Rent and food will be your biggest expenses, but like you mentioned if you ditch your car, take on roommates, and don’t have a healthy thirst for $15 cocktails (PBR is easily found for $3 or less in Brooklyn) then you can get by and still have a good quality of living on $60k when you’re 25.
You really need to look at your bills and see where you spend most of your money, how much you can save, and then Craigslist + COL calculators are good at figuring out what will cost more or less. Your cost of food per month could easily jump 40%+ but it depends on plenty of factors eg. are you shopping at a Korean Grocery store or Whole Foods ($7 for strawberries?!).
Quality of life is also an issue. Are you happy living where you are now? NYC is a great place to live if that’s what you’re into, so all the money in the world can’t make it exciting to live somewhere deep in the rust belt.
