Getting Started with Candle Making
Candle making is one of the most accessible crafts to start at home, and one of the few hobbies that can turn into a profitable small business. Whether you are making candles for gifts, home decor, or to sell on Etsy, understanding the math behind your materials saves money and produces better results.
The three core calculations every candle maker needs are: how much wax fills your container, how much fragrance oil gives optimal scent throw without safety issues, and what price covers your costs while leaving room for profit. Our calculators handle all three.
Choosing the Right Wax
Soy Wax (464/444)
The most popular choice for container candles. Soy wax is natural, renewable, burns cleanly, and has a density of 0.86 oz/fl oz. It has a lower melting point (120-180°F) making it beginner-friendly. Golden Brands 464 is the industry standard for single-pour containers.
Coconut Wax
Premium option with excellent scent throw and a creamy appearance. Density of 0.90 oz/fl oz. More expensive than soy but produces a luxury product. Often blended with other waxes for improved performance and cost management.
Paraffin
The traditional candle wax with the strongest scent throw and best glass adhesion. Density of 0.90 oz/fl oz. Easier to achieve smooth tops and vibrant colors. Petroleum-based, which some customers prefer to avoid.
Beeswax
Natural wax with a subtle honey scent and the highest density at 0.96 oz/fl oz. Burns longest of any wax type. Best for pillar candles and natural products. Limited fragrance capacity compared to other waxes.
How These Calculators Work Together
Start with the Candle Wax Calculator to determine how much wax your containers need. Enter your container dimensions or volume, select your wax type, and get the exact weight including a 10-15% overage for pour pot residue and second pours.
Next, use the Fragrance Calculator to find the right amount of fragrance oil. Input your total wax weight and target fragrance load percentage (6-10% for most waxes). The calculator shows both the fragrance weight and the adjusted wax weight after adding fragrance.
Finally, plug your material costs into the Batch Cost Calculator to set profitable retail prices. Include wax, fragrance, wicks, containers, labels, packaging, your labor time, and overhead. The calculator suggests retail and wholesale prices at your target margin.
Pricing Candles for Profit
A common mistake new candle makers make is pricing too low. An 8oz soy candle typically costs $3-5 in materials (wax, fragrance, wick, container, label). Add labor, packaging, platform fees (Etsy takes roughly 12%), and shipping supplies, and your true cost per candle is often $8-12.
Apply a 2x-2.5x markup on total costs for retail pricing. This means an 8oz candle should retail for $18-28, which aligns with market expectations for handmade candles. If you plan to sell wholesale to shops, price retail at 2.5x so your 50% wholesale discount still covers costs.
Track your actual costs for at least 5 batches before finalizing prices. Real-world material usage, cure time, failed pours, and shipping damage all affect your true cost per unit.
Frequently Asked Questions
How much wax do I need to make a candle?
The amount of wax depends on your container size and wax type. Multiply the container volume (in fluid ounces) by the wax density (0.86 for soy, 0.90 for paraffin or coconut, 0.96 for beeswax) and fill percentage (typically 85%). For example, a 9oz jar needs about 7oz of soy wax. Use our Candle Wax Calculator for exact amounts.
What percentage of fragrance oil should I use?
Fragrance load depends on your wax type. Soy wax typically holds 6-10% fragrance oil, paraffin 6-12%, and coconut wax 6-10%. Start at the lower end and test burn before increasing. Too much fragrance can cause sweating, poor burn, or safety issues. Our Fragrance Calculator provides exact amounts by wax type.
Which wax is best for beginners?
Soy wax (like Golden Brands 464) is the most beginner-friendly option. It has good scent throw, easy cleanup with soap and water, a forgiving melt point, and produces clean-burning candles. Paraffin is easier to work with for smooth tops but is petroleum-based. Coconut wax blends offer excellent scent throw but cost more.
How do I price my candles for profit?
Use the formula: (Materials + Labor + Overhead) x Markup = Retail Price. For an 8oz soy candle, typical material costs are $3-5. Add your labor time, packaging, and overhead, then apply a 2-2.5x markup for retail or 1.5x for wholesale. An 8oz candle typically retails for $18-28 depending on branding and market. Use our Batch Cost Calculator for precise pricing.
What wick size should I use for my candle?
Wick size depends on container diameter: 2-inch containers need a small wick (CD 6-8), 3-inch containers need medium (CD 10-14), and 4-inch or larger containers often need multiple wicks. Always test burn your candles — the right wick creates a full melt pool within 1-2 hours without tunneling or excessive soot.
How do I avoid sinkholes and wet spots in candles?
Sinkholes form when wax contracts as it cools. Pour at a lower temperature (120-135°F for soy), use a heat gun to smooth the top after cooling, or plan for a second pour. Wet spots (adhesion loss on glass) are mostly cosmetic — pouring at a lower temperature and preheating jars to 100°F can reduce them. Some wet spots are unavoidable with natural waxes.
