A formula that is: if the sum is this, then muliply by this?

[Jenny]

I want a formula that will calculate like this:

If the total in this cell is between 75,000 and 99,999 then muliply it by
..30. If it's between 100,000 and 149,999 then muliply it by .80. Is this
possible?

one way:

=IF(OR(A1<75000,A1>=150000),"out of range",IF(A1<100000,0.3,0.8)*A1)

This lookup formula will do it.
=LOOKUP(SUM(A7:A10),{0,75000,100000,150000},{0,0.3,0.8})

=LOOKUP(SUM(A7:A10),{0,75000,100000,150000},{0,0.3,0.8})*sum(a7:a10)

Note that this gives #N/A for values >150000. IF it's desired that those
values return 0, then you could use

=LOOKUP(SUM(A7:A10),{0,75000,100000,150000,1E+307},{0,0.3,0.8,0}) *
SUM(A7:A10)

Try this formula ...

=if(and(A1>=75000,A1<=99999),0.30*A1,if(and(A1>=100000,A1<=149999),0.80*A1,"")
