About Resin Calculators
Free tools helping resin crafters calculate exact amounts,
avoid expensive waste, and create professional projects.
Our mission
Resin crafting should be accessible, affordable, and frustration-free. We built Resin Calculators because we kept seeing the same problems in the resin community: ruined projects from running short mid-pour, wasted money from buying too much, and confusion about ratios, temperatures, and timing.
Every calculator on this site solves a real problem we've encountered or heard about from other crafters. The Small Batch Mixing Calculator exists because measuring tiny amounts accurately is hard. The Temperature Calculator exists because garage workshops have wildly different cure times than climate-controlled studios. The Waste Calculator exists because we've all bought gallon jugs that expired before we could use them.
Our goal is simple: Provide accurate, easy-to-use calculators that help you succeed with resin projects—whether you're making your first keychain or your tenth river table.
Why these calculators are free
We believe essential tools should be accessible to everyone. No sign-ups. No paywalls. No email collection. No data tracking beyond basic privacy-friendly analytics.
You can use every calculator on this site without creating an account or giving us your email address. We don't store your project data. We don't sell your information. The calculators work instantly in your browser with no app downloads or subscriptions required.
This will always be free. As the site grows, we may add premium features (like saved projects or bulk calculations), but the core calculators you see today will remain free forever.
How we make money (and why we're transparent about it)
Running a website costs money—hosting, domain, development time, and ongoing maintenance. We keep Resin Calculators sustainable through affiliate partnerships and display advertising.
Affiliate links
When you click product links on our Resin Supplies page or in calculator recommendations, we may earn a small commission if you make a purchase. This doesn't cost you anything extra— the price is the same whether you use our link or not.
We only recommend products we'd use ourselves or that solve real problems for resin crafters. We don't recommend junk just because it has a higher commission. If a product is overpriced or low-quality, we won't link to it regardless of potential earnings.
Our affiliate partnerships include:
- Amazon Associates (resin kits, molds, tools, safety gear)
- Direct resin brand programs (ArtResin, TotalBoat, etc. - when we join them)
- Craft retailer programs (Michael's, Joann, etc. - when available)
- Etsy affiliates (for specialty molds and supplies)
Display advertising
Once we reach sufficient traffic, we'll add display ads through networks like Ezoic or Mediavine. These are the banner ads you see on most content websites. We'll keep ads minimal and non-intrusive—no pop-ups, no auto-play videos, no ads that block content.
What we don't do
We don't sell your data. We don't require email sign-ups to access calculators. We don't gate content behind paywalls. We don't send spam. We don't track you across the internet. Our analytics are privacy-friendly and anonymous.
Our commitment to accuracy
Calculator accuracy is critical—using the wrong amount of resin can ruin expensive projects and waste hours of work. We take this seriously.
Every calculator on this site:
- Uses industry-standard formulas and conversion factors
- Is tested with real projects before publishing
- Includes appropriate buffers for waste and measurement error
- Shows calculations transparently (you can see how we arrived at results)
- Provides context and warnings for edge cases
All formulas are cross-checked against manufacturer data sheets, industry standards, and real-world pour results. If you find an error in any calculator, please contact us immediately. We'll investigate, fix it, and update the page within 24 hours.
Who we are
Resin Calculators is operated by resin crafters who understand the frustrations of imprecise measurements, wasted materials, and project failures from simple calculation mistakes. We've poured thousands of projects— from tiny jewelry pieces to full river tables—and learned these lessons the hard way.
We're not a corporation trying to sell you stuff. We're crafters building tools we wish existed when we started. When we recommend a product, it's because we've used it or heard consistently good things from the resin community, not because of commission rates.
The site launched in 2026 with 19 calculators covering the most common resin crafting needs. It exists because we wanted to help the resin community avoid the expensive mistakes we made when learning.
