What’s the best soap calculator to use?

There are many available these days, and I always used Soap Calc however it’s no longer available.

My favourite to use now is Lye Calc

I find it simple, well researched and I really enjoy the ‘beginner’ and advanced’ options.

I have no affiliation with Lye Calc, just recommending it here due to the unavailability of my old favourite Soap Calc.

There are phone app soap calculators also available if you prefer, just check them out and see which ones you like best.

Happy calculating!
