She rents a 3-bedroom house for $1500 split 3-ways. Her rent is reduced to $500. Health Insurance stays the same at $200. Food cost increases to $600 split 3-ways, or $200. Utilities increase to $210 split 3-ways or $70. Cell increases to $90 for a family plan split 3-ways or $30. Fuel and car insurance increase to $250 to accommodate 3 drivers, split 3-ways by sharing the policy or $83. Car payment raises to $300 because she wants a reliable car. ($18,000 financed for 5 years at this rate) And then taxes, which you didn’t assign a value for. Let’s assign 28% of her paycheck to this, which is fair. I’m going to add TV, which she can get for free using and HD Antenna and bumming streaming service passwords. Another $25 for internet split 3-ways.
At $15 and 40 hrs. a week, she earns $2,400/mth. She may need 2 jobs to reach 40 hours, which is one of the downsides of being a basic skilled laborer. Take out $672 for taxes. Then take out $500, $200, $200, $70, $30, $83, $300 and $25. She has $320/mth. for incidentals (Car maintenance/repair, new kitchen appliance to share, etc.) entertainment, clothes, sundries, luxury expenses (Booze, fast food), etc. It would be hard to save, but that’s life permanently earning a salary meant for high school/college kids and those content with barely scraping out a living because they don’t want to explore other options.
She has a nice roof over her head (An entire house), health insurance, a decent car and all her necessities. But she can’t afford to live alone or spread her legs. If she wants to change that, she will need to aim higher. For the time being she is living comfortably with the ability to lower her costs, if needed. The onus is on her to budget.
