You could avoid the need for ATP by changing =MROUND(D3*G3*1.1,100) to
=ROUND(D3*G3*1.1,-2)

The OP did, however, want to round *up*, so =ROUNDUP(D3*G3*1.1,-2) or
=CEILING(D3*G3*1.1,100)

Hi,

Try this.

=MROUND(D3*G3*1.1,100)

If you are using any version other than Excel 2007, you will need to
install the Analysis Toolpak from Tools Addins for the MROUND()
function to work

...but not for me. I can do it on a calculator, but not in Excel. This
is
what I'm trying to do: the sum of (D3*G3) + 10%. The numbers a D3 =
21.6, G3 = 100, so the answer should come to 2,376. And then I want
to round
up that number to become 2,400. Thank you. Connie
