You need somewhere between 1000 and 3000 calories for weight loss.
Seriously, no one can answer your question. So many variables, plus many will tell you calories don't matter so don't count them.
I'm 46, 5'11, male, been following PB for a little over a year and went from 220 to 170 in that time. I counted calories a little when I hit stalls, and found I could eat around 2500 calories at first and lose weight but now I need around 1500 to lose.
If you eat right and exercise, you will feel full, not have the urge to snack and spontaneously increase your activity level because you feel so good. You need to lose the 'how many calories do I need' mentality and start eating right first and foremost. If you are eating right and still not losing, then count your calories and restrict a bit.
