Resin art pricing calculator — free, no sign-up

Resin by the ounce, molds spread over the pours they survive, pigments, and the hours you actually spend mixing, pouring and sanding. Cure time is not labor, and this does not charge for it.

Materials

$14.41

Resin

$

Total mixed volume including what stayed in the cup. Roughly $0.45–0.95/oz depending on brand and volume — a $60 gallon works out near $0.47, premium food-safe brands and small bottles cost more.

Mold

$

Molds wear out. Typical life is anywhere from 50 to 300 pours — it is resin heat and wall thickness that decide it, not a fixed number. That range swings this line sixfold, so put in your own if you know it. Counts as $0.19 on this piece.

$

Mica, alcohol ink, dried flowers, glitter.

Gloves, cups and sticks

$

Single-use every pour, cheaper by the box. Counts as $0.72 on this piece.

Your time

$70.00
$

Count mixing, pouring, demolding and sanding. Curing time is not labor — you were elsewhere.

Overhead and markup

$

Ventilation, pressure pot, heat gun, workspace.

×2.2

Allows for the pours that fail. Some always do. ×2.2 is a 54.5% profit margin — not 120%, which is the mistake that quietly costs makers money.

Why this exists

Real comments from people asking this question. Every one links to the thread.

“Attach a dollar value to your time. Then find out your production costs. Amortizing mold costs is the hardest part since it is subjective.”
u/olderaccount, r/ResinCasting
“One thing I did at the beginning was measure how many grams/ounces of resin each mold uses.”
u/JMBGraves, r/ResinArt
“I have a bulletin board where I calculated out how much my brand of resin costs per ml.”
u/teyyannn, r/ResinCasting
“You calculate the cost of materials. Set a reasonable hourly wage for yourself and add 10-25% on top.”

What resin and epoxy pricing usually gets wrong

Only costing the resin that ended up in the piece

What stays in the cup was still bought and paid for. Measure the mixed volume, not the poured volume.

Treating molds as a one-off purchase

A mold has a working life measured in pours. Spread its cost across that life and every piece carries its fair share, instead of the first piece absorbing all of it and the rest pretending it was free.

Charging for cure time

Seventy-two hours of curing is not seventy-two hours of labor — you were doing something else. Charge for mixing, pouring, demolding and finishing. Long cure times justify a higher markup because they tie up your molds and your space, which is a different argument.

Ignoring the pours that fail

Bubbles, cloudiness, incomplete cures. Whatever your failure rate actually is, the pieces that survive have to carry it — and the markup is where that belongs, not the materials line.

Questions

Shouldn't I just multiply my material cost by three?
Sometimes that lands in the same place, and when it does it is a fine shortcut. It breaks in two directions. On a small fast item where your time dwarfs the materials, a multiplier underpays you badly. On an expensive-material piece that was quick to make, it overcharges for the material and undercharges for the skill. The multiplier is really a guess at labour plus overhead plus profit rolled into one number — so put your real hours in here, see what price comes out, and then check what multiple of your materials that turns out to be. If the two agree, use whichever you prefer. If they disagree, the arithmetic is the one telling the truth.
How do I price a piece with a failure rate?
Raise the markup rather than inflating the material cost. Materials should stay honest so you can see what a piece truly consumes; the markup is the right place for risk, and keeping them separate means you can tell when your process improves.
What about gloves, cups and stir sticks?
They are cheap individually and add up quickly. Buy them by the box, put the box cost in, and say how many pours a box covers — the calculator divides it down for you.
Should larger pieces cost proportionally more?
Materials scale roughly with volume, but labor does not scale as fast and risk scales faster. Price a large piece here properly rather than multiplying a small piece's price, or you will underprice the ones most likely to fail.
