Price per piece for a target margin
US Etsy fees: 6.5% transaction and 3% + $0.25 processing on item + shipping, $0.20 listing fee per piece sold. Target-margin prices assume a one-piece order without Offsite Ads.
Price resin by weight, not by kit
Resin kits are sold by volume or weight, but projects use very different amounts. Weigh the mixed resin for one piece, including what stays in the cup. Multiply by your price per kg and you have the real material cost.
Silicone molds wear out. If a $20 mold lasts 25 pours, every piece carries $0.80 of mold cost; leaving it out overstates profit on every sale.
Worked example with the default inputs
| Line | Normal sale | Offsite Ads sale (15%) |
|---|---|---|
| Buyer pays ($28.00 + $0.00 shipping) | $28.00 | $28.00 |
| Etsy fees | −$3.11 | −$7.31 |
| Cost per piece | −$12.94 | −$12.94 |
| Postage + packaging | −$5.80 | −$5.80 |
| Profit (margin) | $6.15 (22.0%) | $1.95 (7.0%) |
For a 40% margin on a one-piece order with these costs, the price would need to be about $37.99. The defaults are illustrative; replace them with your own supplier prices and timed production.
Where the margin goes
Sanding, doming and demolding are hands-on minutes that add up faster than resin. A set of four coasters shares one postage label, so compare a single piece with a set using the quantity field or the bundle pricing calculator.
