Does baked bread have the same amount of calories as its ingredients?
Yes, the yeast does consume sugar to produce the bubbles in the dough, but I don't think it would be more than a few grams. During the baking of the bread, some water and alcohol evaporates and proteins are denatured. 

Denaturing proteins does not change the calories. Since the alcohol that was produced is lost, then the calories are reduced. Water doesn't have any calories.

So, to answer to the question in the title: there are fewer calories in the baked bread than in the ingredients. Unfortunately, it cannot be predicted, the bread needs to be tested.
