Plan a pour in seconds. Enter your vessel capacity, batch quantity, fragrance percentage, and wax density to get the weights you need before you start melting.
Save a candle once, then load it whenever you pour again. When a candle is loaded, the batch quantity starts at 1 so you can enter exactly how many candles you want to make.
The wax amount, fragrance amount, and combined finished weight for the entire production run.
For example, a 10% fragrance percentage uses 10 units of fragrance oil for every 100 units of wax by weight.
Treat the calculator as a batching aid. Your wax maker's limits and a complete burn test should determine whether a formula is ready for production.
Wax formulas differ in how much fragrance they can accept and how much they weigh for a given volume. These figures are useful planning ranges, not a substitute for the technical sheet for your exact wax.
| Wax | Common Upper Range |
Approx. Specific Gravity |
Maker Notes |
|---|---|---|---|
| Soy Wax (464) | 10–12% | 0.90 | Widely used for container candles; 10% is a common fragrance level to evaluate during testing. |
| Paraffin | 6–10% |
0.86–0.90
|
Often chosen for a pronounced hot throw. Density can shift with the paraffin formulation and melt point. |
| Coconut Wax | 10–12% | 0.90 | Popular for its smooth burn characteristics and strong fragrance performance in properly tested formulas. |
| Beeswax | 3–6% | 0.95 | Usually accepts less added fragrance and naturally contributes a mild honey-like aroma of its own. |
| Soy-Coconut Blend | 10–12% | 0.90 | A frequently used blend when makers want to balance scent performance with clean-burning characteristics. |
| Palm Wax | 6–8% | 0.88 | Known for decorative crystal or feather-like finishes, depending on the particular palm-wax formulation. |
| Gel Wax | 5–6% | 0.97 | Used for transparent candles. Only use fragrance approved for gel applications and verify a flash point above 170°F with the supplier. |
Reference ranges can differ from one supplier or formulation to another. Confirm the fragrance limit, density, and handling instructions on the documentation for the exact wax you are using.
A small measuring or formula error can change an entire pour. Keeping your recipe weight-based and within the limits of your materials makes batches easier to repeat and troubleshoot.
Equal volumes of wax and fragrance oil do not necessarily weigh the same. For repeatable formulas, weigh fragrance on a digital scale rather than measuring it with tablespoons, cups, or other volume-based tools.
Adding extra oil is not a guaranteed way to create a stronger candle. Once the wax is overloaded, oil may migrate to the surface, seep from the candle, or interfere with burning. Use the manufacturer's stated limit as your ceiling and confirm performance with testing.
A vessel marked by fluid volume does not take the same number of ounces of wax by weight. With a specific gravity of 0.86, an 8 fl oz water capacity corresponds to roughly 6.88 oz of candle material by weight. This tool performs that conversion automatically.
The temperature at which fragrance is mixed into wax can affect incorporation and finished performance. Some wax systems call for fragrance to be added around 180–185°F (82–85°C), while others use a different window. Follow the instructions for your actual wax and oil rather than treating one temperature as universal.
Remember: The fragrance percentage is only one variable. Wax formulation, oil compatibility, wick choice, vessel diameter, cure time, and the way the candle is burned all contribute to the final result.
If a finished candle smells lighter than expected, do not assume the fix is simply more fragrance oil. Evaluate the rest of the candle system before changing the percentage.
