I found the article from Conde Nast's Portfolio magazine. SJP's made far more than even Candace Bushnell and producer Michael Patrick King!
Sex and the City: The Smackdown

April 2008 Issue
It's been four years since HBO retired the popular series and Carrie, Big, and the rest of the crew had to audition in a post-
S.A.T.C. world. Some have had more success than others.
Sarah Jessica Parker
Market value: About $25 million
Parker had the highest profile among the
S.A.T.C. cast going into the series, and it has only risen from there. The deals started materializing while she was still playing Carrie Bradshaw, including a gig signed in 2000 to be the face of beauty company Garnier and a big contract with the
Gap in 2004. (She was replaced by singer Joss Stone after three fashion seasons.) Along the way, Parker also signed on to make perfumes with Coty for what
Ad Age estimated at $7 million annually, and to design clothes for retailer Steve & Barry's. Parker's representatives say she has earned more than $1 million per film project.
Kim Cattrall
Market value: About $10 million
Cattrall's most publicized marketing score was a deal to be the spokeswoman for
Liz Claiborne's Spark Seduction perfume. The actress, who played the publicist Samantha, also got as much as $750,000 to promote a low-calorie Bacardi rum, about $300,000 for an overseas TV spot for
Nissan, and another $300,000 for a Tetley tea commercial, according to ad-industry executives. Cattrall's two book advances, says one literary agent, earned her about $500,000 apiece. Producers say she got about $400,000 to make the HBO documentary
Sexual Intelligence. Cattrall has done some stage work and acted in a few small foreign films. For her role in the 2005
Ice Princess, she earned about $600,000, say film-industry sources.
Kristin Davis
Market value: About $4.5 million
Davis' role as the prim Charlotte has translated mainly into mom gigs. She has been in a trio of kids' films—
The Adventures of Sharkboy and Lavagirl, The Shaggy Dog, and
Deck the Halls—with a per-film paycheck of about $600,000, according to sources in the film industry. On the marketing front, Davis snagged a spokeswoman deal with Maybelline; she also got about $600,000 for appearing in print ads for Weatherproof Garment Co. and about $1 million for co-starring in a 7Up campaign with Cynthia Nixon, says an ad executive.
Candace Bushnell
Market value: About $3.25 million
HBO reportedly paid next to nothing for the rights to Bushnell's book
Sex and the City, but the writer received an advance of between $1 million and $3 million for her 2005 novel,
Lipstick Jungle, says a literary agent. More recently, Bushnell sold NBC the rights to
Lipstick Jungle for approximately $25,000 up front and $250,000 at the start of production, plus royalties, according to a producer.
Cynthia Nixon
Market value: About $2.5 million
Pre-
S.A.T.C., Nixon, who played the lawyer Miranda, was primarily a stage actress. Post-
S.A.T.C., she has largely stuck to artsy projects. Three notable ones are HBO's
Warm Springs (in which she played Eleanor Roosevelt opposite Kenneth Branagh's F.D.R.), the 2004 TV movie
Tanner on Tanner, and the indie flick
Little Manhattan. Nixon probably earned less than $1 million total for those roles, estimates an entertainment-industry lawyer. For the 7Up spot she did with Davis in 2004, she made about $1 million, say advertising executives. In 2006, she starred in a $1 million campaign for the online grocer FreshDirect, as did film director Spike Lee.
Darren Star
Market value: About $1.5 million
The
S.A.T.C. co-creator is still searching for his next big thing. His failed shows include
Kitchen Confidential, Manchild, Miss Match, and
Runaway. He has a deal with Sony Pictures Television that translates into more than $250,000 a pilot, according to a producer. His latest brainchild,
Cashmere Mafia, on ABC, repeats the
S.A.T.C. formula of following the lives of four female friends.
Michael Patrick King
Market value: More than $250,000
King was the executive producer of
S.A.T.C. His publicist says his per-pilot fee is more than $250,000. He has attempted to launch just one series since 2004:
The Comeback, for HBO, with Lisa Kudrow as a failed actress trying to revive her career. It lasted thirteen episodes.
Patricia Field
Market value: About $1,000 a day
Field's artful styling on
S.A.T.C. helped her land jobs everywhere, from television shows like
Hope & Faith to feature films like
The Devil Wears Prada, with a daily fee of about $1,000, says a booking executive. She is now working on
Cashmere Mafia, with former
S.A.T.C. producer Darren Star.
The Supporting Men
Market value: More than $19 million
The clear winner is Chris Noth (Carrie's elusive lover Mr. Big), whose per-episode take as detective Mike Logan on
Law & Order: Criminal Intent is in "the upper $300,000" range, his manager says. Not far behind is Kyle MacLachlan, who played Charlotte's first husband, Trey. MacLachlan now earns about $125,000 an episode as a dentist on
Desperate Housewives, according to film-industry research estimates. Heartthrob Jason Lewis, who played Smith, Samantha's young boyfriend, has had a recurring role on ABC's
Brothers & Sisters. John Corbett (Aidan) has been in several films, including
Raising Helen. Comic Mario Cantone (Anthony) is the lone lad to have parlayed his
S.A.T.C. gig into a promotional payday. His voice-over contract for hair-care line Sunsilk is probably worth as much as $200,000, says an ad executive.
