I was very lucky to have landed a full-time job before graduation, my dream job actually (read: Vancouver 2010 Olympics!). This was an 18-month contract, and I knew that I wanted to have this student loan off my back before the contract ended. I set myself a lofty goal of 1 year....eek, that's $2,750/month not factoring interest. "Okay, I can do it".
Here's how I ditched the debt (including interest):
1) I paid a minimum of $1700 per month onto my debt = $22,400
2) I applied my tax refund onto my debt = $5,400
3) I sold my car = $1,800
4) I put every per diem cheque from work onto my debt = $7,000
5) I put every birthday/christmas money onto my debt = $600
I was fortunate enough have a parent who let me live rent-free while I was paying down my debt. I was fortunate enough to have a job that provided me with a vehicle, so I was able to sell the car I'd had since high school. My job paid us $60/day per diems, and since we'd generally be too busy to eat we usually netted at least $35/pay. More than 200 days on the road sure adds up.
It wasn't easy, but I was able to pay off my loan in 10 months, 2 months shy of my goal!
