How much do you have to spend per month on basic needs in your country?

In Singapore a person should be spending more than 800SGD to 1000SGD per month on basic needs to survive. I really hate the fact that Singapore is one of the most expensive countries to live in due to it being a very small island with limited land. Cars and houses were the most expensive here.
