How much lye to fragrance oil?

[afedericojr]

On the lye calculator, what do I choose as an oil for fragrance such as:

If I don't account for the FO, will it really throw off the batch?

You do not need to account for the FO, at least I do not, just add the FO at the recommended percentage by the manufacturer.

same as above

if you use soapcalc, you can put the amount of fo you want and it will calculate automatically for you depending on the size of your batch..
