If I have read your function correctly


=a1*80*b1*55*if(d1=”Y”,1.05,1) *if(e1=”Y”,1.05,1) *if(f1=”Y”,1.1,1) *if(g1=”Y”,1.025,1)

Of course the 1.05 could be referenced by the cells which hold the values in case you had to update them in the future, but if what you do works, that’s all that matters
