Putting money on the card barely makes sense at all if you use the subway frequently. My honeymoon was in Manhattan for a week, and we were out and about every day. For a $30/person flat rate, you can use the subway unlimited times for a week. Even if you only use it 2 times per day, that's $35 at $2.50 per ride. The $30 was a much better deal for us, as we used the subway many times every day to get to museums, food, etc. For a month, it's a $112 flat rate, which comes out to ~$25.85/week. That means if you use the subway more than 10 times a week, it's better to get the month flat rate.
