I just did a google search on VAM Calculator and it returned loads of hits...
Can't check any out on work pooters though so can't recommend any!0 

Here is an article on VAM

Using the formula shown I seem to score just under 3 Watts per Kilo, but my results are from quite a short hill0

At least Dr Ferrari acknowledges that gradient (strongly) affects VAM, which he didn't a few years ago.Jeff Jones

At last and you dont need to be a doctor to see this yourself. I can monster up a climb until it gets to a "certain" level then it all drops of. most people i know are the same.
I know measuring VAM with a powermeter can show an increase as the gradient rises but iom talking about the observed effect(not measured) of increasing the gradient beyond a tipping point0 
Loving the idea that I can work out my figures the ghetto way by just riding up a hill fast with my stopwatch but my head was hurting trying to do the maths on this! Found this page though which is basic but does it for me

I have one of the mavic computers which have an altimeter etc and works out the gradient (shown as %) and vam etc handy tool if you ride well.0
