🌿 Fragrance Load Calculator
Enter your wax weight and the fragrance percentage you want to use to see exactly how much oil to add — in ounces and grams — plus the total batch weight, so every candle smells the way you intend.
🧮 Fragrance Oil For Your Batch
What is a Fragrance Load Calculator?
It converts a fragrance percentage into the precise amount of oil to weigh out. Because load is expressed against the wax weight, this tool multiplies your wax by your chosen percentage and reports the oil in ounces and grams alongside the finished batch weight — no fiddly mental maths at the scale.
Use it to hit a consistent scent throw batch after batch, stay within your wax's safe maximum, and scale a recipe without guesswork. Fragrance behaviour still depends on your wax, oil, wick, and cure time, so treat the result as your starting dose and test before scaling up.
❓ Frequently Asked Questions
How much fragrance oil should I add to candle wax?
Fragrance load is measured as a percentage of the wax weight, not the total. A typical range is 6–10%, with 8% a common starting point. Enter your wax weight and percentage and this calculator gives the exact oil to add in both ounces and grams.
What is the maximum fragrance load?
Most soy waxes are rated to hold up to about 10% fragrance, but the safe maximum varies by wax and by oil. Always follow the wax and fragrance manufacturer's stated maximum — going over it causes the oil to seep out, ruins the burn, and creates a fire-safety risk.
Is fragrance load based on wax weight or total weight?
It's based on the wax weight. If you have 16 oz of wax at 8%, you add 1.28 oz of fragrance for a 17.28 oz batch. Calculating on the total instead would under-dose the candle, so this tool always uses the wax weight as the base.
Why does my candle have a weak scent throw?
Common causes are too little fragrance, not enough cure time, or a wick that's too small to melt a full pool. Try dosing toward the top of the safe range, giving the candle a proper cure, and confirming your wick size with a test burn.
