What's the real cost with all these builder extras?

Noida Extension — I'm really getting confused with all these extra charges. My current 2BHK deal didn't have so many surprises, but now for a 3BHK, builders like ATS ya Godrej Properties ek price batate hain, then PLC, EDC, maintenance deposit, registry fees... sab add ho jaata hai. Kitna extra paisa laga end mein? Bahut frustrating hai, yaar.
