Here's what the analysts came up with for a family of four:
Estimated cost of annual necessities: $84,972
Suggested annual discretionary spending: $50,983
Suggested annual savings: $33,989
Suggested annual take-home income: $169,944
So now you're backpedaling to a family of four, and any metric for NYC as a whole is stupidity, considering the insanely variable cost of rents by neighborhood.
Dude, you just don't know what you're talking about. Stop digging.
