Err yes... I too am in Mumbai. My phone bill comes to 1000/mo and traveling to about 2k but you got to budget for the occasional flight to meet potential investors or for a family emergency back home. So I think a net 5k a month average is reasonable. One could certainly get rid of the 15k a month but that would probably amount to getting rid of insurance and the national savings scheme and stuff like that. That's probably a personal call though...
