Userscripts Bend the web to your will

Be sure to have Greasemonkey installed.

I wanted to see details on payments, such as "How long would it take to pay off this loan at the current minimum balance?" and "What date would my final payment be at this rate?". This script answers those questions right on your account page.

My account is no longer through SallyMae, so this script may self deprecate at any time.

Paying more than the minimum routes you to a page where you designate where to apply the extra funds. This script highlights the sub loan with the highest total balance, making it easier to spot the loan causing the most interest in the long run.
