Am I eating the right number of calories?

Options
I have been trying to find the correct number of calories for me to lose the last 20 lbs. I am a 28F, 180lbs, lightly active (stay at home mom), work out at least 5 days a week for at least a half hour. I usually burn at least 400 calories. MFP and other "experts" have given me anywhere from 1,250 calories a day to 1,600 a day. I just want to make sure I am eating enough to lose weight and not gain it. I prefer not to eat my activity calories if possible. Right now I have it set at about 1,400 calories a day. This is stressful!
