Frequently asked questions
What is the monthly payment on a $40,000 student loan?
On the standard 10-year plan at 6.5%, $40,000 runs about $454 a month. Extending to 20 years lowers the payment to about $298 but roughly doubles the interest.
How can I pay off a $40,000 student loan faster?
Pay more than the minimum — the extra goes straight to principal — and target your highest-rate loan first. Refinancing to a lower rate can help too, but weigh it against the federal protections you'd give up.
