In the United States, as a single man you should make AT LEAST twice your age times $1,000 and it varies by city.
Bare Minimum income for single male = (AGE X 2 ) X 1,000
So if you're 30 you should be making at least $60K
Comfortable Minimum income for single male = ( AGE X 2.5 ) X 1,000
So if you're 30 you need to be making at least $90K
Again, it varies by city. Like making $100K in Atlanta barely keeps you afloat. So i would assume it's more in places like New York or San Francisco.
If you cant survive off 100k in Atlanta or nyc, you got bad spending habits
