Personally, I have an all-inclusive fee model in my studio. If you don’t, I think it’s essential these days to charge some kind of fee for the digital resources you purchase for your students.
Make a list of what you usually spend in a year on digital resources like memberships (hello there, VMT!), apps and studio-licensed materials your students don’t directly reimburse you for. Add up the total and divide by the number of students in your studio. Consider charging this as a registration fee or allowing for it when you calculate your tuition fees.
