For your sanity and mine, I have put together a soap calculator spreadsheet. You tell it the precision of your scale, how much of each fat you want (sorry, you have to specify the saponification value too, but there's a reference chart included), and your target lye discount.

You can easily scale the recipe arbitrarily.
