Epoxy Calculator
Epoxy projects—whether countertops, river tables, floors, or deep pours—require precise material calculation. Too little epoxy can ruin a project, while too much leads to unnecessary cost and waste. That’s where an Epoxy Calculator becomes an essential tool for DIYers, woodworkers, contractors, and epoxy artists.
This Epoxy Calculator helps you quickly determine total epoxy volume, resin and hardener amounts, and even estimated cost, based on your project dimensions, number of coats, waste factor, and mix ratio. With support for both imperial and metric units, it ensures accuracy for projects of all sizes.
What Is an Epoxy Calculator?
An Epoxy Calculator is a smart estimation tool that calculates how much epoxy resin and hardener you need for a specific project. By entering your project dimensions, thickness, and coating layers, the calculator instantly provides:
- Total epoxy volume required
- Resin and hardener quantities based on mix ratio
- Waste-adjusted epoxy amount
- Estimated project cost
This eliminates guesswork and helps ensure smooth application and professional-quality results.
Supported Project Types
This calculator is designed to handle a wide range of epoxy applications, including:
- Countertops & Table Tops
- Floor Coatings
- River Tables
- General Surface Coatings
- Deep Pour Casting Projects
Each project type benefits from accurate volume estimation, especially when working with expensive epoxy materials.
How to Use the Epoxy Calculator (Step-by-Step)
Using the Epoxy Calculator is simple and beginner-friendly:
Step 1: Select Project Type
Choose the type of epoxy project you’re working on, such as a countertop, floor, or river table.
Step 2: Choose Measurement Unit
Select either:
- Inches / Feet (Imperial)
- Centimeters / Meters (Metric)
The calculator automatically adjusts calculations based on your selection.
Step 3: Enter Dimensions
Input:
- Length
- Width
- Thickness (or depth of pour)
Make sure measurements are accurate for best results.
Step 4: Set Number of Coats
Enter how many epoxy layers you plan to apply. Multiple coats increase total volume.
Step 5: Add Waste Factor
A waste factor (usually 5–15%) accounts for spills, mixing loss, and uneven surfaces.
Step 6: Choose Mix Ratio
Select your epoxy system’s resin-to-hardener ratio (e.g., 1:1, 2:1, 3:1).
Step 7: Calculate
Click Calculate to instantly see your epoxy requirements, resin/hardener split, and estimated cost.
Example Calculation
Project: River Table
- Length: 60 inches
- Width: 24 inches
- Thickness: 1.5 inches
- Number of Coats: 1
- Waste Factor: 10%
- Mix Ratio: 2:1
Results:
- Total epoxy needed (gallons)
- Resin amount based on ratio
- Hardener amount based on ratio
- Estimated material cost
This ensures you purchase exactly what you need—no more, no less.
Why Accurate Epoxy Calculation Matters

- Incomplete coverage
- Visible seams or bubbles
- Inconsistent curing
- Wasted materials and money
Using an epoxy calculator helps you:
- Maintain proper mix ratios
- Reduce costly mistakes
- Improve finish quality
- Save time and budget
