Why Candle Math Matters

One of the most common reasons new candle businesses fail is poor calculation. Overestimating wax leads to waste, while underestimating costs destroys your profit margins. Furthermore, improper fragrance loads (calculating by volume instead of weight) can create unsafe candles that "sweat" or catch fire.

Candles Molds provides this suite of free candle making calculators to replace the guesswork with precision. Our formulas are based on industry standards used by professional chandlers, ensuring your production process is consistent, safe, and profitable.

Frequently Asked Questions

To find out exactly how much wax and fragrance oil you need, you must first determine your container's total volume weight and your desired fragrance load percentage (usually 6% to 10%). Instead of doing complex math by hand, you can use our free Wax & Fragrance Calculator above to get the exact gram or ounce measurements instantly.
The industry standard fragrance load is between 6% and 10%. For exactly 1 pound (16 oz) of wax, a 6% load requires about 1 ounce of fragrance oil, while a 10% load requires 1.6 ounces. Always check your specific wax manufacturer's guidelines, and use our Fragrance Load Calculator to ensure your candles are safe and won't sweat.
Wick size is determined primarily by the inside diameter of your container and the density of the wax you are using (e.g., Soy, Paraffin, or Beeswax). Simply measure the inside width of your jar and input it into our Wick Size Estimator to find your perfect starting cotton or wooden wick size to prevent tunneling.
A profitable candle business requires calculating the exact Cost of Goods Sold (COGS), which includes your wax, vessel, wick, fragrance, warning label, and labor time. Once you have your total cost to make one candle, multiply it by 2 for wholesale pricing, and by 4 for retail pricing. Use our Pricing & Profit Calculator to map out your margins easily.
