NY area, litvish tuition is about $500/month for parents who can afford that, and somewhere between $250/month (i.e. Kollel) to $450/month for parents who cannot afford the list price. And there are often volume discounts for multiple children in a family. The Chasidish Yeshivas seem to charge about $100/month less than this. (These are my impressions.)
My question to you was how does $400/month = $2k/year? $400/month = $4k/year (for 10 month; $4800 if it is paid over 12 months.)
How much, about, is tuition out of town? And how do the poor cope with it?
