Awareness of the existence of the Windows Azure Platform TCO and ROI Calculator remains pretty low based on some conversations I have had lately at events.

It is available in both online and offline versions and aims to help measure the potential savings of product development or migration to the Windows Azure Platform.

Lets take a quick example of a brand new car insurance site (Based on my depth work with… car insurance sites!). In brief:

Which left me with the following ROI and

Enjoy. And share here anything good or bad it throws up. Thanks.
