This year's incoming class of MBA students at Harvard Business School will face an annual sticker price on the tuition of a whopping $73,440; 18 years ago, annual tuition was just $30,050. But average scholarship grants — given to roughly half the students — have grown, too. In 2002, the average annual grant was roughly a third of the tuition at $9,001. Today, it's more than half, at $42,000.
