Hi was there in Havelock a week back .If its a sudden plan the flight will cost you around 30k for 2. If you book in advance wil cost 23k around . From portblair up and down ferry 5500 for 2 .
3500 is min cost for a night. If its 3 nights around 11k .
Other transports 4k . water sports u can spent 10k for 2 .
Havelock is expensive
Manoj is right. flight budget totally depends on advance booking and travel period. if it's in vacation than it would be higher than that. I've paid 20k p.p. from Mumbai on Diwali. other budget is given by Manoj is quite exact.
For 4 days 3 nights, it will cost around 10.5K approximately. And my suggestion is, just explore Andaman for 7 days 6 nights where you will get various adventure things to try there. If you are looking for the itinerary, check https://www.funstay.in/andaman-tour-packages
