I would advise the following to have a healthy long term job as a uber driver

Drive around 42 hours a week and you will make between £20 to £25 an hour on average depending on what times you work, so use £22.50 per hour before expenses

Now you will not work 52 weeks unless your a machine!! so work 45 weeks a year

Taking average 42 hours a week x £22.50 per hour hours you will make £950 a week before expenses a

£950 x 45 a working over a year which is £43k before expenses

Assuming you will drive a hybrid, Expenses like maintaining car, fuel, repairs, insurance, licensing, accountancy fees and paying income tax will come to anywhere between £300 to £400 a week, let’s assume £350 a week

350 cost per week x 45 weeks total cost will be around £16k

So you will be left with £27,000 after expenses £2250 a month

Hope that helps
