Candle Wax Calculator
Calculate the perfect wax amount for your candles with our Candle Wax Calculator, an essential tool for DIY candle makers.
Wax Details
How to Use This Calculator
Enter the weight of wax you plan to use and the desired fragrance load percentage. Click "Calculate" or let the inputs auto-update after editing a field to see how much fragrance oil to add for a balanced candle blend.
We round every output to two decimal places to keep the batch total and fragrance volume easy to measure on a scale. Results update immediately after you change any input, and you can always tap Reset to restore the suggested starting values.
Methodology
This calculator simply adds the fragrance oil volume to the base wax weight. It trusts the fragrance load value you provide and converts it into grams by applying the percentage to the wax amount.
Use the calculator as a starting point for testing fragrance strength with your wax and wick combination, then adjust fragrance loads within the 6–12% range that works best for your blend.
Data Source and Guidance
All calculations follow standard candle making guidelines. For more detailed fragrance ratio recommendations, see our resources.
The Formula Explained
Total Wax = Wax Weight + (Fragrance Load / 100 × Wax Weight)
Glossary
- Wax Weight: The starting amount of wax you plan to melt.
- Fragrance Load: The percentage of fragrance oil relative to wax weight.
Worked Example
If you melt 500 grams of wax and aim for a 10% fragrance load, you multiply 500 by 0.10 to get 50 grams of fragrance oil, for a total of 550 grams of combined ingredients.
Frequently Asked Questions
What is the ideal fragrance load for candles?
The ideal fragrance load typically ranges from 6% to 10% depending on the wax type and personal preference.
Can I use any type of wax with this calculator?
This calculator works with most commonly available waxes, including soy, paraffin, and beeswax.
How accurate are the results?
Results are estimates based on standard candle making practices. Always make a small test batch to verify the fragrance strength in your formula.
Why is my candle sweating?
"Sweating" can happen if you add too much fragrance. Keep fragrance loads within supplier recommendations to avoid excess oil leaching.
How do I store my candles?
Store candles in a cool, dry place away from direct sunlight to maintain scent integrity and color.
