Joel,

The OP is happy with your solution so this is not meant as a critique.

I had to make your ranges Absolute in Rows as well as Columns to stop them
indexing when I dragged the formula on the fill handle, (ie $A$1:$A10000),
otherwise it missed some data.

Even with only the years 1980 - 1983, with Jan - Dec it took about 5 seconds
to update on my system at every data entry because it was calculating
480,000 times.

It would seem that this is a case where you were right in the ~misc group
(http://tinyurl.com/5lamuk) whereby, as Bob Philips said, VBA *can* be
faster in some instances, although you seemed be making your statement in
~misc general as if VBA was *always* faster.

You can do this with a sumproduct formula

Put in row 1 starting in column F the years 1980. Put in Column E the
names
of the months starting in Row 2. Make the months names either all 3
characters (Jan, Feb,MAR) or spelled out completely (change MMM below to
MMMM). You have a mixture off both type month names in your data.

Put the following formula in cell F2

=SumProduct(--(year($A1:$A10000)=F$1),--($E2 =
text($A1:$A10000,"MMM")),$B1:$B10000)
