I suggest you search for "cost of living in Malaysia" and compare the indices for Malaysia and India. I suspect the cost of living index is slightly higher in Malaysia so do the math with what you get now and multiply it by the ratio of the indices to see what a comparable salary in MY would be relative to your IN salary. You'll probably have to factor in additional things like transportation, room and board, phone calls back home, internet subscriptions, and occasional travel back home to get a realistic idea of the difference
you should be looking for to make working abroad worth the sacrifice.
