Important · Read Before Calculating
Fragrance percentage is by weight of wax, not total candle
The candle making industry standard is to calculate fragrance load as a percentage of wax weight, not total candle weight. This distinction matters because it affects how much fragrance you actually add. A "100g candle with 8% fragrance load" means 100g of wax plus 8g of fragrance oil, for a total candle weight of 108g.
For a 100g candle at 8% load: 100g wax + 8g fragrance = 108g total candle weight. Not 92g wax + 8g fragrance = 100g total. Always calculate fragrance as a percentage of wax weight, then add the fragrance to that wax quantity.
Fragrance load is the single most impactful decision in candle making. Too little fragrance produces beautiful candles that smell weak when burning. Too much fragrance produces sweating, sinkholes, and combustion problems. The 6-10% range exists because it is the trial-sorted working zone where fragrance throws strongly without breaking the candle. Every percentage point inside this range affects throw, every percentage point outside it affects candle quality.
"6% is the minimum for noticeable throw. 8% is the safe recommendation. 10% is the maximum that works with Vybar. Outside this range, problems develop faster than benefits."
The fragrance load percentage controls how much aroma molecule density is suspended in the wax structure. Below 6%, the molecule density is too sparse for the burning candle to release sufficient aroma into the room. Above 10%, the molecule density exceeds what most candle waxes can structurally retain, causing the excess fragrance to separate during cure or burn incompletely during use. The 6-10% range is not a marketing recommendation, it is the chemistry constraint of how candle waxes interact with fragrance oils. This guide explains where in that range your specific candle should be, with calculations and reasoning.
The CSI 6-10% range: when to use each load
The three load levels in the CSI standard serve different candles for different purposes. Choosing the right level depends on your candle size, fragrance type, target user, and whether you use Vybar additive. Below is the detailed framework for choosing your load.

For Sensitive Spaces
For a 100g candle, 6g of fragrance oil produces subtle throw suitable for bedrooms, small offices, sensitive users, and spaces under 12 square meters. The fragrance is noticeable when burning but does not dominate the space. This is the safe choice for fragrance-sensitive customers or rooms where heavy scent would be overwhelming.

Requires Vybar
For a 100g candle, 10g of fragrance oil is the maximum practical load. This level requires Vybar additive at 1% to prevent sweating, sinkholes, and combustion issues. Without Vybar, the wax cannot retain this much fragrance properly. Use for large rooms above 20 square meters, premium candles where maximum throw is the priority, and light fragrances (citrus, fresh) that benefit from higher loads.

8g
of fragrance oil for your candle, at 8% load
The calculator uses simple multiplication: wax weight x load percentage = fragrance weight. For example, 100g wax x 0.08 = 8g fragrance. Add this fragrance to your melted wax at 80C, stir for 60 seconds, then pour.
If calculator does not load Use this simple formula: fragrance grams = wax grams x percentage / 100. For example: 100g wax at 8% = 100 x 8 / 100 = 8g fragrance. For 500g wax at 8% = 500 x 8 / 100 = 40g fragrance. Always weigh fragrance oil precisely using a digital scale.

The fragrance calculation explained
Understanding the calculation lets you calculate fragrance for any custom candle size not listed in the tables above. The math is simpler than wax calculations because fragrance is straightforward percentage of wax weight.
The Fragrance Load Formula · Step by Step
Step 1: Determine your wax weight
Weigh your wax precisely using a digital scale. For a 100g candle, this is 100g of wax (not 100g total candle).
Step 2: Choose your load percentage
Pick from the CSI range:
Step 3: Calculate fragrance grams
For 100g wax at 8%:
Step 4: Weigh fragrance precisely
Use a digital scale to weigh fragrance oil to the nearest 0.1g. Precision matters more for small candles (50g) than large batches (1000g+).
For any custom size, the formula stays the same. 250g wax at 8% = 250 x 0.08 = 20g fragrance. 750g wax at 9% = 750 x 0.09 = 67.5g fragrance.

