If you run a candle brand, you know that candle fragrance oil is one of your biggest variable costs. It typically accounts for 5-15% of your total candle cost – but it determines 80% of your customer satisfaction.

Here’s the problem: many candle makers don’t know how to calculate their true fragrance oil cost per unit. They compare supplier prices per kilogram, but ignore load percentages, waste, and shipping. The result? They leave money on the table.
This guide walks you through:
- The simple formula to calculate fragrance oil cost per candle
- How to compare candle fragrance oil supplier quotes accurately
- Strategies to lower your cost without sacrificing quality
- How to price your candles for healthy margins
Let’s dive in.
Step 1: Understand What Goes Into Fragrance Oil Cost
Before you calculate, you need to know the variables that affect your true cost.
| Variable | Why It Matters |
|---|---|
| Price per kg | The base price from your supplier |
| Fragrance load % | How much oil you add to each candle (6-10% typical) |
| Wax weight per candle | More wax = more oil needed |
| Waste factor | Oil left in containers, spillage, testing |
| Shipping cost | Freight, duties, insurance |
| Currency exchange | If buying internationally |
Most candle makers only look at “price per kg”. That’s a mistake.
Step 2: The Simple Formula
Here’s the formula to calculate your true fragrance oil cost per candle:
(Price per kg × Fragrance Load % × Wax Weight per Candle) + (Shipping per kg) = Fragrance Oil Cost Per Candle
Let’s break it down with an example.
Example Calculation
Assume:
- Fragrance oil price: $15/kg (wholesale)
- Fragrance load: 8% (0.08)
- Wax weight per candle: 200g (0.2 kg)
- Shipping cost: $2/kg
Step 1: Oil cost per candle
$15 × 0.08 × 0.2 = $0.24
Step 2: Shipping cost per candle
$2 × 0.08 × 0.2 = $0.032
Step 3: Total fragrance cost per candle
$0.24 + $0.032 = $0.272 per candle
So each candle costs you about $0.27 for fragrance oil.
Step 3: How to Compare Supplier Quotes Accurately
Suppliers quote differently. Some include shipping, some don’t. Some offer lower price per kg but higher MOQ. Here’s how to compare apples to apples.

The “Landed Cost Per Candle” Method
Instead of comparing price per kg, calculate the landed cost per candle for each supplier.
| Supplier | Price/kg | Shipping/kg | Load % | Cost per Candle (200g wax) |
|---|---|---|---|---|
| Supplier A | $12 | $3 | 8% | $0.24 |
| Supplier B | $14 | $1.50 | 7% | $0.217 |
| Supplier C | $10 | $5 | 9% | $0.27 |
Supplier B looks more expensive per kg, but ends up cheaper per candle because of lower shipping and lower load requirement.
Key takeaway: Always calculate landed cost per unit, not price per kg.
Step 4: How to Lower Your Fragrance Oil Cost
Here are practical ways to reduce your fragrance oil cost without compromising quality.
4.1 Optimize Your Fragrance Load
Most waxes work well between 6-10%. Test if you can use 7% instead of 10%.
| Load % | Cost per 100 candles (200g wax, $15/kg oil) | Savings |
|---|---|---|
| 10% | $30 | – |
| 8% | $24 | $6 |
| 6% | $18 | $12 |
Save 20-40% just by testing lower loads.
4.2 Buy Larger Quantities
Volume discounts are real. Here’s a typical pricing tier:
| Quantity | Price per kg | Cost per candle (8% load) |
|---|---|---|
| 1-5 kg | $18 | $0.288 |
| 6-10 kg | $15 | $0.24 |
| 11-25 kg | $13 | $0.208 |
| 25+ kg | $11 | $0.176 |
Upgrading from 5kg to 25kg saves you 39% on fragrance cost.
4.3 Choose DDP Shipping for Small Volumes
For orders under 50kg, DDP (Delivered Duty Paid) often works out cheaper than FOB.
| Shipping Method | Price/kg | Hidden Costs | Total/kg |
|---|---|---|---|
| FOB + your freight | $12 | +$4 freight + customs + tax | $18+ |
| DDP (all included) | $16 | $0 | $16 |
DDP gives you predictable cost per unit – no surprises.
4.4 Reduce Waste
Track these three waste sources:
| Waste Source | Typical % | How to Reduce |
|---|---|---|
| Residue in containers | 2-5% | Use wider-mouth containers, scrape properly |
| Spillage during mixing | 1-2% | Use pumps or spouts, train staff |
| Testing waste | Varies | Keep a testing log, reuse test candles |
Cutting waste from 7% to 3% saves you 4% on fragrance cost.
Step 5: How to Price Your Candles for Healthy Margins
Once you know your true fragrance oil cost, use this markup guide.
Standard Margin Targets for Candle Brands
| Channel | Target COGS % | Markup Multiplier |
|---|---|---|
| Direct-to-consumer (website) | 25-30% | 3.3x – 4x |
| Wholesale to retailers | 40-50% | 2x – 2.5x |
| Private label manufacturing | 50-60% | 1.7x – 2x |
Example: DTC Pricing
If your total candle COGS (wax + fragrance + wick + vessel + label) is $4.00:
- Target COGS %: 28%
- Minimum retail price: $4.00 ÷ 0.28 = $14.30
If fragrance oil is $0.27 of that $4.00, you can see how a $0.10 saving on fragrance adds $0.36 to your margin on a $14 candle.
Step 6: A Simple Tool You Can Use
Here’s a spreadsheet template you can copy:
| Item | Value | Unit |
|---|---|---|
| Fragrance oil price per kg | $___ | /kg |
| Shipping per kg | $___ | /kg |
| Fragrance load | ___% | |
| Wax weight per candle | ___g | |
| Fragrance cost per candle | $___ |
Formula:
= (Price/kg + Shipping/kg) * (Load% * Wax weight in kg)
