This question has been asked about 5 times a week for eons.
Everyone here pretty much knows my opinion, and that is the fact that all of the online calculators are "guestimates". The only way to know what calorie level will work for you, is to pick a starting point of about 1800 calories a day, do it for a week, and weigh in and see what happens. If you lose 1/2-2 pounds, then this is the level for you-if not, then go down about 100 calories a day and try that for a week. Trial and error is how you find the right calorie level for you.
