Skulls,
I pay ~$1,200 on health insurance and ~$1,000 on car insurance annually. My rent expense is $2,800 a year, or $700 month for a two bedroom unit/3 roommates. My utility bill ~$360 a year. My food expense is ~1,800 a year, or ~$150 a month. My gas expense is ~$600 a year, or $50 a month.
My total fixed expenses are thus ~$7,760. When we include taxes:
Federal Income Tax:
8,700 x .10 = 870
6,380 x .15 = 957
Total: 1,827
Social Security and Medicare:
15,080 x .062 = 934.96
15,080 x .0145 = 218.66
Total: 1,153.62
Total Federal + SS/Medicare: 2,980.62
State Taxes:
Lets just say 5%.
15,080 x .05 = 754
Total: $3734.62
So $15,080 - $3734.62 (taxes) - $7,760 (expenses) = $3585.38, or ~300.00 a month of extra income.
As you can see, cost sharing saves money. Although, in practice, I think I would get ~$600 of taxes back from the government. Additionally, I could also move to a state without state income taxes, or carpool with my roommates or use public transportation more often. Moreover, most full time jobs I get tend to pay at least $9.00 an hour here.
