How to Calculate Resin Art Cost Per Piece

Resin art looks effortlessly beautiful, but the supplies add up fast. Between epoxy resin, mica pigments, alcohol inks, glitter, silicone molds, and the butane torch you burn through every pour session, it is easy to underprice your work — or lose money without realizing it. This calculator gives you a clear cost-per-piece number before you pour a single batch.

What Goes Into Your Cost Per Piece

Every resin piece has four main cost buckets:

  • Epoxy resin — priced per ounce, this is usually your biggest expense. A standard tumbler uses roughly 1–2 oz; a 12-inch art panel can use 6–10 oz. Divide your bottle price by its total fluid ounces to get your per-oz rate.
  • Pigments and glitter — mica powders, alcohol inks, holographic glitters, and foils. These are small by weight but premium brands cost $5–$15 per pour depending on how heavily you color.
  • Mold cost (amortized) — a silicone coaster mold for $12 that produces 50 coasters before it wears out adds $0.24 per coaster. Divide the mold price by expected uses.
  • Other consumables — butane for your torch, mixing cups, stir sticks, gloves, resin cleaner, and UV-protective topcoat. Estimate $0.50–$2 per piece depending on project type.

Setting a Selling Price

A common handmade goods rule is a 3× keystone markup (200% markup) for retail. That means a piece costing $4 in materials sells for $12. For Etsy or craft fairs where you also absorb platform fees (6.5% Etsy transaction fee + 3% payment processing), many resin artists target a 4–5× markup to stay profitable after fees and shipping supplies.

Do not forget to value your time. If a set of four coasters takes you 45 minutes of active work plus cleanup, at $20/hr that is $15 in labor — more than most material costs. Pricing that accounts for labor prevents burnout and keeps your shop sustainable long term.

Resin Cost Benchmarks by Project Type

  • Coasters (4-pack): $3–$8 materials; retail $28–$48
  • Tumblers: $5–$12 materials (more resin, glitter); retail $35–$65
  • Small art panels (8×10): $8–$18 materials; retail $55–$120
  • Geode / ocean pour panels (16×20): $20–$45 materials; retail $150–$350

If your calculated cost pushes your retail price above market rate for your niche, look at buying resin in larger quantities (32 oz vs 16 oz bottles typically cut per-oz cost by 25–35%) or simplifying your color palette to reduce pigment spend.

Frequently Asked Questions

How do I calculate the cost of resin per ounce?
Divide the bottle price by the total fluid ounces in the bottle. For example, a $28 quart (32 oz) of epoxy resin costs $0.875 per oz. Then multiply by however many ounces you use per piece. Many two-part epoxies sell by weight — check whether the oz listed is fluid oz or weight oz, as they differ slightly.
How much resin does a coaster or tumbler use?
A standard 4-inch round coaster uses roughly 0.5–1 oz of mixed resin. A 20 oz tumbler spin coat uses about 1.5–2.5 oz per coat, and most tumblers get two coats, so budget 3–5 oz total. Larger pieces like ocean pour art panels (12×16 inches) can use 8–16 oz depending on pour depth.
What markup should I use for selling resin art?
A 200–300% materials markup (3×–4× keystone) is standard for handmade goods at craft fairs and on Etsy. If you sell on Etsy, factor in their 6.5% transaction fee plus 3% payment processing — many sellers use a 4× multiplier to absorb those costs and still clear a reasonable hourly wage. For wholesale to boutiques, price at 2× materials so the retailer can double it again for retail.
Should I include my labor cost in the resin calculator?
Yes — material cost alone understates your true cost of goods. Active resin work (mixing, pouring, swirling, torching) typically runs 15–45 minutes per piece depending on complexity, plus 24 hours of cure time. Add your hourly labor rate to the material total before applying your markup. Many resin sellers target $15–$25/hr for their time when selling on Etsy.
How do I amortize mold cost per piece?
Divide the mold price by the number of uses you expect before it degrades. A quality silicone coaster mold ($10–$20) typically yields 50–150 pours before edges start to look tired. So a $15 mold used 100 times adds $0.15 per piece. For acrylic or wood molds used for geode pours, they last much longer — 200+ uses is common — making the amortized cost negligible.
