If you got a great job right out of college, your financial situation could have improved dramatically since you took out your loan. That means you could qualify for lower interest rates than you did originally — which means refinancing your loan could save you money over time. Check out your credit score (700 and up is usually considered good) and then talk to lenders to see if you can get a better deal than you have now. Even if you don't need lower payments, it's worth investigating refinancing because it has the potential to save you thousands of dollars — and the sooner you refinance the more you'll save. You just won't know until you check out your refinancing options.
