About SoapMetrics

Why we built it

When we started looking for a soap calculator, nothing felt accurate enough for how we actually formulate. Other tools were missing oils, had incomplete additive lists, or didn't give us the full picture we needed when adjusting a recipe. So we built SoapMetrics — a calculator focused on precision, a complete listing of oils and additives, and the kind of analysis that helps you understand what your recipe is really doing.

Amy brings the soap-making experience — about 10 years of making soap and selling at craft shows — and knows what matters in real batches. Kevin handles the technical side and keeps pushing to make the calculator clearer, more complete, and easier to use. Together, we're building the tool we wanted from day one.

Soap making software, not only a calculator

The calculator is the starting point. SoapMetrics is also soap making software for saved recipes, batch tracking, inventory, and costs when you are ready to manage more than one formula at a time.
