Living in some countries with $833 salary a month can not be enough because the renting of houses or flats are very expensive and the life standard is high which makes the income of people to be higher too.
Living in Western Europe, $833 is nearly just the cost of your house that you either pay as rent, or as mortgage. And then you only did that. You still have all other costs that you have to pay for. Especially a difficulty in the times where prices of goods only go up.
If I look at myself, then I solidly keep 30% of my salary as being savings. In previous years I could easily have 35-40% of my salary moved to my savings, but just because everything has gone up in price, different tax policies, I am only able to have the percentage sit at 30%. And that while I am doing exactly the same with my money as I have always done.
The eurozone standard has been increased too much recently and the living expenses has been increased drammatically comparing with a decade or more ago. That's why $800 does not have the same value around the world, I try also to save 30% of my total income but it's not easy.
