There is no such thing as "perfect keyword density."

Yes, your page has to include the primary keyword/phrase you're targeting. But no, a calculator is not an SEO tool. :-)

Write naturally. Write for humans. Include appropriate keywords and synonyms where you can. But don't worry about word counts and percentages and all that other stuff.

To check your keyword density you check this formula:

Density = ( Nkr / ( Tkn -( Nkr x ( Nwp-1 ) ) ) ) x 100
Density = your keyword density
Nkr = how many times you repeated a specific key-phrase
Nwp = number of words in your key-phrase
Tkn = total words in the analyzed text
