What is candle wax & fragrance load calculator?
A candle wax calculator estimates how much wax and fragrance oil to prepare for a batch. Container volume is not the same as wax weight, so the calculator applies a density estimate before calculating fragrance load.
How to use this calculator
- Enter filled container volume.
- Select wax type.
- Enter fragrance load recommended for your wax and oil.
- Multiply by the number of candles in the batch.
How is it calculated?
Formula
wax weight = container volume x wax density; fragrance = wax weight x fragrance load What The Constants Mean
- Soy wax density (0.86): Planning estimate for ounces by weight per fluid ounce of container volume.
- Percent divisor (100): Converts a user-entered percent into a decimal multiplier.
Six 8 fl oz soy candles at 8% fragrance load need about 41.28 oz wax and 3.3 oz fragrance oil.
Common mistakes
Do not assume every 8 fl oz jar holds 8 oz of wax by weight. Fragrance load limits depend on wax, fragrance oil, wick, vessel, and testing.
FAQ
Is fragrance load based on wax weight?
Yes. Fragrance oil is commonly calculated as a percentage of wax weight.
Can I use any fragrance percentage?
No. Follow the wax and fragrance supplier's tested limits.
Does wick size come from this calculator?
No. Wick sizing requires burn testing with your vessel, wax, and fragrance.
Why is wax density estimated?
Different waxes and temperatures vary, so this is a planning estimate.
