Some interesting points of view coming out. My philosophy is slightly different, you mention charge enough for when there's quiet times. I don't think it's fair for the client to pay extra for that. My clients come back to me because they know they are getting a good rate and because they get first class product, which means they keep coming back so no need to stash the cash for those quiet moments. Most clients have a budget anyway and dictate how much they want to spend on a project and it's up to you to either except that or not. £20 per hour=£160 a day (only 8 hours a day)is £3200 a month x 12 =£38,400 a year it pays the bills. Though I am thinking of putting up my prices at the end of my tax year. Maybe a fiver extra per hour.
