As for the net cost for attending SDSU, the actual amount depends on the annual family income of the candidate. The net price is nothing but the actual amount that a student is required to pay in a year. Generally, the higher the family income of the candidate, the higher is the net amount to be paid. So, it all essentially depends on the family income bracket of the student. At SDSU, the average net price is estimated to be around $18,195. For students with a family income below $30,000, the estimated net price is $15,285, while for the individuals who fall in the $30,001-$48,000 income bracket, the net cost is $16,273.
