How to Calculate DIY Floral Resin Coaster Cost
Pressed flower resin coasters are one of the most popular handmade items on Etsy — and for good reason. A single silicone mold and a bottle of epoxy resin can produce dozens of coasters, each uniquely framed around dried lavender, wildflowers, or botanicals you press yourself. But the material costs can creep up quickly if you do not track them, and underpricing your work is the fastest way to burn out on a craft you love.
This calculator breaks down every input — resin per ounce, mold amortization, dried florals, and pigment — into a true cost-per-coaster figure, then compares it to what similar sets sell for on Etsy so you can make an informed decision about whether to DIY or buy.
What Goes Into a Floral Resin Coaster
- Epoxy resin — The biggest cost by volume. Two-part casting resins run $0.75–$1.50 per oz for mid-range brands like ArtResin or Let's Resin. A 4-inch round coaster needs roughly 0.5–1 oz of mixed resin. Buying in larger kits (32 oz and up) typically cuts the per-oz cost by 20–35% versus small starter sets.
- Silicone mold — A quality 4-pack coaster mold costs $10–$25 and yields 50–150 pours before edges begin to tear. Divide the mold price by your expected uses to get the amortized cost per coaster (often just $0.10–$0.25).
- Dried florals and botanicals — This is where floral coasters diverge from plain resin. You can press your own flowers for near-zero cost (a flower press runs $10–$20 and lasts years) or buy pre-dried botanicals. Ready-to-use dried wildflower packs cost $8–$20 for enough flowers to make 12–20 coasters, putting floral cost around $0.50–$1.50 per coaster depending on how densely you arrange them.
- Pigment, alcohol ink, or UV dye — Subtle tinting is optional but popular. A small bottle of resin pigment ($5–$12) goes a long way, adding roughly $0.10–$0.50 per coaster. UV-resistant pigments help prevent yellowing over time.
Pressing Your Own Flowers vs. Buying Pre-Dried
Pressing your own flowers from the garden is the most cost-effective route — the main investment is time (2–4 weeks to dry under a heavy book or flower press) and a little planning ahead. Pre-dried botanicals from craft stores or Etsy sellers offer instant convenience but at a price premium. Either way, fully dried flowers are essential: any residual moisture trapped in resin will cause cloudiness or bubbling that ruins the piece.
Pricing Floral Resin Coasters for Selling
A standard handmade goods pricing formula is materials × 3–4 for retail. At $2–$4 in materials per coaster, that puts a single coaster at $6–$16 retail, or a set of four at $24–$64 — well within the $28–$55 range you commonly see on Etsy for handmade floral resin sets. If you sell on Etsy, remember to account for their 6.5% transaction fee and 3% payment processing before setting your final price.
Labor is where the real difference lies. Floral resin coasters take more hands-on time than plain pours because you need to arrange the botanicals carefully, often layering resin in two pours (a base layer, then a top coat) to suspend the flowers properly. Budget 20–40 minutes of active time per coaster. At $18/hr that is $6–$12 in labor per coaster — more than the material cost. Price accordingly if you plan to sell sustainably.
DIY vs. Buying on Etsy
If you want a single set of four coasters and have no supplies on hand, buying on Etsy is almost always cheaper than buying a full resin kit just for one batch. The math shifts in favor of DIY when you make multiple batches, plan to sell, or want specific flower varieties not available in pre-made sets. The calculator above shows your break-even point clearly.
