<prompt> Human: I just moved out onto my own and my parents told me very little about how money works, and my dad being a doctor we didnt have money problems, until he passed away with a quarter million in debt I think, thats what my mom told me.So I just graduated high school last year, and some how managed to get a pretty good job at a small ISP, however Ive heard this company doesnt pay very well. I calculated what I thought my income and expenses would be and I calculated I would have around 400 after expenses each month. Then my mom reminded me that taxes exist, and my moms friend said it would be around a third of my income. So now Im confused. Here is my math, I really know very little about how this works so I may be way off:13hour 40 hours a week 520week 4 weeks in a month 2080 a month.Supposed 13rd out from tax 1387 a month.1387m ------Rent 1000Cable 53Food 10 a day 300Electric high est. 110Total 1463So I dont know if this is right or what to do. I put a 0 on my tax form from work, this is in California if it helps. I want to know if I got my math right, if there are any other fees Im not thinking of, and if 13rd out from tax is accurate.  <response>: Here is an online calculator to help you estimate your take home pay:A good rule of thumb is that you should pay about 13 of your monthly income in rent. Half your income can work but is pushing it. You are paying more than you can afford. Unfortunately, in some places with higher cost of living, its hard to pay your bills while working a low-wage job.
