As a general rule of thumb you can ballpark ad income at $0.50 - $1 CPM, in the financial space you can maybe get a bit higher than that maybe $2-3. This is based on using an automated system like Adsense, if you're going to have your own sales people selling ads you can get quite a bit higher (i.e in the $10-$80 range) but obviously costs are going to be quite a lot higher as well. A good approach is to see how much it costs to advertise on sites similar to yours and multiply that by around 0.6.
