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

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.

How much wax for a 4 oz candle?

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.

How much soy wax for a 10 oz candle?

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.

How much soy wax for a 12 oz candle?

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.

How much soy wax for a 16 oz candle?

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.

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

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.

How much soy wax flakes for an 8 oz candle?

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.

How much wax is lost to the melt pot?

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.

Does wax density really matter?

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.

How much does wax cost for candles?

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.

One 240 ml straight-sided jar, soy wax, 8 percent fragrance load, pouring 12 candles.

Finished fill per candle
240 ml of usable volume × 0.9 g/mL soy density = 216 g of finished fill.
Split fill into wax and fragrance
Wax = finished fill ÷ 1.08, so 216 g ÷ 1.08 = 200 g of wax. Fragrance = 216 g minus 200 g = 16 g.
Scale to the batch
200 g × 12 candles = 2.4 kg of wax and 192 g of fragrance oil.
Add melt-pot headroom
10 percent on the wax figure gives an order weight of 2.64 kg.

Answer

Order 2.64 kg of soy and 192 g of fragrance oil for 12 jars.

Headroom covers pot residue and top-off pours. Weigh your own empty vessel with water if the jar is tapered.

Tell us your vessel volume and how many candles you're pouring. Wax weight is calculated from volume × the chosen wax's density. We return total wax per batch (with the fragrance load already deducted) and a suggested order weight that accounts for melt-pot loss.
