Epoxy Calculator and Resin Project Planner
Calculate exactly how much epoxy resin you need — with waste, seepage, layer count, Part A / Part B split, cost, and product-fit guidance built in.
Choose the calculator that matches the real job
The fastest way to get a trustworthy estimate is to start from the actual project type. River tables, deep pours, coatings, floor jobs, and void fills do not share the same measurement logic or product constraints.
River Table Calculator
Use quick mode or segment mode for live-edge rivers, plus seepage, seal-coat, and cost planning.
Open pageDeep Pour Calculator
Plan thick casts with layer guidance, staged lifts, and deep-pour product fit.
Open pageCoverage Calculator
Use surface area and coat thickness for tabletops, bar tops, and countertop finishes.
Open pageWhat every estimate gives you
The goal is not a raw number. The goal is a usable purchase plan you can compare against real kits and product limits.
- Raw volume and recommended order quantity shown side by side.
- Waste, seepage, seal-coat, and overage explained instead of hidden.
- Part A / Part B split and approximate project cost for faster buying decisions.
- Layer guidance for deep-pour and thick-cast scenarios.
Popular decisions people make before buying epoxy
Search traffic around epoxy is not only looking for a formula. People also want to know how much extra to buy, how to measure irregular rivers, and when they need deep-pour resin instead of a top coat.
