Someone should build a webpage that does this:

1. Enter salary of engineer.

2. Enter cost per engineer of product (subscription, one time, etc.).

3. Enter required minutes to make worth your time (setup per employee can be factored in).

This may already exist, but if it doesn't it could be a useful tool for Saas companies. Something you could drop into emails to potential customers ("see how much you would save").

Would pay for this monthly if it works.
