The number of calories needed is different for every person, depending on your size and activity level there is no one number for everyone.
For example:
I am currently on 2500 calories a day, my missus is on 1500 calories per day, we are both training and eating to drop some body fat, yet I seem to be dropping more weight per week than what she does.
I am guessing my maintenance is around 2800-3000 calories per day at my current activity level.
Personally if I was clean bulking I would be eating around 3000-3300 for starters and then adjust from there, this is for me at my current activity level, every other person will be different.
For the purpose of a fat loss plan you should be looking at somewhere between 18-29 calories per kilo of body weight per day. And keep in mind that you need to maintain 2 grams of protein, 0.85 grams of fat per kilo of of body weight to maintain normal hormonal function and minimize loss of lean body mass while cutting.
For a clean bulk you need to look at 22 to 35 calories per day per kilo of body weight.
I am currently on 22 calories per kilo of body weight doing a cut, so you can see the calorie intake overlaps depending on you metabolism and activity level I would probably clean bulk at 28 calories per kilo of body weight for starters and adjust from there.
