Student loans are a large problem, and it's hard for an 18 year old to make a decision about whether they're the right decision. Lots of websites say "all student loans are bad", and lots of websites say "student loans are good no matter what". But no websites give a measured picture of what life looks like after taking student loans.
This website is a simple calculator: you enter your major and the type of school you're planning to attend. The website uses data collected by the federal government College Scorecard (https://collegescorecard.ed.gov/) to give an estimate of your expected income and how much of it will go to loans.
