It depends a lot on the ingredients that you are using and the amounts. Typically 2 pieces of bread will contain between 150 and 200 calories. One tablespoon of peanut butter is around 100 calories and one tablespoon of jelly is around 50 calories. If you're like me and like a lot of peanut butter and not as much jelly then you probably use 2-3 tablespoons of peanut butter and 1-2 tablespoons of jelly. That would give you a total of anywhere from 400 - 600 calories, but will depend on you preferences.
