If I eat 1600 calories per day will I still gain weight?

I am 5'2" female. The calculator says 1800 per day is needed to gain 1 lb a week but I am often not meeting that goal. But I know I am at least above the amount needed to maintain current weight so my theory is that I will still gain some weight. It has been challenging to constantly eat and all I'm getting is a bigger stomach.
