If You Had To Live on $2000 USD Per Month, How Would You Do It?
I have already done this and don't spend much more than this on myself today. Much harder when you have to support a family or want to live with nicer things! Much easier to do when not in an expensive city.
This is usually the biggest cost. I'll be generous and say 1k you can either find a one-bedroom apartment or get a nice place with others. This includes utilities.
200 bucks a month for their best plan. Used this when I had my own business and it worked great. Everything over 500 bucks was reimbursed 100%. There are likely similar programs for different religions.
1 person should be able to eat for under 100 bucks a week. If you cook at home. You can eat quite well, actually. Skip breakfast, as @randomroger said.
Buy a bike. Use the bus. Let's give 100 bucks a month for uber/lyft in a jam.
5. Cell phone
Should be able to get a plan for 30-40 bucks a month.
Big cost, if you really only make 20-30k a year, you might qualify for a discount, or even free internet, in some cases. I'll go nuts and say it's 80 bucks.
You'll need to find free things to do. Parks. Museums. Free live events. But, let's also get a Netflix subscription. 12 bucks, I think? It might be smarter to get Amazon prime, so you get movies and get free shipping for things.
Let's also give 25 bucks a week for other entertainment. That will get you a meal out. Or a few drinks at a decent bar. See a movie, or two.
8. Odds and Ends
You'll need toothpaste, tissue paper, etc. That 68 a month should roughly cover it.....
Could get a gym membership for 20-30 bucks. Part of entertainment? Or live in a cheaper place. There you can take free showers. Some have free snacks. You'll be around people.
10. This is doable
Not to mention, if I only had 2k a month to spend, I would not spend 1k a month on housing. You can cut that down a lot and maybe even have some room for savings!
