Everyone is different, so it's hard to say. A very general guide is to take 10 times your body weight- that will likely get you in the ballpark, but for someone your age it's probably going to be low.
Hope that helps a little,

I was windering how many calories a teen burns in a day before exercise? I'm 5'9'' and 149 pounds, if that factors it in any way. Thanks!!
