I am trying to do an NPV calc for 180 months with varying amounts, but a flat
interest rate. Is there a way to do this in Excel without calculating it in
pieces (180/29)?

The 29 does not have to be separate months. Each of the 29 arguments can be
a range, and you likely only need one argument with a single range, eg:-

=NPV(0.1,A1:A180)

See the Function Help for more info.

Thank you! This solved my problem. I was in a time crunch and I appreciate
your quick response.
