Start from what you need
Work out how many paid hours you can realistically teach in a week, remembering preparation and admin, and what you want to earn from them. That gives a lower bound.
Compare with the market
Look at what similar tutors charge for the same subject, level and format. Exam-level and specialist subjects usually support higher rates than general homework help.
Decide your terms up front
- Length and price of the trial session.
- Cancellation notice and what happens when a lesson is missed.
- Whether you offer block bookings.
Stating these in your profile avoids awkward conversations later.
Review regularly
If your diary fills quickly, your rate may be too low. If you get no enquiries, check your profile and niche before cutting your price.
