calories in/out

I understand the whole concept of calories in/calories out in terms of weight loss, but my question is this: here on this website, say I'm allowed 1200 calories a day. If I work out and burn 400 calories, it then says I've earned 400 calories from exercise and it'll increase my daily calorie goal for that day to 1600. So if the point is to make a deficit to lose weight, why do I want to add back in the calories I just burned?

    because the 1200 already builds in a deficit based on how much weight you said you wanted to lose.

    MFP uses the net calorie concept. It calculates your daily calories burned (basal metabolic rate) by normal activities and then depending on your weight loss goals it returns a caloric consumption you can take and lose the weight. However, if you burn more calories than your BMR then you need to consume those back or your weight loss will accelerate beyond your goal. It would not be healthy to burn tons of calories and put yourself in severe caloric deficiet.
