Epoxy Calculator – Accurate Resin Volume & Cost Estimation

Whether you’re working on a river table, countertop pour, bar top, or clear coat, getting your epoxy volume calculation right is critical to avoiding waste or costly shortages. That’s why US Kitchen Cabinet created a smart, easy-to-use Epoxy Calculator to help you plan every pour with precision.

What Is the Epoxy Calculator?

The Epoxy Calculator by US Kitchen Cabinet is a resin planning tool that lets you:

• Calculate the exact volume of epoxy needed for any rectangular or circular surface
• Add a waste buffer (default is 5%)
• Convert results into litres and US gallons
• Estimate total cost based on your resin price per litre or gallon

How the Epoxy Calculator Works

The tool follows a simple 3-step process designed to work just like our other project calculators.

1. Choose Your Shape

• Rectangle: For tabletops, countertops, slabs, or boxes
• Circle: Ideal for bar tops, resin clocks, or round pours

2. Enter Your Dimensions

Use any unit that’s convenient:

• cm, m, inches, feet, or feet + inches
• Enter length & width (for rectangles) or diameter (for circles)
• Specify epoxy thickness in mm, cm, in, or ft for top coats or deep pours

3. Add Your Waste Factor

• The default is 5% to cover mixing losses, over-pours, and edge coverage
• You can increase or decrease based on project type or experience

4. Optional: Enter Epoxy Price

• If you know the cost per litre or gallon, the calculator will show your total estimated material cost

What the Calculator Outputs

After hitting “Calculate,” you’ll get:

Output	Description
Total Volume (L)	Resin needed in litres, with waste factor included
Total Volume (gal)	Resin needed in US gallons, with waste included
Total Cost	Optional – shown only if you provide price per litre or gallon

All unit conversions and rounding are handled in the background, so you can focus on the project not the math.

Why Use an Epoxy Calculator?

• Avoid Resin Shortage: Don’t stop mid-pour due to underestimation
• Reduce Waste: Only buy what you need – especially with premium resins
• Save Money: Estimate budget before you pour
• Plan Large Pours Efficiently: Perfect for epoxy tables, river boards, or art pieces

People Also Ask

How much epoxy do I need for a 10 sq ft table?

It depends on the thickness of your pour. For example, a 10 sq ft surface with a 1/8″ coat needs ~1.25 gallons (4.75 L). The calculator does this math for you instantly.

How do I calculate epoxy volume for a river table?

Choose Rectangle, enter dimensions for the river cutout area, and select your desired pour depth. The calculator gives you total volume plus waste.

What is the waste factor in epoxy resin?

A standard 5% waste accounts for leftover resin in mixing cups, container walls, over-pour, and sanding loss. You can change it based on your project experience.

Can I use this calculator for deep pour epoxy?

Yes just set the thickness field to your actual pour depth (e.g., 2″ for deep-pour). Always follow your resin’s max depth per layer.

Pro Tip:

Measure your mold dimensions carefully and always round up slightly for irregular edges or curved shapes. If you’re doing a live edge or uneven pour, increase your waste factor to 8 – 10%.

Plan Your Next Pour with Confidence

The US Kitchen Cabinet Epoxy Calculator takes the guesswork out of every resin project whether it’s a thin tabletop coat or a deep river pour. You’ll know exactly how much resin you need, how much it will cost, and how to prepare for success.
