🌸 Fragrance Load Percentage Calculator

Fragrance load is the weight of fragrance oil as a percentage of your wax weight. Enter your amounts to calculate the percentage — always check your specific wax and fragrance oil supplier's recommended maximum, which is commonly in the 6-10% range but varies by product.

Always check your wax and fragrance supplier's maximum recommended load for your specific products.

Oil as a share of wax

Fragrance load is weighed against the wax alone, never against the finished candle:

load % = fragrance oil weight / wax weight × 100
oil needed = wax weight × target load

The defaults, 48 g of oil in 600 g of wax, come out at 8.00 percent. Run it the other way and 600 g of wax at a 6 percent target needs 36 g of oil, at 10 percent 60 g. Everything is weighed, not measured by volume — fragrance oils differ in density, so millilitres will not give you a repeatable load.

Most container waxes are rated to hold 8 to 10 percent, and 8 is the usual starting point. The maximum belongs to the wax you bought, so check its data sheet rather than the range.

Past the wax's rated load the oil stops binding. It beads on the surface, sinks into a layer at the base of the jar and can feed the flame, which is a fire risk, not a stronger scent. If the throw is weak, cure the candle a week or two longer and try a larger wick before adding oil.

Frequently asked questions

What is a standard fragrance load for candles?

8 percent of wax weight. Suppliers usually quote a 6 to 10 percent range, with 6 for delicate oils and 10 as the ceiling for most soy and coconut container waxes.

How much fragrance oil goes into 600 g of wax?

48 g at 8 percent, which is what the calculator loads by default. Use 36 g for a 6 percent load and 60 g for 10 percent.

Is the percentage of the wax or of the whole candle?

Of the wax, which is the trade convention this tool follows. 48 g of oil in 600 g of wax is 8 percent by that measure but 7.41 percent of the 648 g poured, so a supplier quoting on total weight is not talking about the same number.
