Epoxy Cost Calculator
Enter the price and size of your resin kit and how much epoxy your project needs. You will see the cost per unit, the cost of the project and how many kits to buy.
How the calculation works
Cost per unit = kit price ÷ kit size. Project cost = cost per unit × amount needed. Kits needed = amount needed ÷ kit size, rounded up.
Example: a 1 gallon kit at $89 costs $0.70 per US fl oz. A project that needs 40 fl oz costs about $27.81 in resin, but you must buy one whole kit for $89.
To find out how much epoxy your project needs, try the tabletop, river table or mould calculators.
The result covers resin only, not pigments, tools or safety equipment.
Frequently asked questions
How do I compare epoxy prices?
Divide the price by the volume in the same unit for every kit. The cost per fluid ounce (or per litre) is what matters, not the price of the box. Larger kits are usually cheaper per ounce.
Why is the cost of the kits higher than the cost of the project?
Resin is sold in whole kits, so you pay for the leftover. The calculator shows both numbers so you can decide whether to buy a bigger kit or adjust the project.
Does the kit size include both Part A and Part B?
Usually yes. Kit sizes are normally the total of resin plus hardener. Check the label to be sure, and enter the total mixed volume.
What other costs should I add?
Pigments, mixing cups, stir sticks, gloves, a respirator, mould release and sandpaper or polish all add to the real cost of a project.
