Candle Fragrance Calculator: How Much Fragrance Oil per Candle?
Work out exactly how much fragrance oil your candles need. Enter your wax weight and fragrance load, and this free calculator from Aromya, a fragrance oil manufacturer in Delhi, gives you the grams of fragrance oil per candle and for the whole batch.
How the calculation works
Candle makers measure fragrance load as a percentage of the wax weight. The formula is:
Fragrance oil (g) = wax weight (g) × fragrance load (%) ÷ 100
Example: 200 g of soy wax at 8% needs 200 × 8 ÷ 100 = 16 g of fragrance oil. For 50 candles that is 800 g, so a 1 kg bottle covers the batch.
Recommended fragrance load by wax
| Wax | Typical fragrance load | Notes |
|---|---|---|
| Soy wax | 8% to 10% | Most popular for container candles; let candles cure for 1 to 2 weeks. |
| Paraffin wax | 6% to 12% | Strong hot throw; check your wax supplier's maximum. |
| Coconut / coco-soy | 8% to 12% | Creamy finish, good scent throw. |
| Gel wax | 3% to 5% | Use fragrance oils suitable for gel to avoid cloudiness. |
| Beeswax | 3% to 6% | Has its own honey scent, so it holds less fragrance. |
These are typical ranges, not rules. Always check the maximum load your wax manufacturer recommends, test burn a few candles with your wick and jar, and stay within the IFRA limit for candles shown on your fragrance oil's IFRA certificate.
Tips for a stronger scent throw
- Add fragrance oil at the temperature your wax supplier recommends (often around 80 to 85 °C for soy), then stir gently for 2 minutes.
- Let soy candles cure for at least 7 days before testing the scent.
- More fragrance is not always better: going over the wax's limit can cause sweating, poor burning and soot.
- Choose the right wick size for your jar diameter; a wick that is too small will not release the scent.
