Fragrance Calculator

Many fragrances, essential oils, preservatives, and active ingredients have maximum usage rates expressed as percentages. This tool helps you calculate exactly how much you can safely add based on your total batch weight.

How to calculate the percentage of a recipe?
Divide the weight of the ingredient by the total recipe weight, then multiply by 100. The calculator does this for you instantly.
How to calculate the yield percentage in a recipe?
Yield percentage is the weight of your final product divided by the weight of all raw ingredients, multiplied by 100. This helps you track efficiency and product loss during production.

Make, Scale, Repeat with Confidence
The Percentage Calculator is a must-have tool for makers who want consistent results and professional-quality recipes. From soaps to lotions to candles, it’s your shortcut to accuracy and efficiency. Formulate your recipes with precision using our Percentage Calculator. Whether you’re scaling up a lotion batch, adjusting a soap formula, or balancing a candle recipe, this tool helps you convert ingredient weights into accurate percentages — ensuring consistent results every time.


Enter your ingredient weights, and the calculator instantly converts them to percentages. Perfect for adjusting batch sizes, scaling recipes, and making sure you meet fragrance, preservative, and additive guidelines.

  • Consistency in every batch – Scale recipes up or down without throwing off proportions.
  • Safety compliance – Stay within recommended usage rates for fragrances, preservatives, and other additives.
  • Professional formulation – Standardize your recipes for repeatability and production efficiency.

If you’ve been creating products by volume (cups, teaspoons, scoops), you may find it tricky to scale your recipe or share it with others. Our calculator makes it simple:

  1. Weigh each ingredient in ounces, pounds, or grams.
  2. Enter the weights into the calculator.
  3. See the percentages calculated instantly, based on the total weight of the batch.

Tip: Use the calculator before adding fragrance or preservatives to determine the correct percentage for those ingredients. Let’s say you made a lotion with:

  • 16 oz. distilled water
  • 8 oz. oil blend
  • 4 oz. emulsifying wax

The total batch weight is 28 oz.

  • Water: (16 ÷ 28) × 100 = 57.14%
  • Oil blend: (8 ÷ 28) × 100 = 28.57%
  • Emulsifying wax: (4 ÷ 28) × 100 = 14.29%

Our calculator does this instantly — no math required. Need to turn a small test batch into a full production run? The percentage calculator lets you scale ingredient amounts proportionally, so your formula stays balanced and performs as expected.
