Minimal IT cost model

The Minimal IT cost model shows where to look for IT cost savings.

The cost model is introduced in the following newsletters.

Using the model

The model asks 15 questions about your IT costs, how your costs are broken down, and factors that affect your IT costs.

The model explains each of the questions in detail.

Most of the questions are easy to follow. Three of them are a bit more subjective, and may be worth thinking about before you try the model.

  • Business scale is your estimate of the percentage of IT hardware, software and support costs that you can not easily cut back because you have no control over the underlying quantity used, such as the cost of a PC on every desk, or the cost of branch-based computing.
  • Average duplication is your estimate of how many times on average each business requirement is implemented. The sort of things that add to average duplication include:
    • Old systems that have not been decommissioned
    • Systems with overlapping functionality
    For example, if you are running old legacy systems in parallel with a replacement package, you might set this to 1.8 to show that most requirements, but not all, are implemented in both.
  • Average complexity is your estimate of how much more complicated on average your implementation are than they need be. The sort of things that add to average complexity include:
    • Layers of technology wrappers to translate to old or new standards
    • Unnecessary intermediate processes
    • Functionality within business systems that has no business function but is required to get around idiosyncrasies of the technology
    For example, if you use a lot of intermediate servers because of some now defunct file transfer method, you might set this to 1.3 to show that every system carries a lot of additional code that could be removed.

The first column of figures shows the costs that you entered. They are broken down to estimate how the costs spread over different activities.

The notes show how revised figures are calculated. The cost model provides a key to the notes.

The last three columns show the reduced costs, the saving, and the saving as a percentage of current costs.


We would like to include your figures in our survey, to understand how businesses in different sectors and different countries can reduce their IT costs.

If you would like to take part in our survey, fill in the form below the results on the model, and click on Submit survey.


The model runs entirely on your browser. The figures you enter and your results do not leave your PC. They are entirely confidential.

If you choose to take part in our survey, your figures and your results will be sent to us. We will keep your details confidential. See the survey form for more information.
