Here is one I found today:

http://www.thinandhealthyforever.com/CalorieRequirement.asp

and I have found other calculators and they are all a little difference. This calculator for instance gives me more calories in order to lose 1 pound per week than MFP.
Can this be the reason not everyone lose weight like they should or losing more than they should?

    Most calculators have some flaws. MFP does too. My best advice is to run your numbers yourself.

    Calculate your BMR (http://www.bmi-calculator.net/bmr-calculator/ but most websites should give you similar numbers)

    Determine your activity multiplier. 1.2 for sedentary, 2.0 for athletes in training season or if you're trying to run a marathon or something, so likely something between those. (Remember 1.0 is your body in a coma.)

    Multiply your BMR by that and it should give you your TDEE.

    Subtract 500 from your TDEE to find out your daily total (not net) calorie goal to lose one pound per week. If you prefer to use net calories, consider your multiplier without your "formal" exercise (so do you walk around for your job, up and down stairs, taking care of kids) and then add in your exercise calories later.

    Remember they are estimates, pick one to try for about 4 weeks and than adjust slightly up or down

    The scales.

    (When I've kicked them around a little so the figure matches what I want :P )

    If they say I'm losing a lb a week, that's about as good as you get :).

    Noted that I use the 'libra' smartphone app which works out an average and takes out fluctuations and so on.
