SaaS vs. On Premise TCO Calculator
Created on: Feb 4, 2009 10:55 AM by MichaelStevens - Last Modified: Mar 27, 2009 12:55 PM by MichaelStevens
The purpose of this calculator is to let you quickly compare the total cost of ownership (TCO) of a software-as-a-service (SaaS) solution to the TCO of an on-premise solution. The values this calculator provides are approximations, and can in no way obviate the need for a careful cost/benefit analysis. But they can serve as a first step in determining whether the potential delta between the two approaches is large enough to warrant further investigation.
The calculator presents two results: TCO, and annual costs, which is the sum of the annual licensing/subscription fees, annual management costs, and the total cost of start-up and upgrades amortized over the number of years in the calculation.

The model concurs perfectly with our experiewnce of rolling out on-demand solutions to the SME market. If anything, it slightly over emphasises the benfits in TCO.

Downloaded and tried the excel. I was checking out the TOC for cyn.in collaboration software On-Premise Appliance and cyn.in SaaS Large pack.
The excel couldn't help much, because cyn.in SaaS pricing is not user based and integration and custom development are charged on case-to-case basis and requirement.
