Candle Wax Calculator
Estimate wax and fragrance oil by jar volume or by weighing the jar.
Fill jar with water to the pour line and weigh. Water weight = filled – empty.
Typical soy/paraffin: 0.85-0.95
Calculation Method
Total candle mass = volume x density. Fragrance % = percent of total mass.
Quick Formulas
- Total mass = volume x density
- Fragrance = total x (pct / 100)
- Wax = total – fragrance
Tip
Use density = 0.9 g/ml for soy. For more accuracy measure one full jar of wax and weigh it.
Details & Notes
Fragrance percentage is treated as percent of final candle weight. For accuracy, use measured values as densities vary between wax types and brands.
Example
Jar 400 ml, density 0.9 g/ml → total ≈ 360 g. At 8% fragrance: fragrance ≈ 28.8 g; wax ≈ 331.2 g.
Quick checklist
- Decide pour level before measuring volume or water weight.
- Measure water weight with a digital scale for best results.
- Adjust fragrance load to your tested throw and wax type.
Candle Wax Calculator: Measure Wax and Fragrance with Ease
Making candles needs precise measurements. The right wax and fragrance ratio keeps candles burning evenly and smelling strong. Use our free Candle Wax Calculator to find exact amounts in seconds.
Why Use a Candle Wax Calculator
Accurate ratios prevent weak scent throw and uneven burning. Instead of guessing, enter jar volume or water weight and see exact wax and fragrance weights. This cuts material waste and lowers production costs, and it gives consistent candle quality. Placing keywords like “candle making calculator” helps users find this tool.
Key Features
- Two input options: Enter jar volume in milliliters or weigh the jar with water if you do not know the volume.
- Custom fragrance load: Adjust the percentage to match soy, paraffin, beeswax, or blended wax.
- Batch calculation: Get totals for one candle or a whole batch in one click.
- Wax density setting: Set density for different wax types to get an accurate weight estimate.
- Quick copy: Copy per-candle or batch totals for shopping lists or production sheets.
How It Works
- Choose your method, volume or water weight.
- Enter jar details, wax density, and fragrance percentage.
- Add the number of candles to scale the batch.
- Click Calculate to see wax and fragrance oil weights per candle and for the full batch.
Best Practices for Accurate Results
Use a digital scale for all measurements. Test a small sample before large runs to confirm scent throw. Keep fragrance oil within 6–10 percent for most wax types. Adjust wick size after a test burn to get an even melt pool.
FAQs
How do I find jar volume if I do not know it?
Fill the jar with water to your desired pour level, weigh it, and subtract the empty jar weight. Water weight in grams equals volume in milliliters.
What fragrance percentage is best?
Most soy and paraffin candles use 6–10 percent fragrance. Start at 8 percent and test for scent throw.
Does wax type change the formula?
Yes. Soy, beeswax, and paraffin have slightly different densities. For example, soy is about 0.9 g/ml, and beeswax about 0.96 g/ml.
Can I scale for large batches?
Yes. Enter the number of candles to see the total wax and fragrance oil needed for a full batch. This works well for small business production.
Is the calculator free to use?
Yes. You can use it online as often as you like without signing up or paying hidden fees.
Can I use essential oils instead of fragrance oils?
Yes. Keep the load lower, around 3–6 percent. Essential oils have different flash points and can change burning performance.
