As of March 21st, 2016, Autodesk Inventor Professional subscription prices will be the same as Autodesk Inventor pricing and the product line will be consolidated to Inventor LT and Inventor.
The new Autodesk Inventor will have all the features of Inventor Professional at the same price of Inventor, which is 40% cheaper and users can subscribe monthly, quarterly, annually, 2 years or 3 years.
The new features and pricing model is quite aggressive from Autodesk. In terms of competitive price points against Solidworks, you could pretty much subscribe to Inventor for a year for around the same price as the maintenance renewal of Solidworks Professional but get the features of Solidworks Premium and not have to pay the upfront cost of a Perpetual Licence.
