Teach Soap

which is more accurate. b/c i put the same numbers in each of them and got different lye amts. and water amts.

The SAP value of an oil or butter varies from harvest to harvest, season to season and year to year. Since there is a variance in SAP for each oil on soap calcs due to this difference, I prefer to use the same one each time. I started with The Sage because Brambleberry didn't have one til recently.

You can set the % of water on soap calc, so it will reflect their default number if you didn't alter it, where BB probably has a different default number.
The amount of lye can vary slightly, as every oil has a slight range. Depending on what chart they go by, it may be a tad different/off than another calculator. It should only be hundredths of a difference, so if it is more than that you should redo it and see if you made any mistakes in inputting (like a wrong oil or an oil instead of a butter etc.).
In the end, you have to decide which calculator(s) you feel is best for you. I personally like the soap calc the best, but I use BB to see their recommendations for the amount of fo to use since they do not post the max use rates on their site.

eta; I got a phone call while writing this and forgot to hit enter until I returned, so I didn't see that you already had a good answer. Sorry, wasn't trying to talk over Irena!
