Candle COGS Explained: Know Your True Costs

What Is COGS?

Cost of Goods Sold (COGS) is the total cost of materials and direct labor that go into making one unit of your product. For candle makers, it's the answer to the question: "How much does it actually cost me to make this candle?"

COGS is not the same as your total business expenses. It doesn't include rent, marketing, or your Shopify subscription. It's specifically the cost of producing the product itself.

Why COGS Matters for Candle Businesses

If you don't know your COGS, you don't know your profit margin. Period.

Here's what happens when candle makers skip COGS tracking:

• Underpricing: You sell a candle for $18 thinking you make $10 profit — but your true cost is $11, so you're only making $7
• Invisible losses: A supply price goes up 15% and you don't notice for months
• Tax problems: COGS is a tax deduction — if you don't track it, you overpay the IRS
• Bad product decisions: You can't know which candles are most profitable without per-unit costs

Direct Costs: The Obvious Stuff

These are the materials that physically go into your candle. Most makers track these (at least roughly):

🕯️ Wax

Your biggest ingredient by weight. Soy wax typically runs $2–4/lb depending on supplier and quantity. For an 8oz candle, you'll use roughly 6–7oz of wax.

Cost per candle: $0.75–$1.75 depending on wax type and supplier.

🌸 Fragrance Oil

Usually the most expensive per-unit ingredient. At a typical 8–10% fragrance load, an 8oz candle uses about 0.6–0.7oz of fragrance oil. Premium fragrance oils can run $3–8/oz at small quantities.

Cost per candle: $1.00–$3.50 depending on fragrance quality and load.

🧶 Wick

Often overlooked because they're cheap individually — but they add up. Pre-tabbed wicks cost $0.10–0.30 each depending on type and quantity.

Cost per candle: $0.10–$0.30

🫙 Container

Jars, tins, or vessels. This varies wildly — from $0.50 for a basic tin to $3+ for a premium glass jar with a lid. Buying in bulk (cases of 24+) saves significantly.

Cost per candle: $0.50–$3.00+

🏷️ Labels & Packaging

Custom labels, warning stickers, boxes, tissue paper, shrink wrap. These feel small but typically add $0.30–$1.00+ per candle.

Cost per candle: $0.30–$1.00+

Hidden Costs Most Makers Forget

This is where most candle makers undercount their COGS. These costs are real and should be allocated per unit:

🎨 Dye & Additives

Candle dye, UV inhibitors, vybar — small amounts per candle but they add up across batches. Usually $0.05–$0.15 per candle.

⏱️ Labor

Your time has value. Even if you don't pay yourself yet, you should account for labor in COGS. How long does it take to make a batch of 12 candles? If it takes 2 hours and you value your time at $20/hr, that's $3.33 per candle in labor.

Most forgotten cost. If you ever want to hire help or scale, labor costs are real.

📦 Shipping Materials (for online orders)

Boxes, bubble wrap, tape, packing peanuts. If you sell online, these are part of your per-unit cost. Usually $1–3 per shipment.

🔥 Testing & Waste

Failed pours, test candles, samples you give away. A typical candle maker wastes 5–10% of materials. Factor this into your COGS by adding 5–10% to your material costs.

Real Example: 8oz Soy Candle Breakdown

Let's walk through a realistic COGS calculation for a standard 8oz soy candle:

If you sell this candle for $22, your gross profit is $13.31 (60.5% margin). That's healthy. But if you forgot labor and waste, you'd think your COGS was $4.99 and your margin was 77% — a dangerous overestimate.

The COGS Formula

Here's the formula for calculating per-unit COGS:

For your total business COGS over a period (for taxes):

This second formula is what you'll use on your tax return (Schedule C). It accounts for inventory you bought but haven't used yet.

Common COGS Mistakes

1. Forgetting Labor

"But I don't pay myself." Doesn't matter. If you want to know true profitability — or ever plan to hire — labor must be in COGS. Even $15/hr changes the math significantly.

2. Using Retail Prices for Materials

If you buy wax at retail (small quantities from Amazon), your COGS will be inflated. As you grow, buying wholesale (50lb cases) can cut material costs 20–40%.

3. Not Updating When Prices Change

Fragrance oil prices change. Shipping costs fluctuate. If you calculated COGS once in 2024 and never updated it, your numbers are wrong. Review quarterly at minimum.

4. Averaging Across Products

A 4oz tin and a 16oz three-wick have very different COGS. Calculate per-product, not as an average. Your most profitable candle might not be the one you think.

5. Ignoring Craft Fair Costs

Booth fees, table displays, gas, and time at the event are selling expenses (not COGS), but they affect your per-unit profit. If you sell 50 candles at a $150 booth, that's $3/candle in selling costs on top of COGS. Compare booth fees across events on TheCraftMap to keep these costs down.

How to Track COGS Easily

Spreadsheets work when you have 5 products. But as you grow — more fragrances, different container sizes, wax price changes — spreadsheets become a nightmare.

Here's what you need:

• Per-supply cost tracking — Know what you paid for each material
• Recipe-based COGS — Attach supplies to products with exact quantities
• Automatic recalculation — When a supply price changes, all product COGS should update
• Historical tracking — See how your costs change over time

Key Takeaways

• COGS includes all direct costs — materials, labor, packaging, and waste
• Most candle makers undercount by 30–50% because they forget labor and hidden costs
• Calculate COGS per product, not as an average
• Review and update your costs at least quarterly
• Accurate COGS = accurate pricing = actual profit

Understanding your COGS is the foundation of a profitable candle business. It's not glamorous, but it's what separates hobby makers from business owners. Start tracking today — your future self (and your accountant) will thank you.
