Candle Fragrance Load Calculator
Fragrance load is a percentage of the wax, not of the finished candle. Eight per cent of 500 g is 40 g of oil, making a 540 g batch. Every wax has a ceiling it can hold; past that the oil sits on the surface instead of binding in.

Formula
Fragrance oil = Wax needed × Fragrance load ÷ 100
Weigh fragrance oil rather than measuring it by volume — its density is not water's, so millilitres put you several per cent out. Follow the wax's stated adding temperature, not the oil's.

Frequently asked questions
Q. How is Candle Fragrance Load Calculator calculated?
Fragrance oil = Wax needed × Fragrance load ÷ 100 — Fragrance load is a percentage of the wax, not of the finished candle. Eight per cent of 500 g is 40 g of oil, making a 540 g batch. Every wax has a ceiling it can hold; past that the oil sits on the surface instead of binding in.
Q. Can you walk through an example?
With Wax needed 500g, Fragrance load 8%, the answer is Fragrance oil 40g.
Q. What do I need to enter?
Enter Wax needed, Fragrance load. The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only Wax needed (g) moves the answer to Wax needed (g) 250 → Fragrance oil (g) 20 and Wax needed (g) 1,000 → Fragrance oil (g) 80. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
Weigh fragrance oil rather than measuring it by volume — its density is not water's, so millilitres put you several per cent out. Follow the wax's stated adding temperature, not the oil's.
