Default How do you estimate FG

I have been brewing from kits with LME and speciality grains. The label on the box indicates OG of the wort and attenuation of the yeast. How do I estimate FG?

Default

1 + FG = (OG -1) * (1-attenuation) or working in points, FG = OG - OG*Attenuation

An OG of 1.048 with attenuation of 75% means a FG of 1.012 Anything within 2-3 points is good.
