muscle building and calories?

I found a calorie calculator that said to maintain my weight, i need roughly 1900 cals. To lose weight, I need roughly 1500. I am doing moderate excercise to build some muscle, squats, bicep and triceps with weights, ect.

I know a pound of muscle burns more cals at rest than a pound of fat does. So if I lost ten pounds of fat, but put on ten pounds of muscle, would my maintain cal amount and lose weight cal amount stay the same, go up, go down?
