PS> This is the cost for high living expats, renting luxurious condominium apartments, driving cars and eating in expensive restaurants, not for locals living in owned HDB flats, travelling by MRT or bus and eating in hawker centres. But even for Singaporeans and PRs, Singapore is an expensive place to live compared to other countries in the region. The higher wages in Singapore compensate for that though.
