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%.
A good return on investment is 15% annually. That's healthy. That's reasonable. (It's aggressive, but it's achievable if you put in time to look for bargains.) You can double your money every six years with 12% after taxes and inflation. More importantly, you can beat the market.
