Question 1

How much wax do I need for an 8 oz candle?

Accepted Answer

An 8 oz (240 mL) jar of soy at 8 percent fragrance load needs about 199 g (7 oz) of wax and 17 g of fragrance oil. At 10 percent load it's 195 g of wax and 22 g of fragrance oil. The calculator above runs the maths for any vessel and batch.

Question 2

How much wax for a 4 oz candle?

Accepted Answer

A 4 oz (120 mL) jar of soy at 8 percent load needs about 99 g (3.5 oz) of wax and 9 g of fragrance oil. Halve the 8 oz numbers and you're within a gram.

Question 3

How much soy wax for a 10 oz candle?

Accepted Answer

A 10 oz (300 mL) jar of soy holds about 270 g of fill. At 8 percent load that's 248 g (8.75 oz) of wax and 22 g of fragrance oil.

Question 4

How much soy wax for a 12 oz candle?

Accepted Answer

A 12 oz (355 mL) jar of soy holds about 320 g of fill. At 8 percent load that's 294 g (10.4 oz) of wax and 26 g of fragrance oil.

Question 5

How much soy wax for a 16 oz candle?

Accepted Answer

A 16 oz (475 mL) jar of soy holds about 428 g of fill. At 8 percent load that's 394 g (13.9 oz) of wax and 34 g of fragrance oil.

Question 6

How do I calculate how much wax I need for candles?

Accepted Answer

Fill the empty vessel with water and weigh it (1 mL of water is 1 g). That number is total candle weight. Multiply by your wax's density factor (about 0.9 for soy and paraffin), then subtract the fragrance load. The calculator above does this for you and adds 10 percent headroom to the order quantity for melt-pot loss.

Question 7

How much soy wax flakes for an 8 oz candle?

Accepted Answer

Soy wax flakes and pellets weigh the same per fill, the flakes just take up more space in the bag. For an 8 oz jar at 8 percent load you need 199 g (7 oz) of flakes by weight, not volume.

Question 8

How much wax is lost to the melt pot?

Accepted Answer

Plan for 5 to 10 percent loss to pot residue, top-off pours and spillage. The suggested order weight above includes 10 percent headroom by default.

Question 9

Does wax density really matter?

Accepted Answer

Yes. Soy and paraffin are roughly 0.90 g/mL, beeswax is 0.96, gel is 0.85. Using the wrong density on a large batch can leave you 50 to 100 g short per batch.

Question 10

How much does wax cost for candles?

Accepted Answer

At small-batch volumes soy wax runs roughly £7–£10/kg, paraffin £5–£8/kg, beeswax £20–£30/kg, and coconut-soy blends £11–£16/kg. Switch the currency picker in the header and prices reconvert live. The recipe builder pulls the same numbers when costing a blend.
