I left college in 2014 with about $44000 worth of loans--$30000 federal, $14000 from the school itself. Joined Peace Corps in 2015, and after 2 years, I got about $3000 cancelled from my Federal Perkins Loans through the school.
Interest had accrued quite a bit by the time I left Peace Corps in 2017, and I'd been on $0 payments through plans like PAYE and SAVE, and applying for Forbearance here and there.
After Peace Corps, I continued to work in the country that I served in and steadily chipped away at the higher interest loans (7% from the school, 6.8% for some of the later federal loans). The housing provided by my employer here meant that I didn't have to pay rent, so all of my salary could be divided into just savings and food/entertainment. Once I had just lower interest loans (3.4-3.8%) left, I began building up my emergency fund and just making smaller payments of ~$500/month.
This month, I had a balance of $5500 left and since I had been saving up money to buy an apartment in this country, I decided to just cut the debt out of the equation and finish it off.
In total, with an initially balance of $44000, I think I ended up paying about $20000 in interest over these 12 years.
It's such a big relief because while I was in Peace Corps, I had many sleepless nights where I wondered how I would ever get such a huge amount of money paid off. I know that I was rather fortunate to not have to take out a huge amount in comparison to some of the posts I've seen here, but this is still a massive accomplishment for me. Good luck to everyone else--you can do it!
