About this app

I got tired of soap calculators that made simple things feel complicated — and of losing recipes I discovered in books, online, and while watching other soapmakers, because getting them into a calculator was such a hassle. I wanted a fast, reliable way to get safe lye amounts and bring those recipes home without friction. So I built Simple SoapCalc.

Simple SoapCalc is a modern soap calculator designed to make lye calculations feel clear, calm, and reliable.

Whether you're creating your first recipe or refining a favorite formula, Simple SoapCalc helps you calculate safe lye and water amounts without spreadsheets, clutter, or guesswork.

What you can do:

• Calculate accurate lye and water amounts for bar, liquid, and cream soap
• Build recipes by weight or percentage
• Import recipes from photos, screenshots, or text you find elsewhere
• Adjust superfat and water-to-lye ratio with confidence
• Save and organize your recipes for later use

Optional insights for deeper understanding:

• View estimated soap qualities like hardness, cleansing, and conditioning
• Explore fatty acid breakdowns
• All insights are informational—never pass/fail scores

A calmer approach:

Soapmaking involves chemistry and safety. Simple SoapCalc is intentionally designed to feel calm and supportive, helping you focus on making soap—not second-guessing numbers.

Always follow proper soapmaking safety practices when handling lye.
