I have a colleague that asked help with a formula - He would like to add 3
cells up and then multiply it by 20% and add that into the total

I tried =sum(a1:a3)+(a1:a3*.20)
but it didn't work

Can this be done in one cell or do you have to use two cells to calculate
this.

thanks

=SUM(a1:a3)*1.20

OK, this will work 2 ways. You're looking for =sum(a1:a3)+sum(a1:a3)*.20

but, much easier as: =sum(a1:a3)*1.2. :-)

Try this one:
=sum(A1:A3)*1.2

Hi. One way:

=SUM(A1:A3)*(1+20%)

As you can see, there are many ways to achieve the same result.
To support your original attempt method:

=SUM(A1:A3)+(SUM(A1:A3)*0.2)

In one cell..................

=SUM(A1:A3)*1.2

Or if the 20% is variable and entered in B1...............

=SUM(A1:A3)+SUM(A1:A3)*B1
