Candle wax and fragrance oil calculator with cost per candle

Multiply the wax weight by the fragrance load. At a 6% load, one pound (454 g) of soy wax takes about 27 g, roughly 1 oz, of fragrance oil. At 10% it takes 45 g. Most soy waxes are rated for 6 to 10%; check your wax supplier's maximum and test burn before selling.

The formula

Fragrance weight = wax weight × fragrance load % · Wax weight = total fill ÷ (1 + load %)

  • Fill weight: the total weight of wax plus oil in one vessel, in grams.
  • Load: fragrance as a percentage of wax weight, the convention most suppliers use.
  • Cost per candle adds wick, vessel and label to the wax and oil.

How to calculate it step by step

  1. Weigh one vessel filled with wax to find the fill weight.
  2. Multiply by the number of candles for total fill.
  3. Divide total fill by one plus the fragrance load to get wax weight.
  4. Subtract wax from total fill to get fragrance oil weight.
  5. Price wax and oil by weight, add wick, jar and label per candle.
  6. Divide the batch cost by the number of candles.

Worked example

24 candles filled to 200 g at an 8% fragrance load, soy wax $6/kg and fragrance oil $70/kg.

Total fill24 × 200 g = 4,800 g
Wax4,800 ÷ 1.08 = 4,444 g
Fragrance oil4,800 − 4,444 = 356 g
Batch cost$26.67 + $24.89 + $45.60 = $97.16

Result. Each candle costs about $4.05 to make, so roughly $8.10 wholesale and $16.19 retail on the 2× and 4× rule.

Candle margin and wholesale pricing formula

A common rule for handmade goods is wholesale at twice total cost and retail at twice wholesale. The rule only works if labour and overhead sit inside total cost, so add your time per candle to the wick and jar line if you want it included.

Why fragrance testing loss matters

Test pours, sink marks and failed burns use real oil. Track them as their own batch so the cost per sellable candle reflects what the shelf actually lost. Makeable deducts every run from stock and warns you before the fragrance you need for an order runs out.

Common questions

How much fragrance oil per pound of soy wax?

About 1 oz (27 g) at a 6% load and 1.6 oz (45 g) at 10%. Never exceed the maximum load your wax supplier lists.

Is fragrance load a percentage of wax or total weight?

Most suppliers mean percentage of wax weight. This calculator uses that convention and shows the split of your total fill.

How do I calculate cost per candle?

Add wax cost, fragrance cost, and the wick, vessel, label and packaging for one candle. Divide batch costs by the number of candles poured.

What is a good wholesale price for candles?

Two times total cost is a common floor for wholesale, leaving the retailer room to double it for retail.

How many candles does a pound of wax make?

Divide 454 g by the wax weight per candle. A 200 g fill at 8% load uses 185 g of wax, so about 2.4 candles per pound.
