Am I charging enough to live on?

I work for myself as in and charge . I want to know whether that rate adds up to a living. I need to take home about after tax, and my yearly business costs are roughly . Ask me up to four questions, one at a time, about the hours I really bill, time off, and unpaid work such as admin and finding clients. Then show the math in a short table: what I earn per hour once unpaid time is counted, the minimum rate my numbers require, and the gap between that and what I charge. Treat tax as a rough placeholder, say what percentage you assumed, and remind me to confirm it with an accountant. List every other assumption.
