Knowing exactly how much wax you need is essential for successful candle making. Using too little leaves the container under-filled, while using too much causes overflow and waste. This free Candle Wax Calculator helps you quickly calculate the right amount of wax and fragrance oil based on your container size and wax type.
Candle Wax Calculator
Calculate exactly how much wax and fragrance oil you need.
Calculation includes a small buffer for wick displacement. Results are approximate and may vary slightly by wax brand.
Frequently Asked Questions
How does the candle wax calculator work?
+
It multiplies your container volume by the density of the selected wax type and adjusts for fragrance load. A small buffer is included to account for the wick and safe fill level.
What fragrance load should I use?
+
Most candle makers use 6% to 10%. 8% is a safe and popular starting point for soy wax. Always check the maximum recommended load for your specific wax and fragrance oil.
Why do different waxes need different amounts?
+
Waxes have different densities. Beeswax is heavier than soy wax, so you need more weight of beeswax to fill the same container volume.
Should I fill the container completely?
+
No. Leave a small gap at the top (usually ½ inch) for a clean look and to prevent overflow when the wax melts.
Can I use this for pillar candles?
+
This calculator is designed mainly for container candles. Pillar candles require different calculations because they are not poured into a container.
