I had trouble learning SoapCalc also. One day I got mad at myself and made myself use SoapCalc until it made sense. Once it did, I can now use any
soap calculator out there, even the advanced ones for liquid soap formulations.
Hang in there on learning SoapCalc. It really is simple once you get the hang of it. You just need to take one entry at the time. If you are measuring in ounces, start there. Click the ounces option. Type in how many ounces of oil you intend to use. Then look down at the part of the chart that has oils and whether to use % or ounces. Click ounces.
Then, choose whether you are using NaOH or KOH, and which kind of KOH.
Determine the amount of SF you are using. It is automatically set for 5, but you can change it. Then how much fragrance/EO you are using.
Once I got the above set, the rest was easy. Choose the fats(read twice, click once). Set the amount. Add additions and any specific notations at the bottom. (Like cool lye water to 110 degrees or any other specific instructions.)
Hit the calculate button, and look for any red info(like your oils do not add up to 100%). Fix any mistakes.
Then click view and print recipe. Give your soap a name with a date if you are making it right away. If I got the recipe from someone else, I put initials of the source so I know who to give credit to. Example: for a recipe from here, I use SMF: EG for Soapmaking Forum: Efficacious Gentleman. It comes out in a color coded chart that is easy to use. I print these out and punch holes for my soaping binder.
I use the areas at the bottom to take specific notes such as lye water was X degrees or it took X minutes to trace. I then put the dates it was molded, cut, etc on that page. I also put notes on what I think about the soap on there and any specific responses from others.
Being able to compare formulas, know my numbers of hardness, conditioning and such, and plenty of room for notes at the bottom makes SoapCalc my favorite calculator for bar soaps.
