Formula
Gallons = area × coats ÷ coverage × (1 + waste ÷ 100).
The result rounds up to a whole gallon on a second line because leftover liquid is cheaper than a dry spot. The cost uses the unrounded gallons times your price.

Epoxy calculator for gallons and flooring cost
This epoxy calculator divides the floor area by the square feet one gallon covers in one coat, then multiplies by coats and waste. A resin calculator uses the same coverage line. The price you enter turns it into an epoxy flooring cost calculator for material only.

Planning estimate from the numbers you enter. Coverage, density, waste and price are assumptions, not a supplier quote or an engineering specification.
How it works
Coverage comes from the kit, not from a universal thickness.
Epoxy and resin kits print a coverage, often as square feet per gallon at a stated thickness. This page uses that number. It does not convert mils unless you have already turned the mils into square feet per gallon. Gallons equal area times coats, divided by coverage, times one plus the waste percent. Waste covers mixing loss and a rough slab. Cost is gallons times your price per gallon. Labor, grinding, and crack repair are not in that price. If the kit is sold as a two-part unit that covers a stated area, set the coverage so one unit matches that area and read the gallons as units.

Example
400 square feet, 100 square feet per gallon, two coats, 10 percent waste.
The order is 8.80 gallons, which rounds to 9. At $80 per gallon the material is $704.00. If the resin calculator coverage on your kit is different, replace the 100. Two coats are already in the 8.80.

Tips
A porous slab drinks the first coat.
The printed coverage assumes a prepared surface. Add waste, or lower the square feet per gallon, when the concrete is open. The epoxy flooring cost calculator line will follow. It still will not include the prep labor.

Equipment
Grinders and the mix are different purchases.
Floor prep equipment in the $15,000 to $2 million range can go through a Dengaro application. The gallon count stays a material estimate.
Important questions
Know what to expect.
How is a resin calculator different from epoxy?+
On this page it is not. Both are coverage times coats, plus waste. Enter the square feet per gallon, or per kit, from the resin you are using.
What does the epoxy flooring cost calculator leave out?+
Labor, diamond grinding, patching, and taxes. The cost is gallons times the price per gallon you type.
Can I enter a kit instead of a gallon?+
Yes. If one kit covers 200 square feet, put 200 in the coverage field and read gallons as kits. Keep the price as the price per kit.
Does thickness get a separate field?+
No. Thickness is already inside the coverage number the manufacturer prints. Use that number rather than a second thickness guess.
