Many of you are given a formula based on percentages.
Dealing with percentages, pounds, grams, can be daunting, even for experienced crafters. Simply put, these formulas can be difficult to modify when trying to produce products to a specific batch size. This calculator is programmed to convert ingredient percentages to ingredient weights so you can easily figure out how much additive, fragrance, or other ingredient to add to your personal care products.

How Do You Get Ingredient Percentages from Weights?
By Hand: Weigh and note each ingredient you’d like to find the percentage of. Next, execute your recipe and get a recipe total weight. With that, you are able to divide the ingredient weight by the total weight and multiply by 100 to find your ingredient’s percentage.
Example: A 15lb batch of scrub calls for 3.3lbs of sugar
3.3 ÷ 15 = 0.22 → 0.22 × 100 = 22 → Answer is 22%
How Do You Convert Percentages into Weight Amounts?
By Hand: Take an ingredient from the recipe and have its percentage divided by 100. Next, multiply the result by your recipes total weight to get your answer.
Example: A 15lb batch of scrub calls for 22% sugar
22 ÷ 100 = 0.22 → 0.22 × 15 = 3.3 → Answer is 3.3lbs
How Do I Fix Formula Percentages over 100%?
By Hand: Find a total percentage. Then divide each ingredients’ percentage by the total percentage and multiply by 100 to find its new percentage. After doing this for each ingredient you will find that your formula percentages add up to 100.
