You'd really have to consult with a Realtor in your area to determine that. It also depends on your specific neighborhood and what people expect from the homes there. For example, if your home only has 1.5 baths and most of the houses in your neighborhood have 2 or 2.5 baths, then it could make sense to convert the half bath to a full one. On the other hand, if your house already has 2.5 baths and you're converting a half bath to a full one, it might not make as much sense.
Similarly, in some areas garages are very highly valued. Lots of people won't buy homes without garages. If you're in a neighborhood mostly with 3 bedroom homes, it might not make sense to add a 4th bedroom (which wouldn't be highly valued) while sacrificing a 2-car garage. So, it really depends.
What you really ought to do, first, is determine what will make the home more liveable for you. If you really need that 4th bedroom and really need another full bath, that's fine. Still, since you're concerned about adding value to your home, check with a Realtor. In many areas, a 4th bedroom will add a little, but not too much. Converting a half bath to a full bath will add a little; it'll add more if you only have one full bath at the moment. It won't add very much if you already have 2 full baths.
You'll find that very few improvements return 100% of the cost. Adding a full bath to a home that only has one probably will. Doing a moderate rehab on a severely dated kitchen probably will. Adding a 4th bedroom and sacrificing the garage probably won't. Adding skylights won't. Finishing an unfinished basement might. Again, though, a lot really depends on what's expected from the homes in your neighborhood.
Hope that helps.
