If you are currently a college student, this is probably the most important Melon post you’ll ever read. Why? Because I’m about to tell you something that will save you tens of thousands of dollars when done correctly. Not only that, you’re going to get this money for not doing something. It’s hard to find a better deal than that.
You’re not going to pay back your student loans. Okay, more specifically, you’re only going to pay the minimum amount required on for as long as possible.
“Why?“I’ve been asked countless times when explaining this idea of mine to my fellow students. It sounds crazy, but it works.
If you have student loans, you probably received them at a certain interest rate: Likely 5% for Perkins loans and 6.8% for Stafford loans (which, depending on when you received it, may go down to as far as 3.4% in 2011 according to this site). After college, you should consolidate your loans, if it is prudent to do so. Consolidating costs nothing and can be done for federal loans at this site with no cost. Generally, your repayment period will be extended to 20-30 years, depending on how many total loans you have.
I’ll use myself as an example. I will graduate from The University of Puget Sound in May 2009 with $26,870 in student loan debt from Perkins and Stafford loans. Let’s say I wait until July 2011 and consolidate my loans, locking in an interest rate of between 3.4% and 5%, depending on my loan mix. With an interest rate this low, why would I want to pay my loan off? If I do that, I will effectively be losing money.
Look at it another way. If I gave you a $1000 loan at 5% interest and you turned around and invested that in the stock market at 10% interest, over a year, you just made $100, $50 of that which you now pay to me, so you walk away with $50 in your pocket. If you managed to pay the loan off right away, you maybe owe me three or four dollars in interest. You might look at this as a good deal, but if you had decided to draw out the contract as long as possible, you would have made $50!
Student loans are basically “free” government money for you to turn around and invest in the stock market.
What about for the doubters that cite our hard financial times as a reason to pay off your debt right away? What about those of you reading this right now and saying “I don’t trust the stock market!” I’ll show you why this will work. Using the Standard and Poor 500, as a benchmark, the stock market has grown 9.4% on average annually from 1871 to December 2005 (Source). This includes the great depression, this includes every financial crisis in the last 130 years of which this current one is just another drop in the bucket. However much I disagree with capitalism, the administration, et cetera, I will bet every single time on the stock market as opposed to keeping my money in a coffee can over the 20-25 year period in which I’m going to be paying off my loan.
Back to me as an example. My 26,870 in student loan debt is going to be invested in the stock market. To account for fees and such, lets say I average a rate of return of 8% annually during my loan payoff period over the next 20 years. Let’s say I am able to consolidate my student loans at 5%. For these 20 years, I steadily plug away at my loan, paying only the bare minimum every month. Meanwhile, my effective interest rate is 3% because I’m turning around and investing the government’s money in the stock market and keeping the interest. My 26,870 just turned into 48,530.21 over that period.

To summarize:
1. Consolidate your loans once you graduate.
2. Invest.
3. Pay off only the minimums on your loans every month.
4. Profit.
Disclaimer: There are a lot more factors at work here, this is just a gross oversimplification because I know my target audience is not that of a finance blog. There is the factor, for example, that student loan interest is tax-deductible, which even further reinforces my argument. This method will also not work if your loan interest rate is over about 8%. In that case, you should pay it off as soon as possible. If anyone has any specific questions, I can address them in the comments section.
