Project cost

Most epoxy cost calculators only know one brand's kits. This one works for any product. Enter what you paid and the size of the pack, and it gives you the cost per litre, the cost of this pour and of each layer, and how many packs you need to buy. That also means you can compare two sellers on the same terms.

Notes

1. "Pack" means the combined A + B volume, so a "1 gallon kit" is 1 gallon of mixed epoxy. Some kits are named after the size of Part A alone, or sold by weight. If yours is, enter the real combined volume. The data sheet or the label on each bottle will have it.
2. The margin covers resin left in cups and on sticks, small leaks, and wood soak-in. There's no standard figure. Common advice runs from 5 to 15%. The exact-volume cost is shown on its own so you can see what the margin adds.
3. This covers resin only. Pigment, tape, mold release, sandpaper, and finish are extra.
