It looks like this.

From the original poster on Reddit (where you can also find trivia and a more complex breakdown):

Confirmed sex (either by strong innuendo or plain admission) = 1. Unconfirmed sex (e.g., ‘I dated a guy…’) = 0,5.

Chandler: 10.5 sex partners
Ross: 14 sex partners
Monica: 14.5 sex partners
Rachel: 15.5 sex partners
Phoebe: 32.5 sex partners
Joey: 51.5 sex partners

Well, at least now we know.
