Example calculations

Small market batch
12 candles in 9 oz jars at 8% fragrance load
A practical Etsy-style batch where wax, fragrance, and wick choice all need to be planned before pouring.
Result: The calculator backs out the wax weight after accounting for fragrance load so the batch mix is closer to a real pour plan.
Holiday sampler tins
24 candles in 4 oz tins at a 9% load
Smaller containers often make cost-per-candle look better, but fragrance oil can still move the batch economics.
Result: Tiny vessels keep fill weight down, though fragrance-heavy formulas can still be expensive.
Large vessel test run
6 large jars with a more restrained 6% load
Useful for bigger vessels where burn testing and wick band selection become a larger part of the planning question.
Result: Large jars push more wax per unit and often move into larger single-wick or double-wick territory.
How the candle batch estimate works
The calculator starts with a common container-size preset that includes an approximate finished fill weight and a practical wick-size starting band. It multiplies that fill weight by the number of candles in the batch.
Because fragrance load is usually expressed as a percentage of wax weight, the calculator backs the wax amount out of the final fill weight rather than simply adding fragrance on top. Material cost is then based on wax price per pound and fragrance price per ounce.
Candle making FAQs
Use the result to plan pours and raw-material ordering, then validate wick choice with burn tests.
Why does wax weight go down when fragrance load goes up?
Because fragrance oil takes up part of the total fill weight. If the finished candle weighs the same, adding more fragrance means the wax portion of the blend has to come down.
Is the wick recommendation exact?
No. It is a starting band for common container sizes, not a substitute for burn testing. Wax type, fragrance, dye load, jar geometry, and room conditions can all change the final wick choice.
Does this include jars, labels, lids, or labor?
Not in the base result. This version focuses on wax and fragrance oil material cost only, so it is best used as a quick batch-mixing and raw-material estimate.
