How Many Candles From Wax Calculator
Take a 5 kg bag, lose 5% to the pot and the jug, and 4,750 g is what actually gets poured. At 180 g each that is 26 candles with 70 g left. Combine the 70 g into the next batch or pour it as a wax melt — something short of one candle is left over every time.

Formula
Candles = ⌊Wax on hand × (1 − Melt loss ÷ 100) ÷ Wax needed⌋
Fragrance is not in this count. Oil is added on top of the wax weight, so it does not reduce the number of candles, but it is a separate cost. The loss percentage depends on batch size: 5% is generous for melting 5 kg at once, but melting 500 g ten times leaves the same residue ten times over and pushes past 10%.
What to enter
| Input | Default | Accepted range |
|---|---|---|
| Wax on hand (g)The wax you have on hand, as the bag states it. | 5,000 | 1 and up |
| Wax needed (g)The wax to melt, by weight. | 180 | 1 and up |
| Melt loss (%)The share left in the pot and jug; melting in small batches raises it. | 5 | 0 ~ 20 |

Frequently asked questions
Q. How is How Many Candles From Wax Calculator calculated?
Candles = ⌊Wax on hand × (1 − Melt loss ÷ 100) ÷ Wax needed⌋ — Take a 5 kg bag, lose 5% to the pot and the jug, and 4,750 g is what actually gets poured. At 180 g each that is 26 candles with 70 g left. Combine the 70 g into the next batch or pour it as a wax melt — something short of one candle is left over every time.
Q. Can you walk through an example?
With Wax on hand 5,000g, Wax needed 180g, Melt loss 5%, the answer is Candles 26.
Q. What do I need to enter?
Enter Wax on hand, Wax needed, Melt loss. 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 Wax on hand (g) moves the answer to Wax on hand (g) 2,500 → Candles 13 and Wax on hand (g) 10,000 → Candles 52. 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?
Fragrance is not in this count. Oil is added on top of the wax weight, so it does not reduce the number of candles, but it is a separate cost. The loss percentage depends on batch size: 5% is generous for melting 5 kg at once, but melting 500 g ten times leaves the same residue ten times over and pushes past 10%.
