… well that depends upon where you coming from. If you are coming from US, UK, Australia or any other developed nation then you would find Korea much much cheaper. But if you are coming from a developing country like India, Pakistan, Bangladesh, Nepal etc. then it is definitely expensive as compared to your home country.
For this article I’d comparing the expenses with Mumbai, India. First, we will talk about accommodation. As I come from Mumbai I feel the house rent in Seoul is equivalent to Mumbai rentals. For Rs. 20,000 to 25,000 you might get a 1 BHK flat in Andheri, Powai area of Mumbai where as in Seoul you might get a studio apartment or a house with 2 rooms for Rs. 20,000 ($500). So rent wise I feel Seoul is not that expensive.
