If you are in twenties or early thirties and remain single, earn $3,000 after tax per month, you will probably save $1,000 if you, let's say, spend $500 to $800 on rental, a guest bedroom in a shared house/apartment, $500 on food, $50 on utilities, $150 on phone/internet bills, $400 on commuting costs or gas/maintainance if you have a used car, $200 on occasional entertainment or others. This $1,000 savings will allow you to invest or place a house down payment when time is ripe. Is this possible based on where you live ?
It is applicable to you according to the cost of your country which you have calculated here. If I spend here according to the customs of the country I live in, I will spend only $1500 of the $3000 per month. Now everything is going up in price. Living now has changed a lot compared to the previous life. If everything had not gone up in price, maybe I could have saved $2,000 out of $3,000 based on my country's cost. So I think right now there is not much difference in cost as per your country as well as in my country.
That's totally depends on your pay scales your country is offering and the inflation rate in that country .
Where I live the wages are low and inflation is high so saving is impossible, you hardly meet your expenses to provide food and basic facilities to your family .
