How a Rocket Scientist Manages His Money

Jason Lowery is a typical 29-year-old who likes hanging out with friends, loves his family and spends weekends tinkering on his hobby car, a 1969 Chevrolet Chevelle. But unlike most of his peers, he's completely debt-free, right down to his college tuition.

Born in the "lowly little" town (as he jokingly puts it) of Lilburn, Georgia, Lowery did well for himself. He graduated from Baylor University, in Waco, Texas, in 2010 with a bachelor of science in Mechanical Engineering with a minor in Mathematics. He is currently in grad school at the Air Force Institute of Technology, working toward earning a Master of Science in Astronautical Engineering with a certificate in Systems Engineering.

While most of Lowery's undergraduate tab was picked up by the Air Force Reserve, which he joined freshman year, he still left college owing $60,000 in student loans. To add to that, his late mother had a whopping $20,000 in credit card debt.

For someone whose parents always viewed themselves as being on top of their finances, Lowery was stunned when he found out about her debt. "My mom lost a lot of pride by having to handle that," he said.

So he came up with a plan. "I said, 'Tell you what. If you pay off $20,000 of my loans in your name, I'll pay off your credit cards, and do it quickly," Lowery recalled. In a year and a half, he would consolidate all his mother's credit cards. Then, as his parents assumed his loan for $20,000, Lowery prepared to spend the next three years of his life paying off the remaining $40,000 in student loans — as well as those credit cards.

"I paid off all debts, including my mom's, between January 2011 and February 2014," Lowery said. "I paid my last bill 25 days after she died. It felt like kind of a proud tribute to her and all she taught me. Also served as a huge perspective change — life after debt corresponds with life after Mom."

Here's how Lowery did it, and what you can learn from him about managing money.

A Crash Course in Differential Equations

To tackle his mother's credit card debt, Lowery listed every card she had, noting its balance and interest rate. He said it's a differential equations trick. "I figured out every possible equation and chose the one that would amount to me paying the least amount in interest." In the end, he went with the snowball method, paying off her debts in order from the smallest balance to largest, regardless of interest rate or monthly payment requirements.

"She had one card with $2,500 and a 29% rate, and I just nuked that card in two-and-a-half months," Lowery proudly said.
