Costs and Financial Aid. The cost of attendance is the total amount of tuition, fees, room and board, books, supplies, and other estimated school expenses. Financial aid is a combination of grants, loans, scholarships, and work-study employment designed to help offset the total cost of attendance.
One of the major problems for an investor looking at that 10% average return figure and mistakenly expecting to realize a nice yearly profit from investing in the S&P 500 is inflation. Adjusted for inflation, the historical average annual return is only around 7%.
Expected Return. The return on an investment as estimated by an asset pricing model. It is calculated by taking the average of the probability distribution of all possible returns. For example, a model might state that an investment has a 10% chance of a 100% return and a 90% chance of a 50% return. The expected return is calculated as: Expected Return = 0.1(1) + 0.9(0.5) = 0.55 = 55%.
