Fragrance load and fragrance content
Fragrance load is the weight of oil divided by the weight of the wax alone. Fragrance content is the weight of oil divided by the weight of wax and oil together. The same candle therefore has a smaller content than load, and the two are linked: content equals load divided by one plus load.
Most recipes and suppliers state a load, but some state a content, so check which one a number means before you use it. A recipe that says two hundred grams of wax at ten percent means twenty grams of oil as a load, but twenty-two grams of oil in a two-hundred-and-twenty-gram fill as a content.
The most oil a wax can hold is a supplier's figure and it differs between suppliers and between waxes, so this site gives none: enter yours and the calculator tells you when you are above it. Weigh the oil on a scale. Whether a particular wax and oil behave well together is something only a small test candle shows.
Chart: grams of fragrance oil by wax weight and load
Each cell is the oil to add to the wax weight in its row at the load in its column, as a share of the wax alone. To use a content instead, take the calculator's total-weight mode.
