Hi!

Trying to get detailed info is sometimes worse than pulling teeth! <g

If your mileage data is in column A and you add new data to it on a regular
basis:

=AVERAGE(A:A)

Just don't put the formula in column A.

I am using my Excel to enter vehicle mileage and fuel cost information. I
added a row for the overall average of fuel mileage for all fuel entries
and
would like Excel to keep the overall average for me without having to
enter
it manually.
Thanks!

Hi!

What's your definition of a running average?

What do you want to average and where is it?