Fragrance cost per candle
For makers planning commercial production, understanding fragrance cost per candle helps with pricing decisions. Below is the cost breakdown across common candle sizes at the recommended 8% load.
Fragrance Cost · 8% Load · Rs Per Candle
Per-candle fragrance economics
| Candle Size | Fragrance Needed | Fragrance Cost | Cost Range |
|---|---|---|---|
| 50g tealight | 4g | Rs 7-12 | Rs 7-12 per candle |
| 100g small candle | 8g | Rs 14-24 | Rs 14-24 per candle |
| 175g standard 200ml | 14g | Rs 25-42 | Rs 25-42 per candle |
| 250g pillar | 20g | Rs 35-60 | Rs 35-60 per candle |
| 300g large candle | 24g | Rs 42-72 | Rs 42-72 per candle |
| 500g luxury candle | 40g | Rs 70-120 | Rs 70-120 per candle |
Cost ranges reflect Indian market pricing for IFRA-compliant fragrance oils (Rs 1.75-3 per gram depending on type and quantity). Premium fragrances cost more, basic fragrances cost less. Bulk purchases of 250g+ reduce per-gram cost by 20-30%.
Common fragrance load mistakes
Several mistakes commonly trip up makers when calculating and adding fragrance. Recognising these helps you avoid throw problems and candle quality issues.
Failure Modes · Common Fragrance Mistakes
Six fragrance load mistakes to avoid
- Calculating percentage from total candle weight instead of wax weightThe industry standard is percentage of wax weight, not total weight. A maker who calculates 8% of 100g total (8g fragrance + 92g wax) ends up with significantly less fragrance than 8% of 100g wax (8g fragrance + 100g wax). Both candles have the same "8% label" but different actual fragrance density.The fix: Always weigh wax first, then calculate fragrance as a percentage of wax weight. Add the fragrance on top of the wax weight, not within it.
- Adding more than 10% hoping for stronger throwAbove 10%, candle waxes cannot structurally retain the additional fragrance. The excess separates during cure (sweating) or burns incompletely (smoking). 12% load produces less effective throw than 10% load because most of the extra fragrance is wasted.The fix: Stay within 6-10% range. If you need stronger throw, use Vybar at 1% at the 10% level rather than increasing fragrance further. Vybar improves throw without breaking the wax structure.
- Adding fragrance at wrong temperatureFragrance added above 90C wax temperature damages the fragrance compounds, reducing throw and shortening shelf life. Fragrance added below 75C doesn't integrate properly with the wax structure. The 80-85C window matters significantly.The fix: Always add fragrance at 80-85C. Verify with a thermometer, not the melter dial. Stir for 60 seconds after adding to ensure full integration.
- Not weighing fragrance oil preciselyVolume measurements (drops, dashes, "a teaspoon") are not accurate enough. 8g of fragrance is approximately 8ml but varies by fragrance density. Weighing produces consistent results, volume estimation produces inconsistent candles.The fix: Use a digital scale to weigh fragrance to the nearest 0.1g. The Rs 500-800 scale investment is essential for consistent fragrance loads across batches.
- Choosing 6% load and complaining about weak throw6% load is intentionally subtle. If you want strong throw, use 8% or 10%. The maker who chooses 6% for "safety" then complains about weak throw chose the wrong load for their goal, not made a poor candle.The fix: Match your load to your goal. Strong throw needs 8-10%. Subtle throw needs 6%. Choose intentionally rather than picking the lowest "safe" value and being disappointed.
- Using essential oils at the same percentages as fragrance oilsEssential oils are not interchangeable with fragrance oils. Most essential oils flashpoint below 80C, meaning they evaporate too quickly during melting. Most also have much lower concentration loads (3-5% maximum). Following 8% rules with essential oils produces poor throw and potential safety issues.The fix: The 6-10% range applies to fragrance oils, not essential oils. For essential oils, use 3-5% maximum and add at lower wax temperature (65-70C). This is a different category of ingredient with different rules.
Working tip: the test batch protocol for new fragrances
When trying a new fragrance for the first time, make three small candles at 6%, 8%, and 10% load before committing to a production batch. Burn each candle for 2 hours in your target room size. The 6% version tells you the minimum noticeable throw. The 8% version tells you the standard production result. The 10% version (with Vybar) tells you the maximum potential. This three-candle test reveals which load suits the specific fragrance, your space, and your target customer. Some fragrances throw beautifully at 6%, others need 10% to be noticeable. Generic recommendations cannot predict this, only the test batch can.Used by 500+ small candle brands across India

Grounding · Fragrance Load Chemistry
Fragrance load percentages are calibrated against wax retention capacity, which is determined by the molecular structure of specific waxes. Paraffin can structurally retain 8-10% fragrance, soy approximately 6-10%, and beeswax 4-6%. Above these capacities, fragrance molecules cannot bond with the wax matrix and either evaporate during cure or separate during cool. The 6-10% range used by CSI is the working zone for paraffin and standard soy waxes commonly used in Indian candle production. The IFRA (International Fragrance Association) provides safety guidelines for specific fragrance compounds at various concentrations, which underlies the 10% practical maximum across most candle applications.

Frequently asked questions
How much fragrance oil for 100g candle?
For a 100g candle (measured by wax weight), use 6 to 10 grams of fragrance oil depending on desired throw strength. The CSI standard range is 6% (6g, light throw for sensitive users), 8% (8g, balanced throw recommended for most candles), or 10% (10g, maximum throw requiring Vybar additive). 8g is the safe starting point for first-time makers.
What percentage of fragrance oil should I add to candles?
The CSI recommended fragrance load is 6-10% by weight of wax. 6% produces subtle throw suitable for sensitive users and small spaces. 8% is the balanced sweet spot that works for most fragrances and candle sizes. 10% produces maximum throw but typically requires Vybar additive at 1% to prevent sweating or sinkholes. Above 10% produces diminishing returns and increased problems.
Is fragrance percentage by weight of wax or total candle?
Fragrance percentage is calculated by weight of wax, not total candle weight. This is the industry standard. So a 100g candle with 8% fragrance load means 100g wax plus 8g fragrance oil, for a total candle weight of 108g. Always calculate from wax weight, not from desired total candle weight.
Can I add more than 10% fragrance oil?
Above 10% fragrance load produces diminishing returns and increases problems including sweating, sinkholes, and combustion issues that can cause smoking. Most candle waxes cannot retain more than 10-12% fragrance even with Vybar additive. The maximum practical load is 10% with Vybar at 1%. Beyond this, the additional fragrance separates from the wax during cure rather than improving throw.
How much fragrance for a 200g candle?
For a 200g candle at CSI's recommended 8% load, use 16g of fragrance oil. For lighter throw (6%), use 12g. For maximum throw (10% with Vybar), use 20g. The math is simple: multiply wax weight by the percentage. 200g wax x 0.08 = 16g fragrance oil.
How much fragrance for 500g of wax?
For 500g of wax at CSI's recommended 8% load, use 40g of fragrance oil. For lighter throw (6%), use 30g. For maximum throw (10% with Vybar), use 50g. The 500g batch is the most common starter batch size in Indian candle production.
Can I use essential oils at the same percentage as fragrance oils?
No, essential oils follow different rules. Most essential oils have lower flashpoints (evaporate during melting), lower concentration tolerances (3-5% maximum vs 6-10% for fragrance oils), and need to be added at lower wax temperatures (65-70C). The CSI 6-10% range applies specifically to wax-engineered fragrance oils, not essential oils.
