Simple SoapCalc

Create freely. Calculate confidently.

Soapmaking depends on getting the numbers right. When the math is off, the whole batch is off. Simple SoapCalc takes care of the calculations so you can focus on the craft, not the chemistry.

Describe the soap you want to make. Adjust oils, batch size, or superfat as you explore. Simple SoapCalc responds with precise lye, water, and oil amounts you can trust, every time.

Try asking:
• I want to make a creamy, moisturizing soap for dry winter skin
• Create a beginner-friendly recipe with olive oil, coconut oil, and shea butter (500 g total)
• What kind of soap produces lots of fluffy lather?

You’ll see clear results right away, along with an honest sense of how the soap will behave and feel. Creativity stays open. The calculations stay exact.

No spreadsheets. No second-guessing.
Just safe, well-made soap — calculated in seconds.
