I know it says it can calculate liquid soap, but I haven't used it yet. Are you a member of Bekka's Yahoo group? If not, pm me and I'll shoot you the URL. She's phenominal at calc'ing for the cream soaps. When I did my first batch, I think she had me start out adding a tablespoon at a time until I got it the consistency I wanted (if I understood your question correctly). Also, I have a calculator that is specific for the cream soaps. I'll have to find the URL but I think I downloaded it for $9.00. It's the one that's always recommended on the Whisk.
