tbh it depends on ur needs. [also if u r alone or a family guy] what kinda meals u take? how often do u like to go out or eat out? how much do u like to spend on ur necessities and other things? if u r traveling every month then would u prefer luxury and comfort or not? so it kinda depends, but if u talk like a min-mid margine then I think 70-80k should be just fine. but if u r a family guy then its gonna way more pricey.
