How to use this calculator

Build a line-item materials list for your workshop or art class, and see the per-student cost with a waste buffer for losses. The output prints as a clean one-page summary that works as an attachment for class proposals.

  1. Set your expected number of students.
  2. Add a line item for each material: name, unit cost, and units per student.
  3. Click Add Material for additional items, or the × button to remove one.
  4. Adjust the waste buffer if your class is more advanced (lower) or more beginner (higher).
  5. Print or save the PDF to attach to your class proposal.

Frequently asked questions

What if my class only has 3 students?

Change the student count and watch what happens. Per-head cost climbs as fixed materials (a shared bag of clay, a jar of medium) spread across fewer participants. The comparison line at the bottom shows how much the per-head cost shifts with two more students enrolled.

Why a 15 percent waste buffer?

Students drop, materials get over-applied, tubes get squeezed too hard, things break in the kiln. Fifteen percent absorbs typical losses without being padding. For introductory workshops with a lot of beginners, 20 to 25 percent is more honest.

Can I share this calculation with my class proposal?

Yes. The print and save-PDF output is built for this purpose. Many community education programs require teachers to itemize material costs as part of the class proposal; this gives you a one-page summary with the line items visible.

What materials should I include?

Everything that ends up in the student's hands plus expendables (glaze, fixative, masking tape, shared paper towels). Leave out anything that comes back to your stock (brushes you reuse, tools you provide).

Should I add my teaching labor here?

No. Labor belongs in the class price calculation, not the material cost. Calculate materials here; calculate the full class price (with instructor time, overhead, margin, and enrollment scenarios) in Class Price Calculator.
