The correct answer is 100k is chump change! News flash you have to finance your retirement nowadays. So out of the 100k that you won’t make, 30k will go to the gov as income tax, now you have 70k. To fund your retirement you need to contribute the max of 15k to your 401k, now you have 55k. 55/12= 4583 per month so, a avg house will run you about 2000(assuming you want to live in a relatively safe area) of your 4583, now you have 2583, figure about 500 for gas, 200 for car insurance, 500 for car payments, 200 for utilities, 150 for cell phones, 500 for food, student loans 300, and 250 on whatever else. Now you are out of money until next month.

My father-in-law said his gas bill was 2800 dollars last month alone. He said he needs at least 10k a month just to get by, and he is pretty tight with his cash and lives in a modest house and drives avg vehicles.

Your parents could get by on 60k because they bought their house in 1980 for 70k and ad pay a 500 dollar a month mortgage.

My point is, that with a family 100k is just getting by.
