Batch Candle Wax Calculator
Take the weight one vessel needs and multiply by the count. The figure assumes filling to nine tenths.
Your numbers
Wax needed

Spare

Formula
Wax needed = Container volume × 0.9 × Candles × Wax density
Melt about 5% extra. Some always clings to the pouring jug, and coming up short on the last candle means melting a whole second batch for it.
What to enter
| Input | Default | Accepted range |
|---|---|---|
| Container volume (mL)What the vessel holds; filling it with water is the accurate way. | 200 | 1 and up |
| CandlesHow many you are pouring in one batch of identical vessels. | 12 | 1 and up |
| Wax density (g/cm³)Grams per cm³ of wax — soy near 0.9, paraffin a little more. | 0.9 | 0.5 ~ 1.2 |

Frequently asked questions
Q. How is Batch Candle Wax Calculator calculated?
Wax needed = Container volume × 0.9 × Candles × Wax density — Take the weight one vessel needs and multiply by the count. The figure assumes filling to nine tenths.
Q. Can you walk through an example?
With Container volume 200mL, Candles 12, Wax density 0.9g/cm³, the answer is Wax needed 1,944g.
Q. What do I need to enter?
Enter Container volume, Candles, Wax density. 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 Container volume (mL) moves the answer to Container volume (mL) 100 → Wax needed (g) 972 and Container volume (mL) 400 → Wax needed (g) 3,888. 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?
Melt about 5% extra. Some always clings to the pouring jug, and coming up short on the last candle means melting a whole second batch for it.
