How the calculator works
Enter your floor area or its length and width. The calculator multiplies the area by the number of coats, divides by your product's coverage rate, then adds your waste allowance. Unit pricing uses that recommended quantity; kit pricing rounds up to whole kits.
Find your coverage rate
Use the coverage rate listed by your epoxy manufacturer for the product and application you plan to use. Surface texture and application method can change real coverage. The calculator does not assume a universal rate.
Coats and waste
Enter the number of coats required by your product and floor plan. Waste covers material left in containers, spills, uneven surfaces, and other project losses. Adjust the allowance for your job.
Material cost vs installed cost
Epoxy Material Cost covers only the epoxy quantity or full kits. Add primer, top coat, flakes, surface preparation, labor, and other local charges when they apply. Actual prices vary by product, location, floor condition, preparation requirements, labor rates, and project complexity.
Frequently asked questions
How much does epoxy flooring cost?
Multiply the epoxy quantity by your product price, then add any preparation, labor, primer, top coat, and other charges for your project. Use local quotes instead of a fixed national average.
How much epoxy do I need for my floor?
Divide your total coat area by the manufacturer's coverage rate, then add a waste allowance. Total coat area is floor area multiplied by the number of coats.
How do I calculate cost per square foot?
Divide the estimated total project cost by the floor area. This tool shows cost per sq ft in US customary units and per m² in metric units.
How many gallons do I need?
Enter floor size, number of coats, and your product's square feet per US gallon. In kit mode, the calculator also shows the whole kits and purchased volume required.
How much does it cost to epoxy a garage floor?
Choose a garage example to fill dimensions, then replace them with your actual measurements. Enter product coverage and your local material and labor prices to estimate the cost.
