Finally, a moral answer. Funny how a hooray-religion site such as this have people suggesting to keep something monumentally important from someone's father. What happened to honor thy mother and father? Honor is truth. Be truthful. If you decide to tell, then it's because you want him to know. If you want him to know, tell him. Whether or not he accepts it, you won't know. Time will tell. As I've found out, people can surprise you when you least expect it. Your father will not disown you. He loves you. Otherwise, you'd be paying your own way through college. It may take him time to accept it, and he may never, however, he will love you for he's your father. If it's your decision to come out, don't weigh financial gains on it. This should have nothing to do with money. That's exactly what's wrong with this world today. Money overshadowing everything. The all mighty dollar isn't worth anyone's life...
sorry... that last part was my thing, but I think it applies here, too. Be true to yourself. In the end, that's all that really matters.
