Here's a bit of arithmetic, positing a girl with a fairly modest level of activity .
£80 for half-an-hour is an average-ish rate these days (although of course prices vary wildly). If our notional escort does two half-hour bookings a day, five days a week – and takes Saturday and Sunday off – that's £800 a week, or £41,600 a year.
Not bad, eh?
For five hours' work a week.
Sadly, however, almost all the escorts I have known well enough to have knowledge of their approach to money management have been spendthrifts, to whom the concept of saving or prioritising is alien. So the money is spent almost as soon as it comes in. It's not difficult to get through £10,000 a year on weed, for example.
My guess is that the escorts who contribute to this site manage their money well, and will have a different story to tell.
But my experience is as I have described it – with the result that many of the girls who do this well-paid job (albeit a job that not many of us, if the roles were reversed, would much fancy) never have a penny in the bank, in spite of the fact that they are earning above the average national wage.
