Not that I am aware of, but it is trivial to calculate:

([character SP] - 5 000 000) / 500 000 \* ([value of Skill Injector] - [value of Skill Extractor])

Right now that is something like:

([character SP] - 5 000 000) / 500 000 \* (749M ISK - 326M ISK) or;

([character SP] - 5 000 000) / 500 000 \* (423M ISK)

So a character with 20M SP right now is worth:

(20 000 000 - 5 000 000)/500 \* 423M ISK or 12.69B ISK

if you strip the SP to sell.

I guess I can make a chart:
