Candle Wax Calculator
Free candle wax calculator: water weight × 0.86 gives wax per container, fragrance oil at 6–10% load, and cost per candle. An 8 oz tin takes 6.88 oz.
Enter two numbers in the calculator above — how many containers you’re pouring and how much water each one holds at the fill line, weighed in ounces — and it returns the wax you need in ounces, pounds, and grams. It uses the standard water-weight conversion: wax weighs about 86% of the same volume of water, so an 8 oz tin takes 6.88 oz of wax, not 8. Set your fragrance load (default 8%, the middle of the 6–10% range most container waxes are designed for) and it computes fragrance oil weight the correct way, as a percentage of wax weight — it doubles as a fragrance load calculator. Add your wax price per pound and fragrance price per ounce and you get a materials cost per candle before you melt anything. The 0.86 factor is an industry average that holds within a few percent for soy, paraffin, and coconut blends; beeswax is the exception — its specific gravity is about 0.96, so multiply water weight by 0.95–0.96 instead (an 8 oz-water tin takes about 7.7 oz of beeswax).
How much wax do I need for an 8 oz candle?
6.88 oz of wax. An 8 oz container holds 8 oz of water by weight at the fill line, and wax weighs about 86% as much as the same volume of water, so 8 × 0.86 = 6.88 oz. At the default 8% fragrance load you’d add 0.55 oz of fragrance oil, for 7.43 oz of total blend. A 10 lb bag of wax fills about 23 candles this size.

Frequently Asked Questions
How much wax do I need for an 8 oz candle?
6.88 oz of wax. An 8 oz container holds 8 oz of water by weight at the fill line, and wax weighs about 86% as much as the same volume of water, so 8 × 0.86 = 6.88 oz. At the default 8% fragrance load you’d add 0.55 oz of fragrance oil, for 7.43 oz of total blend. A 10 lb bag of wax fills about 23 candles this size.
Is fragrance load based on wax weight or total candle weight?
Wax weight. An 8% load on 6.88 oz of wax means 6.88 × 0.08 = 0.55 oz of fragrance oil — not 8% of the finished 7.43 oz blend. Calculating from total weight understates the oil, and the error compounds across a batch. Stay within your wax’s rated maximum: typically 10% for soy like GW464, up to 12% for some paraffin and coconut blends.
How many candles will 10 lb of wax make?
About 23 standard 8 oz candles. Ten pounds is 160 oz of wax, and each 8 oz container takes 6.88 oz, so 160 ÷ 6.88 ≈ 23. For 12 oz vessels (10.32 oz of wax each) the same bag yields about 15 candles, and 4 oz sample tins (3.44 oz each) stretch to roughly 46. Enter your container count in the calculator to size the batch exactly.
