How much to charge for one-on-one tutoring?

This one is usually asked by people who tutor rather than by parents, so, briefly: price against your local market and your actual experience, charge for the planning and marking you do outside the hour instead of pretending it is free, and publish one rate rather than negotiating each time. Advertising a low headline rate and then adding materials or registration fees is the practice that makes families distrust tutors in general. For what this tutor charges, the pricing page has it.
