Who We Are
Hi, I'm Sarah Mitchell. I started making candles in 2022, initially as a hobby and quickly as a mild obsession. After testing over 50 wax and fragrance combinations — and ruining more than a few batches along the way — I realized that the biggest challenge for beginners isn't creativity. It's math.
Every candle making forum and Facebook group has the same questions: "How much fragrance oil do I need for an 8 oz jar?" and "Why is my candle tunneling?" The answers are usually buried in long threads, contradictory, or trying to sell you something.
That's why I built CandleCalc — a free, independent resource focused on helping beginners get the basics right from day one.
What Makes Us Different
No shop, no upsells. We don't sell wax, wicks, or fragrance oils. We have no financial incentive to recommend one product over another. When we mention specific brands (like Golden 464 or CandleScience fragrances), it's because they're what the community actually uses — not because we're getting a commission.
Independent and transparent. Our calculator runs entirely in your browser. We don't collect your data, track your calculations, or require an account. The math is open and explained in detail on each article.
How Our Calculator Works
The calculator uses published wax density values from manufacturer data sheets to convert your container volume into wax weight. Fragrance percentages are calculated as a share of total blend weight (the industry standard used by most wax manufacturers), not as a percentage of wax alone.
The density values we use (soy wax: 0.90 g/ml, beeswax: 0.96 g/ml, coconut blend: 0.88 g/ml) are averages across popular brands. Real-world variation is typically 1-2%, which is within the tolerance of most candle recipes.
All results are estimates. We strongly recommend weighing your ingredients with a digital scale accurate to 0.1g for consistent results.
How Our Content Is Created
Every article is fact-checked against at least two manufacturer sources (data sheets, safety guides, or official documentation from companies like Golden Brands, CandleScience, and the National Candle Association). We also test recommendations in our own candle making practice before publishing.
If you find an error or have a suggestion, please reach out. We take accuracy seriously and will update any article with better information.
