Your Ultimate Cost Using An Inadequate Excel Model

There are different aspects when thinking about the cost of using an Excel model that’s not right for the job…

  • It’s time consuming
  • It’s frustrating to use
  • You can’t grow your business, because it is not scalable
  • Errors lead to more errors
  • It is demanding to work with
  • The lack of documentation makes it even harder to use

  • You can’t trust the data and the results of your model
  • You can’t make $1m decisions with that level of uncertainty


The cost of these errors is not just the time wasted or the time needed to redo your work.

The cost is the level of frustration.

The motivation for the user to cope with faulty or clunky models.

The ultimate cost can be a huge loss for your company.
Which can result in the loss of your job or the demise of your whole business.

Here’s what you could do to avoid this…

      a. Strategise your ideas and concepts

      b. Decide whether it is a one-off calculation or a sophisticated model

      c. Document your assumptions

      d. Clearly structure your workbook be separating your assumptions, parameters and results

      e. Build in error checks

       f. Colour code your different areas in the model

      g. Protect your calculations

      h. Avoid hard coded values at all cost

       i. Testing through various stakeholders

       j. Document your model

      k. Get your financial model audited

       l. Engage a modelling expert


Start the next financial year with well documented and audited models to make sure that your business is safe.
