How much should i sell my nikon d5100 for?

I have a nikon d5100 in good condition i have used it a few times but not many its been mainly in my closet for the year. How much should I sell it for? I need the money to pay off my credit card thats another reason why i'm selling it.

Added (1). Yes i'm selling it with the kit lens

A used one in good condition can go for approx. $550. You might be able to go a little higher.

$500-$600 for body only

If you add the kit lens, you can possibly sell it for about $100 more.

Currently you can get the D5100 with the kit lens, new for $700

i'd start at $600 and go down from there
