This link will help you work out the numbers.   You are 115lbs (give or take) and you are 5'4" or 64 inches tall.   Read off the intake number that is most appropriate for your activity level.  It's going to be 2100-2900 depending on how active you are.

Since you are a healthy weight, however, I would caution against calorie-counting.  At 14 your body is far from finished growing and needs good nutrition in order to carry on developing healthily.  You're almost certainly going to get taller and as your body matures from that of a girl to a woman you'll get a little heavier..... that's natural.  So your aim to 'maintain' has to bear that in mind.  This link http://www.eatwell.gov.uk/agesandstages/teens / has some excellent information on how you can be fit, well and grow healthily without counting calories but by getting a good diet and being active. 

I'm kind of in the same boat - being a teen who is almost ready to maintain. I just turned 18 and have lost around 20 pounds in the past 2 years, the bulk of them being in the past months. I've been eating from 1300-1450 calories a day with some exceptions (a little more or less on some days). I am almost a second size smaller which was my initial goal. I've read that once you start eating more you gain a bit of weight that eventually comes back off and since I don't really go by the scale, I wouldn't mind 4-5 pounds or so as long as my size stays the same. I work out about 5 times a week doing cardio and resistance which also brings me to another question: do I eat more but keep working out the same, work out less and eat more, or can I eat more and work out less at the same time???

Whatever happens next, eating more is a given....  Sub 1500 cals isn't recommended for anyone under 18.  Choose good quality wholefoods, plenty of vegetables, that kind of thing.   How much exercise you decide to do depends on one important question.  What are you happy to do on a regular basis?  If you enjoy working out 5 days a week and can see yourself doing that for the foreseeable future then tailor your calorie intake to that amount of activity.  If you think you're more likely to work out less going forward, tailor your intake to that level instead. 

Use the chart I posted in the first reply http://www.bcm.edu/cnrc/bodycomp/bmiz2.html  in order to work out the right kind of calorie intake for your particular stats and level of activity.

Thanks so much for that! Yeah, I'm thinking keeping up the excercise would be best. That and gradually increasing my intake is what I should do.
