How much a day of your life cost?

Doing a bit of research to see where we stand in terms of our financials, so I took all of our expenses and tried to work out a daily cost of living. Taking food, rent, transport, bills, medical costs, and all those other things that add up works out to anywhere between $37-50 per day,

I feel like I live quite frugally, we likely eat one meal and have a smoothie/soup for the other meals, currently not using a car and don't need to use public transport as everything is within walking distance, my GP is $15 per visit and still not paying for medications.
