How much is a reasonable increase in salary?

I'm a consultant looking at new jobs. I bring with me tools/processes that I created, that improve the efficiency of each tech consultant in a company's team by about 40%, and increase profit per consultant from the usual $100K to $160K. How much more starting salary can I realistically ask for?

• (1) I have tested my tools/processes with 12 volunteers (1 reported 59% efficiency upgrade, 10 reported 48-54%, 1 reported 40%). (2) My target companies have between 8-20 consultants of the sort my automation helps. (2) The average salary for my function and experience (without the automation experience) is between $100-120K.

• Answer:

  The question is what do you feel your services are worth?  You can always go off of the market rate of a consultant that specializes in your field.  You can charge by the hour or by the project if you are independent.  Or if you are an internal consultant (meaning you work for an organization) you can aim on the higher end of your salary and negotiate from there.  Only you know how much effort you put into your work and the types of ethics that drive your quality.  The question I have for you is, if you are already a consultant, and I am assuming you are working externally, why would you be looking for a job?  Why not continue to work for yourself?  If you're an internal consultant have you ever thought about consulting for yourself.  If this isn't the case and you do work for an organization or plan to in the near future, why not shoot for the hirer end of what your industry pays.   You seem to bring value, have the ability to produce results you can quantify, and have experience in a specific niche. Long story short, if you feel your work is worth $160K than your probably right.  If you feel you're work is worth $100K, than you're probably also right.  It really sounds like you'll need to develop your pitch to why you're worth what you are.  Most importantly, believe it yourself.
