Final Profit Calculations?

How is it calculated?

Is Commerce Mastery bonus calculated before Letters of Guarantee? Or after? Or do they add together?

The bonus is additive.

So Rank 1 Commerce Mastery with a Fine Imp Letter gives 100% + 15% + 150% = 265% of the original profit.

Also, this is already on the Commerce Mastery page. Should it go here too?

This is the Commerce Mastery page, and it's not here. If you mean the Commerce System page, I didn't notice. It would be nice for it to be here, and also on the Letter of Guarantee page-- thanks!

Yeah, I meant the main Commerce page.

I guess I just liked saying Commerce Mastery repeatedly!
