Given A - R ordered then

=T50/offset(F3,code(I50)-65,0)

for case insensitive

=T50/offset(F3,code(ucase(I50))-65,0)

You could do away with I3:I20

sorry, hit send too fast
=T50/INDEX(F3:I20,MATCH(I50,I3:I20,0),1)

where I3 contains A, I4 contains B and I50 contains B

finds B in range f3:i20 then returns the value from F4 and then divides it
by T50

if there is only one occurance of I50 in the range I3:I20, then they
would be equivalent.

I don't have an opinion on which is preferred

are these 2 equivalent and if so, which is preferred? there are a few
hundred of these formulas in a workbook and i'd like to change the 2nd
one to the first one.

=T50/SUMIF($I$3:$I$20,I50,$F$3:$F$20)
=T50/(LOOKUP(I50,$I$3:$I$20,$F$3:$F$20))
