1Blend by percentage
Use a blend such as 70% / 30% or 60% / 30% / 10%. Your percentages must add up to 100%, and the calculator shows the exact weight of each wax.
Wax Blend Ratio Calculator
Free candle-making tool
Enter Your Wax Ratio and See Exactly What to Weigh
Enter how much wax you want to make, choose two or three waxes, then enter the blend as percentages or recipe parts. The calculator shows exactly how much of each wax to weigh, and you can switch between grams, ounces and pounds without changing your batch.
2Scale recipe parts
Already have a recipe written as 7:3 or 6:3:1? Enter those numbers as parts. The calculator keeps the same ratio and works out the exact wax weights for your batch.
The calculator tells you what to weigh; a test candle tells you how the blend performs. Different wax brands and products can behave differently even when they are both called soy, paraffin, coconut or another wax type. Follow your supplier's instructions and burn-test the finished wax, fragrance, dye and wick combination before making a large batch.

How to calculate a candle wax blend by weight
For the easiest repeatable recipe, weigh every wax in your blend. Use percentages if your recipe is written like 70% / 30%, or use recipe parts if it is written like 7:3 or 6:3:1.
Use percentages when your blend adds up to 100%
Choose this method when each wax is already written as a percentage of the whole wax batch.
For each wax, multiply the total wax batch by its percentage. The calculator does this for two or three waxes. You can also switch between grams, ounces and pounds without changing the actual batch size.
Wax A weightTotal wax batch × Wax A % ÷ 100
Wax B weightTotal wax batch × Wax B % ÷ 100
Optional Wax CTotal wax batch × Wax C % ÷ 100
Quick checkWax A % + Wax B % (+ Wax C %) = 100%
Worked example: 1,000 g at 70% / 30%
Total wax batch1,000 g
Blend ratio70% / 30%
Wax A1,000 × 0.70 = 700 g
Wax B1,000 × 0.30 = 300 g
Weigh 700 g of Wax A and 300 g of Wax B. Together, the two waxes make the full 1,000 g batch.
Use recipe parts when your blend is written as a ratio
If your recipe says 7:3 or 6:3:1, you can enter those numbers directly instead of converting them to percentages first.
Add all the parts together. Then divide each wax's parts by that total to find its share of the batch. The calculator does this automatically, so you only need to enter the ratio you already use.
Total partsWax A parts + Wax B parts (+ Wax C parts)
Each wax's shareThat wax's parts ÷ total parts
Wax weightTotal wax batch × that wax's share
Easy example6:3:1 = 60% : 30% : 10%
Worked example: 5 lb at 6 : 3 : 1
Total parts6 + 3 + 1 = 10
Wax A5 × 6/10 = 3 lb
Wax B5 × 3/10 = 1.5 lb
Wax C5 × 1/10 = 0.5 lb
Weigh 3 lb of Wax A, 1.5 lb of Wax B and 0.5 lb of Wax C. Together, they make the full 5 lb batch.
Test the blend before making a large batch
The calculator can make the ratio exact, but the finished candle still depends on the exact wax products you use.
- 1Write down the exact wax products
Two products can both be called soy, paraffin or coconut wax and still behave differently. Record the brand, supplier and product name so you can repeat a successful blend later.
- 2Make a batch your scale can measure
If one wax comes out as a tiny amount, it may be difficult to weigh accurately. The calculator warns you when a more precise scale or a larger test batch would be better.
- 3Follow the instructions for each wax
Melting, mixing, fragrance, pouring and cooling guidance can vary by product. Use the instructions from your wax supplier instead of one temperature or cure rule for every blend.
- 4Burn-test again after changing the blend
A different wax blend can change the melt pool, wick performance, appearance, scent throw and cooling. Change one thing at a time and keep notes on every test.
Why this calculator does not guess density or a maximum fragrance load: those values depend on the exact wax products you are using. Generic values for “soy,” “paraffin” or “coconut” can be misleading. Check your wax supplier's limits, then use the Candle Fragrance Load Calculator to work out your fragrance amount.
Next step: once your wax and fragrance recipe is set, use the Candle Wick Size Estimator for a starting wick size and the Candle Burn Time Calculator when you have real burn-test measurements.
Helpful answers
Wax blend ratio calculator FAQs
Simple answers about percentages, recipe parts, units, two- and three-wax blends, small measurements and testing.
How do I calculate a wax blend percentage?
Multiply your total wax batch by each wax percentage. For a 1,000 g batch at 70% / 30%, Wax A is 700 g and Wax B is 300 g. All the wax percentages must add up to 100%.
What is the difference between percentages and recipe parts?
Percentages show how much of the whole batch each wax uses. Recipe parts show the same mix as a simple ratio. For example, 7:3 is the same blend as 70% / 30%, and 6:3:1 is the same as 60% / 30% / 10%. Use the format your recipe already uses.
Can I blend three candle waxes?
Yes. Select “Add third wax,” then enter the percentages or recipe parts for all three waxes. Wax A, Wax B and Wax C each get their own colour-coded result box so they are easy to tell apart when you weigh them.
Why must percentages add up to 100%?
The percentages describe the whole wax batch. If they add up to less or more than 100%, the wax weights will not match the batch size you entered. “Balance last wax” can fill in the percentage that is left.
Can I select the same wax twice?
The calculator blocks accidental duplicates so the same ingredient is not counted twice. If you really are using two different products of the same wax type, choose “Other / Custom” and give each product a different name.
Can I switch between grams, ounces and pounds?
Yes. You can change units at any time. The calculator remembers the actual wax amount, so switching between grams, ounces and pounds does not change your batch or your blend ratio.
Does total batch weight include fragrance oil or dye?
No. Enter the weight of the wax only. After your wax blend is set, use the Candle Fragrance Load Calculator to work out the fragrance oil for that wax amount.
Are the quick-start buttons recommended wax recipes?
No. They are math examples that show how the calculator works. Different wax brands and products can behave differently, so use your wax supplier's instructions and your own test results to choose the blend you actually make.
What if one wax amount is too small for my scale?
The calculator keeps the correct small amount instead of rounding it to zero. If the amount may be too small for a common candle scale, you will see a warning. Make a larger test batch or use a more precise scale so you can weigh that wax reliably.
What is the best soy, paraffin, coconut or beeswax blend ratio?
There is no single best ratio for every candle. Two wax products with the same general name can still behave differently, and fragrance, dye, wick, candle shape and your making process can also change the result. Start with guidance for your exact wax products, then make small test batches.
Why does the calculator not estimate blended density or maximum fragrance load?
Those numbers depend on the exact wax products you use. A generic value for “soy,” “paraffin” or “coconut” may not match your wax and could give you a misleading answer. Check the limits from your wax supplier, then calculate fragrance from the wax amount in your tested blend.
Do I need to wick-test again after changing my wax blend?
Yes. Changing the wax blend can change how wax feeds the wick, the melt pool and the candle temperature. Test the complete candle again with its wax, fragrance, dye, container or mold and wick. Use the Candle Wick Size Estimator for a starting wick size, then confirm it with a full burn test.
From wax ratio to a complete, tested candle formula
Once the wax blend is weighed, calculate fragrance from the correct wax basis, choose a wick starting point and use measured testing before the formula is scaled.
