Example calculations
Tap an example to prefill the calculator with sample values.
Coaster set batch
120 ml pours across 6 pieces
A practical Etsy-style run where mica powder and a moderate 2:1 resin kit both matter to the final per-piece baseline.
Result: The batch cost is still manageable, but the per-piece floor is high enough that underpricing becomes easy.
Serving tray pour
420 ml piece with heavier decorative spend
Larger statement pieces make resin volume dominate quickly, especially when dried flowers or metallic pigments are included.
Result: Big pours feel premium, but material cost climbs fast enough that the batch needs intentional pricing.
Small jewelry batch
28 ml pieces across 18 molds
A tiny-piece workflow where low per-piece volume is offset by the fact that you still lose material to mixing cups and overflow.
Result: Small molds look cheap one by one, but the total mixed batch still needs a real materials budget.
How the resin cost estimate works
The calculator turns per-piece mold volume and batch size into a total mixed-pour volume, then adds a small fixed working buffer so the result behaves more like a real session with cup loss and cleanup waste.
It then splits that volume into resin and hardener based on the selected ratio, prices the total mixed batch from your kit cost per liter, and adds any one-batch colorant or inclusions cost before dividing everything by the finished piece count.
Resin art cost FAQs
Understand the working buffer, mix-ratio split, and why this result is a floor instead of a final retail price.
Why is there a built-in working buffer?
Because resin work rarely uses every milliliter perfectly. A small buffer covers cup loss, overflow, scraping waste, and tiny spills so the result behaves more like a real craft session instead of a perfect lab pour.
Does this include labor or finishing time?
No. This version is a material-cost floor only. If you sell finished pieces, add labor, sanding, doming, packaging, marketplace fees, and shipping on top of the number shown here.
How should I estimate mold volume if I do not know it yet?
The easiest workflow is to fill the mold cavity with water, then measure the water volume in milliliters. That gives you a good starting point for the finished mixed volume the resin pour needs to cover.
