How to Price Resin Crafts, Tumblers & Coasters
Mixed ounces, not bottle ounces, are what you use. Failed pours need a waste line.
Measure the mold, then the mix
Use the Resin Volume Calculator to estimate ounces from shape and depth. Add extra for cups, sticks and the last bit that will not scrape out.
Split that mixed amount by the manufacturer ratio. A 2:1 pour that you treat like 1:1 will either starve the cure or waste resin — both are cost problems.
Pricing epoxy tumblers and custom cups
Custom epoxy tumblers require multiple coats of epoxy, glitters, inks, decals, and drying on cup turners. Calculate the cost of the blank tumbler, 1.5–3 oz of total epoxy, vinyl/glitter, and 30–60 minutes of hands-on labor across prep, taping, pouring, and cleaning.
Molds are a per-cast cost
Divide mold price by the number of good casts you expect. A $18 mold used 12 times is $1.50 in each piece before resin goes in.
