I found a great little tool earlier today on Modern Life is Rubbish, the AdCalc.

This simple tool allows publishers to calculate approximately they are getting paid per click. It will also let you “find out how much you’re making per week, month, and even per year - assuming your traffic remains steady and the bottom doesn’t fall out.”

The AdCalc is especially good for web publishers who run their own ad networks through programs like phpAdsNew. You can figure out what to charge your advertisers and give them better CTR, CPM numbers.

I’ve gone ahead and added this tool to our webmaster & blogger tools directory, ChartingyourWealth.com.
