Fragrance and Blending Calculator Get precise fragrance calculations for any project
Formulating unique fragrances for your products just got easier!
The Fragrance and Blending Calculator makes it simple to create signature scents quickly and accurately:
- Pick up to 4 fragrances to build your blend.
- Set the blend ratios.
- Select the product type for the blend.
- Choose the desired fragrance load from the slider options.
This calculator also helps you determine the amount of fragrance for single-scent products. Just select one fragrance in that case!
Our goal is to make calculating fragrance amounts as simple as possible, so that creating your products and blending is easy for everyone.
If you have any feedback or suggestions about the calculator, we’d love to hear from you—please share your thoughts using this feedback form. Thank you for helping us improve this tool!
Frequently Asked Questions
The fragrance wheel is a handy guide that helps you see how different scent families relate to each other—think of it like the color wheel you may have used in art class! It’s a great way to find complementary or kindred fragrance notes when creating your own blends for candles, soaps, room sprays, and more. If you’d like to learn more about blending, check out The Fragrance Wheel: Notes, Families, and How to Use It.
The wheel beside each fragrance shows you the dominant fragrance notes in that scent to help you decide what fragrance may blend well together. Learn more at The Fragrance Wheel: Notes, Families, and How to Use It.
Determine what notes you’d like to be dominant. Use a higher percentage of those fragrances than others. The percentages that you use are subjective. We recommend testing your fragrance blend with blotter strips to prevent waste. Learn how to use blotter strips in this tutorial.
Your total blended fragrance will always add up to 100%. Every time you add or remove a fragrance your blend will shift to include or exclude that fragrance.
Not at this time, but we’re working on it! For the moment, we suggest copying the URL and saving it in a text document. That URL will bring you right back to your recipe.
We do not recommend going higher than the percentages above. These are guidelines based on our own recommendations and the IFRA certificate for each fragrances. Exceeding these recommendations can be hazardous.
The best way to know if your fragrance blend will work is to test it in your specific project—whether that’s candles, soap, room sprays, or something else! While tools like the fragrance wheel can help guide your choices and inspire creative combinations, they can’t guarantee how your blend will smell or perform in your chosen base. Every base can affect the scent differently, so don’t be afraid to experiment and make small test batches. Enjoy the process and have fun discovering your signature scent!
Great question! Whether your custom blend can be labeled as a CleanScent depends on the fragrances you use:
- CleanScents+ blended with CleanScents+ = CleanScents+
- CleanScents+ blended with CleanScents = CleanScents
- CleanScents+ or CleanScents blended with a fragrance that is not a CleanScent = Not a CleanScent
If you’re using CandleScience fragrances, even blends that aren’t considered CleanScents will still be formulated without phthalates, are California Prop 65 compliant, vegan, and cruelty free. So, you can always feel good about the quality and safety of your creations!
