For online chess lessons, my rates are as follows:
Introductory 1-hour lesson: $50
1 hour: $70
3 hours: $195
6 hours: $350
When I get a new student, I always ask for their latest games so I can analyze them to find their strengths and weaknesses and so we can discuss them together. I always answer any questions my students may have because I feel that is the main benefit of having a live lesson; you cannot ask questions of a book, article, or prerecorded video.
After the lesson, I always send the materials through to my students so they can review them in the future.
