When to use this calculator
Fragrance oil weight is wax weight times load percentage. Cost is that weight times your oil price. Optional candle count spreads a bottle across units.
How this calculator works
How we calculate this
- Fragrance oz = wax oz × (load / 100)
- Oil cost = fragrance oz × price per oz
Example
Example: 16 oz wax at 8%
1.28 oz of oil. At $1.85/oz that is $2.37 — often more than the wax line.
- Changing load from 6% to 10% moves cost more than a small wax price change.
How much should I charge?
This is an ingredient cost. Fold it into the candle pricing calculator.
Pricing tips
- Stay inside the oil manufacturer’s recommended load.
- Weigh oil; do not measure only in droppers for cost.
Common mistakes
- Calculating load on vessel size instead of wax weight.
- Using a retail 1 oz tester price for a bulk production quote without updating later.
FAQ
How much fragrance oil do I need for a candle?
Multiply wax weight by your load percentage. An 8% load on 16 oz of wax is 1.28 oz of oil. Confirm the load is appropriate for your wax and oil.
