Study Task 6 - How Much Do You Need

From estimating a break down of my living costs as a student, I have worked out that I spend around £9973.20 annually. I am currently seeking freelance work during my studies and must have a suitable hourly and daily rate to quote potential clients with. To break even I must earn £831.10 a month. If I work at £13 p/h at 8hrs a day, I would have a daily rate of £104. At this rate I would work for 8 days a month to break even. Working at the same rate for the other 3 weeks  in one month would  I profit at 3x the income I would need to cover living costs.
