When 23-year-old Brandon headed from Massachusetts to the Bay Area in mid-May to start work as a software engineer at Google, he opted out of settling into an overpriced San Francisco apartment.
Instead, he moved into a 128-square-foot truck.
'I'm going for a target of saving about 90% of my after-tax income, and throwing that in student loans and investments,' he told Business Insider.
Salary potential isn't the only factor to consider when college searching -- but it's nice to know which schools are paying off in the long run, particularly since tuition continues to soar.
In a new report, the Georgetown University Center on Education and the Workforce looked at the four-year colleges whose students go on to earn the highest salaries 10 years after starting their studies.

'Everyone says they want to be rich, and there's certainly enough advice out there on how to acquire more money,' writes self-made millionaire and best-selling author Steve Siebold.

78 years ago, a journalist who studied 500 millionaires realised something about relationships that is just as relevant today
Nearly a century ago, journalist Napoleon Hill studied more than 500 self-made millionaires over 20 years. His research culminated in the 1937 bestseller 'Think and Grow Rich,' which shares what he calls the 'money-making secret' in 13 principles.
His 10th principle -- 'the mystery of sex transmutation' -- suggests that love, romance, and sex are critical factors in the determination of one's success and wealth.
Mastering your money has a lot more to do with psychology and mindset than we might think.
That's what Napoleon Hill preached in his bestselling 1937 book 'Think and Grow Rich,' the culmination of his intensive study of more than 500 self-made millionaires.
Self-made millionaire Steve Siebold, who interviewed 1,200 of the world's wealthiest people during the past three decades, agrees. As backward as it sounds, getting rich often has less to do with the money than the mentality, he writes in his book 'How Rich People Think.'
America's top earners are doing well for themselves.
The top 1% alone owns a shockingly large portion of the country's wealth: about 40%.
To see how you stack up against the wealthiest of the wealthy, The New York Times created an interactive tool that allows you to enter your household income and compare your earnings across 344 zones throughout the US.
Business Insider highlighted the annual household income required to be in the top 5% and top 1% in 13 major US cities.
As self-made millionaire and bestselling author Steve Siebold was leaving his house one day, he was flagged down by one of the men working on its renovation.
'It's not fair,' the man told him. 'You have this beautiful home and a nice car while we are stuck doing hard labour for just a little more than minimum wage.'
Siebold spent over an hour talking to them about his journey out of $50,000 of debt.
About six months later, he ran into one of the men again. He writes: 'A man driving a truck down the street stops in front of my house and yells, 'Mr. Siebold, I took your advice and started my own company. I have five employees working for me and business is booming. My family and I are experiencing freedom like we never thought possible.''
Here, he shares what he told those men.
So you aren't in the 1% of earners in your city. What about the top half?
In the New York City metro area, for example, if you're earning $52,000 a year, you're earning more than half the population.
That's according to an interactive tool from The New York Times that allows you to enter your household income and compare your earnings across 344 zones throughout the US.
In this post, we highlighted the annual household income required to be in the top 25% and top 50% in 19 major US metro areas, from lowest to highest.
I was earning $500,000 a year at 30: Here are the 10 best pieces of advice I can give you about money
After graduating from college, Cary Carbonaro moved quickly up the corporate ladder, including eight years on Wall Street.
'I was earning $500,000 a year at age 30, but I felt like I wasn't making much money because I was in an established industry without big stock options,' she writes. 'It was conservative and I was conservative. It didn't fulfil me. I felt like I wasn't making a good difference in anyone's life.'
So she left, striking out on her own as a financial planner. 'I went from $500,000 income a year to almost zero the next,' she writes. 'It challenged me personally, professionally and emotionally.'
Using data from the Minnesota Population Center's 2014 'American Community Survey' in the Integrated Public Use Microdata Series, we found the median annual total personal income for employed millennials.
We used the Pew Research Center's definition of millennials: Americans born between 1981 and 1997.
The medians ranged between a low of $18,000 per year in Montana and a high of $43,000 in the District of Columbia.
