A nifty little online calculator for estimating the return on investment for social network campaigns. It was built for non-profits, but can be leveraged for for-profits as well. It works a lot like a online mortgage or budget calculators. Plug in your assumptions and voila!
It’s helpful to have a tool to compare social networking ROI with other more established methods. Also, it shows the cost of social networking and hey, guess what? it’s not free.
